Characterization of brain-reactive autoantibodies in murine models of systemic lupus erythematosus.
Using the Western blot technique we analyzed the sera of five strains of mice that develop a disease like systemic lupus erythematosus (SLE), along with two normal strains, for their binding specificities against isolated mouse integral brain membrane proteins. This report describes the distribution and frequency of the more than 200 brain-reactive autoantibodies in the 126 animals tested and verifies the hypothesis of diversity in anti-brain antibodies produced during autoimmune conditions such as SLE. These results emphasize the importance of characterizing the brain-reactive autoantibodies in the sera or cerebrospinal fluid of SLE patients with central nervous system involvement.
