Patent Application
20250154526
The present application relates to the fields of gene therapy and molecular biology. More specifically, the present invention relates to a method for producing a modified adeno-associated virus (AAV) capsid and to a modified AAV capsid produced by said method, as well as to an isolated nucleic acid encoding said modified capsid and a vector based on recombinant adeno-associated virus for delivering a heterologous nucleic acid sequence to a subject, which includes said modified capsid.
Adeno-associated virus (AAV) is a small (25 nm), independent replication-defective, nonenveloped virus. Many different AAV serotypes have been described in human and primates. The adeno-associated virus genome is composed of (+ or −) single-stranded DNA (ssDNA) being about 4,700 nucleotides long. At the ends of a genomic DNA molecule there are accommodated terminal inverted repeats (ITRs). The genome comprises two open reading frames (ORFs): Rep and Cap comprising several alternative reading frames encoding various protein products. The rep products are essential for AAV replication, whereas three capsid proteins (VP1, VP2, and VP3), along with other alternative products, are encoded by the Cap gene. VP1, VP2, and VP3 proteins are present at 1:1:10 ratio to form an icosahedral capsid (Xie Q. et al. The atomic structure of adeno-associated virus (AAV-2), a vector for human gene therapy. Proc Natl Acad Sci USA, 2002; 99:10405-10410). During recombinant AAV (rAAV) vector production, an expression cassette flanked by ITR is packaged into an AAV capsid. The genes required for AAV replication are not included in the cassette. Recombinant AAV is considered to be one of the safest and most widely used viral vectors for in vivo gene transfer. Vectors can infect cells of multiple tissue types to provide strong and sustained transgene expression. They are also non-pathogenic, and have a low immunogenicity profile (High K A et al., “rAAV human trial experience” Methods Mol Biol. 2011; 807:429-57).
One of the urgent purposes of research in the area of development of effective gene therapy is optimization of vectors to improve certain properties of the given vectors.
The various AAV serotypes are characterized by affinity for distinct host cell surface receptors, toward which they have tropism. Thus, the primary known receptor for AAV2 is heparan sulfate proteoglycan, the coreceptors are integrin heterodimer aVβ5, fibroblast growth factor receptor type 1, and hepatocyte growth factor receptor, c-Met. AAV12 binds to heparan sulfate proteoglycans and sialic acid. AAV4 and AAV5 bind to N- and O-linked sialic acids, respectively. AAV5 activates the platelet-derived growth factor receptor. Further, a relationship has been established between the amino acid sequence of AAV capsid proteins and the process of assembly thereof, encapsidation of the genome, affinity for different types of receptors represented on the surface of host cells (Govindasamy L. et. al. Structural insights into adeno-associated virus serotype 5. J Virol. 2013 October; 87 (20): 11187-99).
The international application WO2012145601 describes adeno-associated virus (AAV) virions with variant capsid protein, wherein the AAV virions exhibit greater infectivity of retinal cells, when administered via intravitreal injection, compared to wild-type AAV.
The international application WO2013158879 describes an adeno-associated virus (AAV) vector for delivering to a subject a heterologous nucleic acid sequence comprising the capsid protein VP1 comprising one or more lysine substitutions, wherein one lysine substitution is K137R, wherein said lysine substitution is effective for inhibiting ubiquitination of said capsid protein, thereby increasing transduction efficiency of said AVV vector in target cells.
To date, there is a need for AAV with improved properties compared to wild-type AAV, for example, which have increased transduction ability, greater specific ability to transduce cells of target organs and tissues, increased capsid capacity, increased efficiency of packaging of AAV viral genomes, as well as increased efficiency of generation due to highly efficient production (assembly) of encapsidated viral vectors based on recombinant adeno-associated virus (rAAV).

