THE THYMUS GLAND IS THE CENTRAL ORGAN OF IMMUNITY AND BLOOD CIRCULATION

Abstract

In the last 20-25 years, there has been a very rapid development of immunology, the
cellular and subcellular foundations of the immune response, the participation of the thymus in
immunosuppression processes have been clarified. The thymus is the central organ of the immune
system, where, under the action of hormones and biologically active substances, the number of
which includes more than 30 names, the initial stages of T-lymphopoiesis are carried out, the
formed pretimocytes and thymocytes migrate from the thymus to the peripheral organs of
immunity and reach their maturity. At the same time, the structural and functional features of the
thymus reaction during antigenic stimulation are still poorly understood. In this regard, the purpose
of our study was to clarify the cellular and subcellular mechanisms of thymus involvement in
immunogenesis in experimental salmonella infection.
