Abstract
INTRODUCTION Hepatitis C is a liver disease with high chronicity, the cause of cirrhosis and hepatocarcinoma. The main obstacle to controlling hepatitis C is the lack of vaccines. The aim of the work was to compare the immunogenic activity of nonstructural recombinant proteins NS3, NS4 and NS5B of hepatitis C virus (HCV) as components of a subunit candidate vaccine and to analyze the adjuvant properties of two available commercial drugs, polymuramil and pyrogenalum. MATERIALS AND METHODS BALB/c, DBA/2J and C57BL/6 mice were immunized with nonstructural proteins without adjuvants or with polymuramyl (NOD1 and NOD2 agonist) and pyrogenalum (TLR-4 agonist). The activity of antibodies was determined in ELISA, the cellular response - by antigen-specific lymphocyte proliferation and by production of IFN-γ in vitro. RESULTS Recombinant proteins showed different immunogenicity. NS4 induced antibodies more efficiently than NS3 and NS5B. Significant differences were found in the immune response of three inbred lines mice: the level of IFN-γ in BALB/c and DBA/2J mice induced by NS5B protein was 30 times higher than in C57Bl/6 mice. In contrast, the induction of antibodies in BALB/c mice was lower than in C57Bl/6 and DBA/2J. Polymuramil did not increase the humoral response to NS5B and enhanced the cellular response only in C57BL/6 mice. The combined use of polymuramil with pyrogenalum significantly increased both the humoral and cellular response of mice to all recombinant HCV proteins. CONCLUSION Different immunogenic properties and different functions of recombinant non-structural HCV proteins indicate the feasibility of their combined inclusion in subunit vaccines. It was established for the first time that immunization with HCV proteins with a complex adjuvant (polymuramyl + pyrogenalum) has a synergistic effect, significantly exceeding the effect of each of them separately.

Abstract
Exosomes are extracellular vesicles of endosomal origin, with a bilayer membrane, 30160 nm in diameter. Exosomes are released from cells of different origins and are detected in various body fluids. They contain nucleic acids, proteins, lipids, metabolites and can transfer the contents to recipient cells. Exosome biogenesis involves cellular proteins of the Rab GTPase family and the ESCRT system, which regulate budding, vesicle transport, molecule sorting, membrane fusion, formation of multivesicular bodies and exosome secretion. Exosomes are released from cells infected with viruses and may contain viral DNA and RNA, as well as mRNA, microRNA, other types of RNA, proteins and virions. Exosomes are capable of transferring viral components into uninfected cells of various organs and tissues. This review analyzes the impact of exosomes on the life cycle of widespread viruses that cause serious human diseases: human immunodeficiency virus (HIV-1), hepatitis B virus, hepatitis C virus, SARS-CoV-2. Viruses are able to enter cells by endocytosis, use molecular and cellular pathways involving Rab and ESCRT proteins to release exosomes and spread viral infections. It has been shown that exosomes can have multidirectional effects on the pathogenesis of viral infections, suppressing or enhancing the course of diseases. Exosomes can potentially be used in noninvasive diagnostics as biomarkers of the stage of infection, and exosomes loaded with biomolecules and drugs - as therapeutic agents. Genetically modified exosomes are promising candidates for new antiviral vaccines.

Abstract
Hepatitis C virus (HCV) is one of the basic culprits behind chronic liver disease, which may result in cirrhosis and hepatocarcinoma. In spite of the extensive research conducted, a vaccine against HCV has not been yet created. We have obtained human mesenchymal stem cells (hMSCs) and used them for expressing the HCV NS5A protein as a model vaccination platform. Sixteen hMSC lines of a different origin were transfected with the pcNS5A-GFP plasmid to obtain genetically modified MSCs (mMSCs). The highest efficiency was obtained by the transfection of dental pulp MSCs. C57BL/6 mice were immunized intravenously with mMSCs, and the immune response was compared with the response to the pcNS5A-GFP plasmid, which was injected intramuscularly. It was shown that the antigen-specific lymphocyte proliferation and the number of IFN-γ-synthesizing cells were two to three times higher after the mMSC immunization compared to the DNA immunization. In addition, mMSCs induced more CD4+ memory T cells and an increase in the CD4+/CD8+ ratio. The results suggest that the immunostimulatory effect of mMSCs is associated with the switch of MSCs to the pro-inflammatory phenotype and a decrease in the proportion of myeloid derived suppressor cells. Thus, the possibility of using human mMSCs for the creation of a vaccine against HCV has been shown for the first time.

Abstract
INTRODUCTION A vaccine against hepatitis C has not yet been developed. Recombinant proteins and plasmids encoding hepatitis C virus (HCV) proteins, the components of candidate vaccines, induce a weak immune response and require the use of adjuvants. The aim of the work was to study the adjuvant action of an aqueous solution of fullerene C60 during immunization of mice with HCV recombinant protein NS5B (rNS5B) that is an RNA-dependent RNA polymerase, or with NS5B-encoding pcNS5B plasmid. MATERIALS AND METHODS An aqueous solution of dispersed fullerene (dnC60) was obtained by ultrafiltration. C57BL/6 mice were immunized with rNS5B subcutaneously, pcNS5B intramuscularly mixed with different doses of dnC60 three times, then the humoral and cellular response to HCV was evaluated. RESULTS Mice immunization with rNS5B in a mixture with dnC60 at doses of 250 g/mouse significantly induced humoral response: a dose-dependent increase in IgG1 antibody titers was 720 times higher than in the absence of fullerene. There was no increase in the cellular response to rNS5B when administered with dnC60. The humoral response to DNA immunization was weak in mice of all groups receiving pcNS5B. The cellular response was suppressed when the plasmid was injected in a mixture with dnC60. CONCLUSIONS Dispersed fullerene dnC60 is a promising adjuvant for increasing the immunostimulating activity of weakly immunogenic proteins including surface and other HCV proteins, important for a protective response. Further research is needed to enhance the ability of dnC60 to boost the cellular immune response to the components of the candidate vaccine.

Abstract
Almost all people become infected with herpes viruses, including herpes simplex virus type 1 (HSV-1), during their lifetime. Typically, these viruses persist in a latent form that is resistant to all available antiviral medications. Under certain conditions, such as immunosuppression, the latent forms reactivate and cause disease. Moreover, strains of herpesviruses that are drug-resistant have rapidly emerged. Therefore, it is important to develop alternative methods capable of eradicating herpesvirus infections. One promising direction is the development of CRISPR/Cas systems for the therapy of herpesvirus infections. We aimed to design a CRISPR/Cas system for relatively effective long-term and safe control of HSV-1 infection. Here, we show that plasmids encoding the CRISPR/Cas9 system from Streptococcus pyogenes with a single sgRNA targeting the UL30 gene can completely suppress HSV-1 infection of the Vero cell line within 6 days and provide substantial protection within 9 days. For the first time, we show that CRISPR/CasX from Deltaproteobacteria with a single guide RNA against UL30 almost completely suppresses HSV-1 infection of the Vero cell line for 3 days and provides substantial protection for 6 days. We also found that the Cas9 protein without sgRNAs attenuates HSV-1 infection. Our results show that the developed CRISPR/Cas systems are promising therapeutic approaches to control HSV-1 infections.

