Genetic deletion of the Src family tyrosine kinase Lyn in mice recapitulates human systemic lupus erythematosus, characterized by hyperactive B cell antigen receptor (BCR) signaling, splenomegaly, autoantibody generation and glomerulonephritis. However, the molecular regulators of autoimmunity in Lyn-deficient mice and in human lupus remain poorly characterized. Here, we report that conditional deletion of the membrane-cytoskeleton linker protein ezrin in B cells of Lyn-deficient mice (DKO mice) ameliorates B cell activation and lupus pathogenesis. B cells from DKO mice respond poorly to BCR stimulation, with severe downregulation of major signaling pathways. DKO mice exhibit reduced splenomegaly as well as significantly lower levels of autoantibodies against a variety of autoantigens, including dsDNA, histone and chromatin. Leukocyte infiltration, and deposition of IgG and complement component C3 in the kidney glomeruli of DKO mice is markedly reduced. Our data demonstrate that ezrin is a novel molecular regulator of B cell-associated lupus pathology.
