[Ca(2+)-dependent regulation of T-lymphocytes in experimental tuberculosis]

Ca(2+)-exchange kinetics and the content of membrane and cytoplasm fractions of calmodulin in the splenic T-lymphocytes of guinea pigs with experimental tuberculosis were studied. A tuberculous process was accompanied by the changes in the Ca2+ exchange kinetics in the form of T-lymphocyte oversaturation with Ca2+ ions which in the end leads to an inhibition of the functional status of the immunity T system. PPD, a specific allergen, brought the capacity of T lymphocytes down in relation to the cellular Ca2+ exchange, presumably causing the normalization of the immune response.