Abstract
Human cytomegalovirus (HCMV) DNA and proteins are often detected in malignant tumors, warranting studies of the role that HCMV plays in carcinogenesis and tumor progression. HCMV proteins were shown to regulate the key processes involved in tumorigenesis. While HCMV as an oncogenic factor just came into focus, its ability to promote tumor progression is generally recognized. The review discusses the viral factors and cell molecular pathways that affect the resistance of cancer cells to therapy. CMV inhibits apoptosis of tumor cells, that not only promotes tumor progression, but also reduces the sensitivity of cells to antitumor therapy. Autophagy was found to facilitate either cell survival or cell death in different tumor cells. In leukemia cells, HCMV induces a "protective" autophagy that suppresses apoptosis. Viral factors that mediate drug resistance and their interactions with key cell death pathways are necessary to further investigate in order to develop agents that can restore the tumor sensitivity to anticancer drugs.

Abstract
Therapeutic enzymes used for the treatment of a wide range of human disorders often suffer from suboptimal pharmacokinetics and stability. Engineering approaches such as encapsulation in micro- and nanocarriers, and replacements of amino acid residues of the native enzyme provide significant potential for improving the performance of enzyme therapy. Here, we develop a nanodelivery system on the base of polyion complex vesicles (PICsomes) that includes methionine γ-lyase (MGL) as a therapeutic enzyme. We have two strategies for using the enzyme: first, methionine γ-lyase is an anticancer agent removing l-methionine from plasma, second, the binary system methionine γ-lyase/S-alk(en)yl-l-cysteine sulfoxides is effective in enzyme prodrug therapy (EPT). Various lengths polymers were synthesized, and two mutant forms of the enzyme were used. The catalytic and pharmacokinetic parameters of the nanoformulations were investigated. The catalytic efficiencies of encapsulated enzymes were comparable to that of native enzymes. Pharmacokinetic analysis has shown that inclusion into PICsomes increases half-life of the enzymes, and they can be safely administered in vivo. The results suggest the further use of encapsulated MGLs for EPT and anticancer therapy, and this strategy could be leveraged to improve the efficiency of enzyme-based therapies for managing serious human diseases.

Abstract
Despite extensive research, there is still no vaccine against the hepatitis C virus (HCV). The aim of this study was to investigate whether MSCs can exhibit adjuvant properties during DNA vaccination against hepatitis C. We used the pcNS3-NS5B plasmid encoding five nonstructural HCV proteins and MSCs derived from mice bone marrow. Five groups of DBA mice were immunized with the plasmid and/or MSCs in a different order. Group 1 was injected with the plasmid twice at intervals of 3 weeks; Group 2 with the plasmid, and after 24 h with MSCs; Group 3 with MSCs followed by the plasmid the next day; Group 4 with only MSCs; and Group 5 with saline. When the MSCs were injected prior to DNA immunization, the cell immune response to HCV proteins assessed by the level of IFN-γ synthesis was markedly increased compared to DNA alone. In contrast, MSCs injected after DNA suppressed the immune response. Apparently, the high level of proinflammatory cytokines detected after DNA injection promotes the conversion of MSCs introduced later into the immunosuppressive MSC2. The low level of cytokines in mice before MSC administration promotes the high immunostimulatory activity of MSC1 in response to a DNA vaccine. Thus, when administered before DNA, MSCs are capable of exhibiting promising adjuvant properties.

Abstract
Despite the development of efficient anti-human immunodeficiency virus-1 (HIV-1) therapy, HIV-1 associated pathogens remain a major clinical problem. Human cytomegalovirus (CMV) is among the most common HIV-1 copathogens and one of the main causes of persistent immune activation associated with dysregulation of the immune system, cerebrovascular and cardiovascular pathologies, and premature aging. Here, we report on the development of dual-targeted drugs with activity against both HIV-1 and CMV. We synthesized seven compounds that constitute conjugates of molecules that suppress both pathogens. We showed that all seven compounds exhibit low cytotoxicity and efficiently inhibited both viruses in cell lines. Furthermore, we chose a representative compound and demonstrated that it efficiently suppressed replication of HIV-1 and CMV in human lymphoid tissue ex vivo coinfected with both viruses. Further development of such compounds may lead to the development of dual-targeted anti-CMV/HIV-1 drugs.

Abstract
Hepatitis C virus (HCV) is one of the main triggers of chronic liver disease. Despite tremendous progress in the HCV field, there is still no vaccine against this virus. Potential vaccines can be based on its recombinant proteins. To increase the humoral and, especially, cellular immune response to them, more effective adjuvants are needed. Here, we evaluated a panel of compounds as potential adjuvants using the HCV NS5B protein as an immunogen. These compounds included inhibitors of polyamine biosynthesis and urea cycle, the mTOR pathway, antioxidants, and cellular receptors. A pronounced stimulation of cell proliferation and interferon-γ (IFN-γ) secretion in response to concanavalin A was shown for antioxidant N-acetylcysteine (NAC), polyamine biosynthesis inhibitor 2-difluoromethylornithine (DFMO), and TLR9 agonist CpG ODN 1826 (CpG). Their usage during the immunization of mice with the recombinant NS5B protein significantly increased antibody titers, enhanced lymphocyte proliferation and IFN-γ production. NAC and CpG decreased relative Treg numbers; CpG increased the number of myeloid-derived suppressor cells (MDSCs), whereas neither NAC nor DFMO affected MDSC counts. NAC and DFMO suppressed NO and interleukin 10 (IL-10) production by splenocytes, while DFMO increased the levels of IL-12. This is the first evidence of immunomodulatory activity of NAC and DFMO during prophylactic immunization against infectious diseases.

Abstract
Herpes simplex viruses 1 and 2 (HSV-1 and HSV-2) infect almost all organs and tissues, cause genital herpes-the most common sexually transmitted disease-disorders of the central nervous system (CNS), and lead to severe complications in children. Despite the available drugs, the incidence of HSV-1/2 continues to rise. None of the prophylactic vaccine candidates have shown a protective effect in trials nor approval for use in clinical practice. We have investigated the protective properties of mesenchymal stem cells (MSC) isolated from the bone marrow of mice. A comparative analysis of the protective response to the introduction of primary and modified MSCs (mMSC) was carried out using the plasmid containing gene of the HSV and an inactivated virus in a model of lethal HSV-1 infection in mice. mMSCs were obtained by transfection of the Us6 gene encoding glycoprotein D (gD) of the HSV, the plasmid contained the same gene. After twofold immunization with primary MSCs, the formation of antibodies interacting with the viral antigen (according to enzyme immunoassay data) and neutralizing the infectious activity of HSV-1 in the reaction of biological neutralization was observed in the peripheral blood of mice. In addition, the introduction of primary MSCs induced the production of interferon gamma (INF-γ) which is detected in the peripheral blood of mice. After infection with HSV-1, the immunized mice showed significantly increased titers of virus-specific antibodies, an increased level of IFNγ, and were completely protected from lethal HSV-1 infection. The protective effect of the other three immunogens was lower and did not exceed 50-65%. Considering the wide availability of MSCs, the proven safety of intravenous administration, and the results obtained in this work on the ability to induce innate, adaptive and protective immunity to HSV-1, MSCs can be considered a promising basis for the development of new cellular vaccines for the prevention of herpesvirus and other viral infections.

