Figure 2: Production of effector cytokines and CCR5 expression by Th17 and Th22 cells from blood and intestinal tissues of macaques. Dot plots showing TNF-α, IL-2, IFN-γ, Granzyme B and CCR5 expression of IL-17+ (A) or IL-22+ CD4 T cells (B) from blood and jejunum in uninfected macaques; (C) statistical comparison of cytokine-producing capability of Th17 and Th22 cells in peripheral blood and jejunum. * p<0.05, compared with peripheral blood-derived cells.