Viruses of the family Parvoviridae are small DNA-containing animal viruses. The Parvoviridae family may be divided into two subfamilies: the Parvovirinae, which members infect vertebrates, and the Densovirinae, which members infect insects. By 2006, there have been 11 serotypes of adeno-associated virus described (Mori, S. ET AL., 2004, “Two novel adeno-associated viruses from cynomolgus monkey: pseudotyping characterization of capsid protein”, Virology, T. 330 (2): 375-83). Serotype 12 of the adeno-associated virus was described in 2008 (Michael Schmidt ET AL., Adeno-associated virus type 12 (AAV12): a novel AAV serotype with sialic acid- and heparan sulfate proteoglycan-independent transduction activity, J Virol. 2008 February; 82 (3): 1399-406. doi: 10.1128/JVI.02012-07). All of the known serotypes can infect cells from multiple tissue types. Tissue specificity is determined by the capsid protein serotype; therefore, the adeno-associated virus-based vectors are constructed by assigning the desired serotype. Further information on parvoviruses and other members of the Parvoviridae has been described in the literature (Kenneth I. Berns, «Parvoviridae: The Viruses and Their Replication», Chapter 69 in Fields Virology (3d Ed. 1996)).
The genomic organization of all known AAV serotypes is very similar. The genome of AAV is a linear, single-stranded DNA molecule that is less than about 5000 nucleotides (nt) in length. Inverted terminal repeats (ITR) flank unique coding nucleotide sequences of proteins (Rep) that are essential for the virus life cycle, as well as sequences of overlapping capsid proteins (Cap). The Cap gene encodes VP proteins (VP1, VP2 and VP3), which form a capsid, as well as AAP (protein activating adeno-associated virus (AAV) assembly (Sonntag F, Köthe K, Schmidt K, et al. The assembly-activating protein promotes capsid assembly of different adeno-associated virus serotypes. J Virol. 2011; 85 (23): 12686-12697. doi: 10.1128/JVI.05359-11) and MAAP (membrane-associated accessory protein (Ogden P J, Kelsic E D, Sinai S, Church G M. Comprehensive AAV capsid fitness landscape reveals a viral gene and enables machine-guided design. Science. 2019; 366 (6469): 1139-1143. doi: 10.1126/science.aaw2900). The AAV genome flanking sequences which are 145 nucleotides long are self-complementary and are organized such that an energetically stable intramolecular duplex forming a T-shaped hairpin may be formed. Such hairpin structures function as an origin for virus DNA replication, serving as primers for the cellular DNA polymerase complex. Following wild-type AAV (wtAAV) infection in mammalian cells, the Rep genes (e.g. Rep78 and Rep52) are expressed using the P5 promoter and the P19 promoter, respectively, and the both Rep proteins have a certain function in the replication of the viral genome. A splicing event in the Rep open reading frame (Rep ORF) results in the expression of actually four Rep proteins (e.g. Rep78, Rep68, Rep52, and Rep40). However, it has been shown that the unspliced mRNA encoding Rep78 and Rep52 proteins is sufficient for AAV vector production in mammalian cells.

Transcription of these genes starts from a single promoter, p40. The molecular weights of the corresponding proteins are 87, 72, and 62 kDa, respectively. All of the three proteins are translated from a single mRNA. Following transcription, pre-mRNA can be spliced in two different manners, where either longer or shorter intron is excised to form mRNAs of 2300 or 2600 nucleotide long.
Thus, the introduction of mutations into the Cap gene will affect not only the AAV capsid protein VP1, but also the AAV VP2 and VP3 capsid proteins.

In one aspect, the present invention relates to a nucleic acid that encodes any of the above modified capsids.
In any embodiment of the invention, the nucleic acid molecule may be isolated.
The terms “nucleic acid”, “nucleic sequence”, “nucleic acid sequence”, “polynucleotide”, “oligonucleotide”, “polynucleotide sequence” and “nucleotide sequence”, used interchangeably in the present description, mean a precise sequence of nucleotides, modified or not, determining a fragment or a region of a nucleic acid, containing unnatural nucleotides or not, and being either a double-strand DNA or RNA, a single-strand DNA or RNA, or transcription products of said DNAs.
As used in the present description, polynucleotides include, as non-limiting examples, all nucleic acid sequences which are obtained by any means available in the art, including, as non-limiting examples, recombinant means, i.e. the cloning of nucleic acid sequences from a recombinant library or a cell genome, using ordinary cloning technology and PCR and the like, and by synthetic means.
It should also be included here that the present invention does not relate to nucleotide sequences in their natural chromosomal environment, i.e. in a natural state. The sequences of the present invention have been isolated and/or purified, i.e. they were sampled directly or indirectly, for example by copying. Thus, isolated nucleic acids obtained by recombinant genetics, by means, for example, of host cells, or obtained by chemical synthesis should also be mentioned here.