Abstract
This review presents the data on the spreading of all known human herpesviruses (НHVs) in female urogenital tract. According to the WHO almost 500 million people worldwide suffer from genital infection caused by НHVs. НHVs were detected in various inflammatory diseases of female upper and lower genital tract (vaginitis and cervicitis), in extrauterine pregnancy (in fallopian tubes), in infertility (cervical channel, endometrium and ovaries). Herpes simplex virus 1 (HSV‑1) was identified for the first time in oocytes after failed in vitro fertilization (IVF). НHVs produce negative effect on the entire reproductive process from conception to childbirth. It was established that HSV, cytomegalovirus (CMV) and human herpesvirus 6 (HHV-6) markedly increase the risk of spontaneous abortion, preterm birth and stillbirth. Intrauterine НHV infection is a major cause of congenital malformations. Data on humoral and cell immunity in genital herpesvirus infections (НHVI) are also reviewed. Intravaginal HSV‑2 infection changes cell composition of vaginal mucosa, i.e., together with cells mobilized from the blood, protective role is performed by resident memory T‑cells (TRM), natural killer cells (NK‑cells) and regulatory T‑cells (Treg) whose function consists in maintaining the balance of the activities of lymphocytes. Constant НHVI spreading is largely explained by transition of primary infection to potentially reactivating latent form, since latent virus is unavailable to immune recognition and medicines. The genome editing system CRISPR/Cas9 can recognize and modify not only active but also latent viruses. The promising pilot results with the use of this system offer the possibility of developing innovative technologies for НHV elimination and НHVI eradication.

Abstract
Mutations arising in influenza viruses that have undergone immune pressure may promote a successful spread of mutants in nature. In order to evaluate the variability of nonpathogenic influenza virus A/duck/Moscow/4182-C/2010(H5N3) and to determine the common epitopes between it and highly pathogenic H5N1 avian influenza viruses (HPAIV), a set of escape mutants was selected due to action of MABs specific against A/chicken/Pennsylvania/8125/83(H5N2), A/Vietnam/1203/04(H5N1) and A/duck/Novosibirsk/56/05(H5N1) viruses. The complete genomes of escape mutants were sequenced and amino acid point mutations were determined in HA, NA, PA, PB1, PB2, M1, M2, and NP proteins. Comprehensive analysis of the acquired mutations was performed using the Influenza Research Database (https://www.fludb.org) and revealed that all mutations were located inside short linear epitopes, in positions characterized by polymorphisms. Most of the mutations found were characterized as substitutions by predominant or alternative amino acids existing in nature. Antigenic changes depended only on substitutions at positions 126, 129, 131, 145 and 156 of HA (H3 numbering). The positions 126, 145 and 156 were common for HA/H5 of different phylogenetic lineages of H5N1 HPAIV (arisen from A/goose/Guangdong/1/96) and low pathogenic American and Eurasian viruses. Additionally, mutation S145P increased the temperature of HA heat inactivation, compared to wild-type, as was proved by reverse genetics. Moreover, nonpathogenic A/duck/Moscow/4182-C/2010(H5N3) and H5N1 HPAI viruses have the same structure of short linear epitopes in HA (145-157) and internal proteins (PB2: 186-200, 406-411; PB1: 135-143, 538-546; PA: 515-523; NP: 61-68; M1: 76-84; M2: 45-53). These facts may indicate that H5 wild duck nonpathogenic virus could be used as vaccine against H5N1 HPAIV.

Abstract
INTRODUCTION Respiratory syncytial virus (RSV) is the most common cause of lower respiratory tract infections in infants and the elderly. The absence of a wide range of therapeutic drugs and vaccines indicates to the high relevance of the development of new effective drugs for the prevention and treatment of RSV infections. PURPOSE to obtain highly active and specific monoclonal antibodies (MAbs) capable of detecting RSV in infected cells and neutralizing the infectious activity of the virus in vitro. MATERIAL AND METHODS RSV reference strains of group A 2 subgroups (A2 and Long) were propagated in HEp-2 and MA-104 cell lines, respectively. Mice were immunized with purified RSV A2 virus. MAbs were obtained using hybridoma technology. RESULTS A panel of 6 MAbs reacting with RSV strains А2 and Long has been obtained. Four MAbs were IgG (IgG2a or IgG2b subtype), two MAbs were IgM. All MAbs reacted with RSV F-protein in immunochemical tests. The MAbs actively reacted with RSV in ELISA, in immufluorescence and peroxidase staining of infected cells, and in immunodot test. Five out of 6 MAbs neutralized of RSV in cell culture. Different properties of MAbs suggest that they target different antigenic sites of F-protein. DISCUSSION Comparative analysis suggests that the obtained MAbs can be used for the development of diagnostic preparations, for RSV detection in clinical materials and confirmation of infection etiology by rapid culture method. CONCLUSION High activity and specificity of MAbs indicate that they can serve as a basis for development vaccines and preventive medicines.

Abstract
Results obtained showed that infection with HCMV prevented the death of THP-1 cells treated with DOX in both active and latent forms of infection. In the presence of mTOR inhibitors (rapamycin and Torin2), the sensitivity of the infected cells to DOX was restored. Rapamycin inhibited the expression of the HCMV protein IE1-p72 and increased sensitivity to DOX. Molecular targets for the creation of new drugs for the treatment of leukemia in patients infected with HCMV were determined.

Abstract
A set of AT-specific fluorescent dimeric bisbenzimidazoles DBPA(n) with linkers of different lengths bound to DNA in the minor groove were synthesized and their genetic, virological, and biochemical studies were performed. The DBPA(n) were shown to be effective inhibitors of the histon-like protein H-NS, a regulator of the DNA transcription factor, as well as of the Aliivibrio logei Quorum Sensing regulatory system in E. coli cells. Their antiviral activity was tested in model cell lines infected with herpes simplex virus type I. Also, it was found that DBPA(n) could inhibit catalytic activities of HIV-1 integrase at low micromolar concentrations. All of the dimeric bisbenzimidazoles DBPA(n) manifested fluorescent properties, were well soluble in water, nontoxic up to concentrations of 200 µM, and could penetrate into nuclei followed by binding to DNA.

Abstract
Hepatitis C virus (HCV) is one of the major causes of chronic liver disease and leads to cirrhosis and hepatocarcinoma. Despite extensive research, there is still no vaccine against HCV. In order to induce an immune response in DBA/2J mice against HCV, we obtained modified mouse mesenchymal stem cells (mMSCs) simultaneously expressing five nonstructural HCV proteins (NS3-NS5B). The innate immune response to mMSCs was higher than to DNA immunization, with plasmid encoding the same proteins, and to naïve unmodified MSCs. mMSCs triggered strong phagocytic activity, enhanced lymphocyte proliferation, and production of type I and II interferons. The adaptive immune response to mMSCs was also more pronounced than in the case of DNA immunization, as exemplified by a fourfold stronger stimulation of lymphocyte proliferation in response to HCV, a 2.6-fold higher rate of biosynthesis, and a 30-fold higher rate of secretion of IFN-γ, as well as by a 40-fold stronger production of IgG2a antibodies to viral proteins. The immunostimulatory effect of mMSCs was associated with pronounced IL-6 secretion and reduction in the population of myeloid derived suppressor cells (MDSCs). Thus, this is the first example that suggests the feasibility of using mMSCs for the development of an effective anti-HCV vaccine.

Abstract
Here we report the Friedel-Crafts arylation of chlorofullerenes C60Cl6 and C70Cl8 with thiophene-based methyl esters. While C60Cl6 formed expected Cs-C60R5Cl products, C70Cl8 demonstrated a tendency for both substitution of chlorine atoms and addition of an extra thiophene unit, thus forming Cs-C70R8 and C1-C70R9H compounds. The synthesized water-soluble C60 and C70 fullerene derivatives with thiophene-based addends demonstrated high activity against a broad range of viruses, including human immunodeficiency virus, influenza virus, cytomegalovirus, and herpes simplex virus. The record activity of C70 fullerene derivatives against herpes simplex virus together with low toxicity in mice makes them promising candidates for the development of novel non-nucleoside antiherpetic drugs.

