[Phenotypic characteristics of the population of normal killers of autologous erythrocytes].

The presence of antigenic markers of T-lymphocytes (Thy-1, HKO-10, HKO-11 antigens) in phenotype of normal killers of autologous erythrocytes (NKAE) has been shown. Heterogeneity of NKAE in respect to sensitivity to PHA activating the cytotoxic activity of NKAE of mouse thymus and NKAE of people peripheral blood, but not NKAE of mouse bone marrow has been registered. A part of lymphocytes of T-row is supposed to possess the NKAE-function and to be responsible for homeostasis of red sprout of normal hemopoiesis.
