The Ttc7Fsn/Fsn Mutation Results In Hyperactivation Of Lymphocytes And Overproduction Of Il-4 Leading To The Development Of Systemic Autoimmunity, Beth Lindroth Hill
Electronic Theses and Dissertations
Ttc7fsn/fsn mice exhibit systemic autoimmunity characterized by hyperactivated B cells, increased interleukin-4, autoantibodies, kidney disease and reduced lifespan. Because the pathology is similar to systemic lupus erythematosus, Ttc7fsn/fsn mice are a useful model with which to study early events that lead to autoimmune disease. Although the Ttc7fsn mutation has been identified the gene function is unknown. The phenotype of Ttc7fsn/fsn mice mimics the Th2 autoimmunity of the IL-4 transgenic (Erb et al 1997). It was previously unknown whether the over-production of IL-4 was an intrinsic defect of Ttc7fsn/fsn lymphocytes that led to autoimmunity, or, whether …
