WebTh2 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. TFH with clear phenotype of CD4+CXCR5+ is predominantly located in B cell follicles, and characterized by the secretion of IL-21 ... Web17 Jan 2024 · T helper cells (Th) have a wide range of effector functions and can differentiate into many different subtypes, such as Th1, Th2, Th17, TfH cells and regulatory T cells. They become activated when they are presented with peptide antigens on MHC Class II molecules. These are expressed on the surface of APCs.
Web20 Apr 2009 · Although our experiments suggest that a Th2 cell can become a TFH cell, they do not address whether this conversion is a final step in a linear pathway. Instead, there may be plasticity between TFH and Th2 cells, wherein different signals might regulate the reversible transition between the two states. Web25 Feb 2024 · These dual transcriptional regulator-expressing cells are defined as subsets of Tfh cells named Tfh1, Tfh2 and Tfh17, respectively.
