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 ]. WebSep 7, 2024 · We show that anti-PD-1 therapy induces a population of circulating T follicular helper cells (cTfh) with enhanced B activation capacity, which participates in tumor response to treatment. Anti-PD-1 increases the number of tertiary lymphoid structures (TLS), which correlates with impaired tumor growth.
