Lyn-deficient mice develop Ab-mediated autoimmune disease resembling systemic lupus erythematosus where hyperactive B cells are major contributors to pathology. In this study, we show that an inflammatory environment is established in Lyn(-/-) mice that perturbs several immune cell compartments and drives autoimmune disease. Lyn(-/-) leukocytes, notably B(More)
Ab-mediated autoimmune disease is multifaceted and may involve many susceptibility loci. The majority of autoimmune patients are thought to have polymorphisms in a number of genes that interact in different combinations to contribute to disease pathogenesis. Studies in mice and humans have implicated the Lyn protein tyrosine kinase as a regulator of(More)
Regulatory T cells (Tregs) are a subset of T lymphocytes that are responsible for suppressing the function of other immune cells, and preventing potentially harmful autoimmune responses. Studies in autoimmune-prone mice and human autoimmune diseases have shown reduced Treg number or function as a causative factor for the apparent loss of tolerance that(More)
Systemic lupus erythematosus (SLE, lupus) is a highly complex and heterogeneous autoimmune disease that most often afflicts women in their child-bearing years. It is characterized by circulating self-reactive antibodies that deposit in tissues, including skin, kidneys, and brain, and the ensuing inflammatory response can lead to irreparable tissue damage.(More)
We examined the role of NFκB1 in the homeostasis and function of peripheral follicular (Fo) B cells. Aging mice lacking NFκB1 (Nfκb1(-/-)) develop lymphoproliferative and multiorgan autoimmune disease attributed in large part to the deregulated activity of Nfκb1(-/-)Fo B cells that produce excessive levels of the proinflammatory cytokine interleukin 6(More)
