IRF4 and uveitis: We induced experimental autoimmune uveitis (EAU) in WT C57BL/6J mice (control) and CD4-IRF4KO mice by immunization with the immunopathogenic uveitogenic peptide, IRBP651-670 in CFA emulsion and investigated whether targeted deletion of irf4 in CD4+ T cells would affect the development or severity of uveitis.