Abstract
The objective of this study was to evaluate immunoregulatory and protective potential of mesenchymal stem cells (MSC) in a mouse model of lethal HSV1 infection. MSC were isolated from bone marrow of DBA mice and cultured in flasks with DMEM containing 10% FBS, insulin, transferrin, selenite, fbroblast growth factor, glutaminе and gentamicin. Antiviral activity was tested on HSV1-infected Vero cells. In vivo experiments were performed on DBA mice divided into 5 groups (10 animals each): group 1, intact (naïve) mice; group 2, intravenous (iv) MSC injection; group 3, ntraperitoneal infection with 20 LD50 HSV1 followed by MSC injection; group 4, HSV1 infection followed by acyclovir (ACV) injection; group 5, HSV1 infection and iv injection of saline. Isolated cells were consistent with MSC morphologically, by adhesive ability and surface receptors. Conditioned media from MSC collected after 4-5 passages inhibited HSV1 infection in vitro by 64-70% and contained IL-6 and TNF-α, whose concentrations were 5- and 20-fold higher, respectively, than in the control. MSC and ACV injections protected 70% and 60% of DBA mice, respectively, compared with the control (group 5, 10% survival). High activity of virus neutralizing anti-HSV1 antibodies and activation of T cell proliferation were observed in survived mice from group 3. Serum levels of IL-6 and TNF-α in these mice were lower and that of INF-γ much higher than in agonizing animals of this group (Р<0.05). These fndings indicate that MSC therapy is a prospective approach to the development of new effective management of generalized HSV1 infection.

Abstract
INTRODUCTION After the emergence and spread of pandemic H1N1 viruses in 2009, antigenic epitopes recognized by neutralizing antibodies against the hemagglutinin of influenza A/Moscow/01/09(H1N1)pdm09 viruses were studied. PURPOSE The purpose of the study was to obtain readapted variants of the virus from a low-virulent escapemutant that has an increased affinity of the avian and the human types cellular receptors compared to the wild type and the comparative study of their antigenic and receptor specificity. MATERIAL AND METHODS Viruses were accumulated in 10-day-old chicken embryos. The MAB panel against HA of influenza virus strain A/IIV-Moscow/01/09(H1N1)sw1 was used in the form of ascites fluids from mice. Immunization of mice, HI testing, elution of viruses from chicken erythrocytes, PCR and sequencing of readapted variants were performed by standard methods. RESULTS The amino acid substitution A198E acquired in the process of readaptation leads to changes in the antigenic specificity. A correlation was found between a decrease in virulence of a low-virulent escape mutant associated with the substitution D190N in the hemagglutinin molecule and an increase in the hemagglutinating titer to inhibitors in normal mouse serum. Viruses with low affinity of cellular receptor analogs and carrying amino acid substitutions have an increased ability to elute from chicken erythrocytes. DISCUSSION The results discuss the effect of mutations in the HA molecule of the influenza A(H1N1) pdm09 virus to the change in antigen specificity; virulence for mice, adsorption-elution at cellular receptors. CONCLUSION A comparative study of the antigenic specificity and receptor-binding activity of the escape mutants was conducted for the hemagglutinin of the influenza virus A/Moscow/01/2009 (H1N1)swl, and the readapted variants obtained for one of the escape mutants with reduced virulence for mouse. Monitoring the pleiotropic effect of mutations in the hemagglutinin H1 molecule is necessary to predict variants of the virus with pandemic potential.

Abstract
INTRODUCTION The etiology of abacterial CP/CPPS (category III) has not been studied enough. Currently, there is no gold standard of diagnostic study and optimal treatment algorithm. AIM The aim of our study was to study three human herpes viruses (HHV) in clinical samples from patients with inflammatory diseases of urogenital tract and to evaluate the efficiency of proposed treatment algorithm for abacterial CP/CPPS. MATERIALS AND METHODS The biological samples from the urogenital tract (urethral swab, ejaculate and expressed prostatic secretions) from 101 patients with category III CP/CPPS were studied. Quantitative analysis of HHV DNA (CMV, EBV and HHV-6) was performed by PCR. RESULTS HHV DNA was detected in 38/101 patients (37.6%) in Group 1. Among the detected viral types, HHV-6 was the most common (52%). Analysis of biological samples form the three sources revealed that viral DNA was determined in urethral swab in concentration of 3,703,900 copies/ml. In Group 2, viral DNA was not detected in 63 patients. Evaluation of results of the standard treatment in HHV-negative patients (n=63) and antibiotic-free scheme, including the immunoregulatory drug Viferon, in HHV-positive patients (n=38) showed that the number of HHV-positive samples after treatment decreased by 54.3%. In addition, severity of all symptoms according to NIH-CPSI scale significantly decreased in both groups (p<0.0001). There was an improvement in all clinical symptoms in Group 1 by 47.9%, especially for pain + urination (52%). It should be noted that a positive response to treatment, which was confirmed by the changes in total score of NIH-CPSI scale, was noted in all patients in Group 1. CONCLUSION Detection of herpes viruses in the urogenital tract of patients with abacterial CP/CPPS suggests possible role of viral infections in its etiology. The comparative analysis of the results of standard treatment including antiviral, immunomodulatory and antioxidant drugs showed that the use of complex therapy without antibiotics allowed to eliminate or significantly reduce the concentration of viruses in urogenital tract, as well as significantly reduce the clinical manifestations of abacterial CP/CPPS.

Abstract
We report an "inversed" Arbuzov reaction of the fullerene derivatives C60Ar5Cl with trialkyl phosphites P(OR)3 producing alkylated fullerene derivatives C60Ar5R (R = Me, Et, iPr, nBu) with almost quantitative yields. This reaction provides a convenient synthetic route for the preparation of a large variety of functionalized fullerene derivatives with tailored properties, e.g. water-soluble compounds demonstrating promising antiviral activities against HCMV, HSV1, HIV and several influenza virus strains.

Abstract
Herpesviruses are widespread in the human population. Herpes simplex virus type 1 (HSV1) alone infects more than 3.7 billion people. In most of these, the virus establishes a latent form resistant to the action of all antiviral drugs. Moreover, completely drug-resistant strains of herpesviruses are known, which has prompted the search for alternative approaches to the treatment of herpesviruses, including genome editing with prokaryotic CRISPR/Cas. The CRISPR/Cas9 system of Streptococcus pyogens effectively suppresses HSV1 infection when expressed from genome-integrated lentiviral vectors. However, there are concerns about the safety of this approach. Here we describe the system built upon the plasmid-encoded CRISPR/Cas9 targeted against UL52 and UL29 genes of the HSV1 primase-helicase complex. The construct was transfected into Vero cells with no significant cytotoxic effects detected. Complete suppression of HSV1 infection within two days was observed, raising the possibility that the proposed plasmid-expressed CRISPR/Cas9 system may be used for the screening of genes important for the HSV1 life cycle and for development of novel strategies for targeted therapy of herpesvirus infections.

