INFLUENCE OF HERPES SIMPLEX VIRUS PERSISTENCE UPON PRODUCTION OF CYTOKINES BY IMMUNOCOMPETENT CELLS IN RHEUMATOID ARTHRITIS

Abstract. Using modern immunological methods of studies, we investigated some immunopathogenetic aspects of rheumatoid arthritis complicated by chronic herpesvirus infection. It was established that both rheumatoid arthritis, and chronic herpesvirus infection are accompanied by pronounced imbalance in production of immunoregulatory Th1/Th2-cytokines produced in immunocompetent cells of peripheral blood. In case of rheumatoid arthritis combined with herpes simplex infection, IL-2 and IFNγγ levels were decreased, whereas IL-4 и IL-6 levels proved to be increased, as compared with isolated diseases under study

ANALYSIS OF POLYMORPHIC VARIANTS OF CYTOKINE GENES IN PATIENTS WITH HIV INFECTION

Abstract. A distribution mode for allelic variants of cytokine genes was evaluated in 184 patients with slow viral infections, including 97 patients with chronic herpetic infection and 87 HIV-infected patients. Using modern methods of immunogenetics, we have found that relative risks of recurrent course and poor outcome of infection are positively associated with AA promoter region genotype and AA promoter genotype of +874 A/T polymorphism in the IFNG gene. Immunogenetic factors associated with protective effect in slow virus infections, include G allele of TNFA gene (G-308A SNP), and T allele/TT genotype of promoter region in  the IFNG gene (+874 A/T SNP).

ALLELIC POLYMORPHISM OF IFNγ GENE IN PATIENTS WITH PULMONARY TUBERCULOSIS

In present work, some immunogenetic aspects of pulmonary tuberculosis were studied, using modern techniques from molecular genetics and immunology. It is shown that carriage of Т allele and homozygous TT genotype in +874А/Т IFNγ gene polymorphism comprise a immunogenetic factor which correlated with a protective effect, regarding a susceptibility to pulmonary tuberculosis. Predisposition for tuberculosis infection is associated with A allele of this gene, as well as with АА and АТ genotypes of +874A/T IFNγ gene. Clinical evolution of pulmonary tuberculosis is accompanied by increase in IFNγ production