A reference to a nucleotide sequence encompasses the complement thereof unless otherwise specified. Thus, a reference to a nucleic acid having a particular sequence should be understood as one which encompasses the complementary strand thereof with the complementary sequence thereof.
An “isolated” nucleic acid molecule is one which is identified and separated from at least one nucleic acid molecule-impurity, which the former is bound to in the natural source of antibody nucleic acid. An isolated nucleic acid molecule is different from the form or set in which it is found under natural conditions. Thus, an isolated nucleic acid molecule is different from a nucleic acid molecule that exists in cells under natural conditions.
In some embodiments of the invention, the isolated nucleic acid is DNA.

“Any other nucleotide sequence encoding the corresponding amino acid sequence of the given modified protein” refers to a nucleic sequence that is alternative to said nucleic sequence, as, due to the degeneracy of genetic code, a wide range of various DNA sequences can encode the same amino acid sequence. It is well within the skill of a person trained in the art to create these alternative DNA sequences encoding the same amino acid sequences. Such variant DNA sequences are within the scope of the present invention.
In some embodiments, the isolated nucleic acid encoding any of the above modified capsids comprises any of the above nucleic acid sequences or combinations thereof.
In one aspect, the present invention relates to a vector based on recombinant adeno-associated virus for delivering to a subject a heterologous nucleic acid sequence, which includes:
The terms “vector based on recombinant adeno-associated virus”, “recombinant virus based on AAV”, “virus-like particle based on AAV”, “recombinant viral AAV strain”, “recombinant AAV vector” or “rAAV vector” as used in the present description have the same meaning.
In some embodiments of the invention, the rAAV vector includes a heterologous nucleic acid sequence comprising regulatory sequences that provide product expression, wherein the product of expression of the heterologous nucleic acid sequence is a therapeutic polypeptide or reporter polypeptide.
The rAAV vector according to the invention does not comprise nucleotide sequences of genes encoding sequences of proteins (Rep) that are essential for the virus life cycle, as well as sequences of overlapping capsid proteins (Cap).
The capsid is characterized in detail in the above section of the description.
“Regulatory sequences that provide the expression of product encoded by the heterologous nucleic acid sequence in target cells”, as used in the present invention, mean polynucleotide sequences that are necessary to influence the expression and processing of coding sequences to which they are cloned. Expression control sequences include appropriate transcription initiation, termination, promoter and enhancer sequences; efficient RNA processing signals such as splicing and polyadenylation signals; sequences that stabilize cytoplasmic mRNA; sequences that enhance translation efficiency (i.e. Kozak consensus sequence); sequences that enhance protein stability; and when desired, sequences that enhance protein secretion. The nature of such control sequences differs depending upon the host organism; in prokaryotes, such control sequences generally include the promoter of ribosome binding site, and transcription termination sequences; in eukaryotes, typically, such control sequences include promoters and transcription termination sequences. The term “regulatory sequences” includes at least all components, the presence of which is essential for expression and processing, and can also include additional components, the presence of which is advantageous, for example, leader peptide sequences.
As used in the present description, the term “promoter” refers to a nucleic acid fragment that controls the transcription of one or more coding sequences and is structurally identified by the presence of a binding site for DNA-dependent RNA polymerase, transcription initiation sites and any other DNA sequences, including, but not limited to transcription factor binding sites, repressor and activator protein binding sites, and any other sequences of nucleotides known to one of skill in the art that directly or indirectly regulate the level of transcription with said promoter. A “constitutive” promoter is a promoter that is active in most tissues under typical physiological and developmental conditions. An “inducible” promoter is a promoter that is physiologically or developmentally regulated, e.g. under the influence of a chemical inducer. A “tissue specific” promoter is only active in specific types of tissues or cells.
Promoters that are used for high-level production of polypeptides in eukaryotic cells and, in particular, in mammalian cells, should be strong and preferably active in a wide range of cell types. Strong constitutive promoters which are capable of driving expression in many cell types are well known in the art and, therefore, it is not herein necessary to describe them in detail. In accordance with the idea of the present invention, it is preferable to use the cytomegalovirus (CMV) promoter. A promoter or promoter/enhancer derived from the immediate early (IE) region of human cytomegalovirus (hCMV) is particularly suitable as a promoter for the rAAV5 vector of the present invention. Human cytomegalovirus (hCMV) immediate early (IE) region and functional expression-inducing and/or functional expression-enhancing fragments derived therefrom, for example, have been disclosed in EP0173177 and EP0323997, and are well known in the art. Thus, several fragments of the hCMV immediate early (IE) region may be used as a promoter and/or promoter/enhancer.
