Objective To investigate the cellular phenotype involved in experimental autoimmune uveoretinitis (EAU) and apoptosis of infiltrating cells in this inflammation． Methods Immunohistochemical staining and in situ apoptosis staining were performed using monoclonal antibodies to monocytes and macrophages (EDI),MHC calss -II antigen (OX6),T lymphocytes (R73) and TACS 1 Klenow kit on both ocular sections and wholemounts of 16 Lewis rats after immunization with interphotoreceptor retinod-binding protein(IRBP). Results EAU was induced in 12 of 16 Lewis rats with a clinical inflammation score being 1.29 plusmn;0 .7.Influx of monocytes,lymphocytes and MHC class II+ cells into the uvea and retina was noted after immunization with IRBP.Apoptosis of infiltrating cells was observed in the uvea and retina and more apoptotic cells were present in the iris and ciliary body compared with the choroid and retina. Conclusion A number of cells including monocytes,macrophages,lymphocytes and MHC class II+ cells are involved in EAU induced by IRBP.Apoptosis of infiltrating cells occurs at early stage of EAU,which may greatly contribute to the rapid regression of the inflammation induced by IRBP.
