Follicular B helper T (Tfh) cells support high affinity and long-term antibody responses. Here we found that within circulating CXCR5+ CD4+ T cells in humans and mice, the CCR7loPD-1hi subset has a partial Tfh effector phenotype, whereas CCR7hiPD-1lo cells have a resting phenotype. The circulating CCR7loPD-1hi subset was indicative of active Tfh differentiation in lymphoid organs and correlated with clinical indices in autoimmune diseases. Thus the CCR7loPD-1hi subset provides a biomarker to...[Show more]