The terms “enhancers” or “enhancer” as used herein may refer to a DNA sequence that is located adjacent to the DNA sequence that encodes a recombinant product. Enhancer elements are typically located in a 5′ direction from a promoter element or can be located downstream of or within a coding DNA sequence (e.g. a DNA sequence transcribed or translated into a recombinant product or products). Hence, an enhancer element may be located 100 base pairs, 200 base pairs, or 300 or more base pairs upstream of a DNA sequence that encodes a recombinant product, or downstream of said sequence. Enhancer elements may increase the amount of a recombinant product being expressed from a DNA sequence above the level of expression associated with a single promoter element. Multiple enhancer elements are readily available to those of ordinary skill in the art.
In some embodiments of the invention, the heterologous nucleic acid sequence comprising regulatory sequences providing the expression of a product encoded by the heterologous nucleic acid sequence in target cells may include the following elements in the 5′-end to 3′-end direction:
In some embodiments, the nucleic acid encoding the product (transgene) is at least one gene encoding a protein. In some embodiments, the transgene encodes at least one small inhibitory nucleic acid. In some embodiments, the transgene encodes at least one reporter molecule. In some embodiments, the small inhibitory nucleic acid is miRNA. In some embodiments, the small inhibitory nucleic acid is sponge miRNA or TuD-RNA, which inhibits the activity of at least one miRNA in an animal. In some embodiments, miRNA is expressed in a cell of the target tissue. In some embodiments, the target tissue is the tissue of the liver, central nervous system (CNS), eyes, gastrointestinal tract, respiratory tract, breast, pancreas, urinary tract or uterine tissue.
In some embodiments, the rAAV vector has a product of expression of the heterologous nucleic acid sequence, which is a therapeutic polypeptide or a reporter polypeptide.
In some embodiments, the rAAV vector comprises a heterologous nucleic acid sequence encoding a product that is a therapeutic polypeptide, wherein the therapeutic polypeptide is a coagulation factor selected from the group consisting of Factor VIII, Factor IX, or a functional variant thereof.
In some embodiments, the rAAV vector comprises a heterologous nucleic acid sequence encoding a product that is Factor VIII or a functional variant thereof.
In some embodiments, the rAAV vector comprises a heterologous nucleic acid sequence encoding a product that is Factor IX or a functional variant thereof.
In some embodiments, the rAAV vector comprises a heterologous nucleic acid sequence encoding a product that is the SMN1 protein (survival motor neuron protein)
In some embodiments, the rAAV vector comprises a heterologous nucleic acid sequence encoding a product that is the RBD-S polypeptide (recombinant receptor-binding domain of S glycoprotein) of SARS-cov2 (severe acute respiratory syndrome coronavirus 2).
The following examples are provided for better understanding of the invention. These examples are for purposes of illustration only and are not to be construed as limiting the scope of the invention in any manner.
All publications, patents, and patent applications cited in this specification are incorporated herein by reference. Although the foregoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it will be readily apparent to those of ordinary skill in the art in light of the teachings of this invention that certain changes and modifications may be made thereto without departing from the spirit or scope of the appended embodiments.
Standard methods were used to manipulate DNA as described in Sambrook, J. et al, Molecular cloning: A laboratory manual; Cold Spring Harbor Laboratory Press, Cold Spring Harbor, New York, 2012. The molecular biological reagents were used according to the manufacturer protocols.
Desired gene segments were prepared from oligonucleotides made by chemical synthesis. The gene segments of 300-4,000 bp long, which were flanked by singular restriction sites, were assembled by annealing and ligation of oligonucleotides including PCR amplification and subsequently cloned via the specified restriction sites. The DNA sequences of the subcloned gene fragments were confirmed by DNA sequencing.
DNA Sequence Determination DNA sequences were determined by Sanger sequencing.
The Infomax's Vector NTI Advance suite version 8.0 and SnapGene version 5.1.4.1 were used for sequence creation, mapping, analysis, annotation and illustration.
