Circulating follicular helper t cells

WebT follicular helper (Tfh) cells are a subset of CD4-positive T helper cells that are involved in the humoral response [ 1 ]. Tfh cells are found in secondary lymphoid tissues, including tonsils, spleen, and lymph nodes. The role of Tfh cells is to trigger germinal center (GC) B cells into antibody-secreting plasma and memory B cells [ 2,3 ]. 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).

Anti-PD-1 increases the number of tertiary lymphoid structures (TLS), which correlates with impaired tumor growth. WebFollicular helper T cells play a key role in B cell differentiation into antibody-producing cells outside GCs as well. Recent studies demonstrate that there are different subsets of Tfh cells in humans and mice. BCL6 + Tfh cells are required for B cell priming for extrafollicular antibody production in a T-dependent immune response ( 53 ).
