Systemic lupus erythematosus (SLE) is an autoimmune disease of complex etiology in which B cells play a central role. An expanded number of B-1a cells have been consistently associated with murine lupus, and more recently with human SLE. We have identified Cdkn2c, a gene that controls cell cycle progression, as a key regulator of B-1a cell numbers and have associated Cdkn2c deficiency with autoimmune pathology, including the production of autoantibodies and the skewing of CD4+ T cells toward inflammatory effector functions. We review the genetic studies that have led to these findings, as well as the possible mechanisms by which B-1a cell expansion and Cdkn2c deficiency are related to SLE pathogenesis.
