WebFollicular helper T (Tfh) cells are the helper T-cell subset that localizes in germinal centers within secondary lymphoid organs. They support B cells to produce high-affinity antibodies and generate B-cell memory. By contrast, follicular regulatory T (Tfr) cells localize in germinal centers to suppress B-cell responses.
WebMar 24, 2024 · Follicular T helper (Tfh) and regulatory (Tfr) cells are distinct subsets of CD4 + T lymphocytes, regulating humoral immune responses in the germinal center. It is widely accepted that dysregulated Tfh and Tfr cells are associated with autoimmunity. Here, we evaluated the frequencies of circulating CXCR5 + PD-1 + Tfh (cTfh) and … WebDisplay statistics.
