THYM GLAND - CENTRAL ORGAN OF IMMUNITY AND HEMATOPOIESIS

Abstract

In the last 20-25 years, there has been a very rapid development of immunology, the cellular and subcellular bases of the immune response, the participation of the thymus in immunoprotective processes have been elucidated [1,2,3,4,7,8]. The thymus is the central organ of the immune system, where under the influence of hormones and biologically active substances, the number of which includes more than 30 items, the initial stages of T-lymphopoiesis are carried out. The resulting prethymocytes and thymocytes migrate from the thymus to the peripheral organs of the immune system and reach their maturity [5,6 ,9,10]. At the same time, the structural and functional features of the thymus reaction during antigenic stimulation still remain poorly understood [2,4,11,12].
