Tfh induction
The inducible T-cell co-stimulator (CD278 or ICOS) is proven to provide a particularly critical signal for TFH cells since experimental mice deficient in ICOS are unable to develop any TFH. Additionally, it has been shown that ICOS induces the secretion of IL-21 cytokine by activated CD4 T cells and that IL-21 plays a crucial role in the development of TFH cells and germinal centers. Also Bcl-6 is a transcription factor identified in TFH cells, but it may have roles that extend beyo… Web20 Feb 2024 · The potent induction of Tfh cells, which enhances the duration and breadth of neutralizing antibodies by generating GCB cells and long-lived plasma cells, has been …
