Notes:
Effect or anti-lymphocyte antibody or active systemic lupus erythematosus (SLE) on lymphocyte function was examined. Lymphocytes from normal individuals treated with anti-lymphocyte antibody and complement exhibited marked inhibition of response to concanavalin A (Con A). while the response of lymphocytes to phytohaemagglutinin M (PHA-M) and pokeweed mitogen (PWM) was slightly affected. In mixed lymphocyte culture response, both stimulator and responder tells were insensitive to anti-lymphocyte antibody. Treatment of sensitized lymphocytes with anti-lymphocyte amibody and complement caused a dose-dependent suppression of blaslo-genic response to purified protein derivatives (PPD). No effect, however, was noted on migration-inhibitory factor (MlF)-producing cells. In PWM-driven Ig synthesis, T lymphocytes lacking the anti-lymphocyte antibody-reactive T-cell subset enhanced PWM-driven Ig synthesis of autologous B lymphocytes. Con-A-induced suppressor function of lymphocytes was abolished by the treatment with unti-lymphocytc antibody and complement. The present study demonstrated that lymphocytes from normal individuals after treatment with anti-lymphocyte antibody and complement showed similar immunological reactivities with lymphocytes from active SLE, indicating that those anti-lymphocyte antibodies could play an important role in defective suppressor cell function.
