Abstract

Many studies have described the presence of circulating antibodies against corneal components in patients with corneal disease or uveitis, and in patients with skin or systemic disease with or without ocular involvement. The role of such antibodies in the underlying immunopathological process remains obscure. Here we describe the induction of autoantibodies against the rat cornea. Our attempts to induce corneal autoantibodies by various forms of keratitis and corneal trauma failed. However, circulating corneal autoantibodies could be detected by Western blotting after immunization of BN rats and Lewis rats with bovine corneal protein 54 (BCP 54). Rats immunized with rat corneal extracts (RaCE) or human serum albumin (HSA) as (auto) antigen did not develop corneal autoantibodies. During the study period (greater than 4 months), it was observed that the presence of circulating corneal autoantibodies did not elicit corneal inflammation. Severe keratitis did develop when BCP 54-immunized rats were challenged intracorneally with BCP 54, but the clinical signs were not significantly different from HSA-immunized rats after an intracorneal HSA challenge. Injection of corneal autoantibodies into the corneal stroma did not provoke keratitis. To the best of our knowledge this is the first study demonstrating corneal autoantibodies in rats without actual manipulation of the eye. This model may provide further insights in the role and significance of corneal autoantibodies in disease.
