title: Mink with Aleutian disease have autoantibodies to some autoantigens.
abstract: Thirty mink infected with Aleutian disease virus (ADV) were found to have elevated levels of antibody to double-stranded DNA (dsDNA) in their sera when compared to 30 healthy mink. The anti-dsDNA antibody levels in the diseased mink were, however, not found to correlate with the total amount of immunoglobulin. This was a common observation for all autoantibodies tested. The concentration of rheumatoid factors of IgG class, but not those of IgM class, was found to be significantly higher in the diseased mink at the chosen level of significance (P less than 0.01). IgG antibodies to thyroglobulin were likewise significantly higher in the ADV-infected mink. Unexpectedly, we found IgG antibodies with specificities for cardiolipin and mitochondrial antigens to be significantly higher in healthy mink than in ADV-infected mink. This difference is especially remarkable since the serum immunoglobulin concentration of the ADV-infected mink was three times higher than the serum immunoglobulin concentration of the normal mink.
