title: Control of autologous immune complex nephritis. I. Suppression of the disease in the presence of T cell sensitization.
abstract: Pretreatment of Lewis and Sprague-Dawley rats with the nephritogenic antigen, Fx1A, in incomplete Freund's adjuvant (IFA) reduced the incidence of autologous immune complex nephritis in rats subsequently challenged with Fx1A in complete Freund's adjuvant (CFA). The suppression was evidenced by a decrease in antibody production, in glomerular deposition of immunoglobulins, and in the incidence of proteinuria, and it was antigen specific. In vitro blastogenesis to Fx1A of lymphocytes from Fx1A-IFA-pretreated animals was normal. Rats pretreated with Fx1A-IFA initially developed a normal antibody response after challenge with Fx1A-CFA, but the response was not sustained. These results indicate that the Fx1A-IFA-induced suppressor mechanism does not inhibit sensitization, but rather modifies specific antibody production.
