CELLULAR COMPOSITION AND MITOTIC ACTIVITY OF LYMPHOCYTES IN THE LYMPH NODES OF PEYER'S PATCHES OF THE SMALL INTESTINE
Keywords:
lymphoid follicle, Peyer's cell, mitotic activity of lymphocytes, interepithelial lymphocytes.Abstract
The small intestine is constantly in contact with natural antigens, first of all with highly immunogenic microorganisms, and undergoes drastic structural and functional reconstructions. They are manifested by changes in the linear parameters of villi and crypts, acceleration of enterocyte renewal, increased infiltration of interepithelial lymphocytes, enrichment of the private plate with immunocompetent cells, clear separation of structural and functional zones of Peyer's cells.
