Web15 Apr 2024 · Glycolysis increases T helper cytokine expression, and HIF promoted glycolysis in T helper cells via TCR or cytokine stimulation, as well as their production of cytokines that direct antibody class switching. Indeed, IFN-γ elaboration by HIF-deficient in vivo-generated Tfh cells was impaired. 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.
