Circulating autoantibodies specific for retinal proteins are associated with retinal destruction in patients with diabetic retinopathy (DR). In this study, we screened diabetic sera for the presence of anti-retinal autoantibodies with an aim of developing diagnostic markers for DR. Immunoblot analysis of DR patients' sera with human retinal cytosolic proteins revealed a higher incidence of anti-retinal autoantibodies, compared to normal blood donors or diabetic patients without DR. Anti-retinal protein autoantibody profiles of DR patient sera were obtained by 2-DE immunoblot analysis. Specifically, 20 protein spots reactive with DR patient sera were identified by ESI-MS/MS. Of these spots, 14 were specific for DR patients, and 4 reacted with both non-proliferative DR (non-PDR) and PDR sera. The anti-aldolase autoantibody was selected as a DR marker candidate, and specific reactivity of DR patient sera was confirmed by immunoblot analysis with rabbit aldolase. The serum anti-aldolase autoantibody level was measured by ELISA. DR patients showed significantly higher autoantibody levels than normal donors or diabetic patients without retinopathy. However, no significant differences were observed between non-PDR and PDR patients, suggesting that the level of anti-aldolase autoantibody is not determined by the severity of retinopathy in diabetic patients. Our data collectively demonstrate that the anti-aldolase autoantibody serves as a useful marker for DR diagnosis.

We conducted an allozyme electrophoretic study to explore potential enzyme markers to distinguish Opisthorchis viverrini in Thailand and Lao PDR. Twenty-eight enzymes encoding presumptive 32 loci were established. The enzymes glucose-6-phosphate dehydrogenase and pyruvate kinase were diagnostic between two geographically separate isolates from Thailand. Twelve enzymes, ie, aconitate hydratase, aldolase, creatine kinase, enolase, esterases, fumarate hydratase, aspartate aminotransferase, glucose-phosphate isomerase, alanine aminotransferase, isocitrate dehydrogenase, malic enzyme, and pyruvate kinase, also provided diagnostic markers for these two isolates from Thailand and one isolate from Lao PDR.