Abstract
Leukemic cells from different patients exhibit different sensitivity to anticancer drugs including doxorubicin (DOX). Resistance to chemotherapy decreases efficacy of the treatment and promotes cancer recurrence and metastases. One of the approaches to overcome drug resistance includes E2F1-mediated regulation of the р73 protein that belongs to the р53 family. Its ΔNp73 isoform exhibits pro-oncogenic effects, and TAp73 - anti-oncogenic effects. Human cytomegalovirus (HCMV), often found in tumors, suppresses pro-apoptotic pathways and E2F1/p73 in particular. The activity of E2F1 and p73 transcription factors is linked to metabolism of biogenic polyamines. Therefore, it could be suggested that compounds that target polyamine-metabolizing enzymes can sensitize HCMV-infected hematological malignancies to doxorubicin. Here we report that HCMV infection of ТНР-1 monocytic leukemic cells considerably elevates E2F1 levels and shifts the balance between the р73 isoforms towards ΔNp73 leading to survival of DOX-treated leukemic cells. In contrast, MDL72.527, an inhibitor of polyamine catabolism, decreases ΔNp73/ТАр73 ratio and thus restores sensitivity of the cells to DOX. Our findings indicate the combination of doxorubicin and MDL72.527 may present a novel strategy for therapy of leukemia in patients with and without HCMV infection.

Abstract
The search for new adjuvants remains the critical task for the creation of hepatitis C vaccines due to the weak immunogenicity of biotechnological products. When immunizing mice with the recombinant proteins NS3 and NS5B of the hepatitis C virus (HCV), the adjuvant activity of three immunomodulators was compared. Phosprenyl® on the basis of polyprenyl phosphate (PPP), chemically synthesized analogue of the bacterial cell wall glucosaminyl muramyl dipeptide (GMDP), and IFN-α recombinant protein were tested. GMDP increased the activity of IgG1 antibodies 4-6 times but did not stimulate the production of IFN-γ; IFN-α has not shown any adjuvant properties. The introduction of recombinant HCV proteins together with PPP in low doses increased the activity of IgG2a isotype antibodies 4-7 times and increased IFN-γ secretion 3 times. Thus, it was first shown that PPP polarizes the immune response to Th1-type and is a promising adjuvant for the development of a vaccine against hepatitis C.

Abstract
Antiviral activity of new AТ-specific fluorescent symmetric dimeric bisbenzimidazoles of DBА(n) series was assessed in the cell models of infections caused by type 1 herpes simplex virus (HSV1) and human cytomegalovirus (CMV). In DBA(n) molecules bisbenzimidazole fragments are bound to an oligomethylene liner with varied number of methylene groups in the linker (n = 1, 3, 5, 7, 9, 11). In contrast to DB(n) dimeric bisbenzimidazoles, in DBA(n) series terminal fragments of macromolecules contain N-dimethylaminopropylcarboxamide groups instead of N-methylpiperazine groups. DBА(n) compounds better dissolve in water, pass across plasma and nuclear membrane, and stain DNA in living cells. DBA(1) and DBA(7) produced therapeutic effects in HSV1 infection; DBA(7) completely suppressed the infection. DBA(11) displayed in vitro therapeutic activity in HSV1 and CMV infections. In addition, DBA(7) and DBA(1) showed microbicidal activity. Thus, DBA(11), which is active against two viruses causing severe diseases with serious health consequences for immunodeficient individuals, should be further investigated. High antiviral activity of DBA(7) in all test models indicates that this compound is a promising active agent for innovative antiviral drugs.

Abstract
The hepatitis C virus (HCV) causes chronic liver disease leading to fibrosis, cirrhosis, and hepatocellular carcinoma. HCV infection triggers various types of cell death which contribute to hepatitis C pathogenesis. However, much is still unknown about the impact of viral proteins on them. Here we present the results of simultaneous immunocytochemical analysis of markers of apoptosis, autophagy, and necrosis in Huh7.5 cells expressing individual HCV proteins or their combinations, or harboring the virus replicon. Stable replication of the full-length HCV genome or transient expression of its core, Е1/Е2, NS3 and NS5B led to the death of 20-47% cells, 72 h posttransfection, whereas the expression of the NS4A/B, NS5A or NS3-NS5B polyprotein did not affect cell viability. HCV proteins caused different impacts on the activation of caspases-3, -8 and -9 and on DNA fragmentation. The structural core and E1/E2 proteins promoted apoptosis, whereas non-structural NS4A/B, NS5A, NS5B suppressed apoptosis by blocking various members of the caspase cascade. The majority of HCV proteins also enhanced autophagy, while NS5A also induced necrosis. As a result, the death of Huh7.5 cells expressing the HCV core was induced via apoptosis, the cells expressing NS3 and NS5B via autophagy-associated death, and the cells expressing E1/E2 glycoproteins or harboring HCV the replicon via both apoptosis and autophagy.

Abstract
Hepatitis C virus (HCV) induces the expression of the genes of proinflammatory cytokines, the excessive production of which may cause cell death, and contribute to development of liver fibrosis and hepatocarcinoma. The relationship between cytokine production and metabolic disorders in HCV-infected cells remains obscure. The levels of biogenic polyamines, spermine, spermidine, and their precursor putrescine, may be a potential regulator of these processes. The purpose of the present work was to study the effects of the compounds which modulate biogenic polyamines metabolism on cytokine production and HCV proteins expression. Human hepatocarcinoma Huh7.5 cells have been transfected with the plasmids that encode HCV proteins and further incubated with the following low-molecular compounds that affect different stages of polyamine metabolism: (1) difluoromethylornithine (DFMO), the inhibitor of ornithine decarboxylase, the enzyme that catalyzes the biosynthesis of polyamines; (2) N,N'-bis(2,3-butane dienyl)-1,4-diaminobutane (MDL72.527), the inhibitor of proteins involved in polyamine degradation; and (3) synthetic polyamine analog N^(I),N^(II)-diethylnorspermine (DENSpm), an inducer of polyamine degradation enzyme. The intracellular accumulation and secretion of cytokines (IL-6, IL-1β, TNF-α, and TGF-β) was assessed by immunocytochemistry and in the immunoenzyme assay, while the cytokine gene expression was studied using reverse transcription and PCR. The effects of the compounds under analysis on the expression of HCV proteins were analyzed using the indirect immunofluorescence with anti-HCV monoclonal antibodies. It has been demonstrated that, in cells transfected with HCV genes, DFMO reduces the production of three out of four tested cytokines, namely, TNF-α and TGF-β in cells that express HCV core, Е1Е2, NS3, NS5A, and NS5B proteins, and IL-1β in the cells that express HCV core, Е1Е2, and NS3 proteins. MDL72527 and DENSpm decreased cytokine production to a lesser extent. Incubation with DFMO led to a 28-32% decrease in the number of cells expressing NS5B or NS5A, both of which are key components of the HCV replication complex. The results obtained in the work indicate that a further detailed study of the antiviral activity of DFMO is required in order to assess its potential as an anti-hepatitis C therapeutic agent.

Abstract
Responses to human cytomegalovirus (HCMV) infection are largely individual and cell type specific. We investigated molecular profiles in 2 primary cell cultures of human fibroblasts, which are highly or marginally sensitive to HCMV infection, respectively. We screened expression of genes and microRNAs (miRs) at the early (3 hours) stage of infection. To assess molecular pathway activation profiles, we applied bioinformatic algorithms OncoFinder and MiRImpact. In both cell types, pathway regulation properties at mRNA and miR levels were markedly different. Surprisingly, in the infected highly sensitive cells, we observed a "freeze" of miR expression profiles compared to uninfected controls. Our results evidence that in the sensitive cells, HCMV blocks intracellular regulation of microRNA expression already at the earliest stage of infection. These data suggest somewhat new functions for HCMV products and demonstrate dependence of miR expression arrest on the host-encoded factors.

