Abstract
A promising approach to the development of new means for preventing infection caused by tick-borne encephalitis virus can be DNA vaccines encoding polyepitope T-cell immunogens. A DNA vaccine pVAX-AG4-ub encoding an artificial polyepitope immunogen that includes cytotoxic and T-helper epitopes from the NS1, NS3, NS5, and E proteins of the tick-borne encephalitis virus has been obtained. The developed construct ensured the synthesis of the corresponding mRNAs in transfected eukaryotic cells. Immunization of mice with pVAX-AG4-ub induced the formation of a virus-specific T-cell response providing 50% protection from lethal infection with the virus.

Abstract
An artificial T-cell immunogen consisting of conserved fragments of different proteins of the SARS-CoV-2 virus and its immunogenic properties were studied in BALB/c mice. To create a T-cell immunogen, we used an approach based on the design of artificial antigens that combine many epitopes from the main proteins of the SARS-CoV-2 virus in the one molecule. The gene of the engineered immunogen protein was cloned as part of the pVAX1 plasmid in two versions: with an N-terminal ubiquitin and without it. The obtained plasmids were analyzed for their ability to provide the synthesis of the immunogen protein in vitro and in vivo. It has been shown that protein product of the created artificial genes is actively processed in HEK293T cells and induces cellular immunity in mice.

Abstract
We performed a search for nanoantibodies that specifically interact with the receptor-binding domain (RBD) of the SARS-CoV-2 surface protein. The specificity of single-domain antibodies from the blood sera of a llama immunized with RBD of SARS-CoV-2 surface protein S (variant B.1.1.7 (Alpha)) was analyzed by ELISA. Recombinant trimers of the SARS-CoV-2 spike protein were used as antigens. In this work, a set of single-domain antibodies was obtained that specifically bind to the RBD of the SARS-CoV-2 virus.

Abstract
Vaccination is the most efficient way to prevent infectious diseases. mRNA-based vaccines is a new approach to vaccine development, which have several very useful advantages over other types of vaccines. Since mRNA encodes only the target antigen there is no potential risk of infection as in the case with attenuated or inactivated pathogens. The mode of action of mRNA-vaccines implies that their genetic information is expressed only in the cytosol, leaving very little possibility of mRNA integration into the host's genome. mRNA-vaccines can induce specific cellular and humoral immune responses, but do not induce the antivector immune response. The mRNA-vaccine platform allows for easy target gene replacement without the need to change the production technology, which is important to address the time lag between the epidemic onset and vaccine release. The present review discusses the history of mRNA vaccines, mRNA vaccine production technology, ways to increase mRNA stability, modifications of the cap, poly(A)-tail, coding and noncoding parts of mRNA, target mRNA vaccine purification from byproducts, and delivery methods.

Abstract
During the COVID-19 pandemic, the development of prophylactic vaccines, including those based on new platforms, became highly relevant. One such platform is the creation of vaccines combining DNA and protein components in one construct. For the creation of DNA vaccine, we chose the full-length spike protein (S) of the SARS-CoV-2 virus and used the recombinant receptor-binding domain (RBD) of the S protein produced in CHO-K1 cells as a protein component. The immunogenicity of the developed combined vaccine and its individual components was compared and the contribution of each component to the induction of the immune response was analyzed. The combined DNA/protein vaccine possesses the advantages of both underlying approaches and is capable of inducing both humoral (similar to subunit vaccines) and cellular (similar to DNA vaccines) immunity.

Abstract
A viral threat can arise suddenly and quickly turn into a major epidemic or pandemic. In such a case, it is necessary to develop effective means of therapy and prevention in a short time. Vaccine development takes decades, and the use of antiviral compounds is often ineffective and unsafe. A quick response may be the use of convalescent plasma, but a number of difficulties associated with it forced researchers to switch to the development of safer and more effective drugs based on monoclonal antibodies (mAbs). In order to provide protection, such drugs must have a key characteristic-neutralizing properties, i.e., the ability to block viral infection. Currently, there are several approaches to produce mAbs in the researchers' toolkit, however, none of them may serve as a gold standard. Each approach has its own advantages and disadvantages. The choice of the method depends both on the characteristics of the virus and on time constraints and technical challenges. This review provides a comparative analysis of modern methods to produce neutralizing mAbs and describes current trends in the design of antibodies for therapy and prevention of viral diseases.