The results indicate an average value±standard deviation (SD), analysis of variance (ANOVA) was employed to compare the test and control results, and they were determined to be statistically significant.
The design of AAV5 capsid mutations is based on a high degree of structural similarity of capsid proteins within the family Parvoviridae, including non-AAV viruses. The selection of a substitution consists of three steps of:
The structures of the three-dimensional models of AAV5 and the template capsid are pre-prepared; the pre-preparation consists in completing the missing atoms in the structure using the Prepwizard utility from Schrodinger Suite.
In step 1, the interaction interface refers to a set of capsomere protein polypeptide chain fragments interacting with the amino acids of an adjacent pentameric subunit, wherein the pentameric subunit refers to a capsid structural element having the shape of a regular pentagon and consisting of 5 capsomere proteins located around the central pore (L. M. Drouin and M. Agbandje-McKenna. Adeno-associated virus structural biology as a tool in vector development. Future Virol., vol. 8, no. 12, pp. 1183-1199, 2013.).
The second step comprises aligning structurally the AAV5 capsid and the template capsid using the Structure Alignment utility from Schrodinger Suite. Following the results of alignment, for each AAV5 amino acid from the interaction interface of adjacent pentameric subunits, the closest thereto amino acid of the template capsid (structural analogue of the initial amino acid) is determined, which is considered a potential substitution. There is no structural analogue of the initial amino acid if in the vicinity of the nearest thereto amino acid of the template capsid there is present another AAV5 amino acid, the distance to which is less than that to the initial amino acid. Here, the distance between amino acids is estimated by that between alpha-carbon atoms.
After structural analogues have been determined for all amino acids of the interaction interface of adjacent pentameric subunits, the decision to substitute is made in accordance with Examples 2, 3 and 4.
After aligning structurally the AAV5 capsid to the template capsid, we get a pairwise structural correspondence between amino acid residues thereof. In one of the cases, the decision to substitute the initial amino acid for the corresponding amino acid of the template capsid is made following the results of comparing the van der Waals volumes of the amino acid side substituents (N. J. Darby, S. S. N. J. Darby, and T. E. Creighton, Protein Structure. IRL Press at Oxford University Press, 1993; Table 1). A mutation is introduced if the following conditions are met:
The exclusion of cysteine and methionine from the amino acids for potential substitution is due to their significant reactivity, in particular oxidizability.
Table 2 shows the results of applying the subject method for designing mutations in the AAV5 capsid using three template capsids: HBOV1 (PDBid 5urf), B19 (PDBid 1s58), BPV (PDBid 4qc8). The first column contains amino acids from the interaction interface of adjacent pentameric subunits of the AAV5 capsid, the remaining columns contain amino acids produced after pairwise structural alignment of AAV5 to each one of the capsids: HBOV1, B19 and BPV. An asterisk indicates amino acids suitable for substitution in accordance with the size criterion for the side substituent and the prohibited substitution for cysteine and methionine.
Interaction interface for a given subunit is intended to refer to all amino acids, at least one atom of which is present at distance lower than 5 Å from any atom of adjacent pentameric subunits.
For AAV5, the calculation was made based on the capsid structure PDB ID: 6JCT.
According to the calculation, its interaction interface between adjacent pentameric AAV5 subunits includes the following ranges of AAV5 capsid protein VP1 residues: 220-226, 283-293, 339-342, 385-392, 412-435, 462-466, 590-598, 611-626, 677-685, 721-724.
In accordance with Example 1, after aligning structurally the AAV5 capsid and the template capsid, we get a pairwise structural correspondence between amino acid residues thereof. In one of the cases, the decision to substitute the initial amino acid for the corresponding amino acid of the template capsid is made based on the analysis of the microenvironment for both the initial amino acid and a structural analogue thereof. In particular, a positive decision to substitute is made if in a pair of corresponding amino acids in the template capsid there is disposed an amino acid with a polar side substituent, and in AAV5 there is disposed one with a non-polar substituent, wherein the both amino acids have at least one polar contact to an adjacent pentameric subunit of the capsid. An amino acid is assumed to have a polar contact if at a distance of no more than 5 Å from any atom of the side substituent other than hydrogen there is disposed at least one atom of the polar group of the side substituent of another amino acid of another capsomere (Table 3). By analogy with Example 2, substitutions for cysteine and methionine are also not allowed.
