IL-17A protein expression is increased in Th0 and Th17 cells from women compared to men. (A–B) Naive CD4+ T cells were differentiated into Th0 and Th17 cells. IL-17A and IL-17F protein expression was determined in Th0 and Th17 from healthy women (n=13) or men (n=14). * p<0.05, Kruskal-Wallis test with Dunn's post-test analysis. (C) Total number of CD3+ CD4+ Th17 cells. (D–F) Percent, total number, and/or gMFI for CD3 gated, CD4+, IL-17A+ Th17 cells. * p<0.05, Kruskal-Wallis test, n=10 (women) n=12 (men).