Abstract
The development of preventive vaccines became the first order task in the COVID-19 pandemic caused by SARS-CoV-2. This paper reports the construction of the pVAX-RBD plasmid containing the Receptor-Binding Domain (RBD) of the S protein and a unique signal sequence 176 which promotes target protein secretion into the extracellular space thereby increasing the efficiency of humoral immune response activation. A polyglucine-spermidine conjugate (PGS) was used to deliver pVAX-RBD into the cells. The comparative immunogenicity study of the naked pVAX-RBD and pVAX-RBD enclosed in the PGS envelope showed that the latter was more efficient in inducing an immune response in the immunized mice. In particular, RBD-specific antibody titers were shown in ELISA to be no higher than 1 : 1000 in the animals from the pVAX-RBD group and 1 : 42 000, in the pVAX-RBD-PGS group. The pVAX-RBD‒PGS construct effectively induced cellular immune response. Using ELISpot, it has been demonstrated that splenocytes obtained from the immunized animals effectively produced INF-γ in response to stimulation with the S protein-derived peptide pool. The results suggest that the polyglucine-spermidine conjugate-enveloped pVAX-RBD construct may be considered as a promising DNA vaccine against COVID-19.

Abstract
For the first time, the chymosin gene (CYM) of a maral was characterized. Its exon/intron organization was established using comparative analysis of the nucleotide sequence. The CYM mRNA sequence encoding a maral preprochymosin was reconstructed. Nucleotide sequence of the CYM maral mRNA allowed developing an expression vector to ensure production of a recombinant enzyme. Recombinant maral prochymosin was obtained in the expression system of Escherichia coli [strain BL21 (DE3)]. Total milk-coagulation activity (MCA) of the recombinant maral chymosin was 2330 AU/ml. The recombinant maral prochymosin relative activity was 52955 AU/mg. The recombinant maral chymosin showed 100-81% MCA in the temperature range 30-50°C, thermal stability (TS) threshold was 50°C, and the enzyme was completely inactivated at 70°C. Preparations of the recombinant chymosin of a single-humped camel and recombinant bovine chymosin were used as reference samples. Michaelis-Menten constant (Km), turnover number (kcat), and catalytic efficiency (kcat/Km) of the recombinant maral chymosin, were 1.18 ± 0.1 µM, 2.68 ± 0.08 s-1 and 2.27± 0.10 µm M-1·s-1, respectively.

Abstract
After the genome sequence of SARS-CoV-2 (Severe acute respiratory syndrome-related coronavirus 2) was published and the number of infected people began to increase rapidly, many global companies began to develop a vaccine. Almost all known approaches to vaccine design were applied for this purpose, including inactivated viruses, mRNA and DNA-vaccines, vaccines based on various viral vectors, synthetically generated peptides and recombinant proteins produced in cells of insects and mammals. This review considers one of the promising vaccine platforms based on messenger RNA. Until recent years, mRNA-vaccination was out of practical implementation due to high sensitivity to nuclease degradation and consequent instability of drugs based on mRNA. Latest technological advances significantly mitigated the problems of low immunogenicity, instability, and difficulties in RNA-vaccine delivery. It is worth noting that mRNA-vaccines can efficiently activate both components of the immune system, i. e. T-cell and humoral responses. The essential advantage of mRNAvaccines includes fast, inexpensive, scalable and uniform production providing a large output of desirable products in vitro. Synthesis and purification processes significantly simplify the process technology of mRNA drugs with injectable purity. Thus, mRNA production via in vitro transcription is more advantageous as compared with DNA-vaccines since it is a chemical process without the use of cells. mRNA techniques make it possible to pass all the phases of vaccine development much faster in comparison with the production of vaccines based on inactivated viruses or recombinant proteins. This property is critically important when designing vaccines against viral pathogens as the main problem of disease control includes a time gap between an epidemic and vaccine development. This paper discusses studies on the development of vaccines against coronaviruses including SARS-CoV-2 with special attention to the mRNA technique.

Abstract
The human immunodeficiency virus (HIV-1) poses a serious risk to global public health. The development of a safe and effective vaccine could stop the HIV/AIDS pandemic. Much of the research focused on HIV-1 prevention through vaccination is aimed at developing immunogens and immunization strategies to induce the formation of antibodies with neutralizing activity against a broad range of HIV-1 isolates (bNAbs). The objective of this study was to develop immunogens capable of targeting an immune response to MPER, one of the regions of bNAb binding in Env. Two immunogens carrying MPER fragments on their scaffolds (protein YkuJ Bacillus subtilis and artificial polypeptide TBI) were constructed. Circular dichroism spectroscopy was used to show that the secondary structure of the immunogens was consistent with their theoretical models. The antigenic structure of the MPER-TBI and YkuJ-MPER proteins was characterized using bNAbs that recognize HIV-1 MPER (2F5, 4E10, and 10E8). The rabbit model made it possible to show the immunogenicity of the constructed recombinant proteins. The resulting serum was found to be cross-reactive with immunogens carrying MPER. The constructs designed and characterized in this study can be used for targeting the humoral immune response to MPER, which is known to be one of the sites of HIV-1 vulnerability.

