PURPOSE: This study was carried out in order to determine the most potent and novel uveitopathogenic sites of recoverin using synthetic peptides.
METHODS: Several synthetic peptides containing the recoverin sequence plus adjuvants were injected into Lewis rats, and the uveitopathogenic sequence was defined, clinically, histologically, and immunologically.
RESULTS: Peptides containing of amino acids 57-85 and 136-167 induced severe EAU, and the lowest doses to induce EAU were 20 microg and 10 microg, respectively. Lymphocyte proliferative reactions were also positive for peptides 57-85 and 136-167. The core sequences within the uveitopathogenic site were 65-79 and 153-164. Peptides of amino acids 65-79 within 57-85 and 149-167 within 136-167 were the smallest in the recoverin sequence, respectively, that could induce severe EAU.
CONCLUSION: We found recoverin has some novel potent uveitopathogenic sites, 149-167. These findings of the uveitopathogenic sites in recoverin may lead to improved understanding of the pathogenesis of uveitis and the means to design specific treatment.
