Family Analysis of Linkage and Association of HLA-DRB1, CTLA4, TGFB1, IL4, CCR5, RANTES, MMP9 and TIMP1 Gene Polymorphisms with Multiple Sclerosis.

Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease of the central nervous system (CNS). Proteins of the immune system, as well as proteins that are involved in the infiltration of activated immune cells in the CNS, play an important role in the pathogenesis of MS. We investigated the association and linkage with MS of the following immune-system genes polymorphisms: HLA-DRB1,CTLA4,TGFB1,IL4,CCR5 andRANTES, as well as of the matrix metalloproteinase 9 (MMP9) and tissue inhibitor of metalloproteinase  1 (TIMP1) genes polymorphisms.

[Analysis of linkage and association of alleles of proinflammatory cytokines genes IL-6, IFNg and TNF with multiple sclerosis using transmission disequilibrium test (TDT)].

Proinflammatory cytokines Interleukin-6 (IL-6), Interferon-gamma (IFNg) and Tumor necrosis factor (TNF) are known as participants of inflammation and play an important role in pathogenesis of multiple sclerosis (MS). Based on literature data about influence of SNPs G(-308)A of TNF gene, A(+874)T of IFNG gene and G(-174)C of IL-6 gene on production of these cytokines, we investigated association of these polymorphic sites with MS. Linkage and association of alleles of these genes with MS was analyzed by transmission disequilibrium test (TDT).

[The heterogeneity of the ospa gene of Borrelia garinii and Borrelia afzelii in western Siberia and Mongolia].

48 full-length Borrelia garinii and Borrelia afzelii from West Siberia and Mongolia ospA gene nucleotide sequences was determined. Four groups of Borrelia garinii were revealed using the analysis of nucleotide sequences. The most variable ospA gene region was demonstrated to be included in region where the antigenic determinants of protein were encoded.

[Symptomatic therapy of bladder hyporeflexia in patients with multiple sclerosis].

Symptomatic therapy of bladder hyporeflexia in patients with multiple sclerosis by intermittent catheterization in cases of insufficient efficacy of alpha-adrenoblockers allows to prevent bacterial infection complications and chronic renal failure and to achieve significant improvement of quality of life of such patients.
