This application includes an electronically submitted sequence listing in .txt format. The .txt file contains a sequence listing entitled “01750327.TXT” The sequence listing contained in this .txt file is part of the specification and is hereby incorporated by reference herein in its entirety.
The present disclosure relates generally to bacterial delivery vehicles and their use in efficient transfer of a desired payload into a target bacterial cell population. More specifically, the present disclosure relates to bacterial delivery vehicles with desired host range that can be used to efficiently transfer in vivo the desired payload to one or more target bacterial cell populations of the microbiome.
Encapsidated DNA in bacterial delivery particles can be used as a method to deliver genetic material into a target bacterial population. Several systems exist that allow the packaging of exogenous DNA into phage particles, for example bacteriophage lambda, in a laboratory setting. Such systems include, for example, a system that directly produces the packaged particles in a bacterial cell and in vitro cell-free systems [1]-[3]. These systems exploit the fact that the addition of a cognate packaging site to an exogenous DNA vector (called phagemid, and more specifically cosmid in the presence of a cos packaging site) allows for the efficient packaging of this payload into a mature viral particle. This approach has been used in many different applications, for example for the generation of cosmid libraries or the transduction of specific genes into bacteria [2], [4]. Most of these transduction assays are performed in laboratory conditions: cells are cultured in a controlled growth media, such as LB, and the transduction protocol is carried out in a buffer with known solute concentrations.
For in vivo applications, such as oral delivery of encapsidated DNA into particles, the need exists for bacterial delivery vehicles that can be given at high enough concentrations to reach all the target cells; hence, a payload that gives high enough titers is essential to optimize the in vivo activity as well as the manufacturing process. The packaged DNA into particles also needs to be able to bind its target cell strongly and long enough for the injection process to occur.
Although it was previously shown that the presence of side tail fiber is not necessary for lambda-mediated in vitro transduction experiments in K-12 laboratory strains [5], it is demonstrated herein that side tail fiber is actually necessary to optimize in vivo activity in a treated subject. The present disclosure provides delivery vehicles for in vivo delivery to a target host bacterium of interest, such as those in the gut of a treated subject.
The present disclosure relates to lambdoïd bacterial delivery vehicles and their use in efficient in vivo transfer of a desired payload into a target bacterial cell. The desired payload includes nucleic acid molecules that encode a gene of interest.
A lambdoïd bacterial delivery vehicle for use in in vivo delivery of a DNA payload of interest into a targeted bacterial cell population is provided. In one embodiment, the bacterial delivery vehicle comprises one or more receptor binding protein(s) (RBP). As used herein, a receptor binding protein or RBP is a polypeptide that recognizes, and optionally binds and/or modifies or degrades a substrate located on the bacterial outer envelope, such as, without limitation, bacterial outer membrane, LPS, capsule, protein receptor, channel, structure such as the flagellum, pili, secretion system. The substrate can be, without limitation, any carbohydrate or modified carbohydrate, any lipid or modified lipid, any protein or modified protein, any amino acid sequence, and any combination thereof.
In one embodiment, the bacterial delivery vehicle comprises one or more RBPs selected from the group consisting of a functional lambdoïd side tail fiber protein (herein “STF protein”), a functional lambdoïd gpJ protein and a functional lambdoïd gpH protein. In another embodiment, the bacterial delivery vehicle may comprise two or more proteins selected from the group consisting of a functional lambdoïd side tail fiber protein (herein “STF protein”), a functional lambdoïd gpJ protein and a functional lambdoïd gpH protein. In a particular embodiment, the bacterial delivery vehicle comprises a functional lambdoïd side tail fiber protein (herein “STF protein”) and a functional lambdoïd gpJ protein. In yet another embodiment, the bacterial delivery vehicle comprises a functional lambdoïd side tail fiber protein (herein “STF protein”), a functional lambdoïd gpJ protein and a functional lambdoïd gpH protein. In another aspect, the bacterial delivery vehicle comprises a functional lambdoïd gpJ protein and a functional lambdoïd gpH protein. In another aspect, the bacterial delivery vehicle comprises (i) a functional lambdoïd side tail fiber protein. In addition to a functional STF protein, the bacterial delivery vehicle may further comprise (ii) a functional lambdoïd gpJ protein; and optionally (iii) a functional lambdoïd gpH protein.
In an embodiment, the STF protein, the gpJ protein and/or the gpH protein are a wild type lambda STF, gpJ and/or gpH protein. Alternatively, the STF protein, the gpJ protein and/or the gpH protein are recombinant proteins, preferably non-naturally occurring recombinant proteins. In particular, the recombinant STF protein, gpJ protein and/or gpH protein may be engineered to target the transfer of the DNA payload of interest into the targeted bacterial cell. In a non-limiting example, the recombinant STF protein may be engineered to advantageously possess enzymatic activity such as depolymerase activity and the target bacterial cell may be an encapsulated bacterial cell. Such depolymerase activity is found to increase delivery efficiency, and includes activity associated with an endosialidase such as, for example, a K1F endosialidase or activity associated with a lyase such as, for example, K5 lyase.
Recombinant STF proteins include, for example, engineered chimeric STF proteins and in some instances, the disclosure provides their associated chaperone (also called accessory) proteins. Such chaperone proteins assist in the folding of the chimeric STF protein. The recombinant engineered chimeric STF protein may comprise a fusion between a portion of a STF protein derived from a lambdoïd bacteriophage, preferably a lambda or lambda-like bacteriophage, and a portion of a STF protein derived from a corresponding STF protein derived from a different bacteriophage. Such chimeric STF protein may comprise a fusion between the N-terminal domain of a STF from a lambdoïd bacteriophage, preferably a lambda or lambda-like bacteriophage, and the C-terminal domain of a different STF. In an embodiment, the chimeric STF protein comprises or consists of the amino acid sequence of SEQ ID NO: 14, the amino acid sequence of SEQ ID NO: 16, the amino acid sequence of SEQ ID NO: 17, the amino acid sequence of SEQ ID NO: 19, the amino acid sequence of SEQ ID NO: 21, or the amino acid sequence of SEQ ID NO: 50. In a particular embodiment, the chimeric STF protein is STF-V10 (SEQ ID NO: 44). Other examples of chimeric STF proteins include STF-V10f (SEQ ID NO: 45), STF-V10a (SEQ ID NO: 46) and STF-V10h (SEQ ID NO: 47). The present disclosure also provides synthetic bacterial delivery vehicles that are characterized by the presence of an engineered branched receptor binding multi-subunit protein complex (“branched-RBP”). The engineered branched-RBP comprises two or more associated receptor binding proteins, derived from bacteriophages, which associate with one another based on the presence of interaction domains (IDs). In a particular embodiment, said engineered branched-RBP comprises two or more associated STF, derived from bacteriophages, which associate with one another based on the presence of IDs. The association of one subunit with another can be non-covalent or covalent. Each of the polypeptide subunits contain IDs that function as “anchors” for association of one subunit RBP with another. In specific embodiments the branched-RBP may comprise multiple RBP subunits, including, for example, two, three, four, etc. subunits. The individual RBP subunit may bring different biological functions to the overall engineered branched-RBP. Such functions include but are not limited to host recognition and enzymatic activity. Such enzymatic activity includes depolymerase activity.
Accordingly, bacterial delivery vehicles are provided which enable transfer of a nucleic acid payload, encoding a protein or nucleic acid of interest, into a desired target bacterial host cell wherein said bacterial delivery vehicles are characterized by having a chimeric STF and/or a branched-RBP as disclosed herein.
Bacterial delivery vehicles are also provided that comprise recombinant gpJ proteins. Such gpJ proteins include recombinant gpJ proteins, including chimeric proteins, that permit recognition of a bacterial cell receptor other than the LamB OMP receptor which is the natural lambda phage receptor on the bacterial cell surface (14). The recombinant engineered chimeric gpJ protein may comprise a fusion between a portion of a gpJ protein derived from a lambdoïd bacteriophage, preferably a lambda or lambda-like bacteriophage, and a portion of a gpJ protein derived from a corresponding gpJ protein derived from a different bacteriophage. Such chimeric gpJ protein may comprise a fusion between the N-terminal domain of a gpJ protein from a lambdoïd bacteriophage, preferably a lambda or lambda-like bacteriophage, and the C-terminal domain of a different gpJ protein. In an embodiment, the gpJ protein comprises or consists of the amino acid sequence of SEQ ID NO: 10, 11, 12, 13 or 49.
Bacterial delivery vehicles are also provided that comprise recombinant gpH proteins. Such gpH proteins include recombinant gpH proteins that permit or allow improved entry of bacterial vectors in cells having deficiencies or alterations in permease complexes. The recombinant engineered chimeric gpH protein may comprise a fusion between a portion of a gpH protein derived from a lambdoïd bacteriophage, preferably a lambda or lambda-like bacteriophage, and a portion of a gpH protein derived from a corresponding gpH protein derived from a different bacteriophage. Such chimeric gpH protein may comprise a fusion between the N-terminal domain of a gpH protein from a lambdoïd bacteriophage, preferably a lambda or lambda-like bacteriophage, and the C-terminal domain of a different gpH protein. In an embodiment, the gpH protein comprises or consists of the amino acid sequence of SEQ ID NO: 23 or 24.
In certain aspects, the bacterial delivery vehicles provided herein, are vehicles wherein the recombinant STF protein, gpJ protein and/or gpH protein are engineered to increase the efficiency of transfer of the DNA payload into the targeted bacterial cell.

In order to better understand the subject matter that is disclosed herein and to exemplify how it may be carried out in practice, embodiments will now be described, by way of non-limiting example, with reference to the accompanying drawings. With specific reference to the drawings, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of embodiments of the disclosure.
The present disclosure relates to bacterial delivery vehicles with desired host ranges that can be used to efficiently transfer the desired payload in vivo to one or more target bacterial cells of the microbiota of a subject.
