WebIn humans, the majority of T cells in adults are memory cells. The subset composition of human T cell memory is specific to the tissue site; in mucosal, exocrine, and barrier sites, T RM cells predominate, whereas lymphoid sites contain circulating effector and central memory (T EM and T CM) along with T RM subsets ( 19, 25, 26 ). WebT follicular helper (Tfh) cells are specialized to provide help to B cells and to induce durable antibody response. Our knowledge on the biology of Tfh cells and their contribution to disease has significantly increased in the past decade.