Table 4 shows the results of applying the subject method for designing mutations in the AAV5 capsid using three template capsids: HBOV1 (PDBid 5urf), B19 (PDBid 1s58), BPV (4qc8). The first column contains amino acids from the interaction interface of adjacent pentameric subunits of the AAV5 capsid, for which suitable substitutions were found in one of the three capsids: HBOV1, B19 and BPV. The remaining columns contain amino acids produced after pairwise structural alignment of AAV5 to each of the capsids. An asterisk indicates amino acids suitable for substitution in accordance with the increased number criterion for the polar contacts and the prohibited substitution for cysteine and methionine.
In accordance with Example 1, after aligning structurally the AAV5 capsid and the template capsid, we get a pairwise structural correspondence between amino acid residues thereof. In one of the cases, the decision to substitute the initial amino acid for the corresponding amino acid of the template capsid is made based on the analysis of the microenvironment for both the initial amino acid and a structural analogue thereof. In particular, a positive decision to substitute is made if in a pair of corresponding amino acids in the AAV5 capsid there is present a polar amino acid residue that forms at least a single polar contact with an adjacent pentameric subunit, whereas in the template capsid there is disposed a non-polar amino acid residue. Further, by analogy with Example 2, cysteine or methionine residues are not considered for substitution.
Table 5 shows the results of applying the subject method for designing mutations in the AAV5 capsid using three template capsids: HBOV1 (PDBid 5urf), B19 (PDBid 1s58), BPV (4qc8).

M. Drouin and M. Agbandje-McKenna. Adeno-associated virus structural biology as a tool in vector development. Future Virol., vol. 8, no. 12, pp. 1183-1199, 2013.).
The second step comprises aligning structurally the AAV9 capsid to the template capsid using the Structure Alignment utility from Schrodinger Suite. Following the results of alignment, for each AAV9 amino acid from the interaction interface of adjacent pentameric subunits, the closest thereto amino acid of the template capsid (structural analogue of the initial amino acid) is determined, which is considered a potential substitution. There is no structural analogue of the initial amino acid if in the vicinity of the nearest thereto amino acid of the template capsid there is present another AAV9 amino acid, the distance to which is less than that to the initial amino acid. Here, the distance between amino acids is estimated by that between alpha-carbon atoms.
After structural analogues have been determined for all amino acids of the interaction interface of adjacent pentameric subunits, the decision to substitute is made in accordance with Examples 6, 7 and 8.
After aligning structurally the AAV9 capsid to the template capsid, we get a pairwise structural correspondence between amino acid residues thereof.

An asterisk indicates amino acids suitable for substitution in accordance with the size criterion for the side substituent and the prohibited substitution for cysteine and methionine.
Interaction interface for a given subunit is intended to refer to all amino acids, at least one atom of which is present at distance lower than 5 Å from any atom of adjacent pentameric subunits. For AAV9, the calculation was made based on the structure PDB ID: 3UX1.
According to the calculation, its interaction interface between adjacent pentameric subunits of AAV9 includes the following ranges of AAV9 capsid protein VP1 residues: 230-236, 294-304, 350-353, 394-401, 421-444, 476-480, 601-609, 622-637, 689-697, 733-736.
In accordance with Example 5, following the results of aligning structurally the AAV9 capsid to the template capsid, we get a pairwise structural correspondence between amino acid residues thereof. In one of the cases, the decision to substitute the initial amino acid for the corresponding amino acid of the template capsid is made based on the analysis of the microenvironment for both the initial amino acid and a structural analogue thereof. In particular, a positive decision to substitute is made if in a pair of corresponding amino acids in the template capsid there is disposed an amino acid with a polar side substituent, and in AAV9 there is disposed one with a non-polar substituent, wherein the both amino acids have at least one polar contact with an adjacent pentameric subunit of the capsid. An amino acid is assumed to have a polar contact if at a distance of no more than 5 Å from any atom of the side substituent other than hydrogen there is disposed at least one atom of the polar group of the side substituent of another amino acid of another capsomere (Table 3). By analogy with Example 6, substitutions for cysteine and methionine are also not allowed.