Disclosed herein are methods and compositions for in vivo delivery of a desired payload into the microbiome of a subject. Such delivery vehicles are engineered to contain as part of their payload, nucleic acids encoding RNA molecules or proteins that may be useful for treatment of disorders and diseases of a subject. Such nucleic acids may encode generally, any molecules, compounds and proteins, as non-limiting examples.
The bacterial delivery vehicles provided herein enable transfer of a nucleic acid payload, encoding a protein or nucleic acid of interest, into a desired target bacterial host cell. As used herein, the term “delivery vehicle” refers to any means that allows the transfer of a payload into a bacterium. There are several types of delivery vehicles encompassed by the present disclosure including, without limitation, bacteriophage scaffold, virus scaffold, chemical based delivery vehicle (e.g., cyclodextrin, calcium phosphate, cationic polymers, cationic liposomes), protein-based or peptide-based delivery vehicle, lipid-based delivery vehicle, nanoparticle-based delivery vehicles, non-chemical-based delivery vehicles (e.g., transformation, electroporation, sonoporation, optical transfection), particle-based delivery vehicles (e.g., gene gun, magnetofection, impalefection, particle bombardment, cell-penetrating peptides) or donor bacteria (conjugation). Any combination of delivery vehicles is also encompassed by the present disclosure. The delivery vehicle can refer to a bacteriophage derived scaffold and can be obtained from a natural, evolved or engineered capsid.
In one aspect, bacterial delivery vehicles with desired target host ranges are provided for use in in vivo transfer of a payload to the microbiome of a subject. The bacterial delivery vehicle may comprise one or more proteins selected from the group consisting of a functional lambdoïd side tail fiber protein (herein “STF protein”), a functional lambdoïd gpJ protein and a functional lambdoïd gpH protein. In another embodiment, the bacterial delivery vehicle may comprise two or more proteins selected from the group consisting of a functional lambdoïd side tail fiber protein, a functional lambdoïd gpJ protein and a functional lambdoïd gpH protein. In a particular embodiment, the bacterial delivery vehicle comprises a functional lambdoïd STF protein and a functional lambdoïd gpJ protein. In yet another embodiment, the bacterial delivery vehicle may comprise a functional lambdoïd STF protein, a functional lambdoïd gpJ protein and a functional lambdoïd gpH protein. In another aspect, the bacterial delivery vehicle may comprise a functional lambdoïd gpJ protein and a functional lambdoïd gpH protein. In another aspect, the bacterial delivery vehicle may comprise (i) a functional lambdoïd STF protein. In addition to a functional STF protein, the bacterial delivery vehicle may further comprise (ii) a functional lambdoïd gpJ protein; and optionally (iii) a functional lambdoïd gpH protein.
In an embodiment, the functional STF protein, the functional gpJ protein and/or the functional gpH protein are respectively wild type lambda STF, gpJ and/or gpH proteins. Alternatively, the functional STF protein, the functional gpJ protein and/or the functional gpH protein are recombinant proteins.
As used herein, the term “recombinant protein” refers to non-naturally occurring proteins, in particular engineered proteins obtained by recombination technique. Such recombinant proteins include, for example, engineered chimeric proteins.
As used herein, a functional protein means in general a protein with a biological activity; more specifically a functional wild type, recombinant protein, variant, fusion or fragment herein relates to a wild type, recombinant protein, variant, fusion or fragment contributing to the efficient delivery of a DNA payload into a target strain. The efficiency threshold depends on a number of factors such as the type of protein, type of target strain and type of environment. For instance, STF and gpJ proteins allow for recognition, binding (and in some cases also degradation) of an extracellular epitope such as LPS, capsules and outer membrane proteins; gpH proteins allow for an efficient injection and hence successful passage of the DNA payload through the periplasm.
In the context of the present disclosure, a protein, such as STF, gpJ and gpH proteins, may be determined as being functional by titrating packaged phagemids containing said protein on bacterial cells known to display receptors recognized by said protein and comparing it to the titer obtained with the same packaged phagemids on bacterial cells known to display receptors which are not recognized by said protein.
Such recombinant chimeric STF protein may comprise a fusion between a portion of a STF protein derived from a lambdoïd bacteriophage, preferably a lambda or lambda-like bacteriophage, and a portion of a STF protein derived from a STF protein derived from a different bacteriophage (herein referred to also as a “chimeric receptor binding protein” or “chimeric RBP”), in particular from a different lambdoïd bacteriophage or from a non-lambdoïd bacteriophage. Such chimeric STF protein may comprise a fusion between the N-terminal domain of a STF protein from a lambdoïd bacteriophage, preferably a lambda or lambda-like bacteriophage, and the C-terminal domain of a different STF. As used herein, a receptor binding protein or RBP may be a STF derived polypeptide that recognizes, and optionally binds and/or modifies or degrades a substrate located on the bacterial outer envelope, such as, without limitation, bacterial outer membrane, LPS, capsule, protein receptor, channel, structure such as the flagellum, pili, secretion system. The substrate can be, without limitation, any carbohydrate or modified carbohydrate, any lipid or modified lipid, any protein or modified protein, any amino acid sequence, and any combination thereof.
As used herein, lambdoïd bacteriophages comprise a group of related viruses that infect bacteria. The viruses are termed lambdoïd because one of the first members to be described was lambda (λ). Lambdoid bacteriophages are members of the Caudovirus order (also known as tailed bacteriophages) and include those bacteriophages with similar lifestyles, including, for example, the ability to recombine when intercrossed, possession of identical pairs of cohesive ends, and prophages that are inducible by ultraviolet irradiation. Although members of the order may have genomes that vary at the nucleotide level, they carry regions of sufficient nucleotide sequence identity to guide recombination between themselves typically giving rise to a fully functional phage that has all the necessary genes. (See, for example, Casjens and Hendrix (2015) Virology 479-480:310-330). For purposes of the present disclosure, lambdoïd bacteriophages for use as delivery vehicles, as well as lambdoïd STF, gpH and gpJ proteins for use, would be understood generally by one skilled in the art.
Lambdoid phages can be defined as belonging to the lambda supercluster based on genomic analysis [6]. Within this supercluster, several clusters can be distinguished, each having a prototypical phage. The phage-like clusters and their members (between brackets) are: Lambda-like (lambda (k), HK630, HK629), phi80-like (phi80, HK225, mEp237), N15-like (N15, PY54, phiKO2), HK97-like (HK97, HK022, HK75, HK106, HK140, HK446, HK542, HK544, HK633, mEpX1, mEpX2, mEp234, mEp235, mEp390, ENT39118), ES18-like (ES18, Oslo, SPN3UB), Gifsy-2-like (gifsy-2, gifsy-1, Fels-1, mEp043, mEp213, CP-1639, CTD-Iø, mEp640, FSL SP-016), BP-4795-like (BP-4795, 2851, stx2-1717, YYZ-2008), SfV-like (SfV, SfII, SfIV, SfI, øP27, ST64B), P22-like (P22, L, SPN9CC, ST64T, ST104, ST160, epsilon34, g341, SE1, Emek, φ20, IME10, Sf6, HK620, CUS-3, SPC-P1), APSE-1-like (APSE-1, APSE-2), 933W-like (933W, stx1ø, stx2ø-I, stx2ø-II, stx2-86, min27, ø24B, P13374, TL-2011c, VT2-sakai, VT2ø_272), HK639-like (HK639), øES15-like (øES15), HS2-like (HS2), ENT47970-like (ENT47670), ZF40-like (ZF40), øEt88-like (øEt88).
In the present disclosure a lambdoïd STF protein includes, for example, a protein comprising or consisting of an amino acid sequence having at least 75% identity up to amino acid corresponding to amino acid 130 of lambda STF (Uniprot P03764 SEQ ID NO: 14), in particular up to amino acid 130 of said lambda STF; a lambdoïd gpJ protein includes, for example, a protein comprising or consisting of an amino acid sequence having at least 35% identity up to an amino acid corresponding to amino acid 606 of lambda gpJ (Uniprot P03749 SEQ ID NO: 10), in particular up to amino acid 606 of said lambda gpJ; and a lambdoïd gpH protein includes, for example, a protein comprising or consisting of an amino acid sequence having at least 40% identity over the complete length of lambda gpH (Uniprot P03736 SEQ ID NO: 23) and considering that the stretch of amino acids between positions 189 and 391 may bear little or no identity at all. A lambdoïd bacterial delivery vehicle includes a bacterial delivery vehicle comprising a functional lambdoïd stf protein and/or a functional lambdoïd gpJ protein and/or functional lambdoïd gpH protein, which each may have an altered host range compared to the wild-type lambda phage.
In one aspect, the STF protein includes a protein that comprises or consists of an amino acid sequence with at least 80, 85, 90, 95, 96, 97, 98, or 99% sequence identity with the wild type lambda stf protein amino acid sequence of SEQ ID NO: 14, or with any of the recombinant STF proteins, fusions, variants or fragments disclosed herein. In one aspect, the gpJ protein includes a protein that comprises or consists of an amino acid sequence with at least 80, 85, 90, 95, 96, 97, 98, or 99% sequence identity with the wild type gpJ protein amino acid sequence of SEQ ID NO: 10, or with any of the recombinant gpJ proteins, fusions, variants or fragments disclosed herein. In one aspect, the gpH protein includes a protein that comprises or consists of an amino acid sequence with at least 80, 85, 90, 95, 96, 97, 98, or 99% sequence identity with the wild type gpH protein amino acid sequence of SEQ ID NO: 23, or with any of the recombinant gpH proteins, fusions, variants or fragments disclosed herein. In another aspect, nucleic acids encoding for such wild type, or recombinant, STF, gpH and gpJ proteins are provided herein.
As used herein, the percent homology between two sequences is equivalent to the percent identity between the two sequences. The percent identity is calculated in relation to polymers (e.g., polynucleotide or polypeptide) whose sequences have been aligned. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences (i.e., % homology=# of identical positions/total # of positions×100), taking into account the number of gaps, and the length of each gap, which need to be introduced for optimal alignment of the two sequences. The comparison of sequences and determination of percent identity between two sequences can be accomplished using a mathematical algorithm, as described in the non-limiting examples below.
