| Outline of Final Research Achievements |
The purpose of this study is to investigate the clinical and immunological characterization of autoimmune retinopathy (AIR) and to determine the retinal autoantigens recognized by sera of AIR patients. Serum samples obtained from 105 AIR patients were analyzed by Western blot and immunohistochemistry. We reported that AIR was associated with a variety of autoantibodies and the OCT and IHC findings showed some correlation. The 13 cDNA clones of retinal autoantigens were isolated from human retinal cDNA library by PCR and inserted into expression vector of E. coli. The recombinant proteins of retinal antigens were purified by affinity chromatography. The sera of AIR patients were examined reactivity against the recombinant proteins by WB analysis. We found that 6 retinal autoantigens were recognized with more than 7 sera from AIR patients. The retinal antigens may be a potential biomarker for diagnosis of AIR. Further investigations of the pathology associated with AIR are needed.