Abstract
Genital tract infection and inflammation may affect male fertility, causing germ and Sertoli cell loss. We determined if testicular cell transplantation is effective at repairing testicular injury induced by herpes simplex virus (HSV) orchitis. ROSA26 mice were used as donors and the recipients were C57BL/6 mice after HSV testicular inoculation; some of the recipients were treated with the antiviral drug acyclovir (ACV). ACV reduced the amount of HSV antigen in testes on Day 3 after transplantation and enhanced the efficacy of transplantation at Day 30. In recipient testes, donor Sertoli cells formed new seminiferous tubules; significantly more new tubules were observed in the testes of ACV-treated mice compared with mice not treated with ACV (17.8% vs 3.6%). Over half (50.4%) of new tubules in ACV-treated testes contained germ cells and round spermatids were detected in 14.2% of new tubules compared with 15.9% and 5.3% in testes not treated with ACV, respectively. At Day 150 the seminiferous epithelium was completely recovered in some donor tubules and elongated spermatids were observed inside it. Thus, our findings reveal the effectiveness of the combination of antiviral therapy with neonatal testis-cell transplantation for the restoration of spermatogenesis damaged by viral infection.

Abstract
Hepatitis C virus (HCV) is a widespread dangerous human pathogen. Up to 80% of HCV-infected individuals develop chronic infection, which is often accompanied by liver inflammation and fibrosis and, at terminal stages, liver cirrhosis and cancer. Treatment of patients with end-stage liver disease is often ineffective, and even patients with suppressed HCV replication have higher risk of death as compared with noninfected subjects. Therefore, investigating the mechanisms that underlie HCV pathogenesis and developing treatments for virus-associated liver dysfunction remain an important goal. The effect of individual HCV proteins on the production of proinflammatory and profibrotic cytokines in hepatocellular carcinoma Huh7.5 cells was analyzed in a systematic manner. Cells were transfected with plasmids encoding HCV proteins. Cytokine production and secretion was accessed by immunocytochemistry and ELISA of the culture medium, and transcription of the cytokine genes was assessed using reverse transcription and PCR. HCV proteins proved to differ in effect on cytokine production. Downregulation of interleukin 6 (IL-6) production was observed in cells expressing the HCV core, NS3, and NS5A proteins. Production of transforming growth factor β1 (TGF-β1) was lower in cells expressing the core proteins, NS3, or E1/E2 glycoproteins. A pronounced increase in production and secretion of tumor necrosis factor α (TNF-α) was observed in response to expression of the HCV E1/E2 glycoproteins. A higher biosynthesis, but a lower level in the cell culture medium, was detected for interleukin 1β (IL-1β) in cells harboring NS4 and IL-6 in cells expressing NS5В. The finding was possibly explained by protein-specific retention and consequent accumulation of the respective cytokines in the cell.

Abstract
The DNA of human herpesviruses (HHV), including the herpes simplex virus (HSV) and cytomegalovirus (CMV), is often identified in ejaculates of patients with urogenital diseases and infertility. At least a part of viral DNA is associated with cell fraction of ejaculate. However, it remains unclear how the semen is infected by the virus. It can be located in gametes or be capable of infecting mature germ cells, including motile sperm cells. In order to resolve this issue, interactions of the CMV and HSV with human sperm cells were studied using an original optimized model of the herpesviral infection of male gametes in vitro. The analysis of the immunofluorescent staining of gametes for viral antigens has shown that CMV infected 2% gametes, while HSV infected 17.26 ± 2.58% gametes. The fraction of progressively motile sperm cells contained 13.99 ± 4.64% infected cells. Localization of HSV was studied by the confocal microscopy. Sometimes, viral gB protein was found on sperm cell membrane. In addition, optical scanning of other cells has shown the intracellular localization of the viral proteins. In the majority of spermatozoa, the viral proteins were observed in the head and neck. In some cells, they were located in the middle piece or, rarely, in the equatorial segment. In general, after in vitro infection HSV antigens were located in the same areas of the sperm cells as in ejaculates from infected patients. According to DNA-DNA hybridization in situ, gametes containing HSV DNA accounted for 16.94 ± 5.28%, which is consistent with the results obtained in the immunofluorescence assay. It can be concluded that mature male gametes are infected by HHV in the genital tract, where the virus binds to the sperm cell membrane and enters the cell. Interaction of HHV with progressively motile sperm cells implies a vertical viral transmission upon fertilization and points to the necessity of testing ejaculate for herpesviruses infections.

Abstract
Infertility is an actual medical and social problem. In 50% of couples it is associated with the male factor and in more than 50% of cases the etiology of the infertility remains insufficiently understood. The goal of this work was to study the prevalence and to perform quantitative analysis of the human herpes viruses (HHV) and high carcinogenic risk papilloma viruses (HR HPV) in males with infertility, as well as to assess the impact of these infections on sperm parameters. Ejaculate samples obtained from 196 males fall into 3 groups. Group 1 included men with the infertility of unknown etiology (n = 112); group 2, patients who had female partners with the history of spontaneous abortion (n = 63); group 3 (control), healthy men (n = 21). HHV and HR HPV DNA in the ejaculates were detected in a total of 42/196 (21.4%) males: in 31 and 11 patients in groups 1 and 2, respectively (p > 0.05) and in none of healthy males. HHV were detected in 24/42; HR HPV, in 18/42 males (p > 0.05) without significant difference between the groups. Among HR HPV genotypes of the clade A9 in ejaculate were more frequent (14/18, p = 0.04). Comparative analysis of the sperm parameters showed that in the ejaculates of the infected patients sperm motility as well as the number of morphologically normal cells were significantly reduced compared with the healthy men. The quantification of the viral DNA revealed that in 31% of the male ejaculates the viral load was high: > 3 Ig10/100000 cells. Conclusion. The detection of HHV and HR HPV in the ejaculate is associated with male infertility. Quantification of the viral DNA in the ejaculate is a useful indicator for monitoring viral infections in infertility and for decision to start therapy.

Abstract
Changes associated with the resistance to physical and chemical factors in the hemagglutinin (HA) of influenza A viruses may play an important role in the selection of different influenza variants during circulation in nature. Here, we studied the escape mutants of influenza virus A/mallard/Pennsylvania/10218/84 (H5N2) that were selected by the monoclonal antibody. The escape mutant m4F11(4) carried a single amino acid substitution in large subunit (HA1) of the HA, S145P1, and two ones, m4G10(10) and m4G10(6), had additional amino acid changes in the small subunit (HA2), namely: L124F2 and L124F2 + N79D2, respectively. As it has been found the substitutions appeared in the HA2 of m4G(10) and m4G(6) viruses compensated negative effect of the S145P1 mutation and provided a significant increase in the viral replication ability at the early stage of infection in embryonated chicken eggs as well as in HA thermostability in comparison with m4F11(4) mutant. Phenotypic properties that provide advantages in the process of virus replication can play a role of the positive selection factor in viral population.