The percent identity between two amino acid sequences can be determined using the algorithm of E. Meyers and W. Miller (Comput. Appl. Biosci., 4: 11-17 (1988)) which has been incorporated into the ALIGN program (version 2.0), using a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4. In addition, the percent identity between two amino acid sequences can be determined using the Needleman and Wunsch (J. Mol. Biol. 48:444-453 (1970)) algorithm which has been incorporated into the GAP program in the GCG software package (available at www.gcg.com), using a BLOSUM62 matrix, a BLOSUM30 matrix or a PAM250 matrix, and a gap weight of 16, 14, 12, 10, 8, 6, or 4 and a length weight of 1, 2, 3, 4, 5, or 6. In a specific embodiment the BLOSUM30 matrix is used with gap open penalty of 12 and gap extension penalty of 4.
A variety of different lambdoïd bacterial delivery vehicles are provided as a means for transfer of a payload into a target bacterial cell population. Such bacterial delivery vehicles include those that comprise one or more wild type lambdoïd STF, gpH and gpJ proteins.

Included are delivery vehicles wherein the three STF, gpH and gpJ proteins are wild-type and those delivery vehicles wherein the three STF, gpH and gpJ proteins are recombinant, fusions, variants or fragments.
The present disclosure provides delivery vehicles, for example, comprising a chimeric receptor binding protein (RBP), wherein the chimeric RBP comprises a fusion between an N-terminal domain of a RBP from a lambdoïd bacteriophage, preferably a lambda or lambda-like bacteriophage, and a C-terminal domain of a different bacteriophage RBP. Such bacteriophage RBPs, from which the chimeric RBP are derived, include, for example, “L-shape fibers”, “side tail fibers (STFs)”, “long tail fibers” or “tailspikes.” Such bacteriophage RBPs, from which the chimeric RBP are derived, may be wild-type RBPs or RBP variants, preferably wild-type RBPs. Such chimeric RBPs include those having an altered host range and/or biological activity such as, for example, depolymerase activity. In an embodiment, the chimeric RBPs have a host range that is directed to specific bacterial cells of the host or subject microbiome. In one specific aspect, the different RBP of the chimeric receptor binding protein (RBP) is derived from any bacteriophage or from any bacteriocin.

Recombinant RBP proteins as disclosed herein may need their associated chaperone (also called accessory) proteins for proper folding. Such chaperone proteins assist in the folding of the chimeric RBP protein. For example, the lambda STF protein comprising or consisting of the amino acid sequence SEQ ID NO: 14 needs its associated protein, which typically comprises or consists of the amino acid sequence SEQ ID NO: 15, for proper folding. The need of an associated chaperone protein for proper folding of said chimeric RBP protein typically depends on the RBP from which the C-terminal region of the chimeric RBP is derived. For example, the chimeric STF protein STF75 comprising or consisting of the amino acid sequence SEQ ID NO: 17 needs its associated chaperone protein, which typically comprises or consists of the amino acid sequence SEQ ID NO: 18, and is typically encoded by the nucleic acid sequence SEQ ID NO: 34, for proper folding. For example, the chimeric STF protein STF-EB6 comprising or consisting of the amino acid sequence SEQ ID NO: 19 needs its associated chaperone protein, which typically comprises or consists of the amino acid sequence SEQ ID NO: 20 and is typically encoded by the nucleic acid sequence SEQ ID NO: 32, for proper folding. For example, the chimeric STF protein STF23 comprising or consisting of the amino acid sequence SEQ ID NO: 21 needs its associated chaperone protein, which typically comprises or consists of the amino acid sequence SEQ ID NO: 22 and is typically encoded by the nucleic acid sequence SEQ ID NO: 36, for proper folding. For example, the chimeric STF protein STF lambda-P2 comprising or consisting of the amino acid sequence SEQ ID NO: 50 needs its associated chaperone protein, which typically comprises or consists of the amino acid sequence SEQ ID NO: 57 and is typically encoded by the nucleic acid sequence SEQ ID NO: 58, for proper folding. Said chaperone protein may remain attached to said chimeric STF protein after folding. Accordingly, in some embodiments, the bacterial delivery vehicles disclosed herein may further comprise the chaperone protein associated with the chimeric STF protein that said vehicle comprises. Alternatively, said chaperone protein may not remain attached to said chimeric STF protein after folding, and may for example be proteolysed, in particular auto-proteolysed. Accordingly, in some embodiments, the bacterial delivery vehicles disclosed herein do not comprise the chaperone protein associated with the chimeric STF protein that said vehicle comprises.
The present disclosure also provides synthetic bacterial delivery vehicles that are characterized by the presence of an engineered branched receptor binding multi-subunit protein complex (“branched-RBP”). Such delivery vehicles may be used to transfer a payload of interest into a bacterial cell of the microbiome. The engineered branched-RBP comprises two or more associated receptor binding proteins, derived from bacteriophages, which associate with one another based on the presence of interaction domains (IDs). The association of one subunit with another can be non-covalent or covalent. Each of the polypeptide subunits contain IDs that function as “anchors” for association of one subunit RBP with another. In specific embodiments, the branched-RBP may comprise multiple RBP subunits, including, for example, two, three, four, etc. subunits.
The individual RBP subunit may bring different biological functions to the overall engineered branched-RBP. Such functions include but are not limited to host recognition and enzymatic activity.

No. 16/726,033, each of which is incorporated by reference in their entirety).
Bacterial delivery vehicles are also provided that comprise recombinant gpJ proteins. Such gpJ proteins include recombinant gpJ proteins, including chimeric proteins, that permit recognition of a bacterial cell receptor other than the LamB OMP receptor. It is known that receptor-recognition activity of gpJ lies in the C-terminal part of the protein, with a fragment as small as 249aa conferring capability of binding to the LamB receptor [5].

Bacterial delivery vehicles are also provided that comprise recombinant gpH proteins. Such gpH proteins include recombinant gpH proteins that permit or allow improved entry of bacterial vectors in cells having deficiencies or alterations in permease complexes. The recombinant engineered chimeric gpH protein may comprise a fusion between a portion of a gpH protein derived from a lambdoïd bacteriophage, preferably a lambda or lambda-like bacteriophage, and a portion of a gpH protein derived from a corresponding gpH protein derived from a different bacteriophage.

In a particular embodiment, said bacterial delivery vehicle comprises chimeric STF-V10h variant as disclosed above and chimeric 1A2 variant as disclosed above.
In aspects, the bacterial delivery vehicles provided herein, are vehicles comprising recombinant STF protein(s) (including but not limited to chimeric and branched RBPs), gpJ protein(s) and/or gpH protein(s) that are engineered to increase the efficiency of transfer of the DNA payload into the targeted bacterial cell population. Such bacterial cell populations include for example E. coli. and other bacterial species of interest.
It has also been demonstrated herein that the size of the packaged genome can have effects on the efficiency of packaging.
Nucleic acid molecules encoding the wild type, as well as recombinant STF, gpJ, and gpH proteins disclosed herein are provided. Such nucleic acids may be included in vectors such as bacteriophages, plasmids, phagemids, viruses, and other vehicles which enable transfer and expression of the recombinant STF, gpJ, and gpH encoding nucleic acids.
In a particular embodiment, nucleic acids are included in a single vector. In a more particular embodiment, said vector comprises or consists of the nucleic acid sequence SEQ ID NO: 47.
The bacterial delivery vehicles provided herein enable transfer of a nucleic acid payload, encoding a protein or nucleic acid of interest, into a desired target bacterial host cell. As used herein, the term “delivery vehicle” refers to any means that allows the transfer of a payload into a bacterium. There are several types of delivery vehicles encompassed by the present disclosure including, without limitation, bacteriophage scaffold, virus scaffold, chemical based delivery vehicle (e.g., cyclodextrin, calcium phosphate, cationic polymers, cationic liposomes), protein-based or peptide-based delivery vehicle, lipid-based delivery vehicle, nanoparticle-based delivery vehicles, non-chemical-based delivery vehicles (e.g., transformation, electroporation, sonoporation, optical transfection), particle-based delivery vehicles (e.g., gene gun, magnetofection, impalefection, particle bombardment, cell-penetrating peptides) or donor bacteria (conjugation). Any combination of delivery vehicles is also encompassed by the present disclosure. The delivery vehicle can refer to a bacteriophage derived scaffold and can be obtained from a natural, evolved or engineered capsid.
Delivery vehicles include packaged phagemids, as well as bacteriophage, as disclosed herein. An Eligobiotic® is a packaged phagemid, i.e a payload encapsidated in a phage-derived capsid. The engineering of such delivery vehicles is well known to those skilled in the art. Such engineering techniques may employ production cell lines engineered to express the STF, gpJ and gpH proteins disclosed herein. In one aspect, bacterial delivery vehicles with desired target host ranges are provided for use in transfer of a payload to the microbiome of a host. The bacterial delivery vehicles may be characterized by combinations of wild-type and recombinant STF, gpJ and gpH proteins.
The present disclosure also provides a production cell line producing the bacterial delivery vehicles disclosed herein.