Abstract
Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. When studying samples containing viruses, one confronts an unavoidable question of the quantitative determination of viral particles in the sample. One of the simplest and efficient approaches to quantitative determination of viral particles in preparation includes the use of electron microscopy; however, a high detection threshold is a significant limitation of this method (107 particles per ml). Usually, such sensitivity is insufficient and can result in error diagnosis. This study aims to develop a method making it possible to detect the number of viral particles more precisely and work with samples in which the concentration of particles is lower than 107/ml. The method includes a concentration of viral particles on the polyethersulfone membrane applied in centrifugal concentrators and subsequent calculation using an electron microscope. We selected env-pseudoviruses using a lentiviral system making it possible to obtain standardized samples of virus-like particles that are safer than a live virus. Suspension of viral particles (a volume of 20 ml) was placed into the centrifugal concentrator and centrifuged. After that, we took a membrane out of the centrifugal concentrator and evaluated the number of particles on the ultrathin section using an electron microscope. The number of viral particles on the whole surface of the filter (a square of 4 сm2) was 4×107 virions, the initial concentration of pseudoviruses in the sample was 2×106 per 1 ml (4×107 particles per 20 ml). As a result, the developed method enables one to evade the major disadvantage of quantitative determination of viruses using electron microscopy regarding a high detection threshold (concentration of particles 107/ml). Furthermore, the centrifugal concentrator makes it possible to sequentially drift a considerable volume of the suspension through the filter resulting in enhancement of test sensitivity. The developed approach results in increased sensitivity, accuracy, and reproducibility of quantitative analysis of various samples containing animal, plant or human viruses using electron microscopy.

Abstract
Polyepitope DNA vaccine inducing T-cell-mediated immune response against cancer-specific antigens is a promising tool for selective elimination of tumor cells. Breast cancer-specific polyepitope DNA vaccine was designed using TEpredict and PolyCTLDesigner software on the basis of immunogenic peptides of HER2 and Mammaglobin-1 (Mam) tumor antigens. LPS-free preparations of plasmid DNA encoding polyepitope T-cell antigen and full-length copies of HER2 and Mam antigens were obtained. TaqMan-PCR systems for evaluation of the expression of immunogens in cells were created. The protocol of vaccine DNA delivery into dendritic cells was optimized. Expression of the target immunogens in dendritic cells derived from human peripheral blood mononuclear fraction after transfection with plasmid DNA preparations is demonstrated.

Abstract
The human immunodeficiency virus-1 (HIV-1) has the ability to evade the adaptive immune response due to high mutation rates. Soon after the discovery of HIV-1, it was originally proposed that neutralizing of antibodies to the virus occurs rarely or cannot be elicited at all. In the 1990s, there appeared reports that sera of select HIV-1-infected individuals contained antibodies capable of neutralizing different virus subtypes. Such antibodies were named broadly neutralizing antibodies (bNAbs). Since 2009, the development of new cell technologies has intensified research efforts directed at identifying new bNAbs with a neutralization potency of over 90% of primary HIV-1 isolates. These antibodies have unique characteristics which include high levels of somatic mutations and unusually long variable loops that penetrate through the glycan shield of HIV-1 Env to contact the protein surface. In this review, we will attempt to summarize the latest data on bNAbs against HIV-1 in terms of their interactions with the sites of vulnerability on HIV-1 glycoproteins.

Abstract
Advances in defining HIV-1 CD8+ T cell epitopes and understanding endogenous MHC class I antigen processing enable the rational design of polyepitope vaccines for eliciting broadly targeted CD8+ T cell responses to HIV-1. Here we describe the construction and comparison of experimental DNA vaccines consisting of ten selected HLA-A2 epitopes from the major HIV-1 antigens Env, Gag, Pol, Nef, and Vpr. The immunogenicity of designed gene constructs was assessed after double DNA prime, single vaccinia virus boost immunization of HLA-A2 transgenic mice. We compared a number of parameters including different strategies for fusing ubiquitin to the polyepitope and including spacer sequences between epitopes to optimize proteasome liberation and TAP transport. It was demonstrated that the vaccine construct that induced in vitro the largest number of [peptide-MHC class I] complexes was also the most immunogenic in the animal experiments. This most immunogenic vaccine construct contained the N-terminal ubiquitin for targeting the polyepitope to the proteasome and included both proteasome liberation and TAP transport optimized spacer sequences that flanked the epitopes within the polyepitope construct. The immunogenicity of determinants was strictly related to their affinities for HLA-A2. Our finding supports the concept of rational vaccine design based on detailed knowledge of antigen processing.

