title: [Kinetics of cell population of the jejunal mucosal epithelium in mice after administration of syngeneic lymphocytes].
abstract: By means of the radioautographic method the state of cellular restoration of the gastric epithelium has been estimated after administration of syngenic lymphocytes to mice. Under conditions of physiological regeneration T-lymphocytes are able to inhibit proliferation of the epithelial cells and to limit the size of the proliferation zone in crypts. The inhibition degree of the proliferative activity depends on the doze of the T-cells administered. In order to demonstrate their activity, T-cells do not need DNA and RNA synthesis de novo. At the same time, protein synthesis is necessary; it occurs on long-living mRNA lymphocytes. The T-lymphocyte action is reversible at the tissue, but not at the cellular level. The mechanism of decreasing cell reproduction under effect of T-lymphocytes is described. In the process of lymphoid regulation of the cellular restoration in the intestinal epithelium changes in the size of the proliferative pool play the main role.