Generation of packaged phagemids and bacteriophage particles are routine techniques well-known to one skilled in the art. In an embodiment, a satellite phage and/or helper phage may be used to promote the packaging of the payload in the delivery vehicles disclosed herein. Helper phages provide functions in trans and are well known to the man skilled in the art. The helper phage comprises all the genes coding for the structural and functional proteins that are indispensable for the payload to be packaged, (i.e. the helper phage provides all the necessary gene products for the assembly of the delivery vehicle). The helper phage may contain a defective origin of replication or packaging signal, or completely lack the latter, and hence it is incapable of self-packaging, thus only bacterial delivery particles carrying the payload or plasmid will be produced. Helper phages may be chosen so that they cannot induce lysis of the host used for the delivery particle production. One skilled in the art would understand that some bacteriophages are defective and need a helper phage for payload packaging. Thus, depending on the bacteriophage chosen to prepare the bacterial delivery particles, the person skilled in the art would know if a helper phage is required. Sequences coding for one or more proteins or regulatory processes necessary for the assembly or production of packaged payloads may be supplied in trans. For example, the STF, gpJ and gpH proteins of the present disclosure may be provided in a plasmid under the control of an inducible promoter or expressed constitutively. In this case, the phage wild-type sequence may or not contain a deletion of the gene or sequence supplied in trans. Additionally, chimeric or modified phage sequences encoding a new function, like an recombinant STF, gpJ or gpH protein, may be directly inserted into the desired position in the genome of the helper phage, hence bypassing the necessity of providing the modified sequence in trans. Methods for both supplying a sequence or protein in trans in the form of a plasmid, as well as methods to generate direct genomic insertions, modifications and mutations are well known to those skilled in the art. In a particular embodiment, said production cell line produces:
a STF protein which comprises or consists of the amino acid sequence of SEQ ID NO: 14 and its associated chaperone comprising or consisting of the amino acid sequence of SEQ ID NO: 15,
a STF protein which comprises or consists of the amino acid sequence of SEQ ID NO: 16,
a STF protein which comprises or consists of the amino acid sequence of SEQ ID NO: 17 and its associated chaperone comprising or consisting of the amino acid sequence of SEQ ID NO: 18,
a STF protein which comprises or consists of the amino acid sequence of SEQ ID NO: 19 and its associated chaperone comprising or consisting of the amino acid sequence of SEQ ID NO: 20,
a STF protein which comprises or consists of the amino acid sequence of SEQ ID NO: 21 and its associated chaperone comprising or consisting of the amino acid sequence of SEQ ID NO: 22,
a STF protein which comprises or consists of the amino acid sequence of SEQ ID NO: 44, or
a STF protein which comprises or consists of the amino acid sequence of SEQ ID NO: 50 and optionally its associated chaperone comprising or consisting of the amino acid sequence of SEQ ID NO: 57.
In a particular embodiment, said helper phage comprises a nucleic acid sequence encoding the chimeric RBP comprising or consisting of the sequence SEQ ID NO: 48, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 54, and said helper phase optionally further comprises a nucleic acid sequence encoding the chimeric gpJ variant comprising or consisting of the sequence SEQ ID NO: 13, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 27. In a particular embodiment, said helper phage is a lambda phage wherein (i) the nucleic acid encoding a wild-type STF protein has been replaced by a nucleic acid sequence encoding the chimeric RBP comprising or consisting of the sequence SEQ ID NO: 48, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 54, (ii) the nucleic acid encoding a wild-type gpJ protein has been replaced by a nucleic acid sequence encoding the chimeric gpJ variant comprising or consisting of the sequence SEQ ID NO: 13, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 27, and (iii) the Cos site has been removed, and wherein optionally (iv) the helper prophage contains a mutation which prevents spontaneous cell lysis, such as the Sam7 mutation and (v) the helper prophage contains a thermosensitive version of the master cI repressor, such as the c1857 version.
In an embodiment, the bacterial delivery vehicle disclosed herein comprises a DNA payload of interest. As used herein, the term “payload” refers to any nucleic acid sequence or amino acid sequence, or a combination of both (such as, without limitation, peptide nucleic acid or peptide-oligonucleotide conjugate) transferred into a bacterium with a delivery vehicle. The term “payload” may also refer to a plasmid, a vector or a cargo. The payload can be a phagemid or phasmid obtained from natural, evolved or engineered bacteriophage genome. The payload can also be composed only in part of phagemid or phasmid obtained from natural, evolved or engineered bacteriophage genome.
As shown in Example 1 below, the efficiency of loading of the payload by the bacterial delivery vehicle disclosed herein may depend upon the size of the payload, among others. Accordingly, in a particular embodiment, the payload has a size superior or equal to 4 kb, and preferably inferior or equal to 51 kb.
In said embodiment, the payload may have a size, an integer multiple of which is between 36 kb and 51 kb. In other words, in that embodiment, there is at least an integer n, such as 36 kb≤n×size of the payload≤51 kb.
It has been more particularly demonstrated that it was possible to produce a more uniform population of bacterial delivery vehicles comprising an almost unique number of payload copies when said payload had a size of a specific range.
In a particular embodiment, the payload has a size strictly superior to 10.000 kb and strictly inferior to 12.000 kb. In an alternative embodiment, the payload has a size strictly superior to 12.500 kb and strictly inferior to 16.667 kb, in particular a size strictly superior to 12.500 kb and inferior to 13.000 kb.
In another particular embodiment, the payload has a size superior or equal to 18.000 kb and inferior or equal to 25.000 kb, in particular inferior or equal to 24.000 kb.
The payload may be a nucleic acid plasmid that is able to circularize upon transfer into the target cell and then either replicate or integrate inside the chromosome. Replication of the vector DNA is dependent on the presence of a bacterial origin of replication. Once replicated, inheritance of the plasmid into each of the daughter cells can be mediated by the presence of an active partitioning mechanism and a plasmid addiction system such as toxin/anti-toxin system.
As used herein, the term “nucleic acid” refers to a sequence of at least two nucleotides covalently linked together which can be single-stranded or double-stranded or contains portion of both single-stranded and double-stranded sequence. Nucleic acids can be naturally occurring, recombinant or synthetic. The nucleic acid can be in the form of a circular sequence or a linear sequence or a combination of both forms. The nucleic acid can be DNA, both genomic or cDNA, or RNA or a combination of both. The nucleic acid may contain any combination of deoxyribonucleotides and ribonucleotides, and any combination of bases, including uracil, adenine, thymine, cytosine, guanine, inosine, xanthine, hypoxanthine, isocytosine, 5-hydroxymethylcytosine and isoguanine. Other examples of modified bases that can be used are detailed in Chemical Reviews 2016, 116 (20) 12655-12687. The term “nucleic acid” also encompasses any nucleic acid analogs which may contain other backbones comprising, without limitation, phosphoramide, phosphorothioate, phosphorodithioate, O-methylphosphoroamidite linkage and/or deoxyribonucleotides and ribonucleotides nucleic acids. Any combination of the above features of a nucleic acid is also encompassed by the present disclosure.
Origins of replication known in the art have been identified from species-specific plasmid DNAs (e.g. CoIE1, R1, pT181, pSC101, pMB1, R6K, RK2, p15a and the like), from bacterial virus (e.g. φX174, M13, F1 and P4) and from bacterial chromosomal origins of replication (e.g. oriC). In one embodiment, the phagemid according to the disclosure comprises a bacterial origin of replication that is functional in the targeted bacteria.
Alternatively, the plasmid according to the disclosure does not comprise any functional bacterial origin of replication or contain an origin of replication that is inactive in the targeted bacteria. Thus, the plasmid of the disclosure cannot replicate by itself once it has been introduced into a bacterium by the bacterial virus particle.
In one embodiment, the origin of replication on the plasmid to be packaged is inactive in the targeted bacteria, meaning that this origin of replication is not functional in the bacteria targeted by the bacterial virus particles, thus preventing unwanted plasmid replication.
In one embodiment, the plasmid comprises a bacterial origin of replication that is functional in the bacteria used for the production of the bacterial virus particles.
Plasmid replication depends on host enzymes and on plasmid-controlled cis and trans determinants. For example, some plasmids have determinants that are recognized in almost all gram-negative bacteria and act correctly in each host during replication initiation and regulation. Other plasmids possess this ability only in some bacteria (Kues, U and Stahl, U 1989 Microbiol Rev 53:491-516).
Plasmids are replicated by three general mechanisms, namely theta type, strand displacement, and rolling circle (reviewed by Del Solar et al. 1998 Microhio and Molec Biol. Rev 62:434-464) that start at the origin of replication. These replication origins contain sites that are required for interactions of plasmid and/or host encoded proteins.
Origins of replication used on the plasmid of the disclosure may be of moderate copy number, such as colE1 ori from pBR322 (15-20 copies per cell) or the R6K plasmid (15-20 copies per cell) or may be high copy number, e.g. pUC oris (500-700 copies per cell), pGEM oris (300-400 copies per cell), pTZ oris (>1000 copies per cell) or pBluescript oris (300-500 copies per cell).

In an embodiment, the bacterial origin of replication is selected in the group consisting of pC194, pE194, BBR1, pBC1, pEP2, pWVO1, pLF1311, pAP1, pWKS1, pLS1, pLS11, pUB6060, pJD4, pIJ101, pSN22, pAMbeta1, pIP501, pIP407, ZM6100(Sa), pCU1, RA3, pMOL98, RK2/RP4/RP1/R68, pB10, R300B, pRO1614, pRO1600, pECB2, pCM1, pFA3, RepFIA, RepFIB, RepFIC, pYVE439-80, R387, phasyl, RAL TF-FC2, pMV158 and pUB113.
In an embodiment, the bacterial origin of replication is ColE1.
The delivered nucleic acid sequence according to the disclosure may comprise a phage replication origin which can initiate, with complementation of a complete phage genome, the replication of the delivered nucleic acid sequence for later encapsulation into the different capsids.
A phage origin of replication comprised in the delivered nucleic acid sequence of the disclosure can be any origin of replication found in a phage.
In an embodiment, the phage origin of replication can be the wild-type or non-wild type sequence of the M13, f1, φX174, P4, lambda, P2, lambda-like, HK022, mEP237, HK97, HK629, HK630, mEP043, mEP213, mEP234, mEP390, mEP460, mEPx1, mEPx2, phi80, mEP234, T2, T4, T5, T7, RB49, phiX174, R17, PRD1 P1-like, P2-like, P22, P22-like, N15 and N15-like bacteriophages.
In an embodiment, the phage origin of replication is selected in the group consisting of phage origins of replication of M13, f1, φX174, P4, and lambda.
In a particular embodiment, the phage origin of replication is the lambda or P4 origin of replication.
