Both, IFN-γ- and IL-17-producing populations, which did not coexpress the respective other cytokine, remained quite stable during the course of monophasic EAU (PDSAg), while during the course of relapsing uveitis (R14) IL-17+/IFN-γ− cells decreased and IFN-γ+/IL-17− cells increased. The gene discussed is IFNG; the disease is uveitis.