Abstract
The anticancer antibiotic doxorubicine (DOX) is highly toxic and induces functional complications in vital organs. The effect of DOX on normal cells has not been examined in sufficient detail, and the search for compounds reducing DOX toxicity did not lead to success so far. It has been suggested that DOX induces death of cancer cells via p53-dependent apoptosis, however, the information regarding the role of p73 protein, a member of p53 tumor suppressor family, is scanty. Cytomegalovirus (CMV) induces an antiapoptosis program that allows its replication until death of the target cell. Our objectives were to examine the effect of DOX on normal cells (human fibroblasts), analyze the ability of CMV-induced antiapoptosis program to reduce DOX toxicity, and to evaluate the involvement of p73 protein and its isoforms in the regulation of death of CMV-infected and DOX-treated cells. Within a 24-h time period DOX caused death of about 70% human embryonic lung fibroblasts (HELF) in cell culture, this parameter decreased significantly in CMV-infected DOX-treated HELF cells. TUNEL has shown that the number of cells with DNA fragmentation decreases from 5.2% under the effect of DOX to 3.2% (P < 0.05) after combined CMV-DOX treatment. Analysis of mitotic figures revealed that DOX causes accumulation of mitotic cells, which was not observed in CMV-infected DOX-treated cells. PCR analysis of mRNA of two p73 protein isoforms (TAp73 and dNp73) has shown that in uninfected cells the expression of TAp73 isoform was low, while in CMV-infected cells level of TAp73 was significant and expression of dNp73 was demonstrated for the first time. Expression of TAp73 associated with lack of mitosis block. The activation of caspases 8, 9 and 3 in CMV-infected cells was registered but cell death was not, however, as massive as that caused by DOX. From these findings it can be concluded that CMV attenuates DOX-related damage to normal cells. It can be suggested that induction of TAp73 and dNp73 isoforms provides conditions for reduction of DOX effect which leads to DNA damage and death of normal cells.

Abstract
Pseudotyped viruses bearing the glycoprotein(s) of a donor virus over the nucleocapsid core of a surrogate virus are widely used as safe substitutes for infectious virus in virology studies. Retroviral particles pseudotyped with influenza A virus glycoproteins have been used recently for the study of influenza hemagglutinin and neuraminidase-dependent processes. Here, we report the development of vesicular-stomatitis-virus-based pseudotypes bearing the glycoproteins of influenza A virus. We show that pseudotypes bearing the hemagglutinin and neuraminidase of H5N1 influenza A virus mimic the wild-type virus in neutralization assays and sensitivity to entry inhibitors. We demonstrate the requirement of NA for the infectivity of pseudotypes and show that viruses obtained with different NA proteins are significantly different in their transduction activities. Inhibition studies with oseltamivir carboxylate show that neuraminidase activity is required for pseudovirus production, but not for the infection of target cells with H5N1-VSV pseudovirus. The HA-NA-VSV pseudoviruses have high transduction titers and better stability than the previously reported retroviral pseudotypes and can replace live influenza virus in the development of neutralization assays, screening of potential antivirals, and the study of different HA/NA reassortants.

Abstract
The goal of this work was to analyze the antigenic structure of the hemagglutinin (HA) of the pandemic influenza virus A(H1N1)pdm09 using monoclonal antibodies (MAbs) and to develop a sandwich ELISA for identification of pandemic strains. Competitive ELISA demonstrated that 6 MAbs against HA of the pandemic influenza A/ IIV-Moscow/01/2009 (H1N1)pdm09 virus identified six epitopes. Binding of MAbs with 22 strains circulating in Russian Federation during 2009-2012 was analyzed in the hemagglutination-inhibition test (HI). The MAbs differed considerably in their ability to decrease the HI activity of these strains. MAb 5F7 identified all examined strains; MAbs 3A3 and 10G2 reacted with the majority of them. A highly sensitive sandwich ELISA was constructed based on these three MAbs that can differentiate the pandemic influenza strains from the seasonal influenza virus. The constancy of the HA epitope that reacts with MAb 5F7 provides its use for identification of the pandemic influenza strains in HI test. MAbs 3D9, 6A3 and 1E7 are directed against the variable HA epitopes, being sensitive to several amino acid changes in Sa, Sb, and Ca2 antigenic sites and in receptor binding site. These MAbs can be used to detect differences in HA structure and to study the antigenic drift of the pandemic influenza virus A(H1N1)pdm09.

Abstract
This study aimed to establish the influence of herpes simplex virus (HSV) on testis morphology and germ cell development using a model of ascending urogenital HSV infection in mice. Adult C57BL/6J mice were inoculated with 100 plaque-forming units of HSV1 in rete testis. Viral proteins and HSV DNA were detected from 3 days postinoculation (DPI), while capsids and virions could be visualized at 6 DPI. Infectious activity of HSV was revealed by rapid culture method in testes from 3 to 14 DPI, and virus DNA by PCR - from 3 to 100 DPI. Germ and Sertoli cells were infected during the early stages of the infection, whereas interstitial cells only occasionally contained the virus at 21 and 45 DPI. Microscopic analysis revealed severe degeneration of the germinal epithelium in the infected testes. By 21 DPI, testes became atrophic and most Sertoli cells were destroyed. No testicular regeneration and no spermatozoa in the epididymis were observed at 45 and 100 DPI. From 3 DPI, inflammatory cells accumulated in the interstitium between damaged tubules; a significant increase in the number of CD4(+), CD8(+) T lymphocytes and F4/80(+) cells was observed in the infected testes. This study shows that in the case of HSV retrograde ascent into seminiferous tubules, the acute viral infection results in irreversible atrophy of the germinal epithelium, orchitis and infertility. These results may be used to further study viral orchitis and the influence of HSV on spermatogenesis and male fertility.

Abstract
The goal of this work was to study the capacity of the herpes simplex virus (HSV) of infecting ovary with disease in case of the intravaginal experimental animals. The results of the study demonstrated that the ascending HSV infection in mice lead to modification of all the cells of the ovary, including follicular cells synthesizing estrogen and progesterone. The two hormones influence the development of the disease. Estrogens provide the protective effects against the virus. Progesterone does not modify the body sensitivity to HSV, but reduces the effectiveness of the antiviral immunity, resulting in increased mortality of animals. We demonstrated that infection of oocytes in ovarian follicles of female mice during infection with HSV modified the process in vitro and for the first time demonstrated the detection of viral antigens in mature oocytes in patient with infertility. During the intracytoplasmic sperm injection into the infected oocytes (ICSI), the failure of fertilization was observed. These results are of interest, because there is no available literature on whether HSV infection of oocytes can have a direct negative impact on the process of fertilization in humans.

Abstract
Herpes simplex virus (HSV) causes inflammatory diseases of the genitourinary system of males, infects male sex cells, and its presence in the ejaculate is associated with infertility. However, information on the pathways of HSV in the testicles, the extent of damage of spermatogenic tissue and the effect on spermatogenesis are insufficient. This work was aimed to the evaluation of effect of HSV on mice spermatogenesis in retrograde infection with the virus. Molecular (RT-PCR), virologic, morphological and immunohistochemical methods were used. Analysis showed that after virus inoculation directly into seminiferous tubules the viral protein is found in all layers of seminiferous epithelium. On the third day of infection the proportion of tubules containing HSV protein was 4.9%, reached a maximum on day 6 - 23,5 and 18% for the high and low doses of HSV, respectively, and then decreased; viral protein was not detected on 21th and 45th day. HSV DNA was detected in the testes at all stages of infection. Since the 14th day after infection, testes weight was significantly reduced compared to the control: 7,9-fold decrease at 45th day with a high dose of HSV, and 4,9-fold decrease with low dose. The infection with HSV led to the development of orchitis and considerable destructive changes in the spermatogenic tissue. The proportion of morphologically normal tubules was reduced to 6 and 15% at day 14 and remained at a low level up to 45th day. Approximately half of the seminiferous tubules (46.5%) at the 14th and 21th day had no somatic Sertoli cells needed for the restoration of spermatogenic tissue. These data suggests that retrograde infection of male gonads with HSV leads to the structure damage of testis and death of germ and somatic cells, indicating the irreversibility of degenerative changes in infected testes.

