title: Induction of experimental autoimmune uveoretinitis and pinealitis by IRBP. Comparison to uveoretinitis induced by S-antigen and opsin.
abstract: Microgram quantities bovine IRBP (interphotoreceptor retinoid binding protein) injected in Freund's complete adjuvant induced severe autoimmune uveoretinitis and pinealitis in Lewis rats. At low doses the onset was accelerated and intensified by co-injection of Hemophilus pertussis bacteria. Wistar, BN and PVG rats were less susceptible, while the eyes of athymic, nude rats did not respond. The disease developed similar to but faster than S-antigen-induced uveoretinitis, while its onset was one day earlier and the reactions were slightly more severe. As distinct from these two types of uveoretinitis, opsin (in much higher doses) caused milder reactions in the anterior segment, while retinitis dominated. In each type of inflammation the photoreceptor cell layer was totally destroyed. All three ocular diseases were inhibited by cyclosporine treatment, which indicates that T cell-dependent mechanisms are essential for the development.
