Description of the Related Art

In the nascent era of RNA vaccines and therapeutics, the ability to express multiple proteins from a single RNA transcript and the ability to control translation product stoichiometry from a single polycistronic mammalian RNA is becoming increasingly important. For example, the current Pfizer/BioNTech and Moderna COVID-19 vaccines employ a messenger RNA (mRNA) that encodes for a single polypeptide (the spike protein) which acts as the antigen for the immune response. As mRNA vaccines and therapeutics become increasingly common and complex, there will be an increasing need for methods and compositions enabling expression of multiple polypeptides from a single RNA. Another example is the recent development of protein interaction circuits such as CHOMP. These circuits can be introduced into a cell via a mRNA, bypassing most of the central dogma processes. Proper circuit constituent stoichiometry is important for a reliable and reproducible circuit function.

Expression of multiple proteins can be done by co-introduction of multiple plasmids, RNAs, viral vectors or similar genetic constructs into a pool of cells. Such methods are problematic because the ratios of individual components in each cell do not perfectly correlate with the ratios of the parent mixture due to inherent stochasticity in the co-introduction methods. Controlling gene product stoichiometry is often done by expressing multiple RNAs from promoters of varying strengths or by titrating promoter-specific chemical inducers. These approaches, however, are not applicable for polycistronic mRNAs since transcription is bypassed.

Current technologies that allow for polycistronic expression from mammalian mRNA have limited capabilities for tuning translation stoichiometry from genes on the same mRNA. For example, a viral Internal Ribosome Entry Site (IRES) can provide an additional ribosome flux for expression of a secondary product, but the expression is severely attenuated. Additionally, IRES sequences are long, which limits other sequence content that can be included with the capacity of a vector. Another option is to link the polypeptides with a self-cleaving viral 2A sequence (such as P2A). This approach generally achieves higher expression compared to IRES but the translation rate is locked at equivalence. Additionally, 2A sequences introduce non-native amino acids to each polypeptide, which in many cases negatively affect the proper function of the protein.

There is a need for compositions and methods enabling expression of multiple proteins from a single mRNA which provide a user-friendly framework to arbitrarily and predictably tune translated product stoichiometry.

The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein and made part of the disclosure herein.

Disclosed herein include engineered cells. In some embodiments, the engineered cells comprise: a nucleic acid composition disclosed herein.

Definitions

Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. See, e.g. Singleton et al., Dictionary of Microbiology and Molecular Biology 2nd ed., J. Wiley & Sons (New York, N.Y. 1994); Sambrook et al., Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Press (Cold Spring Harbor, N.Y. 1989). For purposes of the present disclosure, the following terms are defined below.

As used herein, the terms “antigen” or “immunogen” are used interchangeably to refer to a substance, typically a protein, which is capable of inducing an immune response in a subject (e.g. a mammal, such as a human). The term also refers to proteins that are immunologically active in the sense that once administered to a subject, either directly or in the form of a nucleotide sequence or vector that encodes the protein, is able to evoke an immune response of the humoral and/or cellular type directed against that protein or a variant thereof.

As used herein, “sequence identity” or “identity” in the context of two nucleic acid or polypeptide sequences makes reference to the nucleotide bases or residues in the two sequences that are the same when aligned for maximum correspondence over a specified comparison window. Methods of alignment of sequences for comparison are well known in the art. Various programs and alignment algorithms are described in: Smith & Waterman, Adv. Appl. Math. 2:482, 1981; Needleman & Wunsch, J. Mol. Biol. 48:443, 1970; Pearson & Lipman, Proc. Natl. Acad. Sci. USA 85:2444, 1988; Higgins & Sharp, Gene, 73:237-44, 1988; Higgins & Sharp, CABIOS 5:151-3, 1989; Corpet et al., Nuc. Acids Res. 16:10881-90, 1988; Huang et al. Computer Appls. in the Biosciences 8, 155-65, 1992; Pearson et al., Meth. Mol. Bio. 24:307-31, 1994; and Altschul et al., J. Mol. Biol. 215:403-10, 1990 (the content of each of these references is incorporated herein in its entirety).

When percentage of sequence identity or similarity is used in reference to proteins, it is recognized that residue positions which are not identical often differ by conservative amino acid substitutions, where amino acid residues are substituted with a functionally equivalent residue of the amino acid residues with similar physiochemical properties and therefore do not change the functional properties of the molecule. A functionally equivalent residue of an amino acid used herein typically can refer to other amino acid residues having physiochemical and stereochemical characteristics substantially similar to the original amino acid. The physiochemical properties include water solubility (hydrophobicity or hydrophilicity), dielectric and electrochemical properties, physiological pH, partial charge of side chains (positive, negative or neutral) and other properties identifiable to one of skill in the art. The stereochemical characteristics include spatial and conformational arrangement of the amino acids and their chirality. For example, glutamic acid is considered to be a functionally equivalent residue to aspartic acid in the sense of the current disclosure. Tyrosine and tryptophan are considered as functionally equivalent residues to phenylalanine. Arginine and lysine are considered as functionally equivalent residues to histidine.

The term “substantially identical” as used herein in the context of two or more sequences refers to a specified percentage of amino acid residues or nucleotides that are identical or functionally equivalent, such as about, at least or at least about 65% identity, optionally, about, at least or at least about 70%, 75%, 80%, 85%, 90%, 95%, or 99% identity over a specified region or over the entire sequence.

As used herein, the term “variant” refers to a polynucleotide or polypeptide having a sequence substantially similar or identical to a reference (e.g., the parent) polynucleotide or polypeptide. In the case of a polynucleotide, a variant can have deletions, substitutions, additions of one or more nucleotides at the 5′ end, 3′ end, and/or one or more internal sites in comparison to the reference polynucleotide. Similarities and/or differences in sequences between a variant and the reference polynucleotide can be detected using conventional techniques known in the art, for example polymerase chain reaction (PCR) and hybridization techniques. Variant polynucleotides also include synthetically derived polynucleotides, such as those generated, for example, by using site-directed mutagenesis. Generally, a variant of a polynucleotide, including, but not limited to, a DNA, can have at least, or at least about, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or more sequence identity to the reference polynucleotide as determined by sequence alignment programs known in the art. In the case of a polypeptide, a variant can have deletions, substitutions, additions of one or more amino acids in comparison to the reference polypeptide. Similarities and/or differences in sequences between a variant and the reference polypeptide can be detected using conventional techniques known in the art, for example Western blot. A variant of a polypeptide can have, for example, at least, or at least about, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or more sequence identity to the reference polypeptide as determined by sequence alignment programs known in the art.

Standard techniques can be used for recombinant DNA, oligonucleotide synthesis, and tissue culture and transformation (e.g., electroporation, lipofection). Enzymatic reactions and purification techniques can be performed according to manufacturer's specifications or as commonly accomplished in the art or as described herein. The foregoing techniques and procedures can be generally performed according to conventional methods well known in the art and as described in various general and more specific references that are cited and discussed throughout the present specification. See, e.g., Sambrook et al., Molecular Cloning: A Laboratory Manual (2d ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y. (1989)), which is incorporated herein by reference for any purpose. Unless specific definitions are provided, the nomenclatures utilized in connection with, and the laboratory procedures and techniques of, analytical chemistry, synthetic organic chemistry, and medicinal and pharmaceutical chemistry described herein are those commonly known and used in the art. Standard techniques can be used for chemical syntheses, chemical analyses, pharmaceutical preparation, formulation, and delivery, and treatment of patients.

The term “construct,” as used herein, refers to a recombinant nucleic acid that has been generated for the purpose of the expression of a specific nucleotide sequence(s), or that is to be used in the construction of other recombinant nucleotide sequences.

As used herein, the terms “nucleic acid” and “polynucleotide” are interchangeable and refer to any nucleic acid, whether composed of phosphodiester linkages or modified linkages such as phosphotriester, phosphoramidate, siloxane, carbonate, carboxymethylester, acetamidate, carbamate, thioether, bridged phosphoramidate, bridged methylene phosphonate, bridged phosphoramidate, bridged phosphoramidate, bridged methylene phosphonate, phosphorothioate, methylphosphonate, phosphorodithioate, bridged phosphorothioate or sultone linkages, and combinations of such linkages. The terms “nucleic acid” and “polynucleotide” also specifically include nucleic acids composed of bases other than the five biologically occurring bases (adenine, guanine, thymine, cytosine and uracil).

The term “contrast enhanced imaging” or “imaging”, as used herein indicates a visualization of a target site performed with the aid of a contrast agent administered to the target site to improve the visibility of structures or fluids by devices process and techniques suitable to provide a visual representation of a target site. Accordingly a contrast agent is a substance that enhances the contrast of structures or fluids within the target site, producing a higher contrast image for evaluation.

The term “ultrasound imaging” or ultrasound scanning” or “sonography” as used herein indicate imaging performed with techniques based on the application of ultrasound. Ultrasound can refer to sound with frequencies higher than the audible limits of human beings, typically over 20 kHz. Ultrasound devices typically can range up to the gigahertz range of frequencies, with most medical ultrasound devices operating in the 1 to 18 MHz range. The amplitude of the waves relates to the intensity of the ultrasound, which in turn relates to the pressure created by the ultrasound waves. Applying ultrasound can be accomplished, for example, by sending strong, short electrical pulses to a piezoelectric transducer directed at the target. Ultrasound can be applied as a continuous wave, or as wave pulses as will be understood by a skilled person.

Accordingly, the wording “ultrasound imaging” as used herein can refer to in particular to the use of high frequency sound waves, typically broadband waves in the megahertz range, to image structures in the body. The image can be up to 3D with ultrasound. In particular, ultrasound imaging typically involves the use of a small transducer (probe) transmitting high-frequency sound waves to a target site and collecting the sounds that bounce back from the target site to provide the collected sound to a computer using sound waves to create an image of the target site. Ultrasound imaging allows detection of the function of moving structures in real-time. Ultrasound imaging works on the principle that different structures/fluids in the target site will attenuate and return sound differently depending on their composition. A contrast agent sometimes used with ultrasound imaging are microbubbles created by an agitated saline solution, which works due to the drop in density at the interface between the gas in the bubbles and the surrounding fluid, which creates a strong ultrasound reflection. Ultrasound imaging can be performed with conventional ultrasound techniques and devices displaying 2D images as well as three-dimensional (3-D) ultrasound that formats the sound wave data into 3-D images. In addition to 3D ultrasound imaging, ultrasound imaging also encompasses Doppler ultrasound imaging, which uses the Doppler Effect to measure and visualize movement, such as blood flow rates. Types of Doppler imaging includes continuous wave Doppler, where a continuous sinusoidal wave is used; pulsed wave Doppler, which uses pulsed waves transmitted at a constant repetition frequency, and color flow imaging, which uses the phase shift between pulses to determine velocity information which is given a false color (such as red=flow towards viewer and blue=flow away from viewer) superimposed on a grey-scale anatomical image. Ultrasound imaging can use linear or non-linear propagation depending on the signal level. Harmonic and harmonic transient ultrasound response imaging can be used for increased axial resolution, as harmonic waves are generated from non-linear distortions of the acoustic signal as the ultrasound waves insonate tissues in the body. Other ultrasound techniques and devices suitable to image a target site using ultrasound would be understood by a skilled person.

Stoichiometric Expression of Messenger Polycistrons by Eukaryotic Ribosomes

Whereas prokaryotes have evolved to routinely produce multiple proteins from a single polycistronic mRNA, due to their ability to initiate translation at mRNA-internal ribosome binding sites, mammalian translation has evolved to mainly produce single proteins from individual mRNAs. As such, mammalian translation lacks the strategies for polycistronic expression and stoichiometry control. Mammalian (and other eukaryotic) ribosomes are loaded on the 5′ end of mRNA which then scan the mRNA until they encounter a translation initiation site (TIS), consisting of the start codon (e.g., AUG) and the surrounding nucleotide “context”. The TIS sets the translational reading frame and initiates translation. Once a ribosome encounters a stop codon, it terminates translation and disengages the transcript, preventing any potential downstream open reading frames (ORFs) from being translated.

Not all eukaryotic translation initiation sites are equal in strength, however, which can cause ribosomes to miss the translation initiation to varying frequency. This apparent defect is utilized by mammalian cells to downregulate protein expression. By employing short ORFs (uORFs) upstream of the gene of interest (GOI), a portion of the ribosome flux is diverted away from GOI, downregulating the translation of GOI. It is unclear if these uORFs produce functional proteins.

The methods and compositions provided herein, in some embodiments, replace synthetic uORFs with longer, functional proteins. In some embodiments, these payload proteins lack internal start codons to prevent unintended internal translation initiation. In case the upstream ORF does contain internal start codons there are several strategies that can be employed with the methods and compositions provided herein to eliminate or reduce unintended internal initiation such as, for example, synonymous codon replacement, mutating the translation initiation “context” making initiation unfavourable or replacement of internal methionines with functionally and structurally similar amino acids. By chaining ORFs this way and varying the translation initiation strength in front of the uORF polycistronic expression of multiple functional proteins can be achieved with tunable translation rates and without the addition of non-native amino acids. This framework, termed “Stoichiometric Expression of Messenger Polycistrons by Eukaryotic Ribosomes” (SEMPER), was employed to construct a single optimized multigene expression cassette for production of gas vesicles in mammalian cells as proof of principle (Example 1).