Abstract
A relationship between the herpesviral infections and male reproductive health is of importance to both theoretical and practical medicine. The review contains the data on the frequency of herpes virus identification in sperm, the effect of the viruses on structure and function of male germ cells, potential vertical transmission of the herpes viruses with male gametes, and experimental models of study the effects of herpes viruses on spermatogenesis. From the analysis of these data it can be concluded that: 1) identification of herpes virus in sperm is associated with reduced fertility; 2) herpes simplex virus has a negative effect on spermatogenesis, which manifests itself in a decreased proliferative activity of spermatogonia, meiosis block and enhanced apoptosis of germ cells; 3) herpes viruses can be found intracellularly in male gametes; and 4) the analysis of the markers of widespread herpes viruses (HSV, CMV) should be included in examination of men attending infertility clinics.

Abstract
A promising approach to construction of antiviral vaccines consists in activation of cellular immunity with the DNA vaccines. The goal of this work was to evaluate the efficacy of genetic immunization of mice with DNA pcNS3-NS5B encoding five hepatitis C virus (HCV) nonstructural proteins: NS3, NS4A, NS4B, NS5A, and NS5B in comparison with plasmids containing genes of same individual nonstructural proteins. The DNA constructions were injected intramuscularly in DBA mice three times. The humoral immune response was assessed with ELISA; cellular immune response--in blast transformation reaction, by quantitation of CD4+ and CD8+ T cell proliferation using flow cytofluorometry, by intracellular synthesis and secretion of IFN-gamma and IL-2 in ELISpot and ELISA. It was found that the functionally active T cell response was achieved to antigens presenting NS3, NS4, NS5A, and NS5B epitopes of different HCV genotypes in response to pcNS3-NS5B plasmid and was stronger than that to plasmids carrying individual genes. A high proliferation rate of CD4+ T cells, secretion of IL-2 and IFN-gamma, induction of anti-NS3 and anti-NS5B IgG2a were demonstrated. These findings indicate that DNA construction pcNS3-NS5B is one of promising candidates for anti-HCV vaccine developing.

Abstract
The goal of this work was to examine the effects of infections caused by HSV1/2, CMV, and HPV on the cytokine profile in pregnant women with obstetric complications (OC) and to evaluate the efficacy of the therapy with recombinant human alpha2b interferon. Direct markers of the viruses were identified using PCR and rapid culture method in 85 pregnant women divided into 3 groups: group 1 (n = 21), women with visual HPV-related clinical manifestations; group 2 (n = 48), with detectable markers of viral infections and no clinical manifestations, and group 3 consisting of pregnant women with OC without markers and clinical manifestations of viral infections (n = 16). The rate of HPV DNA detection in pregnant women was higher than that of herpesviruses (HV) CMV and/ or HSV: 37.6% vs. 11.8%. The frequency of mixed HV/HPV infection in group 1 was 2.3-fold higher than in group 2. The cytokine levels of IFNalpha, IFNgamma, IL-4, IL-6, IL-8, and TNFalpha in blood plasma and vaginal washings were studied. Statistically significant differences in infected women (groups 1 and 2) in comparison with uninfected women (group 3) were detected: a) blood plasma concentration of IFNgamma increased in clinically manifested HPV infection; b) blood plasma IL-8 concentration increased in clinically manifested HPV and in mixed HV+HPV infections without clinical symptoms of HPV infection; c) blood plasma concentration of TNFalpha increased in women with asymptomatic HPV-infection; d) IL-6 concentration in vaginal washings increased in mixed infection in group 1. The effect of IFN-alpha2b was assessed by analyzing cytokine levels in women on basic therapy with and without Viferon. In infected women, Viferon caused a 2-3-fold decrease in the concentrations of IFNgamma and IL-8 in blood plasma, thus bringing them near those of uninfected women with OC. The analysis of the state of newborns health has shown that for women with OC the risk of giving birth to a child in critical condition is 4.3-fold higher when CMV is detected in the third trimester of pregnancy.

Abstract
Hepatitis C is related to the most important socially significant human infectious diseases; however, vaccine against this virus up to now has notbeen created. One of the possible components of vaccine is the nonstructural protein NS3 of hepatitis C virus (HCV), which is synthesized in the infected cells and displays protease, NTPase, and helicase enzymatic activities. The connection between the effectiveness ofT cellular response to NS3 epitopes and the spontaneous resolution of acute hepatitis C was shown. The purpose of this work was to compare the immune response of mice to the inoculation of nucleotide and amino acid sequences of HCV NS3 and their combination, to evaluate the adjuvant activity of the DNA encoding granulocyte macrophage colony-stimulating factor (GM-CSF) and the influence of regulatory T cells on the effectiveness of immune response. The maximum anti-HCV NS3 antibody level in the serum (to 1:640000) induced the recombinant protein rNS3 introduced with aluminum hydroxide. The most intensive cellular immune response was observed after the simultaneous administration of rNS3 and DNAs encoding full-size NS3 and GM-CSF. A high level of lymphocyte proliferation, accumulation of IFN-gamma-secreting cells and IFN-gamma, and IL-2 release in response to the stimulators--NS3 antigens of different composition were observed in this group of mice. It has been established that the suppression of regulatory T cells in vitro leads to the statistically significant increase in the secretion of IFN-gamma. Thus, simultaneous application of rNS3 along with the DNAs encoding full-size NS3 and GM-CSF is promising approach for development of hepatitis C vaccine. The expediency of inclusion in the vaccine composition of regulatory T cell inhibitors will be clear after special studies.

Abstract
We have conducted a comparative analysis of developing human embryos in the course of in vitro fertilization (IVF) as a method of sterility treatment of two groups of patients: herpes simplex virus (HSV) was detected in the fraction of motile sperm of male partners in group I (n = 28) and no HSV was found in sperm in group II (n = 103). W assessed number of fertilized ova, embryos during cleavage, and blastocysts as well as such parameters as frequency of implantation and frequency of pregnancy in IVF cycles. It was established that the presence of HSV in spermatozoa did not affect the efficiency of fertilization or cleavage of zygotes. At the same time, in cases of virus-infected male gametes, the frequency ofblastocyst formation was two times less (p = 0.015), and the frequency of embryo implantation and pregnancy was, on average, five times lower (p = 0.01 andp = 0.016, respectively). Based on the obtained results, a conclusion was made about the negative influence of HSV-virus in male gametes at the early stages of embryo development and the frequency of achievement of pregnancy in respect to the methods of assisted reproductive technologies (ART).

Abstract
To investigate the effect of Herpes Simplex virus (HSV) on spermatogenesis, HSV in ejaculate was detected by a rapid cultural method in 268 infertile males and 47 healthy ones. The number of mobile spermatozoa in HSV infected samples was less than in non-infected samples (21 mln/mlversus 40 mln/ml, p = 0.0001). The relative number of morphologically normal gametes was 13% versus 19% (p = 0.002), respectively. The quantitative karyological test discovered that males with HSV-infected ejaculate have more degenerating sex cells while in high virus contamination (more than 10 virus particles in 1 ml) the number of spermatides and spermatocytes of the 1 order at diploten stage is low. Organic testicular culture was used for more detailed study of pathogenetic mechanisms of HSV impact on spermatogenesis. Testicular explants infection was associated with reduction in the number of spermatogones, spermatocytes and spermatides on culturing week 2. The above findings reveal some pathogenetic mechanisms underling fertility disorders in males with HSV infection: a gametotoxic effect of the virus reducing populations of spermatogones, spermatocytes and spermatide; affected mobility and morphological characteristics of spermatozoa. Detection of the mechanisms of HSV action on spermatogenesis opens a perspective of antivirus drug administration in combined treatment of male infertility.