The delivered nucleic acid of interest comprises a nucleic acid sequence under the control of a promoter. In certain embodiments, the nucleic acid of interest is selected from the group consisting of a Cas nuclease gene, a Cas9 nuclease gene, a guide RNA, a CRISPR locus, a toxin gene, a gene encoding an enzyme such as a nuclease or a kinase, a TALEN, a ZFN, a meganuclease, a recombinase, a bacterial receptor, a membrane protein, a structural protein, a secreted protein, a gene encoding resistance to an antibiotic or to a drug in general, a gene encoding a toxic protein or a toxic factor, and a gene encoding a virulence protein or a virulence factor, or any of their combination. In an embodiment, the nucleic acid payload encodes a therapeutic protein. In another embodiment, the nucleic acid payload encodes an antisense nucleic acid molecule.
In one embodiment, the sequence of interest is a programmable nuclease circuit to be delivered to the targeted bacteria. This programmable nuclease circuit is able to mediate in vivo sequence-specific elimination of bacteria that contain a target gene of interest (e.g. a gene that is harmful to humans). Some embodiments of the present disclosure relate to engineered variants of the Type II CRISPR-Cas (Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR-associated) system of Streptococcus pyogenes. Other programmable nucleases that can be used include other CRISPR-Cas systems, engineered TALEN (Transcription Activator-Like Effector Nuclease) variants, engineered zinc finger nuclease (ZFN) variants, natural, evolved or engineered meganuclease or recombinase variants, and any combination or hybrids of programmable nucleases. Thus, the engineered autonomously distributed nuclease circuits provided herein may be used to selectively cleave DNA encoding a gene of interest such as, for example, a toxin gene, a virulence factor gene, an antibiotic resistance gene, a remodeling gene or a modulatory gene (cf. WO2014124226).
Other sequences of interest, such as programmable sequences, can be added to the delivered nucleic acid sequence so as to be delivered to targeted bacteria. In an embodiment, the sequence of interest added to the delivered nucleic acid sequence leads to cell death of the targeted bacteria. For example, the nucleic acid sequence of interest added to the plasmid may encode holins or toxins.
Alternatively, the sequence of interest circuit added to the delivered nucleic acid sequence does not lead to bacteria death. For example, the sequence of interest may encode reporter genes leading to a luminescence or fluorescence signal. Alternatively, the sequence of interest may comprise proteins and enzymes achieving a useful function such as modifying the metabolism of the bacteria or the composition of its environment.
In a particular embodiment, the nucleic sequence of interest is selected in the group consisting of Cas9, a single guide RNA (sgRNA), a CRISPR locus, a gene encoding an enzyme such as a nuclease or a kinase, a TALEN, a ZFN, a meganuclease, a recombinase, a bacterial receptor, a membrane protein, a structural protein, a secreted protein, a gene encoding resistance to an antibiotic or to a drug in general, a gene encoding a toxic protein or a toxic factor and a gene encoding a virulence protein or a virulence factor.

Bacteriocins are categorized in several ways, including producing strain, common resistance mechanisms, and mechanism of killing. Such bacteriocin had been described from gram negative bacteria (e.g. microcins, colicin-like bacteriocins and tailocins) and from gram positive bacteria (e.g. Class I, Class II, Class III or Class IV bacteriocins).
In one embodiment, the delivered nucleic acid sequence according to the disclosure further comprises a sequence of interest encoding a toxin selected in the group consisting of microcins, colicin-like bacteriocins, tailocins, Class I, Class II, Class III and Class IV bacteriocins.
In a particular embodiment, the corresponding immunity polypeptide (i.e. anti-toxin) may be used to protect bacterial cells (see review by Cotter et al., Nature Reviews Microbiology 11: 95, 2013, which is hereby incorporated by reference in its entirety) for delivered nucleic acid sequence production and encapsidation purpose but is absent in the pharmaceutical composition and in the targeted bacteria in which the delivered nucleic acid sequence of the disclosure is delivered.
In one aspect of the disclosure, the CRISPR system is included in the delivered nucleic acid sequence. The CRISPR system contains two distinct elements, i.e. i) an endonuclease, in this case the CRISPR associated nuclease (Cas or “CRISPR associated protein”) and ii) a guide RNA. The guide RNA is in the form of a chimeric RNA which consists of the combination of a CRISPR (RNAcr) bacterial RNA and a RNAtracr (trans-activating RNA CRISPR) (Jinek et al., Science 2012). The guide RNA combines the targeting specificity of the RNAcr corresponding to the “spacing sequences” that serve as guides to the Cas proteins, and the conformational properties of the RNAtracr in a single transcript. When the guide RNA and the Cas protein are expressed simultaneously in the cell, the target genomic sequence can be permanently modified or interrupted. The modification is advantageously guided by a repair matrix. In general, the CRISPR system includes two main classes depending on the nuclease mechanism of action. Class 1 is made of multi-subunit effector complexes and includes type I, III and IV. Class 2 is made of single-unit effector modules, like Cas9 nuclease, and includes type II (II-A, II-B, II-C, II-C variant), V (V-A, V-B, V-C, V-D, V-E, V-U1, V-U2, V-U3, V-U4, V-U5) and VI (VI-A, VI-B1, VI-B2, VI-C, VI-D)
The sequence of interest according to the present disclosure comprises a nucleic acid sequence encoding Cas protein. A variety of CRISPR enzymes are available for use as a sequence of interest on the plasmid. In some embodiments, the CRISPR enzyme is a Type II CRISPR enzyme. In some embodiments, the CRISPR enzyme catalyzes DNA cleavage. In some other embodiments, the CRISPR enzyme catalyzes RNA cleavage. In one embodiment, the CRISPR enzymes may be coupled to a sgRNA. In certain embodiments, the sgRNA targets a gene selected in the group consisting of an antibiotic resistance gene, virulence protein or factor gene, toxin protein or factor gene, a bacterial receptor gene, a membrane protein gene, a structural protein gene, a secreted protein gene and a gene encoding resistance to a drug in general.
Non-limiting examples of Cas proteins as part of a multi-subunit effector or as a single-unit effector include Cas1, Cas1B, Cas2, Cas3, Cas4, Cas5, Cash, Cas7, Cas8, Cas9 (also known as Csn1 and Csx12), Cas10, Cas11 (SS), Cas12a (Cpf1), Cas12b (C2c1), Cas12c (C2c3), Cas12d (CasY), Cas12e (CasX), C2c4, C2c8, C2c5, C2c10, C2c9, Cas13a (C2c2), Cas13b (C2c6), Cas13c (C2c7), Cas13d, Csa5, Csc1, Csc2, Cse1, Cse2, Csy1, Csy2, Csy3, Csf1, Csf2, Csf3, Csf4, Csm2, Csm3, Csm4, Csm5, Csm6, Cmr1, Cmr3, Cmr4, Cmr5, Cmr6, Csn2, Csb1, Csb2, Csb3, Csx17, Csx14, Csx10, Csx16, CsaX, Csx13, Csx1, Csx15, SdCpf1, CmtCpf1, TsCpf1, CmaCpf1, PcCpf1, ErCpf1, FbCpf1, UbcCpf1, AsCpf1, LbCpf1, homologues thereof, orthologues thereof, variants thereof, or modified versions thereof. In some embodiments, the CRISPR enzyme cleaves both strands of the target nucleic acid at the Protospacer Adjacent Motif (PAM) site.
In a particular embodiment, the CRISPR enzyme is any Cas9 protein, for instance any naturally occurring bacterial Cas9 as well as any variants, homologs or orthologs thereof.
By “Cas9” is meant a protein Cas9 (also called Csn1 or Csx12) or a functional protein, peptide or polypeptide fragment thereof, i.e. capable of interacting with the guide RNA(s) and of exerting the enzymatic activity (nuclease) which allows it to perform the double-strand cleavage of the DNA of the target genome. “Cas9” can thus denote a modified protein, for example truncated to remove domains of the protein that are not essential for the predefined functions of the protein, in particular the domains that are not necessary for interaction with the gRNA (s).
The sequence encoding Cas9 (the entire protein or a fragment thereof) as used in the context of the disclosure can be obtained from any known Cas9 protein (Fonfara et al., Nucleic Acids Res 42 (4), 2014; Koonin et al., Nat Rev Microbiol 15(3), 2017).

Examples of Cpf1(Cas12a) proteins useful in the present disclosure include, but are not limited to, Cpf1(Cas12a) proteins of Acidaminococcus sp, Lachnospiraceae bacteriu and Francisella novicida.
The sequence encoding Cas13a (the entire protein or a fragment thereof) can be obtained from any known Cas13a (C2c2) protein (Abudayyeh et al., 2017). Examples of Cas13a (C2c2) proteins useful in the present disclosure include, but are not limited to, Cas13a (C2c2) proteins of Leptotrichia wadei (LwaCas13a).
The sequence encoding Cas13d (the entire protein or a fragment thereof) can be obtained from any known Cas13d protein (Yan et al., 2018). Examples of Cas13d proteins useful in the present disclosure include, but are not limited to, Cas13d proteins of Eubacterium siraeum and Ruminococcus sp.
In a particular embodiment, the nucleic sequence of interest is a CRISPR/Cas9 system for the reduction of gene expression or inactivation a gene selected in the group consisting of an antibiotic resistance gene, virulence factor or protein gene, toxin factor or protein gene, a gene encoding a bacterial receptor, a membrane protein, a structural protein, a secreted protein, and a gene encoding resistance to a drug in general.
In one embodiment, the CRISPR system is used to target and inactivate a virulence factor. A virulence factor can be any substance produced by a pathogen that alters host-pathogen interaction by increasing the degree of damage done to the host. Virulence factors are used by pathogens in many ways, including, for example, in cell adhesion or colonization of a niche in the host, to evade the host's immune response, to facilitate entry to and egress from host cells, to obtain nutrition from the host, or to inhibit other physiological processes in the host. Virulence factors can include enzymes, endotoxins, adhesion factors, motility factors, factors involved in complement evasion, and factors that promote biofilm formation. For example, such targeted virulence factor gene can be E. coli virulence factor gene such as, without limitation, EHEC-HlyA, Stx1 (VT1), Stx2 (VT2), Stx2a (VT2a), Stx2b (VT2b), Stx2c (VT2c), Stx2d (VT2d), Stx2e (VT2e) and Stx2f (VT2f), Stx2h (VT2h), fimA, fimF, fimH, neuC, kpsE, sfa, foc, iroN, aer, iha, papC, papGI, papGII, papGIII, hlyC, cnf1, hra, sat, ireA, usp ompT, ibeA, malX, fyuA, irp2, traT, afaD, ipaH, eltB, estA, bfpA, eaeA, espA, aaiC, aatA, TEM, CTX, SHV, csgA, csgB, csgC, csgD, csgE, csgF, csgG, csgH, T1SS, T2SS, T3SS, T4SS, T5SS, T6SS (secretion systems).

