TH1, TH2, TH17, and T follicular helper (TFH) cells represent four different subsets of CD4 effector cells. Each of these subsets produces a distinct set of cytokines when stimulated, that in turn, act to mobilize distinct immune effector mechanisms. While TH1, TH2, and TH17 cells recruit and activate innate immune cells, TFH cells act to amplify the adaptive immune response.
