IL-17 Autocrine Loop (IMAGE) NIH/National Eye Institute Caption After activation through its T-cell receptor, Th17 cells produce IL-17A, which binds to its own receptor on the Th17 cell. This activates the NFκB pathway. NFκB drives production of IL-24, which in turn suppresses the Th17 cytokine program via SOCS1 and 3.