Table 8 shows the results of applying the subject method for designing mutations in the AAV9 capsid using three template capsids: HBOV1 (PDBid 5urf), B19 (PDBid 1s58), BPV (4qc8). The first column contains amino acids from the interaction interface of adjacent pentameric subunits of the AAV9 capsid, for which suitable substitutions were found in one of the three capsids: HBoV1, B19 and BPV. The remaining columns contain amino acids produced following the results of pairwise structural alignment of AAV9 to each of the template capsids. An asterisk indicates amino acids suitable for substitution in accordance with the increased number criterion for the polar contacts and the prohibited substitution for cysteine and methionine.
Libraries of AAV5 capsid variants were produced by random mutagenesis of the Cap gene sequence (Davidsson M. et al., 2016). Briefly, the wild-type sequence of the Cap gene serotype 5 (GenBank ID AF085716.1) was assembled de novo, the synthesized wild-type AAV5 capsid gene was thereafter fragmented using uracil-DNA glycosylase, the resulting fragments were assembled to a full-length Cap gene using DNA polymerase not having a proofreading activity (resulting in random mutations in the sequence). The full-length mutant variants were cloned into the carrier plasmid pAAV-linker (
Viral particles having increased transducing activity were positively selected in vitro on CHO-K1-S cells. Further, for transduction, we used particles that were purified using ultracentrifugation in a iodixanol gradient. After 48 hours, the cells were harvested and genomic DNA was isolated for subsequent amplification of the viral genome sequences capable of efficient transduction. The resulting sequences were thereafter re-cloned and re-produced for subsequent selection iterations to enrich the library with variants having the highest transduction efficiency. Following 5 rounds of selection, the capsid genes of 30 clones were sequenced to determine the most successful mutations and combinations thereof. The sequencing results showed that the predominant combinations of mutations were S2A, T711S in AAV5 VP1 and capsid variants containing S2A, T711S, S651A in AAV5 VP1, which were about 20% of the clones. Capsid variants comprising the mutation S651A in AAV5 VP1 were also selected. These capsid variants were cloned into vectors for producing viral particles and further used for visualizing and comparing the transduction profiles relative to wild-type AAV5.
To produce and subsequently select recombinant viral particles from the resulting sequence library, a series of plasmids was developed as follows: a carrier plasmid, a plasmid comprising the Rep gene sequence, as well as a construct comprising adenoviral genes that are required for the replication of viral particles.
The carrier plasmid pAAV-linker (
The plasmid pAAV-Rep comprising the Rep gene sequence (
The adenoviral genes for producing the recombinant viral particles were sourced from the construct pHelper (
Gene sequences of wild-type AAV serotype 5 capsid (GenBank ID AF085716.1) and those of wild-type AAV serotype 9 capsid (GenBank ID AY530579.1) were synthesized de novo with the inclusion of SwaI site from the 5′ end and NotI site from the 3′ end into each one of the synthesized sequences, respectively; following treatment with SwaI/NotI restriction endonucleases (New England Biolabs, USA), each of the sequences was cloned into the plasmid vector pAAV-Rep (
Mutations were introduced into the sequence of wild-type AAV capsid using a commercial QuikChange II Site-directed mutagenesis kit (Agilent, USA) according to the manufacturer's instructions. PCR primers were developed using the QuikChange Primer Design software (Agilent, USA) (Table 9, Table 10). Briefly, the procedure based on site-directed mutagenesis was performed using the plasmids pAAV-RC5 or pAAV-RC9 as a template, respectively. To introduce mutations, the first step included a PCR reaction in individual test tubes for each mutant and control sample supplemented with corresponding oligonucleotides. The second step included treatment with restrictase according to the manufacturer's protocol to remove the template plasmid DNA, the competent E. coli XL-1Blue cells were transformed with the resulting mixture. The resulting clones were analyzed using PCR for specific regions in the target plasmid, the selected mutants were subject to sequencing before use.

The CHO-K1-S cells were plated into the wells of 12-well plates. Seeding was made into the following growth medium: DMEM/F12 supplemented with glutamine, glucose content was 4.5 g/1, 5% bovine serum. Cell seeding density was 10,000 cell/cm2. During the transduction run, pre-prepared cells were transduced at MOI of 200,000 vg/cell. All samples were run in triplicates. Intact cells were used as a negative control.
The amount of FIX protein in the culture liquid 7 days post transduction was assessed using the Human Factor IX ELISA Kit. We used a 1:25 dilution of the samples. The procedure was carried out according to the manufacturer's instructions.
