The function of BAFF on T helper cells in autoimmunity

Cytokine Growth Factor Rev. 2014 Jun;25(3):301-5. doi: 10.1016/j.cytogfr.2013.12.011. Epub 2013 Dec 24.

Abstract

B cell-activating factor belonging to the TNF family (BAFF) exerts its pathogenic role in supporting the survival and proliferation of B cells, regulating class switch recombination as well as the selection of autoreactive B cells. Overexpression of BAFF induces a dramatic expansion of activated B cells, particularly marginal zone B cells, as well as hypergammaglobulinemia, autoantibody production and immune complex deposition. However, in addition to its effect on B cells, recent work has also demonstrated that BAFF can promote T cell activation, proliferation and differentiation. In this review, we have discussed the recent progress on the function and role of BAFF on T cells and T cell-mediated diseases.

Keywords: BAFF; T helper cells; Tfh cells; Th17; Treg cells.
