Genetic control of the immune response to poly(Glu52Lys33Tyr15) in neonatally thymectomized high and low responder rats. 1976

B K Davis, and J W Shonnard, and T J Gill

The immune response to poly (Glu52Lys33Tyr15) is under polygenic control and linked to the major histocompatibility complex of the rat. Aggregation of this antigen with methylated bovine serum albumin (MeBSA) eliminates the expression of genetic control by increasing the response of low responders and decreasing that of high responders. Humoral and cellular aspects of the immune response to both unaggregated and aggregated poly (Glu52Lys33Tyr15) were investigated in neonatally thymectomized high-responder ACI and low-responder F344 rats. T cells are necessary for responses to unaggregated poly (Glu52Lys33Tyr15) since thymectomy significantly decreased numbers of antibody-forming cells and serum antibody levels, and delayed hypersensitivity responses and antigen-induced in vitro proliferation. However, thymectomy had no significant effect on these parameters of immune responsiveness in either ACI or F344 rats immunized with poly (Glu52Lys33Tyr15)/MeBSA. Aggregation also increased IgG production and delayed hypersensitivity and antibody affinity in low responders.