Gas vesicles (GVs) are gas-filled protein nanostructures natively produced by aquatic prokaryotes for buoyancy regulation. They have recently been demonstrated to function as the first genetically encoded ultrasound contrast agents that produce high-resolution contrast. Their heterologous expression has been recently achieved for the first time in bacteria and mammalian cells, enabling molecular imaging of gene expression and enzyme activity in live animals at depths unachievable with optical reporters such as the GFP.

GV production requires the co-expression of multiple GV proteins (Gvps), which in prokaryotes are expressed from polycistronic operons at specific ratios determined by the strength of their respective ribosome binding sites or other regulatory mechanisms. These genes encode one or more structural proteins (e.g. GvpA) and an assortment of accessory proteins required for GV assembly (e.g. GvpN). While heterologous expression in bacteria is straightforward due to their compatibility with prokaryotic operons, co-expression of all the essential GV genes in mammalian cells at the optimal stoichiometry is not trivial and requires specialized strategies. The principal challenge in mammalian expression involves the requirement for high expression of the major structural protein relative to the rest of the Gvps (FIGS. 1A-1B) and the intolerance of the major structural protein to non-native amino acids, which does not allow it to be linked using P2A.

Provided herein are methods and compositions which overcomes all the aforementioned challenges. The disclosed methods and compositions enable expression of multiple proteins from a single mRNA, and provide a user-friendly framework to arbitrarily and predictably tune translated product stoichiometry. There are provided, in some embodiments, compositions. Compositions disclosed herein include nucleic acid compositions, pharmaceutical compositions, engineered cells, mRNA vaccines, and vectors. Disclosed herein include nucleic acid compositions. In some embodiments, the nucleic acid composition comprises: a promoter operably linked to a polynucleotide comprising a first nucleic acid unit and a second nucleic acid unit. In some embodiments, the first nucleic acid unit encodes one or more first unit payload protein(s). In some embodiments, the second nucleic acid unit encodes one or more second unit payload protein(s). In some embodiments, the first nucleic acid unit and the second nucleic acid unit each comprise a 3′ engineered translation initiation site (eTIS) comprising a three-nucleotide tunable element immediately upstream of a start codon. In some embodiments, the promoter is capable of inducing transcription of the first nucleic acid unit and the second nucleic acid unit to generate a polycistronic transcript. In some embodiments, the polycistronic transcript is capable of being translated to generate the one or more first unit payload protein(s) and the one or more second unit payload protein(s). In some embodiments, the eTIS of each of the first nucleic acid unit and the second nucleic acid unit is configured to achieve a predetermined stoichiometry of the one or more first unit payload protein(s) and one or more second unit payload protein(s) in a cell or cell-like environment. The cell-like environment can comprise an in vitro environment configured for protein expression.

In some embodiments, the polynucleotide further comprises n supplemental nucleic acid unit(s), wherein n is an integer greater than zero (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, or a number or a range between any two of these values). In some embodiments, each supplemental nucleic acid unit encodes one or more supplemental unit payload protein(s). Each supplemental nucleic acid unit can comprise a 3′ engineered translation initiation site (eTIS) comprising a three-nucleotide tunable element immediately upstream of a start codon. The promoter can be capable of inducing transcription of the first nucleic acid unit, the second nucleic acid unit, and each supplemental nucleic acid unit, to generate the polycistronic transcript. The polycistronic transcript can be capable of being translated to generate the one or more first unit payload protein(s), the one or more second unit payload protein(s), and the one or more supplemental unit payload protein(s) encoded by each of the n supplemental nucleic acid unit(s). The eTIS of each of the first nucleic acid unit, the second nucleic acid unit, and the n supplemental nucleic acid unit(s) can be configured to achieve a predetermined stoichiometry of the one or more first unit payload protein(s), the one or more second unit payload protein(s), and the one or more supplemental unit payload protein(s) encoded by each of the n supplemental nucleic acid unit(s), in a cell or cell-like environment.

The first nucleic acid unit can be upstream of the second nucleic acid unit. The second nucleic acid unit can be upstream of the n supplemental nucleic acid unit(s). The first nucleic acid unit, the second nucleic acid unit, and the n supplemental nucleic acid unit(s) each can comprise an open reading frame (ORF). The expression levels of unit payload proteins derived from the same nucleic acid unit can be the same or substantially the same. For example, the first nucleic acid unit can encode three first unit payload proteins, and the expression levels of each of the three first unit payload proteins can be the same or substantially the same. In some embodiments, the tunable element modulates the strength of an eTIS of a nucleic acid unit. In some embodiments, the strength of an eTIS of a nucleic acid unit is related to the fraction of the ribosomes scanning the polycistronic transcript that initiate and translate the open reading frame of said nucleic acid unit upon reaching said eTIS. The expression level of a unit payload protein can be inversely related to the number and strength of eTIS situated upstream of the nucleic acid unit from which it derives on the polycistronic transcript. The strength of the eTIS of the first nucleic acid unit can be inversely proportional to the expression level of the second unit payload protein(s). The expression level of the second unit payload protein(s) can be inversely related to the fraction of the ribosomes initiating and translating the open reading frame of the first nucleic acid unit. The strength of the eTIS of the second nucleic acid unit can be greater than the strength of the eTIS of the first nucleic acid unit, and thereby the eTIS of the second nucleic acid unit efficiently captures the ribosomal translational activity that fails to initiate at the eTIS of the first nucleic acid unit.

The tunable element can be selected from the group consisting of ACC, GGG, CCC, UUC, UUU, or any combination thereof. The eTIS of each nucleic acid unit can be tuned via the tunable element such that the unit payload proteins reach a desired stoichiometry. For example, the first unit payload protein(s) and the second unit payload protein(s) can be in a ratio from 1:100 to 100:1 (e.g., 1:1, 1:1.1, 1:1.2, 1:1.3, 1:1.4, 1:1.5, 1:1.6, 1:1.7, 1:1.8, 1:1.9, 1:2, 1:2.5, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, 1:11, 1:12, 1:13, 1:14, 1:15, 1:16, 1:17, 1:18, 1:19, 1:20, 1:21, 1:22, 1:23, 1:24, 1:25, 1:26, 1:27, 1:28, 1:29, 1:30, 1:31, 1:32, 1:33, 1:34, 1:35, 1:36, 1:37, 1:38, 1:39, 1:40, 1:41, 1:42, 1:43, 1:44, 1:45, 1:46, 1:47, 1:48, 1:49, 1:50, 1:51, 1:52, 1:53, 1:54, 1:55, 1:56, 1:57, 1:58, 1:59, 1:60, 1:61, 1:62, 1:63, 1:64, 1:65, 1:66, 1:67, 1:68, 1:69, 1:70, 1:71, 1:72, 1:73, 1:74, 1:75, 1:76, 1:77, 1:78, 1:79, 1:80, 1:81, 1:82, 1:83, 1:84, 1:85, 1:86, 1:87, 1:88, 1:89, 1:90, 1:91, 1:92, 1:93, 1:94, 1:95, 1:96, 1:97, 1:98, 1:99, 1:100 to 1:1, 1.1:1, 1.2:1, 1.3:1, 1.4:1, 1.5:1, 1.6:1, 1.7:1, 1.8:1, 1.9:1, 2:1, 2.5:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, 10:1, 11:1, 12:1, 13:1, 14:1, 15:1, 16:1, 17:1, 18:1, 19:1, 20:1, 21:1, 22:1, 23:1, 24:1, 25:1, 26:1, 27:1, 28:1, 29:1, 30:1, 31:1, 32:1, 33:1, 34:1, 35:1, 36:1, 37:1, 38:1, 39:1, 40:1, 41:1, 42:1, 43:1, 44:1, 45:1, 46:1, 47:1, 48:1, 49:1, 50:1, 51:1, 52:1, 53:1, 54:1, 55:1, 56:1, 57:1, 58:1, 59:1, 60:1, 61:1, 62:1, 63:1, 64:1, 65:1, 66:1, 67:1, 68:1, 69:1, 70:1, 71:1, 72:1, 73:1, 74:1, 75:1, 76:1, 77:1, 78:1, 79:1, 80:1, 81:1, 82:1, 83:1, 84:1, 85:1, 86:1, 87:1, 88:1, 89:1, 90:1, 91:1, 92:1, 93:1, 94:1, 95:1, 96:1, 97:1, 98:1, 99:1, 100:1, or a number or a range between any of these values).

The difference between the steady-state levels of one or more of the first unit payload protein(s), the second unit payload protein(s), and/or the supplemental unit payload protein(s) and the steady-state levels of one or more of the first unit payload protein(s), the second unit payload protein(s), and/or the supplemental unit payload protein(s) can be less than about, or can be greater than about, one order of magnitude. The expression level of the first unit payload protein(s), the second unit payload protein(s), and the supplemental unit payload protein(s) can be related to the strength of the eTIS of the corresponding nucleic acid unit from which it derives. The predetermined stoichiometry can be configured to achieve a therapeutic level of the first unit payload protein(s), the second unit payload protein(s), and the supplemental unit payload protein(s). The predetermined stoichiometry can be configured to achieve efficacious steady-state protein levels of each of the first unit payload protein(s), the second unit payload protein(s), and the supplemental unit payload protein(s).

As used herein, the term “promoter” is a nucleotide sequence that permits binding of RNA polymerase and directs the transcription of a gene. Typically, a promoter is located in the 5′ non-coding region of a gene, proximal to the transcriptional start site of the gene. Sequence elements within promoters that function in the initiation of transcription are often characterized by consensus nucleotide sequences. Examples of promoters include, but are not limited to, promoters from bacteria, yeast, plants, viruses, and mammals (including humans). A promoter can be inducible, repressible, and/or constitutive. Inducible promoters initiate increased levels of transcription from DNA under their control in response to some change in culture conditions, such as a change in temperature.

As used herein, the term “operably linked” is used to describe the connection between regulatory elements and a gene or its coding region. Typically, gene expression is placed under the control of one or more regulatory elements, for example, without limitation, constitutive or inducible promoters, tissue-specific regulatory elements, and enhancers. A gene or coding region is said to be “operably linked to” or “operatively linked to” or “operably associated with” the regulatory elements, meaning that the gene or coding region is controlled or influenced by the regulatory element. For instance, a promoter is operably linked to a coding sequence if the promoter effects transcription or expression of the coding sequence.

In some embodiments, the polynucleotide and/or second polynucleotide encode gas vesicle assembly (GVA) genes and/or gas vesicle structural (GVS) genes capable of forming one or more gas vesicle(s) upon expression in the cell or cell-like environment, such as a plurality of gas vesicles, or a plurality of gas vesicles and a plurality of secondary gas vesicles. The plurality of secondary gas vesicles can comprise distinctive mechanical, acoustic, surface and/or magnetic properties as compared to the plurality of gas vesicles. Two or more of the first unit payload protein(s), the second unit payload protein(s), and/or the supplemental unit payload protein(s) can be capable of forming gas vesicle(s), such as, for example, gas vesicle(s) derived from a species of Anabaena bacteria, Halobacterium salinarum, and/or Bacillus megaterium. Provided herein are nucleic acid compositions encoding gas-filled protein structures (GVPS), also referred to as “gas vesicles” (GVs). The phrases “gas vesicles protein structure” or “GV”, “GVP”, “GVPS” or “Gas Vesicles” as used herein shall be given their ordinary meaning, and shall also refer to a gas-filled protein structure intracellularly expressed by certain bacteria or archea as a mechanism to regulate cellular buoyancy in aqueous environments. GVs are described in Walsby, A. E. ((1994). Gas vesicles. Microbiology and Molecular Biology Reviews, 58(1), 94-144) hereby incorporated by reference in its entirety. The term Gas Vesicle Structural (GVS) proteins as used herein indicates proteins forming part of a gas-filled protein structure intracellularly expressed by certain bacteria or archaea and can be used as a mechanism to regulate cellular buoyancy in aqueous environments. In particular, GVS shell comprises a GVS identified as gvpA or gvpB (herein also referred to as gvpA/B) and optionally also a GVS identified as gvpC. The compositions, methods and systems described herein can be used with compositions, methods and systems (e.g., gas vesicle compositions and ultrasonic methods) previously described in U.S. Patent Application Publication Nos. 2014/0288411, 2014/0288421, 2018/0030501, 2018/0038922, 2019/0175763, 2019/0314001, 2020/0164095, 2020/0237346, and International Patent Application Publication WO2020/146379; the content of each of these applications is incorporated herein by reference in its entirety.

In particular, a GV in the sense of the disclosure is a structure intracellularly expressed by bacteria or archaea forming a hollow structure wherein a gas is enclosed by a protein shell, which is a shell substantially made of protein (up at least 95% protein). In gas vesicles in the sense of the disclosure, the protein shell is formed by a plurality of proteins herein also indicated as Gyp proteins or Gvps, which are expressed by the bacteria or archaea and form in the bacteria or archaea cytoplasm a gas permeable and liquid impermeable protein shell configuration encircling gas. Accordingly, a protein shell of a GV is permeable to gas but not to surrounding liquid such as water. For example, GVs' protein shells exclude liquid water but permit gas to freely diffuse in and out from the surrounding media making them physically stable despite their usual nanometer size.

GV structures are typically nanostructures with widths and lengths of nanometer dimensions (in particular with widths of 45-250 nm and lengths of 100-800 nm) but can have lengths as large as the dimensions of a cell in which they are expressed, as will be understood by a skilled person. GVs and methods are described in Farhadi et al, Science, 2019, hereby incorporated by reference. In certain embodiments, the gas vesicles protein structure have average dimensions of 1000 nm or less, such as 900 nm or less, including 800 nm or less, or 700 nm or less, or 600 nm or less, or 500 nm or less, or 400 nm or less, or 300 nm or less, or 250 nm or less, or 200 nm or less, or 150 nm or less, or 100 nm or less, or 75 nm or less, or 50 nm or less. For example, the average diameter of the gas vesicles may range from 10 nm to 1000 nm, such as 25 nm to 500 nm, including 50 nm to 250 nm, or 100 nm to 250 nm. By “average” is meant the arithmetic mean.

