Web21 Jun 2024 · T Follicular helper (Tfh) cells, a unique subset of CD4 + T cells, play an essential role in B cell development and the formation of germinal centers (GCs). Tfh differentiation depends on various factors including cytokines, transcription factors and multiple costimulatory molecules. WebAntibody production with the help of T cells is a fundamental aspect of humoral immune responses induced by thymus dependent antigens. Th2 cells were long considered to be the cells that provided help to B cells. It is now believed that the helper role is played by a newly found subset of CD4+ T cells TFH. The devel-opment of TFH is IL-21 dependent.