In another embodiment, the CRISPR/Cas9 system is used to target and inactivate a bacterial toxin gene. Bacterial toxins can be classified as either exotoxins or endotoxins. Exotoxins are generated and actively secreted; endotoxins remain part of the bacteria. The response to a bacterial toxin can involve severe inflammation and can lead to sepsis. Such toxin can be for example Botulinum neurotoxin, Tetanus toxin, Staphylococus toxins, Diphteria toxin, Anthrax toxin, Alpha toxin, Pertussis toxin, Shiga toxin, Heat-stable enterotoxin (E. coli ST), colibactin, BFT (B. fragilis toxin) or any toxin described in Henkel et al., (Toxins from Bacteria in EXS. 2010; 100: 1-29).
In a particular embodiment, said payload comprises or consists of the nucleic acid sequence SEQ ID NO: 47.
The bacteria targeted by bacterial delivery vehicles disclosed herein can be any bacteria present in a mammal organism. In a certain aspect, the bacteria are targeted through interaction of the chimeric RBPs and/or the branched-RBPs expressed by the delivery vehicles with the bacterial cell. It can be any commensal, symbiotic or pathogenic bacteria of the microbiota or microbiome.
A microbiome may comprise a variety of endogenous bacterial species, any of which may be targeted in accordance with the present disclosure. In some embodiments, the genus and/or species of targeted endogenous bacterial cells may depend on the type of bacteriophages being used for preparing the bacterial delivery vehicles. For example, some bacteriophages exhibit tropism for, or preferentially target, specific host species of bacteria. Other bacteriophages do not exhibit such tropism and may be used to target a number of different genus and/or species of endogenous bacterial cells.
Examples of bacterial cells include, without limitation, cells from bacteria of the genus Yersinia spp., Escherichia spp., Klebsiella spp., Acinetobacter spp., Bordetella spp., Neisseria spp., Aeromonas spp., Franciesella spp., Corynebacterium spp., Citrobacter spp., Chlamydia spp., Hemophilus spp., Brucella spp., Mycobacterium spp., Legionella spp., Rhodococcus spp., Pseudomonas spp., Helicobacter spp., Vibrio spp., Bacillus spp., Erysipelothrix spp., Salmonella spp., Streptomyces spp., Streptococcus spp., Staphylococcus spp., Bacteroides spp., Prevotella spp., Clostridium spp., Bifidobacterium spp., Clostridium spp., Brevibacterium spp., Lactococcus spp., Leuconostoc spp., Actinobacillus spp., Selnomonas spp., Shigella spp., Zymonas spp., Mycoplasma spp., Treponema spp., Leuconostoc spp., Corynebacterium spp., Enterococcus spp., Enterobacter spp., Pyrococcus spp., Serratia spp., Morganella spp., Parvimonas spp., Fusobacterium spp., Actinomyces spp., Porphyromonas spp., Micrococcus spp., Bartonella spp., Borrelia spp., Brucelia spp., Campylobacter spp., Chlamydophilia spp., Cutibacterium (formerly Propionibacterium) spp., Ehrlichia spp., Haemophilus spp., Leptospira spp., Listeria spp., Mycoplasma spp., Nocardia spp., Rickettsia spp., Ureaplasma spp., and Lactobacillus spp, and a mixture thereof.

Suitable examples of liquid vehicles for oral and enteral administration include water (partially containing additives as above, e.g. cellulose derivatives, preferably sodium carboxymethyl cellulose solution), alcohols (including monohydric alcohols and polyhydric alcohols, e.g. glycols) and their derivatives, and oils (e.g. fractionated coconut oil and arachis oil). For parenteral administration, the vehicle can also be an oily ester such as ethyl oleate and isopropyl myristate. Sterile liquid vehicles are useful in sterile liquid form compositions for enteral administration. The liquid vehicle for pressurized compositions can be a halogenated hydrocarbon or other pharmaceutically acceptable propellant.
For transdermal administration, the pharmaceutical or veterinary composition can be formulated into ointment, cream or gel form and appropriate penetrants or detergents could be used to facilitate permeation, such as dimethyl sulfoxide, dimethyl acetamide and dimethylformamide.
For transmucosal administration, nasal sprays, rectal or vaginal suppositories can be used. The active compounds can be incorporated into any of the known suppository bases by methods known in the art. Examples of such bases include cocoa butter, polyethylene glycols (carbowaxes), polyethylene sorbitan monostearate, and mixtures of these with other compatible materials to modify the melting point or dissolution rate.
The diseases or disorders caused by bacteria may be selected from the group consisting of abdominal cramps, acne vulgaris, acute epiglottitis, arthritis, bacteraemia, bloody diarrhea, botulism, Brucellosis, brain abscess, chancroid venereal disease, Chlamydia, Crohn's disease, conjunctivitis, cholecystitis, colorectal cancer, polyposis, dysbiosis, Lyme disease, diarrhea, diphtheria, duodenal ulcers, endocarditis, erysipelothricosis, enteric fever, fever, glomerulonephritis, gastroenteritis, gastric ulcers, Guillain-Barre syndrome tetanus, gonorrhoea, gingivitis, inflammatory bowel diseases, irritable bowel syndrome, leptospirosis, leprosy, listeriosis, tuberculosis, Lady Widermere syndrome, Legionaire's disease, meningitis, mucopurulent conjunctivitis, multi-drug resistant bacterial infections, multi-drug resistant bacterial carriage, myonecrosis-gas gangrene, Mycobacterium avium complex, neonatal necrotizing enterocolitis, nocardiosis, nosocomial infection, otitis, periodontitis, phalyngitis, pneumonia, peritonitis, purpuric fever, Rocky Mountain spotted fever, shigellosis, syphilis, sinusitis, sigmoiditis, septicaemia, subcutaneous abscesses, tularaemia, tracheobronchitis, tonsillitis, typhoid fever, ulcerative colitis, urinary infection, whooping cough.
The disease or disorder caused by bacteria may be a bacterial infection selected from the group consisting of skin infections such as acne, intestinal infections such as esophagitis, gastritis, enteritis, colitis, sigmoiditis, rectitis, and peritonitis, urinary tract infections, vaginal infections, female upper genital tract infections such as salpingitis, endometritis, oophoritis, myometritis, parametritis and infection in the pelvic peritoneum, respiratory tract infections such as pneumonia, intra-amniotic infections, odontogenic infections, endodontic infections, fibrosis, meningitis, bloodstream infections, nosocomial infection such as catheter-related infections, hospital acquired pneumonia, post-partum infection, hospital acquired gastroenteritis, hospital acquired urinary tract infections, and a combination thereof. In an embodiment, the infection according to the disclosure is caused by a bacterium presenting an antibiotic resistance. In a particular embodiment, the infection is caused by a bacterium as listed above in the targeted bacteria. In another embodiment, the infection according to the disclosure is caused by a bacterium expressing toxin, such as shiga-toxin. In a particular embodiment, the infection is caused by a Shiga-Toxin producing E. coli (STEC).
The disease or disorder caused by bacteria may also be a metabolic disorder, for example, obesity and/or diabetes.

In an embodiment, the biological sample comprises pathological and non-pathological bacterial species, and subsequent to administering the pharmaceutical or veterinary composition according to the disclosure to the individual, the amount of pathogenic bacteria on or in the individual are reduced, but the amount of non-pathogenic bacteria is not reduced.
In another particular embodiment, the disclosure concerns a pharmaceutical or veterinary composition according to the disclosure for use to improve the effectiveness of drugs. Indeed, some bacteria of the microbiome, without being pathogenic by themselves, are known to be able to metabolize drugs and to modify them in ineffective or harmful molecules.
In another particular embodiment, the disclosure concerns a composition that may further comprise at least one additional active ingredient, for instance a prebiotic and/or a probiotic and/or an antibiotic, and/or another antibacterial or antibiofilm agent, and/or any agent enhancing the targeting of the bacterial delivery vehicle to a bacteria and/or the delivery of the payload into a bacteria.

The present disclosure also relates to a non-therapeutic use of the bacterial delivery particles. For instance, the non-therapeutic use can be a cosmetic use or a use for improving the well-being of a subject, in particular a subject who does not suffer from a disease. Accordingly, the present disclosure also relates to a cosmetic composition or a non-therapeutic composition comprising the bacterial delivery particles of the disclosure.
The present disclosure will be further illustrated by the examples below.
Lambda-packaged cosmids are derived from lambda PaPa, a variant of the wild-type Ur-lambda phage with a frameshift mutation in the stf gene [7] leading to a truncated protein which is an inactive STF protein, i.e a protein with no biological activity. Lambda Papa has been used as the de facto wild-type lambda phage in the majority of laboratory studies, because as opposed to wild-type Ur-lambda, it makes larger plaques that are easier to handle. The stf gene codes for the side tail fiber protein, which in the case of phage lambda recognizes the secondary receptor on the cell surface, OmpC.
This secondary receptor allows for transient binding of the phage particle on the cell surface in order to scan the surface and position the injection machinery in contact with the primary receptor (LamB in the case of lambda, interaction mediated by the lambda protein gpJ). Since the STF binding is reversible, it allows the phage to “walk” on the cell surface until a primary receptor is found and the infection process starts. These protein complexes are sometimes referred to as “L-shape fibers”, such as in T5, “side tail fibers” such as in lambda, “long tail fibers” as in T4, or tailspikes such as in phage P22 [7]-[10]. For some phages, the presence of this second set of proteins is necessary for the infection process to occur, such as T4 [8]. In some other phages, like lambda, this second set of proteins is not necessary for the infection process to happen, but it may allow for a more efficient attachment to the target cell [7].
