WebThe follicular T helper (Tfh) cells are a CD4+T cell subpopulation essential in the regulation of humoral immunity, specialized in supporting B cell maturation and immunoglobulin production in secondary lymphoid organs. Tfh cells were first described as a CXCR5-expressing population localizing in “tonsillar” follicles ( 10, 11 ). Web23 Aug 2014 · A distinct subset of CD4+ helper T (Th) cells, Tfh cell (Tfh) specialize in providing cognate help to antigen-specific B cells in germinal centers (GCs). Tfh cells play a key role in the formation of GCs and differentiation of GC B cells into plasma cells and memory B cells [ 23, 24 ].
