[Impact of bacterial lectin on functional activity of lymphocytes].

Impact of Azospirillum brasilense Sp7 lectin with carbohydrate specificity to L-fucose on T- and B-lymphocytes production, activity of IL-1alpha, and TNF-alpha was studied in vitro and compared with influence of red kidney bean phytohemagglutinin (PHA) on the same parameters. Increase of growth of T- and B-cells subpopulations has been shown that point to stimulatory effect of the bacterial lectin. Bacterial lectin of A. brasilense also increased synthesis of IL-1alpha and TNF-alpha. It has been shown that the bacterial lectin has more pronounced stimulatory effect on functional activity of lymphocytes compared with PHA.
