Impact of bacterial lectin on functional activity of lymphocytes

Institute of Biochemistry and Physiology of Plants and Microorganisms, State Medical University, Saratov, Russia

Impact of Azospirillum brasilense Sp7 lectin with carbohydrate specificity to L-fucose on T- and B-lymphocytes production, activity of IL-1α, and TNF-α 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-1α and TNF-α. It has been shown that the bacterial lectin has more pronounced stimulatory effect on functional activity of lymphocytes compared with PHA.
