WebMar 15, 2024 · T follicular helper (Tfh) cells, as a newly defined CD4+T cell subset, are critical for B cell activation and differentiation (9, 10). Tfh cells constitutively express the chemokine receptor CXCR5, which allows them to migrate into germinal center (GC) (11) and provide costimulation signals, such as CD40L and IL-21, to B cells (12). WebT follicular helper (Tfh) cells provide help to B cells, subsequently contributing to humoral rejection. Investigation of Tfh cells may be a useful strategy for assessing the risk and level of humoral rejection.

WebNov 30, 2024 · T follicular helper cells (Tfh cells) are a subset of CD4 + T lymphocytes that migrate to B cell follicles and promote the cognate B–T cell interaction; they then provide germinal center B cells with survival and differentiation signals that are essential for production of high affinity antibodies ( 9 ). WebFollicular Tregs (Tfr cells) inhibit antibody production, whereas follicular Th cells (Tfh cells) stimulate it. Tfr cells are found in blood; however, relatively little is known about the developmental signals for these cells or their functions.
