II. Effect of anti-lymphocyte antibody on autoreactive cell clones. PG - 479-88 AB - The effect of anti-lymphocyte antibodies of active systemic lupus erythematosus (SLE) on the immune regulation of autoantibody production was studied. The present study demonstrated that there were native DNA (nDNA)-sensitized T lymphocytes even in inactive SLE and no or few nDNA-sensitized T lymphocytes in normal individuals, and that in the inactive stages of SLE suppressor T lymphocytes might inhibit the activation of nDNA-sensitized T lymphocytes eliciting the production of anti-DNA antibodies by B lymphocytes. In the active stage of SLE, the anti-lymphocyte antibodies could eliminate the suppressor function of T lymphocytes or a subset of cells capable of either regulating their appearance or differentiating into them, which inhibited such responses. The different suppression of DNA and extractable nuclear antigen (ENA)-stimulated blastogenic response is further discussed.