GVs in the sense of the disclosure have different shapes depending on their genetic origins. For example, GVs in the sense of the disclosure can be substantially spherical, ellipsoid, cylindrical, or have other shapes such as football shape or cylindrical with cone shaped end portions depending on the type of bacteria providing the gas vesicles.

The term Gas Vesicle Structural (GVS) proteins as used herein indicates proteins forming part of a gas-filled protein structure intracellularly expressed by certain bacteria or archaea and can be used as a mechanism to regulate cellular buoyancy in aqueous environments. In particular, GVS shell comprises a GVS identified as gvpA or gvpB (herein also referred to as Gyp A/B) and optionally also a GVS identified as gvpC. GvpA is a structural protein that assembles through repeated unites to make up the bulk of GVs. GvpC is a scaffold protein with 5 repeat units that assemble on the outer shell of GVs. GvpC can be engineered to tune the mechanical and acoustic properties of GVs as well as act as a handle for appending moieties on to. A gvpC protein is a hydrophilic protein of a GV shell, which includes repetitions of one repeat region flanked by an N-terminal region and a C terminal region. The term “repeat region” or “repeat” as used herein with reference to a protein can refer to the minimum sequence that is present within the protein in multiple repetitions along the protein sequence without any gaps. Accordingly, in a gvpC multiple repetitions of a same repeat is flanked by an N-terminal region and a C-terminal region. In a same gvpC, repetitions of a same repeat in the gvpC protein can have different lengths and different sequence identity one with respect to another.

The optional gvpC gene encodes for a gvpC protein which is a hydrophilic protein of a GV shell, including repetitions of one repeat region flanked by an N-terminal region and a C terminal region. The term “repeat region” or “repeat” as used herein with reference to a protein can refer to the minimum sequence that is present within the protein in multiple repetitions along the protein sequence without any gaps. Accordingly, in a gvpC multiple repetitions of a same repeat is flanked by an N-terminal region and a C-terminal region. In a same gvpC, repetitions of a same repeat in the gvpC protein can have different lengths and different sequence identity one with respect to another. In performing alignment steps sequence are identified as repeat when the sequence shows at least 3 or more of the characteristics described in U.S. application Ser. No. 15/663,635 published as US 2018/0030501 (incorporated herein by reference in its entirety) which also include additional features of gvpC proteins and the related identification.

The phrase “GV type” as used herein shall be given its ordinary meaning, and shall also refer to a gas vesicle having dimensions and shape resulting in distinctive mechanical, acoustic, surface and/or magnetic properties as will be understood by a skilled person upon reading of the present disclosure. In particular, a skilled person will understand that different shapes and dimensions will result in different properties in view of the indications in provided in U.S. application Ser. No. 15/613,104 and U.S. Ser. No. 15/663,600 and additional indications identifiable by a skilled person. In some embodiments, the nucleic acid compositions provided herein encode a combination of different GV types and/or variants thereof, with each expressed GV exhibiting a different acoustic collapse profile with progressively decreased midpoint collapse pressure values. In some embodiments, the percentage difference between the midpoint collapse pressure values of any given two expressed GVs types is at least twenty percent.

In some embodiments, GVs are capable of withstanding pressures of several kPa. but collapse irreversibly at a pressure at which the GV protein shell is deformed to the point where it flattens or breaks, allowing the gas inside the GV to dissolve irreversibly in surrounding media, herein also referred to as a critical collapse pressure, or selectable critical collapse pressure, as there are various points along a collapse pressure profile (e.g., peak acoustic pressure).

A collapse pressure profile (e.g., peak acoustic pressure) as used herein indicates a range of pressures over which collapse of a population of GVs of a certain type occurs. In particular, a collapse pressure profile in the sense of the disclosure comprise increasing acoustic collapse pressure values, starting from an initial collapse pressure value at which the GV signal/optical scattering by GVs starts to be erased to a complete collapse pressure value at which the GV signal/optical scattering by GVs is completely erased. The collapse pressure profile of a set type of GV is thus characterized by a mid-point pressure where 50% of the GVs of the set type have been collapsed (also known as the “midpoint collapse pressure”), an initial collapse pressure where 5% or lower of the GVs of the type have been collapsed, and a complete collapse pressure where at least 95% of the GVs of the type have been collapsed. In some embodiments herein described a selectable critical collapse pressure can be any of these collapse pressures within a collapse pressure profile, as well as any point between them. The critical collapse pressure profile of a GV is functional to the mechanical properties of the protein shell and the diameter of the shell structure. U.S. Patent Application Publication No. 2020/0164095 describes gas vesicles, protein variants and related compositions methods and systems for singleplexed and/or multiplexed ultrasonic methods (e.g., imaging of a target site in which a gas vesicle provides contrast for the imaging) which is modifiable by application of a selectable acoustic collapse pressure value of the gas vesicle, the content of which is hereby expressly incorporated by reference in its entirety.

The acoustic collapse pressure profile (e.g., peak acoustic pressure) of a given GV type can be determined by imaging GVs with imaging ultrasound energy after collapsing portions of the given GV type population with a collapsing ultrasound energy (e.g. ultrasound pulses) with increasing peak positive pressure amplitudes to obtain acoustic pressure data point of acoustic pressure values, the data points forming an acoustic collapse curve. The acoustic collapse pressure function f(p) can be derived from the acoustic collapse curve by fitting the data with a sigmoid function such as a Boltzmann sigmoid function. An acoustic collapse pressure profile in the sense of the disclosure can include a set of initial collapse pressure values, a midpoint collapse pressure value and a set of complete collapse pressure values. The initial collapse pressures are the acoustic collapse pressures at which 5% or less of the GV signal is erased. A midpoint collapse pressure is the acoustic collapse pressure at which 50% of the GV signal is erased. Complete collapse pressures are the acoustic collapse pressures at which 95% or more of the GV signal is erased. The pressure can be peak pressure. In some embodiments, the peak pressure is peak positive pressure. In some embodiments, the peak pressure is peak negative pressure.

One or more of the first unit payload protein(s), the second unit payload protein(s), and/or the supplemental unit payload protein(s) can be encoded by gas vesicle assembly (GVA) genes and/or gas vesicle structural (GVS) genes, such as, for example, GVA genes and/or GVS genes from Bacillus Megaterium, Anabaena flos-aquae, Serratia sp., Bukholderia thailandensis, B. megaterium, Frankia sp, Haloferax mediaterranei, Halobacterium sp, Halorubrum vacuolatum, Microcystis aeruginosa, Methanosarcina barkeri, Streptomyces coelicolor, and/or Psychromonas ingrahamii.

The polynucleotide and/or second polynucleotide comprises: two or more GVS genes derived from different prokaryotic species; GVA genes and/or GVS genes from Bacillus Megaterium, Anabaena flos-aquae, Serratia sp., Bukholderia thailandensis, B. megaterium, Frankia sp, Haloferax mediaterranei, Halobacterium sp, Microchaete diplosiphon, Nostoc sp, Halorubrum vacuolatum, Microcystis aeruginosa, Methanosarcina barkeri, Streptomyces coelicolor, and/or Psychromonas ingrahamii; gvpB, gvpN gvpF, gvpG, gvpL gvpS, gvpK, gvpJ, and/or gvpU from B. megaterium; gvpA, gvpC, gvpN, gvpJ, gvpK, gvpF, gvpG, gvpV, and/or gvpW from Anabaena flos-aquae; gvpR, gvpN, gvpF, gvpG, gvpL, gvpS, gvpK, gvpJ, gvpT and/or gvpU from B. megaterium and gvpA from Anabaena flos-aquae; gvpA, and/or gvpC from Anabaena flos-aquae, and gvpN, gvpF, gvpG, gvpL, gvpS, gvpK, gvpJ, and/or gvpU from B. megaterium; and/or gvpA, gvpC and/or gvpN from Anabaena flos-aquae, and gvpF, gvpG, gvpL, gvpS, gvpK, gvpJ, and/or gvpU from B. megaterium.

U.S. Patent Application Publication No. 2018/0030501 describes hybrid gas vesicle gene cluster (GVGC) configured for expression in a prokaryotic host comprising gas vesicle assembly (GVA) genes native to a GVA prokaryotic species and capable of being expressed in a functional form in the prokaryotic host, as well as one or more gas vesicle structural (GVS) genes native to one or more GVS prokaryotic species, at least one of the one or more GVS prokaryotic species different from the GVA prokaryotic species, and related gas vesicle reporting (GVR) genetic circuits, genetic, vectors, engineered cells, and related compositions methods and systems to produce GVs, hybrid GVGC and/or image a target site, the content of which is hereby expressly incorporated by reference in its entirety. The term “Gas Vesicle Genes Cluster” or “GVGC” as described herein indicates a gene cluster encoding a set of GV proteins capable of providing a GV upon expression within a cell. In some embodiments, the nucleic acid compositions provided herein encode some or all elements of a GVGC. The term “gene cluster” as used herein means a group of two or more genes found within an organism's DNA that encode two or more polypeptides or proteins, which collectively share a generalized function or are genetically regulated together to produce a cellular structure and are often located within a few thousand base pairs of each other. The size of gene clusters can vary significantly, from a few genes to several hundred genes. Portions of the DNA sequence of each gene within a gene cluster are sometimes found to be similar or identical; however, the resulting protein of each gene is distinctive from the resulting protein of another gene within the cluster. Genes found in a gene cluster can be observed near one another on the same chromosome or native plasmid DNA, or on different, but homologous chromosomes. An example of a gene cluster is the Hox gene, which is made up of eight genes and is part of the Homeobox gene family. In the sense of the disclosure, gene clusters as described herein also comprise gas vesicle gene clusters, wherein the expressed proteins thereof together are able to form gas vesicles.

Engineered GVs and methods of tuning the acoustic properties thereof are provided in U.S. Patent Application Publication No. 2020/0164095, the content of which is incorporated herein by reference in its entirety. In some embodiments, the GVs can be engineered to modulate the GV mechanical, acoustic, surface and targeting properties in order to achieve enhanced harmonic responses and multiplexed imaging to be better distinguished from background tissues. In some embodiments herein described Gas vesicles protein structures can be provided by Gyp genes endogenously expressed in bacteria or archaea. Endogenous expression can refer to expression of Gyp proteins forming the protein shell of the GV in bacteria or archaea that naturally produce gas vesicles encoded (e.g. in their genome or native plasmid DNA). Gyp proteins expressed by bacteria or archaea typically include two primary structural proteins, here also indicated as GvpA and GvpC, and several putative minor components and chaperones as would be understood by a person skilled in the art. In some embodiments, heterologously expressed Gyp proteins to provide a GV type have independently at least 50% sequence identity, preferably at least 80%, more preferably at least 90%, most preferably at least 95% sequence identity compared to a reference sequence of corresponding Gyp protein using one of the alignment programs described using standard parameters.

In some embodiments, the GVA genes and GVS genes have sequences codon optimized for expression in a eukaryotic cell. The gas vesicle(s) can comprise a GVS variant engineered to present a tag enabling clustering in the cell. The gas vesicle(s) can comprise a GvpC variant comprising at least one protease recognition site inserted within the central portion and/or attached to at least one of the N-terminus and the C-terminus of the Gyp. One or more of the mechanical, acoustic, surface and/or magnetic properties of the gas vesicle(s) can be capable of being configured by adjusting the eTIS of one or more of the first nucleic acid unit, the second nucleic acid unit, the n supplemental nucleic acid unit(s), and/or the secondary nucleic acid units. The gas vesicle(s) can be hybrid gas vesicle(s) derived from two or more prokaryotic species.

The plurality of gas vesicles can comprise a first collapse pressure profile. The first collapse pressure profile can comprise a collapse function from which a gas vesicle collapse amount can be determined for a given pressure value. In some embodiments, the first collapse pressure profile comprises a first initial collapse pressure where 5% or lower of the plurality of gas vesicles are collapsed, a first midpoint collapse pressure where 50% of the plurality of gas vesicles are collapsed, a first complete collapse pressure where at least 95% of the plurality of gas vesicles are collapsed, any pressure between the first initial collapse pressure and the first midpoint collapse pressure, and any pressure between the first midpoint collapse pressure and the first complete collapse pressure. In some embodiments, a first selectable collapse pressure is: any collapse pressure within the first collapse pressure profile; selected from the first collapse pressure profile at a value between 0.05% collapse of the plurality of gas vesicles and 95% collapse of the plurality of gas vesicles; equal to or greater than the first initial collapse pressure; equal to or greater than the first midpoint collapse pressure; and/or equal to or greater than the first complete collapse pressure.

