rIL-17s inhibit FICD and increase expression of cFLIP_S. FICD was performed in T cells from the healthy controls in the presence or absence of each recombinant cytokine. The results are expressed as % cell survival (A). The mean ± SE from 7 experiments are presented, *P < .05 (Wilcoxon’s signed rank test). (B) Western blot analysis of FLIP expression in cells harvested from the FIDC assay (representative of 4 experiments).
