Abstract:The tumor necrosis factor superfamily (TNFSF) member and cytokine known as B-cell activation factor belonging to the TNF-family (BAFF) has been identified as one of the key factors in the selection and survival of B cells. Overexpression of BAFF in mice leads to autoimmunity, whereas BAFF-deficient mice lack mature B cells. Although under normal concentrations of BAFF, non-self-reactive B cells survived and autoreactive B cells were deleted, a higher concentration of BAFF contributed to the survival of autorea… Show more
