The immune response to viral antigens as a determinant of arthritis in caprine arthritis-encephalitis virus infection.
Evidence is reviewed which indicates that CAEV persists in infected goats with variable and restricted expression. Immunosuppression prevents the lesions caused by CAEV. Arthritis is enhanced in CAEV-challenged goats that have been immunized with inactivated CAEV or are persistently infected with CAEV. A large part of the synovial fluid immunoglobulin is antibody against virion surface glycoproteins. These observations support the hypothesis that the immune response to viral antigens is a major determinant of CAEV arthritis.
