Abstract

Previous studies have shown that treatment of rodents with a lymphotoxin (LT)-β receptor-Ig fusion protein (LTβR-Ig), which binds to both LT and LIGHT, prevents the development of autoimmune diseases, but the mechanism involved is unclear. To explore the potential role of LT or LIGHT in the pathogenesis of autoimmune uveitis, uveitis was induced in Lewis rats either by immunization with an uveitogenic peptide, R16, derived from the interphotoreceptor retinoid-binding protein, or by adoptive transfer of R16-specific T cells. Interestingly, LTβR-Ig treatment completely prevented actively induced uveitis, but not the adoptively transferred disease. We also show that LTβR-Ig-treated R16-injected rats had a significantly decreased T cell response to R16 and that herpesvirus entry mediator (HVEM)-Ig, a fusion protein that blocks LIGHT, also inhibited disease development. Our results suggest that LT or LIGHT plays a critical role in the induction, rather than the effector, phase of the disease.
