title: [Effect of estrogen on the blast transformation of lymphocytes and interleukin-2 production in lupus erythematosus].
abstract: The mitogenic response of peripheral lymphocytes was investigated in 12 patients with systemic lupus erythematosus and in healthy female volunteers who were on 11 and without 9 contraceptive pills. The effect of estrogen (ethinyl-estradiol 10(-5)-10(-6)-10(-7)M) was studied on Phytohaemagglutinin and Pokeweed mitogen induced blastogenic transformation and interleukin-2 production of peripheral lymphocytes in vitro. We observed a significantly depressed Phytohaemagglutinin induced lymphoblastic transformation both in patients and women taking oral contraceptive in presence of 10(-5)M estrogen as compared to normal controls. However there was no significant alteration neither in the response of lymphocyte nor in the production of interleukin-2 using of Pokeweed mitogen. The stimulataneous inhibition of the interleukin-2 production proved to be moderate. Marked significant correlation (r greater than = 0.8) vas detected between lymphoblastic transformation and interleukin-2 production in healthy females. Correlation coefficient measured in females taking oral contraceptive (r less than = 0.64) and patients with systemic lupus erythematosus (r less than = 0.34) suggest that in these groups the inhibition of lymphoblastic transformation is due to the inhibition effect of estrogen on the interleukin-2 production.
