IL17A and parasitic infectious disease: Similar significant correlations were also observed between parasitemia and absolute numbers of Treg expressing GITR (Rs = 0.66, P = 0.0017), CTLA-4 (Rs = 0.47, P = 0.0349), IFN-γ (Rs = 0.52, P = 0.0187), TGF-β (Rs = 0.66, P = 0.0016), IL-10 (Rs = 0.59, P = 0.0067) and IL-17 (Rs = 0.68, P = 0.0011) (Figure 5).