The plurality of secondary gas vesicles can comprise a second collapse pressure profile. The second collapse pressure profile can comprise a collapse function from which a secondary gas vesicle collapse amount can be determined for a given pressure value. The first collapse pressure profile and the second collapse pressure profile can be different. In some embodiments, the first collapse pressure profile and/or second collapse pressure profile has been configured by engineering a gas vesicle protein C (GvpC) protein of the gas vesicles and/or the secondary gas vesicles. In some embodiments, a midpoint of the second collapse profile has a higher pressure component than a midpoint of the first collapse profile. In some embodiments, the second collapse pressure profile comprises a second initial collapse pressure where 5% or lower of the plurality of secondary gas vesicles are collapsed, a second midpoint collapse pressure where 50% of the plurality of secondary gas vesicles are collapsed, a second complete collapse pressure where at least 95% of the plurality of secondary gas vesicles are collapsed, any pressure between the second initial collapse pressure and the second midpoint collapse pressure, and any pressure between the second midpoint collapse pressure and the second complete collapse pressure. In some embodiments, a second selectable collapse pressure is: any collapse pressure within the second collapse pressure profile; selected from the second collapse pressure profile at a value between 0.05% collapse of the plurality of secondary gas vesicles and 95% collapse of the plurality of secondary gas vesicles; equal to or greater than the second initial collapse pressure; equal to or greater than the second midpoint collapse pressure; and/or equal to or greater than the second complete collapse pressure

Methods of Imaging and Treatment

There are provided, in some embodiments, methods of imaging a target site of a subject. In some embodiments, the method comprises: administering to the subject an effective amount of a nucleic acid composition disclosed herein, a pharmaceutical composition disclosed herein, or engineered cells disclosed herein. In some embodiments, the method comprises: applying a magnetic field and/or ultrasound (US) to a target site of a subject to obtain an MRI and/or US image of the target site. The period of time between the administering and applying can be about 14 days, about 7 days, about 3 days, about 48 hours, about 44 hours, about 40 hours, about 35 hours, about 30 hours, about 25 hours, 20 hours, 15 hours, 10 hours, about 8 hours, about 8 hours, 8 hours, about 7 hours, about 6 hours, about 5 hours, about 4 hours, about 3 hours, about 2 hours, about 1 hour, about 30 minutes, about 15 minutes, about 10 minutes, or about 5 minutes.

The basic physics of sound waves enables ultrasound to visualize biological tissues with high spatial and temporal resolution. This capability has been enhanced by the development of acoustic biomolecules proteins with physical properties enabling them to scatter sound. The first acoustic biomolecules developed as contrast agents in ultrasound imaging, analogous to GFPs used in optical imaging, were based on a unique class of air-filled protein nanostructures called gas vesicles (GVs). The advancement of GVs has made it possible to use ultrasound to visualize the functions of cells deep inside tissues.

The term “ultrasound” can refer to sound with frequencies higher than the audible limits of human beings, typically over 20 kHz. Ultrasound devices typically can range up to the gigahertz range of frequencies, with most medical ultrasound devices operating in the 0.2 to 18 MHz range. The amplitude of the waves relates to the intensity of the ultrasound, which in turn relates to the pressure created by the ultrasound waves. Applying ultrasound can be accomplished, for example, by sending strong, short electrical pulses to a piezoelectric transducer directed at the target. Ultrasound can be applied as a continuous wave, or as wave pulses as will be understood by a person skilled in focused ultrasound. U.S. Patent Application Publication No. 2020/0237346 describes methods comprising the application of a step function increase in acoustic pressure during ultrasound imaging using gas vesicle contrast, along with capturing successive frames of ultrasound imaging and extracting time-series vectors for pixels of the frames, the content of which is hereby expressly incorporated by reference in its entirety. In some embodiments, the first, second, third, fourth, fifth, and/or sixth US pulse(s) each comprise a set of pulses.

Focused ultrasound (“FUS”) can refer to the technology that uses ultrasound energy to target specific areas of a subject, such as a specific area of a brain or body. FUS focuses acoustic waves by employing concave transducers that usually have a single geometric focus, or an array of ultrasound transducer elements which are actuated in a spatiotemporal pattern such as to produce one or more focal zones. At this focus or foci most of the power is delivered during sonication in order to induce mechanical effects, thermal effects, or both. The frequencies used for focused ultrasound are in the range of 200 KHz to 8000 KHz.

As used herein, the term “harmonic signal” or “harmonic frequency” can refer to a frequency in a periodic waveform that is an integer multiple of the frequency of the fundamental signal. In addition, this term encompasses sub-harmonic signals, which are signals with a frequency equal to an integral submultiple of the frequency of the fundamental signal. In ultrasound imaging, the transmitted pulse is typically centered around a fundamental frequency, and received signals may be processed to isolate signals centered around the fundamental frequency or one or more harmonic frequencies.

The term “fundamental signal” or “fundamental wave” can refer to the primary frequency of the transmitted ultrasound pulse. All GVs can backscatter ultrasound at the fundamental frequency, allowing their detection by ultrasound.

The term “non-linear signal” can refer to a signal that does not obey superposition and scaling properties, with regards to the input. The term “linear signal” can refer to a signal that does obey those properties. One example of non-linearity is the production of harmonic signals in response to ultrasound excitation at a certain fundamental frequency. Another example is a non-linear response to acoustic pressure. One embodiment of such a non-linearity is the acoustic collapse profile of GVs, in which there is a non-linear relationship between the applied pressure and the disappearance of subsequent ultrasound contrast from the GVs as they collapse. Another example of a non-linear signal that does not involve the destruction of GVs, is the increase in both fundamental and harmonic signals with increasing pressure of the transmitted imaging pulse, wherein certain GVs exhibit a super-linear relationship between these signals and the pulse pressure.

The term “applying ultrasound” shall be given its ordinary meaning, and shall also refer to sending ultrasound-range acoustic energy to a target. The sound energy produced by the piezoelectric transducer can be focused by beamforming, through transducer shape, lensing, or use of control pulses. The soundwave formed is transmitted to the body, then partially reflected or scattered by structures within a body; larger structures typically reflecting, and smaller structures typically scattering. The return sound energy reflected/scattered to the transducer vibrates the transducer and turns the return sound energy into electrical signals to be analyzed for imaging. The frequency and pressure of the input sound energy can be controlled and are selected based on the needs of the particular imaging/delivery task and, in some methods described herein, collapsing GVs (thereby inducing engineered cells herein to release payload molecules at a target site). To create images, particularly 2D and 3D imaging, scanning techniques can be used where the ultrasound energy is applied in lines or slices which are composited into an image.

The nucleic acid composition can be capable of expressing gas vesicle(s) having an acoustic collapse pressure threshold, and wherein applying ultrasound comprises: applying ultrasound to the target site at a peak positive pressure less than the acoustic collapse pressure threshold; increasing peak positive pressure (PPP) to above the selective acoustic collapse pressure value as a step function; and imaging the target site in successive frames during the increasing; and extracting a time-series vector for each of at least one pixel of the successive frames. In some embodiments, the method comprises: performing a signal separation algorithm on the time-series vectors using at least one template vector. In some embodiments, the signal separation algorithm includes template projection and/or template unmixing. In some embodiments, the at least one template vector includes linear scatterers, noise, gas vesicles, or a combination thereof. The successive frames can comprise a frame prior to GVs collapse, a frame during GVs collapse, and a frame after GVs collapse. In some embodiments, the increasing includes increasing the PPP to a hiBURST regime, optionally the PPP in hiBURST regime is 4.3 MPa or higher. In some embodiments, the increasing includes increasing the PPP to a loBURST regime, optionally the PPP in loBURST regime is no higher than 3.7 MPa

In some embodiments, applying US to a target site can comprise applying one or more US pulses to the target site over a duration of time. The duration of time can be about 48 hours, about 44 hours, about 40 hours, about 35 hours, about 30 hours, about 25 hours, 20 hours, 15 hours, 10 hours, about 8 hours, about 8 hours, 8 hours, about 7 hours, about 6 hours, about 5 hours, about 4 hours, about 3 hours, about 2 hours, about 1 hour, about 30 minutes, about 15 minutes, about 10 minutes, or about 5 minutes. In some embodiments, the one or more US pulses each have a pulse duration of about 1 hour, about 30 minutes, about 15 minutes, about 10 minutes, about 5 minutes, about 1 minute, about 1 second, or about 1 millisecond. Applying an US pulse can comprise applying a focused US pulse. Applying an US pulse can comprise applying US at a frequency of 100 kHz to 100 MHz. Applying an US pulse can comprise applying ultrasound at a frequency of 0.2 to 1.5 mHz. Applying an US pulse can comprise applying ultrasound having a mechanical index in a range between 0.2 and 0.6. The US pulse can comprise a peak pressure of about 40 kPa to about 800 kPa. The US pulse can comprise a peak pressure of about 70 kPa to about 150 kPa, and/or about 440 kPa to about 605 kPa.

There are provided, in some embodiments, methods of treating or preventing a disease or disorder in a subject. In some embodiments, the method comprises: administering to the subject an effective amount of a nucleic acid composition disclosed herein, a pharmaceutical composition disclosed herein, or engineered cells disclosed herein. In some embodiments, the method comprises the spatial and temporal delivery of payload molecules to a target site of a subject, the method comprising: applying a first ultrasonic (US) pulse to a target site of the subject; detecting the presence of the engineered cells; and applying a second US pulse to the target site of the subject, wherein the second US pulse induces the release of payload molecules from the engineered cells, thereby delivering payload molecules to the target site. The payload molecules can comprise the first unit payload protein(s), the second unit payload protein(s), and/or the supplemental unit payload protein(s).

In some embodiments, multiplexed imaging and payload delivery methods are provided. The term “multiplex” can refer to the presence of two or more distinct GVPS types, each of which exhibits an acoustic collapse pressure profile distinct from one another, in the engineered cells. The two or more distinct GVPSs can be derived from different organisms or variants of GVPSs from the same or different organisms (e.g., archaea).

In multiplexing methods herein described, both the collapsing pressure of the collapsing ultrasound and the imaging pressure of the imaging ultrasound are selected based on the acoustic collapse pressure profiles of the GVPS types (e.g., peak acoustic pressure) to selectively collapse one GVPS type over the other GVPS types. The term “selectively collapse” can refer to collapsing at least a portion of one GVPS type in a greater amount that any other GVPS type in a mixture containing a plurality of GVPS types.

In certain embodiments, the method includes applying a set of imaging pulses from an ultrasound transmitter to the target site, and receiving ultrasound signal at a receiver. In certain instances, the ultrasound signal detected by the receiver includes an ultrasound echo signal. Additional information of ultrasound systems and methods can be found in related publications as will be understood by a person skilled in the art.

Methods for performing ultrasound imaging are known in the art and can be employed in methods of the current disclosure. In certain aspects, an ultrasound transducer, which comprises piezoelectric elements, transmits an ultrasound imaging signal (or pulse) in the direction of the target site. Variations in the acoustic impedance (or echogenicity) along the path of the ultrasound imaging signal causes backscatter (or echo) of the imaging signal, which is received by the piezoelectric elements. The received echo signal is digitized into ultrasound data and displayed as an ultrasound image. Conventional ultrasound imaging systems comprise an array of ultrasonic transducer elements that are used to transmit an ultrasound beam, or a composite of ultrasonic imaging signals that form a scan line. The ultrasound beam is focused onto a target site by adjusting the relative phase and amplitudes of the imaging signals. The imaging signals are reflected back from the target site and received at the transducer elements. The voltages produced at the receiving transducer elements are summed so that the net signal is indicative of the ultrasound energy reflected from a single focal point in the subject. An ultrasound image is then composed of multiple image scan lines.

In some embodiments, imaging the target site is performed by applying or transmitting an imaging ultrasound signal from an ultrasound transmitter to the target site and receiving a set of ultrasound data at a receiver. The ultrasound data can be obtained using a standard ultrasound device, or can be obtained using an ultrasound device configured to specifically detect the contrast agent used. Obtaining the ultrasound data can include detecting the ultrasound signal with an ultrasound detector. In some embodiments, the imaging step further comprises analyzing the set of ultrasound data to produce an ultrasound image.

In certain embodiments, the ultrasound signal has a transmit frequency of at least 1 MHz, 5 MHz, 10 MHz, 20 MHz, 30 MHz, 40 MHz or 50 MHz. For example, an ultrasound data is obtained by applying to the target site an ultrasound signal at a transmit frequency from 4 to 11 MHz, or at a transmit frequency from 14 to 22 MHz. In some instances, the imaging frequency is selected so as to maximize the contrast generated by the administered contrast agent.

In the embodiments herein described, the collapsing ultrasound and imaging ultrasound are selected to have a collapsing pressure and an imaging pressure amplitude based on the acoustic collapse pressure profile (e.g., peak acoustic pressure) of the GVPS type used. In some instances, the ultrasound pressure, including the collapsing ultrasound pressure and the imaging ultrasound pressure can be referred to as the “peak positive pressure” of the ultrasound pulses. The term “peak positive pressure” can refer to the maximum pressure amplitude of the positive pulse of a pressure wave, typically in terms of the difference between the peak pressure and the ambient pressure at the location in the person or specimen that is being imaged.

In some embodiments, detecting the presence of the engineered cells at the target site can comprise detecting scattering of the first US pulse by the gas vesicles. In some embodiments, the method comprises: confirming the delivery of payload molecules at the target site. In some embodiments, confirming the delivery of payload molecules can comprise detecting reduced scattering of the second US pulse by the gas vesicles. The gas vesicles can be capable of acting as a contrast agent at the first US pulse but not at the second US pulse. The first US pulse can comprise a pressure value less than the first selectable collapse pressure value. The second US pulse can comprise a pressure value equal to or higher than the first selectable collapse pressure value. In some embodiments, the second US pulse induces gas vesicle collapse. The gas vesicles can be capable of acting as a contrast agent at the first US pulse but not at the second US pulse.

In some embodiments, the gas vesicle collapse results in the release of a nanoscale air bubble. In some embodiments, the released nanoscale air bubble undergoes cavitation and is converted into a micron-scale air bubble. The second US pulse can be capable of inducing cavitation.

