To investigate the regulation of anti-DNA antibody production, we generated anti-DNA-specific suppressor cells by exposing normal human T cells and a small percentage of adherent cells to high concentrations of DNA. These cells suppressed the production of anti-DNA by both autologous peripheral blood mononuclear cells (PBMC) and allogeneic PBMC derived from systemic lupus erythematosus (SLE) patients. Anti-DNA production was suppressed significantly more than anti-RNA, antitetanus, or total immunoglobulin production. Specific suppression was enhanced by increasing the numbers of DNA-primed CD8+ cells and was obliterated by irradiation of the DNA-primed cells. In contrast to T cells from normal individuals, T cells obtained from two intensively studied SLE patients were unable to generate specific suppressor cells for anti-DNA production in both autologous and allogeneic test systems. Despite this defect, these patients were still capable of generating specific suppressor cells for antibody production directed against an exogenous antigen, tetanus toxoid.
