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 ]. WebJul 16, 2024 · It is well established that T follicular helper cells (Tfh), a subset of CD4 T cells, are essential to the development of neutralizing antibodies and that some of these cells, called circulating T follicular helper cells (cTfh), can be studied in the blood.
