We report here identification of novel mimicry epitopes for interphotoreceptor retinoid-binding protein (IRBP) 201–216, a candidate ocular antigen that causes experimental autoimmune uveoretinitis (EAU) in A/J mice. One mimicry epitope from Ehrlichia canis (EHC), designated EHC 44–59, induced cross-reactive T cells for IRBP 201–216 capable of producing T helper (Th)1 and Th17 cytokines, but fai...
