Abstract:

Autoimmune regulator (Aire)-deficient mice and humans have circulating autoantibodies against a multitude of organs and multiorgan autoinflammatory infiltrates. It is not known to what extent autoantibodies or their source, B lymphocytes, are required for disease onset or progression. We show in this research that B cells must be present for Aire-deficient mice to develop fulminant infiltrates. We found no evidence that autoantibodies were directly pathogenic; rather, B cells appeared to play a critical early role in T cell priming or expansion. A therapeutic reagent directed against B cells, Rituximab, induced remission of the autoimmune disease in Aire-deficient mice, raising the hope of applying it to human patients with autoimmune-polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED).