The wild-type length of the lambda phage genome is 48.5 kbp. It is well known that lambda can only package DNA from 37.7 kbp to 51 kbp [11], or about 78% to 105% of the wild-type length. Smaller DNA payloads do not build up enough pressure inside the capsid for packaging termination to occur and larger ones make the capsid too unstable. Additionally, smaller genomes have been shown to be ejected with much lower efficiency in the presence of higher external osmotic pressures [12]: as the length of the encapsidated DNA decreases, the ejection force decreases in an exponential fashion between the two size extremes 37.7 to 51 kbp. It is also known that the smaller the payload is, the lower the efficiency at which packaged particles will form [11]. Combining these two observations, it can be concluded that a smaller DNA payload will be detrimental if high enough titers for in vivo experiments are needed.
Most of the phagemids packaged using the lambda system (and many others) are much smaller than the wild-type length of the phage. Packaging is possible because the cosmid forms concatemers via the sigma replication pathway: when the concatemers fall between 74% and 105% of the wild-type lambda genome length, packaging is terminated and a mature packaged cosmid is formed [11]. This means that these particles, in contrast to a wild-type lambda genome, will not have packaged DNA of a homogeneous length: the whole range of 74% to 105% genome lengths will be present. For example, in [11] a cosmid of 12.8 kb was shown to be packaged as trimers and tetramers, which correspond to 38.4 kb and 51.2 kb (in the range of allowed packaged sizes); the 38.4 kb variant was found in about 15% of the particles while the 51.2 kb was found in about 40%. Similarly, a 4.6 kb plasmid was shown to be packaged as a 9-mer, 10-mer and 11-mer (41.4 kb, 46 kb and 50.6 kb). In this case, the 41 kb variant was the most common with about 20% of the particles having this size, followed by the 50.6 kb variant with about 12%; the 46 kb variant was only present in about 5% of the particles.
For in vivo applications, such as oral delivery of encapsidated DNA particles, packaged phagemids will need to be given at high enough concentrations to reach all the target cells; hence, a payload that gives high enough titers is essential to optimize the in vivo activity as well as the manufacturing process.
Finally, besides a payload with a proper size, the packaged particle needs to be able to bind its target cell strongly and long enough for the injection process to occur. It was previously shown that the presence of STF is not necessary for lambda-mediated in vitro transduction experiments in K-12 laboratory strains [7].
Here, it has been unexpectedly shown that both a suitable payload that is packaged as concatemers of the correct length as well as a functional side tail fiber greatly increase efficiency when performing in vivo delivery assays of lambda-based packaged phagemids. It has also unexpectedly demonstrated herein that for strains other than model K12 strains, STF and/or gpJ from other phages that can specifically recognize surface antigens/receptors of the target bacteria can be used to generate engineered lambda viral particles that mediate efficient delivery both in vitro and in vivo.
A mouse model, using E. coli strain MG1655, or derivatives, with engineered streptomycin resistance was developed using an established colonization protocol [13]. Mice (Balb/c ByJ, 7 weeks) were treated with a short course of streptomycin, which is known to reduce the natural coliform intestinal population [14]. This treatment allows for exogenous E. coli to be administered and colonize empty ecological niches while maintaining other species that are present in the natural microbiota. In detail, animals were treated with a 5-day course of 5 g/L streptomycin in drinking water. The treatment was stopped 5 days before gavaging of the packaged phagemids to avoid any bias and selection of resistance due to antibiotic evolutionary pressure.
To test the in vivo delivery efficiency of packaged phagemids, psgRNAcos, the 2.5 kb cosmid of SEQ ID NO: 1 carrying a kanamycin resistance gene was packaged into lambda PaPa particles, encoding a non-functional stf gene. To achieve this, the cosmid was transformed in an E. coli strain carrying the lambda prophage lacking a cos site but otherwise possessing all the machinery for the induction of the lambda phage lytic cycle as well as the DNA packaging system. The cI repressor of the lambda prophage carries mutations making it thermosensitive and enabling the induction of the lytic cycle through temperature change. The cells containing the lambda cosmid were grown at 30° C. in liquid LB media. At an OD600 of 0.6, the culture was shifted to 42° C. for 25 minutes to induce the entry into lytic cycle. After that, cells were shifted back to 37° C. for 3 hours to allow for virion assembly containing the lambda cosmid. Cells were then centrifuged and washed in lambda buffer (10 mM Tris pH 7.5, 100 mM NaCl, 10 mM MgSO4). Chloroform was added and the sample was spun down at 17,000 g for 5 minutes. Finally, the aqueous phase was collected and filtered through a 0.2 μm pore-size filter. The titer of the packaged phagemids was measured by performing a transduction assay in vitro using strain MG-GFP as a recipient. MG-GFP is a derivative of strain MG1655 with a gfp fluorescent reporter gene and an ampicillin resistance gene inserted in the chromosome. The titer was determined to be about 106 particles/μl (not shown). This packaged phagemid stock was used to transduce strain MG-GFP in the gut of mice colonized by MG-GFP for 5 days. Feces were collected at different time points, homogenized and plated on LB agar plates with kanamycin to monitor the number of transduced MG-GFP cells. Kanamycin-resistant colonies were counted in different parts of the mice intestinal tract (psgRNAcos encodes a kanamycin marker). As depicted in
The low delivery efficiencies observed are consistent with the fact that the lambda PaPa phage replicates very poorly in the gut of mice colonized by MG-GFP, as measured by counting plaque forming units over time in the feces of mice colonized by MG-GFP and infected with lambda PaPa. To identify the reason for this poor efficiency of lambda PaPa in the mouse gut, an in vivo evolution assay was performed to select improved variants of this phage. Mice colonized by MG-GFP were gavaged with an initial total dose of 107 lambda PaPa. Every day, faeces were collected and tested for their ability to form plaques on lawns of MG1655. They were also homogenized in 1×PBS at 40 mg/mL, filtered through a 0.22 μm pore membrane and re-fed to the mice. As can be seen in
Strikingly, when the genomes of the phage particles obtained on day 35 were sequenced, it was observed that the ORF of the stf gene had been restored: the lambda PaPa particles had reverted the mutation to give a full-length stf gene (although with mutations in K338E, T391M and A395S with respect to the canonical STF sequence of SEQ ID NO: 14). Additionally, it was observed that the gpJ gene, responsible for binding to the LamB receptor, had also mutated in three positions. These mutations were tested to determine if they altered the receptor being used by this phage on wild-type MG1655 and MG1655-delta-LamB. No difference was observed, which confirmed that the new Ur-lambda particles still use LamB as their primary receptor.
With the ORF of the stf gene restored in the original lambda packaged phagemid production strain, but keeping the original STF sequence of SEQ ID NO: 14 and not the mutated version obtained in the experiment above, the same experiment was performed with a packaged phagemid containing a DNA payload of 3 kb in size (pJ23104-GFP of SEQ ID NO: 2) but this time encoding a chloramphenicol marker. The sequence of the gpJ gene was not changed at this stage. The packaged phagemids were gavaged to mice colonized with MG1655-Strp (with streptomycin resistance). Feces were homogenized at 40 mg/mL in 1×PBS and serially diluted and plated in Drigalski plates supplemented or not with 25 μg/mL chloramphenicol. The amount of chloramphenicol resistant cells was hence counted in the faeces up to 48 h after transduction. As can be seen in
An experiment was then done in which a packaged phagemid was produced with a larger DNA payload, pJF1 of SEQ ID NO: 3 (around 7 kb) in Ur-lambda capsids and administered to the mice. It is important to note that the gpJ gene was not changed, so these particles encode the wild-type gpJ lambda of SEQ ID NO: 10 and still use LamB as their primary receptor. The same protocol was followed for in vivo delivery as for the smaller DNA payload of SEQ ID NO: 2. Surprisingly, as can be seen in
Since strong differences were observed depending on the size of the DNA payload used, a set of experiments were performed where DNA payload of different sizes of SEQ ID NO: 4 to 8 were packaged into lambda capsids delivery vehicles and their titers assessed before the in vivo assays. The production was carried out in the same conditions for all payloads. After production and lysis following the protocol mentioned above, a step of TFF filtration with a 100 kDa pore size was carried out on the cleared lysates, and buffer exchanged for 1×PBS. The TFF step allows for the concentration of the particles about 1 log compared to the cleared lysates. As can be seen in
Finally, to verify the roles of DNA payload size, titers and STF presence, the 6 kb and 8 kb variants (GG6K of SEQ ID NO: 6 and GG8K of SEQ ID NO: 7, respectively) shown in
Significantly, these results highlight the importance of a functional STF in in vivo conditions, which does not reflect the results obtained in vitro, where no obvious difference can be observed using lambda Papa or Ur-lambda packaged phagemids by plating.
This set of experiments brings three conclusions that have a major impact for the development of a successful approach to use packaged phagemids in vivo, especially for decolonization purposes. First, a DNA payload with a proper size to obtain high enough titers is necessary. If the DNA payload is too small, an intensive downstream processing focused on concentration of the particles to suitable titers must be put in place, which may slow down the production process and increase its cost. Second, the presence of a functional STF is essential to obtain the high delivery efficiencies needed for in vivo experiments, and it has been previously shown that STF can be engineered for each target strain (see for instance US provisional application U.S. 62/802,777, U.S. application Ser. No. 16/696,769 and U.S. application Ser. No. 16/726,033 each of which is incorporated by reference in their entirety). Third, the primary receptor, LamB in this case, may not be optimal for the pursued application. As described below, it is shown that one can engineer phagemid particles to include gpJ variants (in the case of lambda) that bind other receptors than LamB.
