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
INTRODUCTION The mouse-specific orthopoxvirus, ectromelia virus, is one of the best models that can be used to study key issues of pathogenesis, prevention, and treatment of smallpox, and to develop measures to increase virulence, transmissibility, or the ability to overcome vaccine immunity. The aim of the work is to screen the antiviral activity of samples from Inonotus obliquus chaga and humic acid from brown coal in vitro against ectromelia virus. MATERIALS AND METHODS We used ectromelia virus, strain K-1 (reg. No V-142), obtained from the State Collection of Pathogens of Viral Infections and Rickettsioses of the State Scientific Center of Virology and Biotechnology "Vector"; Vero Е6 cell culture (No 70) from the Collection of cell cultures of the State Scientific Center of Virology and Biotechnology "Vector". Nine samples from chaga I. obliquus and humic acid from brown coal were used to evaluate the changes in the infectivity of the ectromelia virus on cell culture using 2 schemes of application of drugs and virus (preventive and therapeutic schemes), and to assess their cytotoxicity and antiviral activity. RESULTS 50% cytotoxic concentration, 50% virus-inhibiting concentrations and selectivity index were determined for all samples. The studied samples were shown to be non-toxic to the monolayer of Vero cell culture in a dilution of 300 and more micrograms/ml, while demonstrated high antiviral activity against strain K-1 of ectromelia virus in two application schemes - preventive and curative. CONCLUSION All samples tested for ectromelia virus in vitro can be considered promising for further development of drugs against diseases caused by orthopoxviruses.

Abstract
We propose a model of rheumatoid arthritis (RA) induced in outbred guinea pigs using a single subcutaneous injection of complete Freunds adjuvant to the hind paw. Histological examination of this model shows fibrin deposition on the surface of the synovial membrane, leukocyte infiltration of the synovial membrane and adjacent tissues, proliferation of the granulation tissue, and emergence of angioid areas, characteristic of RA. The cell response appears as an increase in the plasma cell count and development of follicle-like lymphoid infiltrates; erosion of the articular surface of the cartilage, frequently with deep cartilage destruction over large areas; and epiphysiopathy. The high reproducibility of arthritis induction in this RA model has been demonstrated. The proposed model is promising for the assessment of anti-arthritis preparations and dosage regimens.

Abstract
Gene therapy can offer a new approach to arthritis treatment which acts at an inflammation site. Numerous studies show high efficacy of gene therapy in different models of arthritis in humans. Even a single injection of a recombinant vector results in a stable prolonged expression of a therapeutic gene and a longterm therapeutic effect. In contrast to biologic therapy involving numerous systemic injections of recombinant anti-inflammatory proteins, gene therapy does not produce systemic side effects. Vectors based on retroviruses, adenoviruses, adeno-associated viruses, and recombinant plasmids could provide delivery of target genes. Of significant importance is the development of noninvasive methods of gene therapy: intranasal and peroral. The current state of research in arthritis gene therapy is discussed in this review.

Abstract
Gel-filtration chromatographic separation of the lysate of Sf21 insect cells infected with recombinant baculovirus BVi67 containing the gene for TNF-binding protein (CrmB) of variola virus (VARV) revealed that hTNF-cytotoxicity neutralization activity is associated with a fraction corresponding mainly to high molecular weight proteins (above 500 kDa) and less with fractions corresponding to proteins of 270 or 90 kDa. The recombinant VARV-CrmB protein has been purified by affinity chromatography. Difference in the experimentally determined and estimated (according to amino acid composition) VARV-CrmB molecular weight is due to glycosylation of the recombinant protein expressed in the insect cells. VARV-CrmB neutralizes in vitro the cytotoxic effect of hTNF and hLTalpha, and its TNF-neutralizing activity is two to three orders of magnitude higher compared to the analogous effects of type I and II soluble TNF receptors, comparable with the activity of mAb MAK195, and somewhat lower than the effect of the commercial drug Remicade.