Abstract
Hepatitis B core antigen is one of the most promising protein carriers of foreign epitopes of various human and animal pathogens. Chimeric HBcAg particles can be used as effective artificial immunogenes. Unfortunately, not all chimeric proteins are able to be particulated. The dependence of correct or incorrect folding of chimeric proteins on physical and chemical properties of inserts was studied with the help of ProAnalyst, SALIX and QSARPro computer programs. We have found that insertion of amino acids with high hydrophobicity, large volume, and high beta-strand index prevent self-assembling chimeric proteins. These factors are most important for the C-termini of inserts. Recommendations for obtaining correct folding of chimeric HBcAg particles have been given.

Abstract
For detection of spring viremia of carp virus (SVCV) DNA probes have been constructed using the reverse transcription-polymerase chain reaction (RT-PCR) amplification technique and cDNA cloning in plasmid and phage vectors. The specific primers for amplification of SVCV M and G genes were chosen and synthesized. Studies were carried out to establish the sensitivity and specificity of viral RNA detection in infected cell culture and pathogenic material from fish by the use of non-radioactive probes and RT-PCR. The efficiency of amplification with primers, complementary to the genome of the reference Fijan strain, was estimated in RT-PCR experiments with two SVCV strains. Under the same conditions, the quantity of PCR products amplified from the M2 strain was less than that from the ZL4 strain, which implies that the latter is more similar to the reference European SVCV Fijan isolate. Using DNA probes and dot-blot hybridization, SVCV was tested in samples taken from different organs of artificially infected carp with clinical signs of acute disease. The virus could be detected most reliably in fish brain. In most cases the hybridization signal was positive with samples having a viral titer of not less than 10(5) TCID50/g.

Abstract
The position of the amino terminus of the hepatitis B virus core antigen (HBcAg) within the core particle was studied. For this purpose, three recombinant analogs of HBcAg were designed. One analog, HBcAgR, was identical in amino acid sequences to the core polypeptide of the hepatitis B virus; the second, HBeAgR, differed from the authentic protein in deletion of 39 carboxy-terminal amino acids. The amino acid sequences of the third polypeptide, HBe delta N and of HBeAgR were similar, HBe delta N differed from HBeAgR only in replacement of 3 N-terminal amino acids by 16 amino acids of beta-galactosidase. The HBcAg analogs were compared with respect to their reaction with monoclonal antibody (mAb E1A7) to the amino-terminal linear epitope of hepatitis B virus e antigen. Although able to assemble into virus-like particles, the three analogs of HBcAg, reacted differently with mAb E1A7. It was demonstrated that mAb E1A7 reacted with both native and denatured HBeAgR. HBe delta N was not recognized by mAb E1A7. In contrast, HBcAgR reacted with mAb E1A7 only when denatured. Native HBcAgR did not react with mAb E1A7 when assembled into particles. Thus evidence was obtained that the amino terminus of HBcAg is not exposed on the particle surface.

Abstract
Three new approaches to design effective immunogens are considered. At first, we derived an expression vector from bacteriophage M13 allowing the exposure of short peptides on the virion surface. EIA demonstrates that antibodies against a recombinant phage carrying the antigenic determinant of the HIV-1 gag protein reacted with the 17-kDa core protein of the virus and also with its polyprotein precursor p55 in immunoblotting. In another approach, we chose the hepatitis B core antigen (HBcAg) particle as a vehicle for the presentation of foreign antigenic determinants to the immune system. Chimerical particles of HBcAg containing epitope of the VEE virus were obtained. A vector system for insertion of foreign antigenic determinants and production of both hybrid and wild HBcAg proteins were also obtained. The third approach relies on construction of immunogens from different T- and B-cell epitopes of the HIV-1. We suggested to construct HIV-1 vaccines in a form of the TBI (T- and B-cell epitopes containing Immunogen) with a predetermined tertiary structure, namely, a four-alpha-helix bundle. The gene of the TBI protein consisting of nine HIV-1 epitopes was synthesized and expressed in Escherichia coli cells. Mice immunized with TBI showed humoral and cellular immune responses to HIV-1. Anti-TBI antibodies displayed HIV-1 neutralizing activity. These new approaches offer promise in the development of new effective vaccines.

Abstract
Earlier, we developed an expression vector allowing exposure of short peptides on the surface of bacteriophage M13. It was used to obtain a recombinant phage carrying an antigenic determinant of HIV1 p17 Gag protein. Immunoglobulin elicited by immunizing rabbits with the phage reacted with the 17-kDa core protein of the virus and with its polyprotein precursor, p55, on Western blots of HIV1 viral proteins. The results of present experiments may be useful in vaccine development.

Abstract
Foreign DNA fragments were inserted into filamentous phage gene VIII to create hybrid B-proteins with foreign sequences in the amino terminus. The hybrid proteins are incorporated into the virions which retain viability and infectivity. Virions with hybrid B-proteins have the same contour length and the same number of B-protein molecules as virions with natural B-proteins. It was shown that for one of hybrid B-proteins the position of the processing site had changed.