The methods that can be used to improve the transcription and/or translation of a gene herein are not particularly limited. For example, the nucleotide sequence can be modified to better reflect host codon usage to increase gene expression (e.g., protein production) in the host (e.g., a mammal).

The degree of payload protein(s) (e.g., first unit payload protein(s), second unit payload protein(s), supplemental unit payload protein(s), secondary unit payload protein(s)) expression in the cell can vary.

Chimeric Antigen Receptors and Engineered T Cell Receptors

Unit payload protein(s) (e.g., first unit payload protein(s), second unit payload protein(s), supplemental unit payload protein(s), secondary unit payload protein(s)) can comprise a chimeric antigen receptor (CAR) or T-cell receptor (TCR). In some embodiments, the CAR comprises a T-cell receptor (TCR) antigen binding domain. The term “Chimeric Antigen Receptor” or alternatively a “CAR” refers to a set of polypeptides, typically two in the simplest embodiments, which when in an immune effector cell, provides the cell with specificity for a target cell, typically a cancer cell, and with intracellular signal generation. The terms “CAR” and “CAR molecule” are used interchangeably. In some embodiments, a CAR comprises at least an extracellular antigen binding domain, a transmembrane domain and a cytoplasmic signaling domain (also referred to herein as “an intracellular signaling domain”) comprising a functional signaling domain derived from a stimulatory molecule and/or costimulatory molecule as defined below. In some embodiments, the set of polypeptides are in the same polypeptide chain (e.g., comprise a chimeric fusion protein). In some aspects, the set of polypeptides are contiguous with each other. In some embodiments, the set of polypeptides are not contiguous with each other, e.g., are in different polypeptide chains. In some embodiments, the set of polypeptides include a dimerization switch that, upon the presence of a dimerization molecule, can couple the polypeptides to one another, e.g., can couple an antigen binding domain to an intracellular signaling domain. In one aspect, the stimulatory molecule is the zeta chain associated with the T cell receptor complex. In one aspect, the cytoplasmic signaling domain further comprises one or more functional signaling domains derived from at least one costimulatory molecule as defined below. In some embodiments, the costimulatory molecule is chosen from the costimulatory molecules described herein, e.g., 4-1BB (i.e., CD137), CD27 and/or CD28. In some embodiments, the CAR comprises a chimeric fusion protein comprising an extracellular antigen binding domain, a transmembrane domain and an intracellular signaling domain comprising a functional signaling domain derived from a stimulatory molecule. In some embodiments, the CAR comprises a chimeric fusion protein comprising an extracellular antigen binding domain, a transmembrane domain and an intracellular signaling domain comprising a functional signaling domain derived from a costimulatory molecule and a functional signaling domain derived from a stimulatory molecule. In some embodiments, the CAR comprises a chimeric fusion protein comprising an extracellular antigen binding domain, a transmembrane domain and an intracellular signaling domain comprising two functional signaling domains derived from one or more costimulatory molecule(s) and a functional signaling domain derived from a stimulatory molecule. In some embodiments, the CAR comprises a chimeric fusion protein comprising an extracellular antigen binding domain, a transmembrane domain and an intracellular signaling domain comprising at least two functional signaling domains derived from one or more costimulatory molecule(s) and a functional signaling domain derived from a stimulatory molecule. In some embodiments the CAR comprises an optional leader sequence at the amino-terminus (N-ter) of the CAR fusion protein. In some embodiments, the CAR further comprises a leader sequence at the N-terminus of the extracellular antigen binding domain, wherein the leader sequence is optionally cleaved from the antigen binding domain (e.g., a scFv) during cellular processing and localization of the CAR to the cellular membrane.

The CAR and/or TCR can comprise one or more of an antigen binding domain, a transmembrane domain, and an intracellular signaling domain. The CAR or TCR further can comprise a leader peptide. The TCR further can comprise a constant region and/or CDR4. The term “signaling domain” refers to the functional portion of a protein which acts by transmitting information within the cell to regulate cellular activity via defined signaling pathways by generating second messengers or functioning as effectors by responding to such messengers. An “intracellular signaling domain,” as used herein, refers to an intracellular portion of a molecule. The intracellular signaling domain generates a signal that promotes an immune effector function of the CAR containing cell, e.g., a CART cell. Examples of immune effector function, e.g., in a CART cell, include cytolytic activity and helper activity, including the secretion of cytokines. The intracellular signaling domain can comprise a primary intracellular signaling domain. Exemplary primary intracellular signaling domains include those derived from the molecules responsible for primary stimulation, or antigen dependent simulation. In an embodiment, the intracellular signaling domain can comprise a costimulatory intracellular domain. Exemplary costimulatory intracellular signaling domains include those derived from molecules responsible for costimulatory signals, or antigen independent stimulation. For example, in the case of a CART, a primary intracellular signaling domain can comprise a cytoplasmic sequence of a T cell receptor, and a costimulatory intracellular signaling domain can comprise cytoplasmic sequence from co-receptor or costimulatory molecule. A primary intracellular signaling domain can comprise a signaling motif which is known as an immunoreceptor tyrosine-based activation motif or ITAM. Examples of ITAM containing primary cytoplasmic signaling sequences include, but are not limited to, those derived from CD3 zeta, common FcR gamma (FCER1G), Fc gamma RIIa, FcR beta (Fc Epsilon Rib), CD3 gamma, CD3 delta, CD3 epsilon, CD79a, CD79b, DAP10, and DAP12.

The intracellular signaling domain can comprise a primary signaling domain, a costimulatory domain, or both of a primary signaling domain and a costimulatory domain. The cytoplasmic domain or region of the CAR includes an intracellular signaling domain. An intracellular signaling domain is generally responsible for activation of at least one of the normal effector functions of the immune cell in which the CAR has been introduced. The term “effector function” refers to a specialized function of a cell. Effector function of a T cell, for example, may be cytolytic activity or helper activity including the secretion of cytokines. Thus the term “intracellular signaling domain” refers to the portion of a protein which transduces the effector function signal and directs the cell to perform a specialized function. While usually the entire intracellular signaling domain can be employed, in many cases it is not necessary to use the entire chain. To the extent that a truncated portion of the intracellular signaling domain is used, such truncated portion may be used in place of the intact chain as long as it transduces the effector function signal. The term intracellular signaling domain is thus meant to include any truncated portion of the intracellular signaling domain sufficient to transduce the effector function signal.

The term “costimulatory molecule” refers to a cognate binding partner on a T cell that specifically binds with a costimulatory ligand, thereby mediating a costimulatory response by the T cell, such as, but not limited to, proliferation. Costimulatory molecules are cell surface molecules other than antigen receptors or their ligands that are contribute to an efficient immune response. Costimulatory molecules include, but are not limited to, an MHC class I molecule, BTLA and a Toll ligand receptor, as well as OX40, CD27, CD28, CD5, ICAM-1, LFA-1 (CD11a/CD18), ICOS (CD278), and 4-1BB (CD137). Further examples of such costimulatory molecules include CD5, ICAM-1, GITR, BAFFR, HVEM (LIGHTR), SLAMF7, NKp80 (KLRF1), NKp44, NKp30, NKp46, CD160, CD19, CD4, CD8alpha, CD8beta, IL2R beta, IL2R gamma, IL7R alpha, ITGA4, VLA1, CD49a, ITGA4, IA4, CD49D, ITGA6, VLA-6, CD49f, ITGAD, CD11 d, ITGAE, CD103, ITGAL, CD11a, LFA-1, ITGAM, CD11b, ITGAX, CD11c, ITGB1, CD29, ITGB2, CD18, LFA-1, ITGB7, NKG2D, NKG2C, TNFR2, TRANCE/RANKL, DNAM1 (CD226), SLAMF4 (CD244, 2B4), CD84, CD96 (Tactile), CEACAM1, CRTAM, Ly9 (CD229), CD160 (BY55), PSGL1, CD100 (SEMA4D), CD69, SLAMF6 (NTB-A, Ly108), SLAM (SLAMF1, CD150, IPO-3), BLAME (SLAMF8), SELPLG (CD162), LTBR, LAT, GADS, SLP-76, PAG/Cbp, CD19a, and a ligand that specifically binds with CD83. A costimulatory intracellular signaling domain can be the intracellular portion of a costimulatory molecule. A costimulatory molecule can be represented in the following protein families: TNF receptor proteins, Immunoglobulin-like proteins, cytokine receptors, integrins, signaling lymphocytic activation molecules (SLAM proteins), and activating NK cell receptors. The intracellular signaling domain can comprise the entire intracellular portion, or the entire native intracellular signaling domain, of the molecule from which it is derived, or a functional fragment or derivative thereof.

Examples of intracellular signaling domains for use in the CAR of the invention include the cytoplasmic sequences of the T cell receptor (TCR) and co-receptors that act in concert to initiate signal transduction following antigen receptor engagement, as well as any derivative or variant of these sequences and any recombinant sequence that has the same functional capability. It is known that signals generated through the TCR alone are insufficient for full activation of the T cell and that a secondary and/or costimulatory signal is also required. Thus, T cell activation can be said to be mediated by two distinct classes of cytoplasmic signaling sequences: those that initiate antigen-dependent primary activation through the TCR (primary intracellular signaling domains) and those that act in an antigen-independent manner to provide a secondary or costimulatory signal (secondary cytoplasmic domain, e.g., a costimulatory domain). A primary signaling domain regulates primary activation of the TCR complex either in a stimulatory way, or in an inhibitory way. Primary intracellular signaling domains that act in a stimulatory manner may contain signaling motifs which are known as immunoreceptor tyrosine-based activation motifs or ITAMs. The primary signaling domain can comprise a functional signaling domain of one or more proteins selected from the group consisting of CD3 zeta, CD3 gamma, CD3 delta, CD3 epsilon, common FcR gamma (FCERIG), FcR beta (Fc Epsilon Rib), CD79a, CD79b, Fcgamma RIIa, DAP10, and DAP12, or a functional variant thereof.

The intracellular signaling domain can be designed to comprise two or more, e.g., 2, 3, 4, 5, or more, costimulatory signaling domains. In some embodiments, the two or more, e.g., 2, 3, 4, 5, or more, costimulatory signaling domains, are separated by a linker molecule, e.g., a linker molecule described herein. In some embodiments, the intracellular signaling domain comprises two costimulatory signaling domains. In some embodiments, the linker molecule is a glycine residue. In some embodiments, the linker is an alanine residue. The costimulatory domain can comprise a functional domain of one or more proteins selected from the group consisting of CD27, CD28, 4-1BB (CD137), OX40, CD28-OX40, CD28-4-1BB, CD30, CD40, PD-1, ICOS, lymphocyte function-associated antigen-1 (LFA-1), CD2, CD7, LIGHT, NKG2C, B7-H3, a ligand that specifically binds with CD83, CD5, ICAM-1, GITR, BAFFR, HVEM (LIGHTR), SLAMF7, NKp80 (KLRF1), CD160, CD19, CD4, CD8alpha, CD8beta, IL2R beta, IL2R gamma, IL7R alpha, ITGA4, VLA1, CD49a, ITGA4, IA4, CD49D, ITGA6, VLA-6, CD49f, ITGAD, CD11d, ITGAE, CD103, ITGAL, CD11a, LFA-1, ITGAM, CD11b, ITGAX, CD11c, ITGB1, CD29, ITGB2, CD18, LFA-1, ITGB7, TNFR2, TRANCE/RANKL, DNAM1 (CD226), SLAMF4 (CD244, 2B4), CD84, CD96 (Tactile), CEACAM1, CRTAM, Ly9 (CD229), CD160 (BY55), PSGL1, CD100 (SEMA4D), CD69, SLAMF6 (NTB-A, Ly108), SLAM (SLAMF1, CD150, IPO-3), BLAME (SLAMF8), SELPLG (CD162), LTBR, LAT, GADS, SLP-76, PAG/Cbp, NKp44, NKp30, NKp46, and NKG2D, or a functional variant thereof.

The portion of the CAR comprising an antibody or antibody fragment thereof may exist in a variety of forms where the antigen binding domain is expressed as part of a contiguous polypeptide chain including, for example, a single domain antibody fragment (sdAb), a single chain antibody (scFv), a humanized antibody, or bispecific antibody (Harlow et al., 1999, In: Using Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory Press, NY; Harlow et al., 1989, In: Antibodies: A Laboratory Manual, Cold Spring Harbor, N.Y.; Houston et al., 1988, Proc. Natl. Acad. Sci. USA 85:5879-5883; Bird et al., 1988, Science 242:423-426). In some embodiments, the antigen binding domain of a CAR composition of the invention comprises an antibody fragment. In a further aspect, the CAR comprises an antibody fragment that comprises a scFv.

The CAR can comprise a target-specific binding element otherwise referred to as an antigen binding domain. The choice of moiety depends upon the type and number of ligands that define the surface of a target cell. For example, the antigen binding domain may be chosen to recognize a ligand that acts as a cell surface marker on target cells associated with a particular disease state. Thus, examples of cell surface markers that may act as ligands for the antigen binding domain in a CAR of the invention include those associated with viral, bacterial and parasitic infections, autoimmune disease and cancer cells.

