title: Occurrence of autoimmune antibodies to liver microsomal proteins in association with fulminant hepatitis in the LEC strain of rats.
abstract: The Long Evans Cinnamon (LEC) rat, which has been established as a strain showing hereditary hepatitis and hepatic carcinoma, was found to possess autoimmune antibodies to liver microsomal proteins, particularly to a protein with the molecular weight of 56kD. The antibodies also recognized a protein(s) in liver microsomes from Long Evans Agouti and Sprague-Dawley rats. About 42 and 15 percent of respective female and male LEC rats died within a week after acute hepatitis; sera from all of the animals contained the antibodies. About 43 and 0 percent of the surviving female and male LEC rats possessed the antibodies, respectively. These results suggest that the autoantibodies occur in association with acute lethal hepatitis in the LEC rats.
