Effect of estrogen on FasL expression in activated CD8+ T cells. Purified CD8+ T cells were isolated and stimulated with plate-bound CD3/CD28 in the presence and absence of estrogen (10-8M) for 24 h. The cells were stained with PE-labeled anti-FasL antibodies. Filled area, isotype control; green line, CD3/CD28-stimulated cells; pink line, CD3/CD28 and estrogen.

IFN-γ levels in activated CD8+ T cells. Purified CD8+ T cells were cultured in the presence and absence of plate-bound Fas-Fc/CD3/CD28 in the presence and absence of estrogen. IFN-γ was estimated using a commercial ELISA kit.