In some embodiments, the CAR-mediated T-cell response can be directed to an antigen of interest by way of engineering an antigen binding domain that specifically binds a desired antigen into the CAR. In some embodiments, the portion of the CAR comprising the antigen binding domain comprises an antigen binding domain that targets a tumor antigen, e.g., a tumor antigen described herein. The antigen binding domain can be any domain that binds to the antigen including but not limited to a monoclonal antibody, a polyclonal antibody, a recombinant antibody, a human antibody, a humanized antibody, and a functional fragment thereof, including but not limited to a single-domain antibody such as a heavy chain variable domain (VH), a light chain variable domain (VL) and a variable domain (VHH) of camelid derived nanobody, and to an alternative scaffold known in the art to function as antigen binding domain, such as a recombinant fibronectin domain, a T cell receptor (TCR), or a fragment there of, e.g., single chain TCR, and the like. In some instances, it is beneficial for the antigen binding domain to be derived from the same species in which the CAR will ultimately be used in. For example, for use in humans, it may be beneficial for the antigen binding domain of the CAR to comprise human or humanized residues for the antigen binding domain of an antibody or antibody fragment. In some embodiments, the antigen binding domain comprises a humanized antibody or an antibody fragment. In some aspects, a non-human antibody is humanized, where specific sequences or regions of the antibody are modified to increase similarity to an antibody naturally produced in a human or fragment thereof. In some embodiments, the antigen binding domain is humanized.

The antigen binding domain can comprise an antibody, an antibody fragment, an scFv, a Fv, a Fab, a (Fab′)2, a single domain antibody (SDAB), a VH or VL domain, a camelid VHH domain, a Fab, a Fab′, a F(ab′)2, a Fv, a scFv, a dsFv, a diabody, a triabody, a tetrabody, a multispecific antibody formed from antibody fragments, a single-domain antibody (sdAb), a single chain comprising cantiomplementary scFvs (tandem scFvs) or bispecific tandem scFvs, an Fv construct, a disulfide-linked Fv, a dual variable domain immunoglobulin (DVD-Ig) binding protein or a nanobody, an aptamer, an affibody, an affilin, an affitin, an affimer, an alphabody, an anticalin, an avimer, a DARPin, a Fynomer, a Kunitz domain peptide, a monobody, or any combination thereof.

The antigen binding domain can be a T cell receptor (“TCR”), or a fragment thereof, for example, a single chain TCR (scTCR). Methods to make such TCRs are known in the art. See, e.g., Willemsen R A et al, Gene Therapy 7: 1369-1377 (2000); Zhang T et al, Cancer Gene Ther 11: 487-496 (2004); Aggen et al, Gene Ther. 19(4):365-74 (2012) (references are incorporated herein by its entirety). For example, scTCR can be engineered that contains the Va and Vp genes from a T cell clone linked by a linker (e.g., a flexible peptide). This approach is very useful to cancer associated target that itself is intracellular, however, a fragment of such antigen (peptide) is presented on the surface of the cancer cells by MHC.

In some embodiments, the antigen binding domain is a multispecific antibody molecule. In some embodiments, the multispecific antibody molecule is a bispecific antibody molecule. A bispecific antibody has specificity for no more than two antigens. A bispecific antibody molecule is characterized by a first immunoglobulin variable domain sequence which has binding specificity for a first epitope and a second immunoglobulin variable domain sequence that has binding specificity for a second epitope. In an embodiment the first and second epitopes are on the same antigen, e.g., the same protein (or subunit of a multimeric protein). In an embodiment the first and second epitopes overlap. In an embodiment the first and second epitopes do not overlap. In an embodiment the first and second epitopes are on different antigens, e.g., different proteins (or different subunits of a multimeric protein). In an embodiment a bispecific antibody molecule comprises a heavy chain variable domain sequence and a light chain variable domain sequence which have binding specificity for a first epitope and a heavy chain variable domain sequence and a light chain variable domain sequence which have binding specificity for a second epitope. In an embodiment a bispecific antibody molecule comprises a half antibody having binding specificity for a first epitope and a half antibody having binding specificity for a second epitope. In an embodiment a bispecific antibody molecule comprises a half antibody, or fragment thereof, having binding specificity for a first epitope and a half antibody, or fragment thereof, having binding specificity for a second epitope. In an embodiment a bispecific antibody molecule comprises a scFv, or fragment thereof, have binding specificity for a first epitope and a scFv, or fragment thereof, have binding specificity for a second epitope.

The antigen binding domain can be configured to bind to a tumor antigen. The terms “cancer associated antigen” or “tumor antigen” interchangeably refers to a molecule (typically a protein, carbohydrate or lipid) that is expressed on the surface of a cancer cell, either entirely or as a fragment (e.g., MHC/peptide), and which is useful for the preferential targeting of a pharmacological agent to the cancer cell. In some embodiments, a tumor antigen is a marker expressed by both normal cells and cancer cells, e.g., a lineage marker, e.g., CD19 on B cells. In some embodiments, a tumor antigen is a cell surface molecule that is overexpressed in a cancer cell in comparison to a normal cell, for instance, 1-fold over expression, 2-fold overexpression, 3-fold overexpression or more in comparison to a normal cell. In some embodiments, a tumor antigen is a cell surface molecule that is inappropriately synthesized in the cancer cell, for instance, a molecule that contains deletions, additions or mutations in comparison to the molecule expressed on a normal cell. In some embodiments, a tumor antigen will be expressed exclusively on the cell surface of a cancer cell, entirely or as a fragment (e.g., MHC/peptide), and not synthesized or expressed on the surface of a normal cell. In some embodiments, the CARs of the present invention includes CARs comprising an antigen binding domain (e.g., antibody or antibody fragment) that binds to a MHC presented peptide. Normally, peptides derived from endogenous proteins fill the pockets of Major histocompatibility complex (MHC) class I molecules, and are recognized by T cell receptors (TCRs) on CD8+T lymphocytes. The MHC class I complexes are constitutively expressed by all nucleated cells. In cancer, virus-specific and/or tumor-specific peptide/MHC complexes represent a unique class of cell surface targets for immunotherapy. TCR-like antibodies targeting peptides derived from viral or tumor antigens in the context of human leukocyte antigen (HLA)-A1 or HLA-A2 have been described (see e.g., Sastry et al., J Virol. 2011 85(5):1935-1942). For example, TCR-like antibody can be identified from screening a library, such as a human scFv phage displayed library.

The antigen binding domain can be connected to the transmembrane domain by a hinge region. In some instances, the transmembrane domain can be attached to the extracellular region of the CAR, e.g., the antigen binding domain of the CAR, via a hinge, e.g., a hinge from a human protein. For example, in one embodiment, the hinge can be a human Ig (immunoglobulin) hinge (e.g., an IgG4 hinge, an IgD hinge), a GS linker (e.g., a GS linker described herein), a KIR2DS2 hinge or a CD8a hinge.

With respect to the transmembrane domain, in various embodiments, a CAR can be designed to comprise a transmembrane domain that is attached to the extracellular domain of the CAR. A transmembrane domain can include one or more additional amino acids adjacent to the transmembrane region, e.g., one or more amino acid associated with the extracellular region of the protein from which the transmembrane was derived (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 up to 15 amino acids of the extracellular region) and/or one or more additional amino acids associated with the intracellular region of the protein from which the transmembrane protein is derived (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 up to 15 amino acids of the intracellular region). In some embodiments, the transmembrane domain is one that is associated with one of the other domains of the CAR e.g., in one embodiment, the transmembrane domain may be from the same protein that the signaling domain, costimulatory domain or the hinge domain is derived from. In some embodiments, the transmembrane domain is not derived from the same protein that any other domain of the CAR is derived from. In some instances, the transmembrane domain can be selected or modified by amino acid substitution to avoid binding of such domains to the transmembrane domains of the same or different surface membrane proteins, e.g., to minimize interactions with other members of the receptor complex. In some embodiments, the transmembrane domain is capable of homodimerization with another CAR on the cell surface of a CAR-expressing cell. In a different aspect, the amino acid sequence of the transmembrane domain may be modified or substituted so as to minimize interactions with the binding domains of the native binding partner present in the same CAR-expressing cell.

The transmembrane domain can comprise a transmembrane domain of a protein selected from the group consisting of the alpha, beta or zeta chain of the T-cell receptor, CD28, CD3 epsilon, CD45, CD4, CD5, CD8, CD9, CD16, CD22, CD33, CD37, CD64, CD80, CD86, CD134, CD137, CD154, KIRDS2, OX40, CD2, CD27, LFA-1 (CD11a, CD18), ICOS (CD278), 4-1BB (CD137), GITR, CD40, BAFFR, HVEM (LIGHTR), SLAMF7, NKp80 (KLRF1), CD160, CD19, IL2R beta, IL2R gamma, IL7Rα, ITGA1, VLA1, CD49a, ITGA4, IA4, CD49D, ITGA6, VLA-6, CD49f, ITGAD, CD11 d, ITGAE, CD103, ITGAL, CD11a, LFA-1, ITGAM, CD11 b, ITGAX, CD11c, ITGB1, CD29, ITGB2, CD18, LFA-1, ITGB7, TNFR2, DNAM1 (CD226), SLAMF4 (CD244, 2B4), CD84, CD96 (Tactile), CEACAM1, CRTAM, Ly9 (CD229), CD160 (BY55), PSGL1, CD100 (SEMA4D), SLAMF6 (NTB-A, Ly108), SLAM (SLAMF1, CD150, IPO-3), BLAME (SLAMF8), SELPLG (CD162), LTBR, PAG/Cbp, NKp44, NKp30, NKp46, NKG2D, and NKG2C, or a functional variant thereof. The transmembrane domain may be derived either from a natural or from a recombinant source. Where the source is natural, the domain may be derived from any membrane-bound or transmembrane protein. In some embodiments the transmembrane domain is capable of signaling to the intracellular domain(s) whenever the CAR has bound to a target.

The AP can comprise or can be derived from the protein of a coronavirus. The disease or disorder can be an infectious disease or disorder caused by a coronavirus, and the AP can comprise or can be derived from an antigenic protein of a coronavirus. The term “coronavirus” as used herein refers to a virus in the family Coronaviridae, which is in turn classified within the order Nidovirales. The coronaviruses are large, enveloped, positive-stranded RNA viruses. The coronaviruses have the largest genomes of the RNA viruses known in the art and replicate by a unique mechanism that results in a high frequency of recombination. The coronaviruses include antigenic groups I, II, and III. Nonlimiting examples of coronaviruses include SARS coronavirus (e.g., SARS-CoV and SARS-CoV-2), MERS coronavirus, transmissible gastroenteritis virus (TGEV), human respiratory coronavirus, porcine respiratory coronavirus, canine coronavirus, feline enteric coronavirus, feline infectious peritonitis virus, rabbit coronavirus, murine hepatitis virus, sialodacryoadenitis virus, porcine hemagglutinating encephalomyelitis virus, bovine coronavirus, avian infectious bronchitis virus, and turkey coronavirus, as well as chimeras thereof. Additional information related to coronavirus including classification, virion structure, genome structure, genetics and pathology is described, for example, in KV Holmes, Encyclopedia of Virology, 1999: 291-298, the content of which is incorporated herein by reference.

In some embodiments, a coronavirus described herein is in the genus of Alpha-coronavirus and the coronavirus antigens can be of or derived from any species or strains in the genus of Alpha-coronavirus. In some embodiments, a coronavirus described herein is in the genus of Beta-coronavirus and the coronavirus antigens can be of or derived from any species or strains in the genus of Beta-coronavirus. Member viruses in the genus of Alpha-coronavirus and Beta-coronavirus are enveloped, positive-strand RNA viruses that can infect mammals.

Tumor-Associated Antigens, Autoimmune Antigens, and Allergenic Antigens

Heterologous Antigens

The nucleic acid compositions herein described can encode a plurality of heterologous antigens (e.g, a plurality of disparate AP). In some embodiments, “heterologous antigens” are antigens that are of different origins, such as derived from pathogens of different taxonomic groups such as different strains, species, subgenera, genera, subfamilies or families and/or from antigenically divergent pathogens (e.g., variants thereof). Classification of viruses into various taxonomic groups is well understood by those skilled in the art. Each of the disparate AP of the plurality of disparate AP can differ with respect to each other.

In some embodiments, the plurality of disparate AP comprises: between about 2 and about 500 (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 120, 128, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, 500, or a number or a range between any two of these values) antigenic polypeptides that differ from each other; AP of a same protein type; and/or AP of different protein types.

The plurality of AP can be of a same protein type or corresponding proteins. AP of a same protein type may or may not have identical amino acid sequences, but generally share some sequence homology. For example, the coronavirus S proteins of different coronaviruses are of a same protein type or corresponding proteins. As another example, envelope proteins from different coronaviruses are considered the same protein type or corresponding proteins. In some embodiments, proteins of different coronavirus taxonomic groups having the same function are considered the same protein type or corresponding proteins. In some embodiments, coronavirus antigens of a same protein type have at least 50% sequence identity, for example at least 65%, 70%, 80%, 90%, 95%, 98%, 99%, or more sequence identity.

Alternatively, in some embodiments the plurality of AP can comprise coronavirus proteins of different protein types. AP of different protein types typically have different functions. For example, the plurality of AP can comprise coronavirus S proteins or portions thereof as well as other coronavirus proteins such as a coronavirus N protein or a portion thereof, a coronavirus HE protein or a portion thereof, a coronavirus papain-like protease or a portion thereof, a coronavirus 3CL protease or a portion thereof, and/or a coronavirus M protein or a portion thereof.

