GUT ASSOCIATED LYMPHOID TISSUE AS INFORMATION AND CORRECTIVE SYSTEM OF EXTREME CONDITIONS (brief literature report)
The presented experimental data in this review indicate an important role of lymphoid tissue in the conditions of influence on the organism of various extreme factors. It can be argued that all related restructuring occurred at the level of interaction of lymphocytes with target tissue. They are related to the nature of intracellular changes in lymphocytes, defining the way to manage change pathogenesis of diseases. Multifunctionality of small intestine determines its participation in many processes involving immune responses, inducing recovery. Taking into account the migratory ability of lymphoid cells, their ability to obtain information and interaction with other bodies are expanded. They are able to provide a quick change of the normal development of the body's program to back and vice versa. Topographic feature lymphoid component in the intestinal wall as one of the protective barriers in the way of antigens, allows to evaluating the influencing factors effects. It was noted the importance of Paneth cells in some studies, as well as their own plasmacytoid infiltration of the mucous membrane layer defining the character of the small intestine resistant response. Thus, the lymphoid cells are operational subsystem, the biological essence of which lies in the variability of tissue and its adaptation to the environment.
