Abstract/OtherAbstract:
Systemic lupus erythematosus is characterized by polyclonal B cell activation, the production of autoantibodies, and often by renal disease. Previous studies demonstrated that unfractionated B cells from several strains of mice with lupus hyperproliferate in culture when stimulated with lipopolysaccharide (LPS) or anti-IgM. We wished to further examine proliferation of resting B cells from the BXSB mouse model of lupus and mice with the Yaa allele, when activated with a number of stimuli. Our work demonstrates that: (1) resting B cells from mice containing the Yaa allele hyperproliferated compared to that seen with B cells from mice lacking the Yaa allele, (2) this hyperproliferation occurred whether cells were stimulated with phorbol myristate acetate/ionomycin, LPS, anti-IgM, or CD40L cross-linking, (3) this hyperproliferation is specific to B and not T cells. Taken together these data suggest that one mechanism by which the Yaa allele contributes to the accelerated onset of lupus in BXSB male mice is through its influence on B cell activation.