The plurality of disparate (e.g., heterologous) AP can comprise at least m pathogenic antigens of an mth infectious agent, wherein m is an integer greater than 2 (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 120, 128, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, 500, or a number or a range between any two of these values), and wherein each mth pathogenic antigen is different from one another (e.g., heterologous). In some embodiments, m is an integer greater than 50. The plurality of disparate AP can comprise two or more of a 1st pathogenic antigen (PA) of a 1st infectious agent (IA), a 2nd PA of a 2nd IA, a 3rd PA of a 3rd IA, a 4th PA of a 4th IA, a 5th PA of a 5th IA, a 6th PA of a 6th IA, a 7th PA of a 7th IA, a 8th PA of a 8th IA, a 9th PA of a 9th IA, a 10th PA of a 10th IA, a 1lth PA of a 1lth IA, a 12th PA of a 12th IA, a 13th PA of a 13th IA, a 14th PA of a 14th IA, a 15th PA of a 15th IA, a 16th PA of a 16th IA, a 17th PA of a 17th IA, a 18th PA of a 18th IA, a 19th PA of a 19th IA, a 20th PA of a 20th IA, a 21st PA of a 21st IA, a 22nd PA of a 22nd IA, a 23rd PA of a 23rd IA, a 24th PA of a 24th IA, a 25th PA of a 25th IA, a 26th PA of a 26th IA, a 27th PA of a 27th IA, a 28th PA of a 28th IA, a 29th PA of a 29th IA, a 30th PA of a 30th IA, a 31st PA of a 31st IA, a 32nd PA of a 32nd IA, a 33rd PA of a 33rd IA, a 34th PA of a 34th IA, a 35th PA of a 35th IA, a 36th PA of a 36th IA, a 37th PA of a 37th IA, a 38th PA of a 38th IA, a 39th PA of a 39th IA, a 40th PA of a 40th IA, a 41st PA of a 41st IA, a 42nd PA of a 42nd IA, a 43rd PA of a 43rd IA, a 44th PA of a 44th IA, a 45th PA of a 45th IA, a 46th PA of a 46th IA, a 47th PA of a 47th IA, a 48th PA of a 48th IA, a 49th PA of a 49th IA, and a 50th PA of a 50th IA. The 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th, 13th, 14th, 15th, 16th, 17th, 18th, 19th, 20th, 21st, 22nd, 23rd, 24th, 25th, 26th, 27th, 28th, 29th, 30th, 31st, 32nd, 33rd, 34th, 35th, 36th, 37th, 38th, 39th, 40th, 41st, 42nd, 43rd, 44th, 45th, 46th, 47th, 48th, 49th, and 50th pathogenic antigens can be the same or different from one another. The 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th, 13th, 14th, 15th, 16th, 17th, 18th, 19th, 20th, 21st, 22nd, 23rd, 24th, 25th, 26th, 27th, 28th, 29th, 30th, 31st, 32nd, 33rd, 34th, 35th, 36th, 37th, 38th, 39th, 40th, 41st, 42nd, 43rd, 44th, 45th, 46th, 47th, 48th, 49th, and 50th infectious agents can be the same or different from one another. The plurality of disparate (e.g., heterologous) AP can comprise a plurality of CoV antigens, a plurality of influenza antigens, and/or a plurality of HIV antigens.

The compositions provided herein can induce broadly protective anti-infectious agent responses by eliciting broadly neutralizing antibodies. As an example, broadly neutralizing antibodies are antibodies that can neutralize coronaviruses from a taxonomic group that is not only the same as but also differs from the taxonomic groups of the coronaviruses from which the coronavirus antigens used to elicit the antibodies are derived. Broadly neutralizing response can also be referred to as heterologously neutralizing response. In some embodiments, the compositions herein described can elicit broadly neutralizing antibodies that neutralize one or more infectious agents from a subfamily, genus, subgenus, species, and/or strain that differ from the subfamily, genus, subgenus, species, and/or strain of the infectious agents from which AP are derived.

Vectors and Carriers

The nucleic acid composition (e.g., a promoter operably linked to a polynucleotide comprising a first nucleic acid unit and a second nucleic acid unit) can be complexed or associated with one or more lipids or lipid-based carriers, thereby forming liposomes, lipid nanoparticles (LNPs), lipoplexes, and/or nanoliposomes, optionally encapsulating the nucleic acid composition. In some embodiments, the nucleic acid composition (e.g., a promoter operably linked to a polynucleotide comprising a first nucleic acid unit and a second nucleic acid unit) is, comprises, or further comprises, one or more vectors. At least one of the one or more vectors can be a viral vector, a plasmid, a transposable element, a naked DNA vector, a lipid nanoparticle (LNP), or any combination thereof. The viral vector can be an AAV vector, a lentivirus vector, a retrovirus vector, an adenovirus vector, a herpesvirus vector, a herpes simplex virus vector, a cytomegalovirus vector, a vaccinia virus vector, a MVA vector, a baculovirus vector, a vesicular stomatitis virus vector, a human papillomavirus vector, an avipox virus vector, a Sindbis virus vector, a VEE vector, a Measles virus vector, an influenza virus vector, a hepatitis B virus vector, an integration-deficient lentivirus (IDLV) vector, or any combination thereof. The transposable element can be piggybac transposon or sleeping beauty transposon. The polynucleotide(s) described herein can be comprised in the one or more vectors. The polynucleotide(s) described herein can be comprised in the same vector and/or different vectors. The polynucleotide(s) described herein can be situated on the same nucleic acid and/or different nucleic acids.

Vector technology is well known in the art and is described, for example, in Sambrook et al., 2012, MOLECULAR CLONING: A LABORATORY MANUAL, volumes 1-4, Cold Spring Harbor Press, NY), and in other virology and molecular biology manuals. Viruses, which are useful as vectors include, but are not limited to, retroviruses, adenoviruses, adeno-associated viruses, herpes viruses, and lentiviruses. In general, a suitable vector contains an origin of replication functional in at least one organism, a promoter sequence, convenient restriction endonuclease sites, and one or more selectable markers.

The one or more vectors can be a DNA vaccine. The DNA vaccine can be a plasmid-based DNA vaccine, a minicircle-based DNA vaccine, a bacmid-based DNA vaccine, a minigene-based DNA vaccine, a ministring DNA (linear covalently closed DNA vector) vaccine, a closed-ended linear duplex DNA (CELiD or ceDNA) vaccine, a Doggybone™ DNA vaccine, a dumbbell shaped DNA vaccine, or a minimalistic immunological-defined gene expression (MIDGE)-vector DNA vaccine.

The nucleic acid composition can be or can comprise mRNA. The composition (e.g., nucleic acid composition) can be an mRNA vaccine. The mRNA can be formulated in a lipid nanoparticle (LNP). The term “lipid nanoparticle”, also referred to as LNP, refers to a particle having at least one dimension on the order of nanometers (e.g., 1-1,000 nm) which includes one or more lipids. In some embodiments, such lipid nanoparticles comprise a cationic lipid and one or more excipient selected from neutral lipids, charged lipids, steroids and polymer conjugated lipids (e.g., a pegylated lipid). In some embodiments, the mRNA, or a portion thereof, is encapsulated in the lipid portion of the lipid nanoparticle or an aqueous space enveloped by some or all of the lipid portion of the lipid nanoparticle, thereby protecting it from enzymatic degradation or other undesirable effects induced by the mechanisms of the host organism or cells e.g. an adverse immune response. In some embodiments, the mRNA or a portion thereof is associated with the lipid nanoparticles. An LNP may comprise any lipid capable of forming a particle to which the one or more nucleic acid molecules are attached, or in which the one or more nucleic acid molecules are encapsulated. The term “lipid” refers to a group of organic compounds that are derivatives of fatty acids (e.g., esters) and are generally characterized by being insoluble in water but soluble in many organic solvents. Lipids are usually divided in at least three classes: (1) “simple lipids” which include fats and oils as well as waxes; (2) “compound lipids” which include phospholipids and glycolipids; and (3) “derived lipids” such as steroids.

The LNP can comprise one or more of an ionizable cationic lipid, a non-cationic lipid (e.g., a neutral lipid), a sterol, and a PEG-modified lipid. The LNP can comprise 0.5-15 mol % PEG-modified lipid, 5-25 mol % non-cationic lipid, 25-55 mol % sterol, and 20-60 mol % ionizable cationic lipid. The LNP can comprise 40-55 mol % ionizable cationic lipid, 5-15 mol % neutral lipid, 35-45 mol % sterol, and 1-5 mol % PEG-modified lipid. In some embodiments, the RNA (e.g., mRNA) of the disclosure is formulated in a lipid nanoparticle (LNP). Lipid nanoparticles typically comprise ionizable cationic lipid, non-cationic lipid, sterol and PEG lipid components along with the nucleic acid cargo of interest.

The LNP can comprise a cationic lipid. The cationic lipid is can be cationisable, i.e. it becomes protonated as the pH is lowered below the pKa of the ionizable group of the lipid, but is progressively more neutral at higher pH values. When positively charged, the lipid is then able to associate with negatively charged nucleic acids. In some embodiments, the cationic lipid comprises a zwitterionic lipid that assumes a positive charge on pH decrease. The LNP may comprise any lipid capable of forming a particle to which the one or more nucleic acid molecules are attached, or in which the one or more nucleic acid molecules are encapsulated. In some embodiments, the LNP may comprise any further cationic or cationisable lipid, i.e. any of a number of lipid species which carry a net positive charge at a selective pH, such as physiological pH. Such lipids include, but are not limited to, N,N-dioleyl-N,N-dimethylammonium chloride (DODAC); N-(2,3-dioleyloxy)propyl)-N,N,N-trimethylammonium chloride (DOTMA); N,N-distearyl-N,N-dimethylammonium bromide (DDAB); N-(2,3dioleoyloxy)propyl)-N,N,N-trimethylammonium chloride (DOTAP); 3-(N—(N′,N′dimethylaminoethane)-carbamoyl)cholesterol (DC-Chol), N-(1-(2,3-dioleoyloxy)propyl)N-2-(sperminecarboxamido)ethyl)-N,N-dimethylammonium trifluoracetate (DOSPA), dioctadecylamidoglycyl carboxyspermine (DOGS), 1,2-dioleoyl-3-dimethylammonium propane (DODAP), N,N-dimethyl-2,3-dioleoyloxy)propylamine (DODMA), and N-(1,2dimyristyloxyprop-3-yl)-N,N-dimethyl-N-hydroxyethyl ammonium bromide (DMRIE).

In some embodiments, a sterol comprises cholesterol, fecosterol, sitosterol, ergosterol, campesterol, stigmasterol, brassicasterol, tomatidine, ursolic acid, alpha-tocopherol, and mixtures thereof.

In some embodiments, the nucleic acid composition comprising an mRNA sequence is a modified mRNA sequence. In this context, a modification as defined herein can lead to a stabilization of the mRNA sequence provided herein. In some embodiments, there is thus provided a stabilized mRNA sequence comprising at least one coding region as defined herein (e.g. polynucleotide(s) encoding unit payload protein(s)). In some embodiments, the nucleic acid composition comprising an mRNA sequence may thus be provided as a “stabilized mRNA sequence”, that is to say as an mRNA that is essentially resistant to in vivo degradation (e.g. by an exo- or endo-nuclease). Such stabilization can be effected, for example, by a modified phosphate backbone of an mRNA provided herein. A backbone modification can be a modification in which phosphates of the backbone of the nucleotides contained in the mRNA are chemically modified. Nucleotides that can be used in this connection contain e.g. a phosphorothioate-modified phosphate backbone, such as at least one of the phosphate oxygens contained in the phosphate backbone being replaced by a sulfur atom. Stabilized mRNAs may further include, for example: non-ionic phosphate analogues, such as, for example, alkyl and aryl phosphonates, in which the charged phosphonate oxygen is replaced by an alkyl or aryl group, or phosphodiesters and alkylphosphotriesters, in which the charged oxygen residue is present in alkylated form. Such backbone modifications typically include, without implying any limitation, modifications from the group consisting of methylphosphonates, phosphoramidates and phosphorothioates (e.g. cytidine-5′-O-(1-thiophosphate)). The term “mRNA modification” as used herein may refer to chemical modifications comprising backbone modifications as well as sugar modifications or base modifications. In this context, a modified mRNA (sequence) as defined herein may contain nucleotide analogues/modifications, e.g. backbone modifications, sugar modifications or base modifications. A backbone modification can be a modification, in which phosphates of the backbone of the nucleotides contained in an mRNA compound comprising an mRNA sequence as defined herein are chemically modified. A sugar modification can be a chemical modification of the sugar of the nucleotides of the mRNA compound comprising an mRNA sequence as defined herein. Furthermore, a base modification can be a chemical modification of the base moiety of the nucleotides of the mRNA compound comprising an mRNA sequence. In this context, nucleotide analogues or modifications can be selected from nucleotide analogues, which are applicable for transcription and/or translation.

