WebThe follicular T helper (Tfh) cells are a CD4+T cell subpopulation essential in the regulation of humoral immunity, specialized in supporting B cell maturation and immunoglobulin production in secondary lymphoid organs. Tfh cells were first described as a CXCR5-expressing population localizing in “tonsillar” follicles ( 10, 11 ). Web21 Apr 2024 · T follicular helper (Tfh) cells are a subset of memory CD4 + T cells located in secondary lymphoid tissues such as tonsil, spleen, and lymph node (LN). The process of Tfh cell differentiation is multistage, multifactorial, and also involves migration within the microenvironment of secondary lymphoid tissue.
