The role apoptosis in dysregulations of lokal and system immunitet at the Helicobacter pilory-infection

Abstract

The level of intracellular apoptosis regulators (cell death antagonists (Bcl-2) and agonists (CPP-32)), proliferation antigen Ki67 in lymphocytes of biopsy materials of the mucous coat of stomach at Helicobacter pylori-associated gastric ulcer and chronic gastritis in Khakassian aboriginal population and newcomers have been studied. The lymphocyte apoptosis in peripheral blood in aboriginal population was assessed. Changes in immunological indices were revealed in patients infected with Helicobacter pylori compared to healthy donors and newcomers. These changes were characterized by the more intense apoptotic lymphocyte death compared to the number of such cells in patients with chronic gastritis and in the control group. The role of apoptosis disfunctions in the regulation of local and system immunity at Helicobacter pylori infection is discussed.