The lambda phage uses the bacterial LamB OMP as its main entry receptor [15], which is recognized by the gpJ protein situated at the tip of the phage particle. This event triggers DNA ejection into the bacterial cytoplasm and is usually viewed as an “irreversible” binding process [15]. However, a bacterial strain can become resistant to lambda phage entry if the LamB receptor is mutated, masked or downregulated; in particular, downregulation of the LamB gene has been observed for MG1655 strains in some mouse models, and this downregulation is caused by genotypic change: a mutation in the malT gene, regulating LamB expression levels, causes a drastic decrease in the number of these receptors in the membrane [16], [17]. In turn, bacteriophages have evolved different strategies to bypass these defense mechanisms. For instance, mutating the gpJ protein allows them to use a different receptor [18], [19]. It is also known that the receptor-recognition activity of gpJ lies in its C-terminal part, with a fragment as small as 249 aa conferring the capability of binding to LamB receptors [5].
Therefore, having different combinations of STF and gpJ that allow entry in specific conditions or different bacterial strains is crucial for the successful utilization of lambda-derived packaged phagemids as therapeutic agents, especially for in vivo applications. For this reason, several gpJ chimeras have been engineered that recognize receptors other than LamB, as well as identified variants that allow entry in some E. coli strains but not others.
To achieve this, gpJ homologs from different E. coli prophage genomes were searched and a protein alignment to find the areas in the C-terminal part that may be involved in recognizing the bacterial OMP receptor was performed (
As shown in
In the light of these results, it seems that the approach of generating gpJ chimeras can produce not only variants that recognize different OMPs in the same strain, but also variants that show different strain specificity.
However, changing the primary receptor is a futile effort if the strain is encapsulated: since the packaged phagemid will not have access to the receptor due to a physical masking of the cell surface, the delivery efficiency will be drastically reduced. It is for this reason that for the activity tests of the gpJ fusions shown above, the naked H10-waaJ O157 strain was used, since it is known that O157 strains produce a group IV capsular antigen that masks the cellular surface [21]. In this case, a combination of a functional STF and gpJ is necessary to obtain high delivery efficiencies.
To do this, stf and the tfa (chaperone) genes from the lambda prophage in the production strain were seamlessly deleted. Chimeric stfs were then complemented in trans with a plasmid carrying DAPG-inducible versions of these chimeric stfs. Indeed, when using a STF variant referred to as WW11.2 and represented by SEQ ID NO: 16 that shows specificity for the O157 antigen, in combination with the gpJ variant Z2145 of amino acid sequence SEQ ID NO: 12 shown above, very efficient entry in encapsulated O157 strain were obtained, as can be seen in
Additionally, it has been shown that another possible mechanism for bacteria to protect from phage injection is the mutation of periplasmic proteins that are believed to assist in the formation of a channel across the periplasm while the DNA is being injected [22]-[24]. Lambda phage can regain its activity in these mutants by modifying the gpH gene, the tape measure protein, although the exact position of these mutations is not known. In the lambda phage, the protein involved in the interaction with the mannose permease complex is gpH. Recently, it has been described that some E. coli strains become resistant to infection by HK97, a lambdoïd phage, by mutations in the glucose transporter protein PtsG; the gpH protein of HK97 is inhibited and injection into these mutants cannot occur. The authors describe that by changing a region of the gpH protein in the HK97 phage they could bypass the PtsG mutation and the engineered HK97 becomes infectious again.
To test if this hypothesis is generalizable to the lambda phage, alignments of the lambda gpH protein to other lambdoïd prophages present in E. coli was performed. As shown in
The gpH gene was modified in the lambda packaged phagemid production strain, as was done for the gpJ variants, to include both variable regions and packaged phagemids were produced as described above. This gpH variant of SEQ ID NO: 24 was termed gpH-IAI. In this case, three strains were used for titration: MG1655, KEIO manY and KEIO manZ, which contain deletions of two components of the mannose permease complex. As can be seen in
With this battery of experiments, it is shown that one is able to engineer the three main mechanisms involved in lambdoïd phage recognition and injection into its host: capsule/secondary receptor (through STF); primary receptor recognition (through gpJ); and permease/periplasmic channel formation (through gpH). These modifications can be used to engineer lambdoïd phages and packaged phagemids with modified tropism and injection efficiency in a wide number of E. coli strains.
Finally, it has been shown that lambdoïd-derived packaged phagemids can be used to deliver in other Proteobacteria different from E. coli, such as Klebsiella, Agrobacterium, or Pseudomonas. [25]-[27]. However, this approach requires the transformation of the receiver strains with a plasmid encoding the E. coli LamB receptor, since other species do not possess it. While this is a valid approach for cells grown in laboratory conditions, it becomes infeasible if bacteria present in natural conditions are to be targeted with lambda-derived packaged phagemids (for instance, the gut), since the plasmid encoding the receptor cannot be easily transferred.
It was tested if the lambda-derived packaged phagemids could be used to deliver the p7.3 kb payload of SEQ ID NO: 9 to other Proteobacteria, such as Enterobacter. To achieve this, different lambda packaged phagemids were engineered to contain several combinations of gpJ, Z2145 of SEQ ID NO: 12 and 1A2 of SEQ ID NO: 13 and, STF variants STF-EB6 of SEQ ID NO: 19 (with its chaperone (or accessory) protein of SEQ ID NO: 20), STF75 of SEQ ID NO: 17 (with its accessory protein of SEQ ID NO: 18) and STF23 of SEQ ID NO: 21 (with its accessory protein of SEQ ID NO: 22).
These results show that injection elements of the lambda capsid (gpJ, stf, gpH) can be engineered to achieve high delivery efficiency in other type of bacteria than E. coli. Accordingly, the present example shows that it is advantageous to use one or more of these approaches (DNA payload size optimization and selection of a proper gpJ/STF/gpH combination) to generate optimized lambdoïd-based delivery vehicles to be used in in vivo experiments involving transfer of DNA.
Tests were conducted to determine if a payload inside packaged phagemids with lambda STF fusions based on homology points could be delivered to bacteria in the gastrointestinal tract of a host without such STF being affected by proteolytic activity present in the gastrointestinal tract, in particular by pancreatin (i.e. low to no delivery of the payload to bacteria).
In principle, the structure of homology-based STF chimeras should be reminiscent of the original proteins, as the amino acid sequence of the fusion points has not been majorly modified. This means that if the original STFs had evolved to be pancreatin resistant, it is quite probable that the chimera will also be resistant. To prove this, two different STF chimeras with lambda STF functional when targeting LMR_503 strain (lambda-STF29, SEQ ID NO: 63 with its accessory protein of sequence SEQ ID NO: 65; and lambda-STF118, SEQ ID NO: 64 with its accessory protein of sequence SEQ ID NO: 66) were engineered. The insertion point of STF29 is ADAKKS (SEQ ID NO: 38) and the insertion point of STF118 is MDETNR (SEQ ID NO: 39). Eligobiotics® harboring the 1A2 gpJ and each of the STF chimeras were produced and titrated on MG1656-OmpCO157 or LMR 503 after treatment with or without pancreatin at pH 6.8. Briefly, the readout strain for chimeric STF activity is LMR 503 and the readout for gpJ activity is MG1656-OmpCO157. As can be seen in
To evaluate the effect of DNA payload size on the number of payloads packaged in Eligobiotics® (EB), 3 different payloads were used to produce Eligobiotics® as summarized in Table 1.
After fermentation, lysis (3 h incubation at 37° C. with 0.1% Triton X-100, 2000 U/L Benzonase) and clarification on a Zeta Plus Capsule (3M), Eligobiotics® were purified by anion exchange chromatography on a Sartobind Q capsule (Sartorius). This initial purification was followed by a buffer exchange and concentration step by tangential flow filtration on a Pellicon 2 minicassette Biomax 300 kDa (Millipore). A final polishing step of size exclusion chromatography on Sepharose 6FF resin (GE Healthcare) was performed to yield the purified Eligobiotics.
Analysis of Eligobiotics® DNA content was performed by analytical ultracentrifugation in a Beckman Coulter Optima AUC using an AN50Ti rotor at 6 krpm. The sedimentation coefficients of different EBs present in solution for each EB batch were extracted from sedimentation velocity data (acquired at 260 and 280 nm).
Based on the molecular weight calculated from their sedimentation coefficient and their 260/280 nm ratios, the different populations of EBs detected could be separated as Eligobiotics® containing either 3 copies (centered on 290 S) or 4 copies (centered on 330-340 S) of the payload (
Important differences were observed between Eligobiotics® depending on the size of the packaged payload. Although Eligobiotics® packaging the smaller p1392 (11.615 kb) yielded almost exclusively particles containing 4 copies of the payload, small increases (up to 800 bp) in the size of the payload correlate with a shift towards packaging 3 copies. As such, Eligobiotics® produced with p779 (12.428 kb) packaged preferentially 3 copies of the payload while approximately a third of the EBs contained 4 copies of the payload (
Thus, it appears that p1392 is close to an ideal size to package exclusively 4 copies of payload in phage-derived capsids, yielding an homogenous population. Increasing the size of the payload compared to p1392 generates more heterogeneous Eligobiotics® populations, with increasing proportions of EBs containing 3 copies of payload. From this dataset, it appears that there is a lower limit for concatemer packaging close to 36 kb, as described in the literature [28]. p1085, with a size of 12.125 kb, could package 3 copies per head (36.375 kb) or 4 copies per head (48.5 kb), although the 4 copies species is preferred as seen in
From these data, it can also be predicted which sizes would give packaging of single and multimeric species, as shown below in Tables 2 and 3. Smaller sizes yielding single packaged species are generally preferred for several reasons, including ease of manipulation and lower probability of introducing unwanted restriction sites. Finally, sizes that allow for very efficient packaged species that are not too small (26-39 kb) or too large (50-51 kb) are also preferred in some cases as it has been shown that the amount of DNA present in the capsid may alter the packaging and stability of the particles due to intracapsid pressure [29]-[30]. Finally, sizes that are large enough to allow for production of packaged phagemids at high titer are also more particularly preferred.
