[Antigen-specific helper and suppressor activities of T-lymphocytes of the rabbit blood during the development of immunologic response to heterologous erythrocytes].

A titre of hemolysins in blood serum, helper and suppressor activity of blood T-lymphocytes in response of ++blast transformation to Con A in different doses (8 and 60 ml) and was determined in rabbits after single and two-fold (with an interval of 30 days) immunization of the ram erythrocytes. Examinations were conducted 2, 9, 16 and 30 days after antigen introduction. Peculiarities of changes in antigen-specific helper and suppressor activity of lymphocytes and their balance in dynamics of primary and secondary immune responses are determined.
