Conversion of Monophasic to Recurrent Autoimmune Disease by Autoreactive T Cell Subsets¹

Department of Ophthalmology and Visual Sciences, Kentucky Lions Eye Center, University of Louisville, Louisville, KY 40202

Autoimmune uveitis has been elicited in susceptible rodents by several ocular-specific Ags. In most of these animal models the induced uveitis is acute and monophasic. Because recurrent uveitis poses the highest risk for blinding ocular complications in human disease, a spontaneous relapsing animal model would be most helpful in understanding the disease pathogenesis. In our current study we have observed that the adoptive transfer of interphotoreceptor retinoid-binding protein residues 1177–1191-specific T cells to naive Lewis rats induced a chronic relapsing disease, in contrast to the monophasic disease induced by immunization with interphotoreceptor retinoid-binding protein residues 1177–1191 emulsified in CFA. The chronic relapsing uveitis induced by autoreactive T cell subsets is dependent on the number of autoreactive T cells generated as well as their activation status. Our study documented a spontaneous model of recurrent uveitis in the rat, which should assist us in the study of disease pathogenesis and the design of specific therapy.