The mRNA provided herein can comprise a 5′ untranslated region (UTR), a 3′ UTR, and/or a cap (e.g., a CAP analogue). A modified mRNA sequence as defined herein, can be modified by the addition of a so-called “5′-CAP structure”, which can stabilize the mRNA as described herein. A 5′-CAP is an entity, typically a modified nucleotide entity, which generally “caps” the 5′-end of a mature mRNA. A 5′-CAP may typically be formed by a modified nucleotide, particularly by a derivative of a guanine nucleotide. In some embodiments, the 5′-CAP is linked to the 5′-terminus via a 5′-5′-triphosphate linkage. A 5′-CAP may be methylated, e.g. m7GpppN, wherein N is the terminal 5′ nucleotide of the nucleic acid carrying the 5′-CAP, typically the 5′-end of an mRNA. m7GpppN is the 5′-CAP structure, which naturally occurs in mRNA transcribed by polymerase II and is therefore in some embodiments is not considered as modification comprised in a modified mRNA in this context. Accordingly, a modified mRNA sequence may comprise a m7GpppN as 5′-cap, but additionally the modified mRNA sequence typically comprises at least one further modification as defined herein. A CAP analogue refers to a non-polymerizable di-nucleotide that has CAP functionality in that it facilitates translation or localization, and/or prevents degradation of the RNA molecule when incorporated at the 5′-end of the RNA molecule. Non-polymerizable means that the CAP analogue will be incorporated only at the 5′-terminus because it does not have a 5′ triphosphate and therefore cannot be extended in the 3′-direction by a template-dependent RNA polymerase. CAP analogues include, but are not limited to, a chemical structure selected from the group consisting of m7GpppG, m7GpppA, m7GpppC; unmethylated CAP analogues (e.g., GpppG); dimethylated CAP analogue (e.g., m2,7GpppG), trimethylated CAP analogue (e.g., m2,2,7GpppG), dimethylated symmetrical CAP analogues (e.g., m7Gpppm7G), or anti reverse CAP analogues (e.g., ARCA; m7,2′OmeGpppG, m7,2′dGpppG, m7,3′OmeGpppG, m7,3′dGpppG and their tetraphosphate derivatives) (Stepinski et al., 2001. RNA 7(10):1486-95). Further CAP analogues have been described previously (U.S. Pat. No. 7,074,596, WO2008/016473, WO2008/157688, WO2009/149253, WO2011/015347, and WO2013/059475).

The mRNA can comprise one or more modified nucleotides selected from the group comprising pseudouridine, N-1-methyl-pseudouridine, 2-aminoadenosine, 2-thiothymidine, inosine, pyrrolo-pyrimidine, 3-methyl adenosine, 5-methylcytidine, C-5 propynyl-cytidine, C-5 propynyl-uridine, 2-aminoadenosine, C5-bromouridine, C5-fluorouridine, C5-iodouridine, C5-propynyl-uridine, C5-propynyl-cytidine, C5-methylcytidine, 2-aminoadenosine, 7-deazaadenosine, 7-deazaguanosine, 8-oxoadenosine, 8-oxoguanosine, 0(6)-methylguanine, and 2-thiocytidine. The mRNA can comprise a modified nucleotide in place of one or more uridines. The modified nucleoside can be selected from pseudouridine (ψ), N 1-methyl-pseudouridine (m 1′), and 5-methyl-uridine (m5U). In some embodiments, a non-naturally occurring modified nucleotide or nucleoside of the disclosure is one as is generally known or recognized in the art. Non-limiting examples of such non-naturally occurring modified nucleotides and nucleosides can be found, inter alia, in published US application Nos. PCT/US2012/058519; PCT/US2013/075177; PCT/US2014/058897; PCT/US2014/058891; PCT/US2014/070413; PCT/US2015/36773; PCT/US2015/36759; PCT/US2015/36771; or PCT/IB 2017/051367 all of which are incorporated by reference herein.

Pharmaceutically Acceptable Compositions and Methods of Treatment

Disclosed herein include pharmaceutical compositions. In some embodiments, the pharmaceutical composition comprises: a nucleic acid composition disclosed herein and/or engineered cells disclosed herein. In some embodiments, the pharmaceutical composition further comprises one or more pharmaceutically acceptable carriers, diluents and/or excipients.

The phrase “pharmaceutically acceptable” is employed herein to refer to those agents, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

The phrase “pharmaceutically-acceptable carrier” as used herein means a pharmaceutically-acceptable material, composition or vehicle, such as a liquid or solid filler, diluent, excipient, solvent or encapsulating material, involved in carrying or transporting the subject chemical from one organ, or portion of the body, to another organ, or portion of the body. Each carrier must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not injurious to the subject. Some examples of materials which can serve as pharmaceutically-acceptable carriers include: (1) sugars, such as lactose, glucose and sucrose; (2) starches, such as corn starch and potato starch; (3) cellulose, and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; (4) powdered tragacanth: (5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository waxes; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; (10) glycols, such as propylene glycol; (1) polyols, such as glycerin, sorbitol, mannitol and polyethylene glycol; (12) esters, such as ethyl oleate and ethyl laurate; (13) agar; (14) buffering agents, such as magnesium hydroxide and aluminum hydroxide; (15) alginic acid; (16) pyrogen-free water; (17) isotonic saline; (18) Ringer's solution; (19) ethyl alcohol; (20) phosphate buffer solutions; and (21) other non-toxic compatible substances employed in pharmaceutical formulations.

Disclosed herein include methods of treating or preventing a disease or disorder in a subject in need thereof. In some embodiments, the method comprises: administering to the subject an effective amount of a nucleic acid composition disclosed herein, a pharmaceutical composition disclosed herein, or engineered cells disclosed herein, thereby treating or preventing the disease or disorder in the subject. The disease or disorder can be a disease or disorder caused by an infectious agent.

As used herein, the term “treatment” refers to an intervention made in response to a disease, disorder or physiological condition manifested by a patient. The aim of treatment may include, but is not limited to, one or more of the alleviation or prevention of symptoms, slowing or stopping the progression or worsening of a disease, disorder, or condition and the remission of the disease, disorder or condition. The term “treat” and “treatment” includes, for example, therapeutic treatments, prophylactic treatments, and applications in which one reduces the risk that a subject will develop a disorder or other risk factor. Treatment does not require the complete curing of a disorder and encompasses embodiments in which one reduces symptoms or underlying risk factors. In some embodiments, “treatment” refers to both therapeutic treatment and prophylactic or preventative measures. Those in need of treatment include those already affected by a disease or disorder or undesired physiological condition as well as those in which the disease or disorder or undesired physiological condition is to be prevented. As used herein, the term “prevention” refers to any activity that reduces the burden of the individual later expressing those symptoms. This can take place at primary, secondary and/or tertiary prevention levels, wherein: a) primary prevention avoids the development of symptoms/disorder/condition; b) secondary prevention activities are aimed at early stages of the condition/disorder/symptom treatment, thereby increasing opportunities for interventions to prevent progression of the condition/disorder/symptom and emergence of symptoms; and c) tertiary prevention reduces the negative impact of an already established condition/disorder/symptom by, for example, restoring function and/or reducing any condition/disorder/symptom or related complications. The term “prevent” does not require the 100% elimination of the possibility of an event. Rather, it denotes that the likelihood of the occurrence of the event has been reduced in the presence of the compound or method.

As used herein, the term “effective amount” refers to an amount sufficient to effect beneficial or desirable biological and/or clinical results.

In some embodiments, administering can comprise aerosol delivery, nasal delivery, vaginal delivery, rectal delivery, buccal delivery, ocular delivery, local delivery, topical delivery, intracisternal delivery, intraperitoneal delivery, oral delivery, intramuscular injection, intravenous injection, subcutaneous injection, intranodal injection, intratumoral injection, intraperitoneal injection, intradermal injection, or any combination thereof. In some embodiments, administering comprises: (i) isolating one or more cells from the subject; (ii) contacting said one or more cells with a nucleic acid composition provided herein, thereby generating engineered cells, optionally the contacting comprises transfection; and (iii) administering the one or more engineered cells into a subject after the contacting step. The method can comprise administering to the subject at least two doses of the nucleic acid composition, the pharmaceutical composition, and/or the engineered cells.

EXAMPLES

Some aspects of the embodiments discussed above are disclosed in further detail in the following examples, which are not in any way intended to limit the scope of the present disclosure.

Example 1
Stoichiometric Expression of Messenger Polycistrons by Eukaryotic Ribosomes

GV production requires the co-expression of multiple GV proteins (Gvps), which in prokaryotes are expressed from polycistronic operons at specific ratios determined by the strength of their respective ribosome binding sites or other regulatory mechanisms. These genes encode one or more structural proteins (e.g. GvpA) and an assortment of accessory proteins required for GV assembly (e.g. GvpN). While heterologous expression in bacteria is straightforward due to their compatibility with prokaryotic operons, co-expression of all the essential GV genes in mammalian cells at the optimal stoichiometry is difficult and requires specialized strategies. The principal challenge in mammalian expression involves the requirement for high expression of the major structural protein relative to the rest of the Gvps (FIGS. 1A-1B) and the intolerance of the major structural protein to non-native amino acids, which does not allow it to be linked using P2A.

Currently, transient heterologous expression of GVs in mammalian cells is achieved by the co-expression of GvpA and Gvps N,J,K,F,G,W from an aquatic cyanobacterium Anabaena flos-aquae on two separate mRNAs (one for GvpA and one for the other Gvps). The 7 accessory genes N->W are linked into a single self-cleavable ORF via P2A peptides on one expression cassette and GvpA is supplied in excess on a second cassette. This collection of GV expression cassettes was termed the Mammalian Acoustic Reporter Genes (mARGs) (FIG. 1C). While this approach produces functional GVs expressed in transient expression experiments (FIG. 1D), a more compact solution would be desirable to facilitate gene delivery and transcription independent expression. To achieve this, the SEMPER approach provided herein was employed to link the GvpA ORF upstream of the GvpN->W ORF (with the proteins in this ORF linked by P2A peptides) and translation initiation sequences for both were optimized. It was demonstrated herein that SEMPER-linked mARGs can produce gas vesicles with visible ultrasound contrast at similar levels compared to the two-cassette approach.

The results of this Example provide proof of principle for the use of the SEMPER compositions provided herein for a variety of applications where expression of two or more ORFs is required.

Transient SEMPER mARG Plasmid Design

Anabaena flos-aquae GvpA is a small 71 amino acid-long protein that lacks internal start codons, which makes it an excellent candidate for the upstream ORF in some embodiments. In order to find the optimal ribosome translation initiation ratio between the upstream (GvpA) and downstream (GvpsN->W) ORFs, the GvpA TIS sequence was varied while keeping the strongest TIS (ACCATGG) for the GvpsN->W ORF. Without being bound by any particular theory, this way the downstream ORF most efficiently captures the ribosomal translational activity that fails to initiate at GvpA. In order to monitor the cell-level ribosome translational activity distribution into the downstream ORF using flow-cytometry GFP was appended as the final P2A linked protein to the GvpsN->W ORF, resulting in GvpsN->W-GFP ORF. Finally, a third ORF encoding mCherry was added downstream of the SEMPER ORFs with its own independent translation initiation via IRES for normalization of the GFP signal for differences in transfection efficiency and transcriptional differences between experiments and between cells (FIG. 2A).

Varying the GvpA TIS Affects Expression of GvpN->W-GFP

Five different GvpA TIS with decreasing strengths (ACC, GGG, CCC, TTC and TTT) were tested and GFP and mCherry expression was measured in each cell using flow cytometry. GFP/mCherry ratio was calculated for each cell and compared to the theoretical maximum, which is produced when GvpA does not contain a start codon (TTTx) resulting in the GvpN->W-GFP start codon to be the first one encountered by the scanning ribosomes, and the theoretical minimum produced by a plasmid with GvpA-IRES-mCherry lacking GFP (pA-mCherry). Transient cotransfection of the standard two-cassette mARG plasmids with GvpA-IRES-mCherry and GvpN->W-GFP, both with the strongest TIS, was included for comparison. The results show that the strength of the GvpA TIS is inversely proportional to the GFP expression after 12 and 72 hours of expression, consistent with the leaky scanning model (FIGS. 2B-2C).

Relative Ribosome Translation Initiation Affects Gas Vesicle Expression and Acoustic Properties

The produced gas vesicles were characterized using two ultrasound modalities, namely BURST imaging, which derives contrast from the collapse of GVs when a high acoustic pressure is applied, and amplitude modulation imaging (AM), which derives contrast from the nonlinear scattering of ultrasound signal by buckling GVs with reduced shell stiffness. For this experiment, transiently transfected HEK293T cells were harvested after 3 days of expression and embedded in agarose phantoms for ultrasound imaging. The results show that GVs produced with the strongest GvpA TIS produced the highest AM signal which dropped significantly with decreasing TIS strength (FIG. 3A). Interestingly, the BURST signal did not start to drop until the fourth strongest TIS (TTC), which, without being bound by any particular theory, implies that redistribution of the ribosome flux between the two ORFs, and also their relative expression, can modulate not only the gas vesicle expression level but also acoustomechanic properties of GVs (FIG. 3B). Lastly, the cells were lysed and GVs were purified for TEM imaging. All TIS strengths produced visible Gas Vesicle structures characterized by their inherent TEM contrast in the absence of staining. The formation of GVs requires the expression of GvpA and the accessory proteins, confirming that both the upstream and downstream ORFs are translated in all the constructs that contain start codons on both ORFs (FIG. 3C).

In at least some of the previously described embodiments, one or more elements used in an embodiment can interchangeably be used in another embodiment unless such a replacement is not technically feasible. It will be appreciated by those skilled in the art that various other omissions, additions and modifications may be made to the methods and structures described above without departing from the scope of the claimed subject matter. All such modifications and changes are intended to fall within the scope of the subject matter, as defined by the appended claims.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Any reference to “or” herein is intended to encompass “and/or” unless otherwise stated.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms.

In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible sub-ranges and combinations of sub-ranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as “up to,” “at least,” “greater than,” “less than,” and the like include the number recited and refer to ranges which can be subsequently broken down into sub-ranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 articles refers to groups having 1, 2, or 3 articles. Similarly, a group having 1-5 articles refers to groups having 1, 2, 3, 4, or 5 articles, and so forth.

While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
