Modulation of the Fashi thymocyte proportion by cytokines. Fas expression in human thymocytes was measured after 24 hours of incubation with IL-2 (200 U/mL), IL-6 (5 pg/mL), IL-7 (10 pg/mL) IL-12 (1 pg/mL), IFN-γ (500 U/mL), or the combination of IL-7 (10 pg/mL) + IFN-γ (500 U/mL). By contrast with the other cytokines, IFN-γ and the combination of IFN-γ + IL-7 significantly increased the Fashi thymocyte proportion. *P < .05 versus control.
