WebT follicular helper (TFH) cells are characteristically defined by their CXCR5 positivity and homing to B cell follicles in secondary lymphoid organs (SLO). Web10 Jan 2024 · Aqrawi et al. showed a trend for an increased proportion of blood Tfh cells in SS patients, defined as programmed death-1 (PD)-1 + CXCR5 + CD4 + T cells [ 1 ]. This population is probably heterogeneous in including CXCR5 + FoxP3 + Tfr cells and excluding PD-1 – CXCR5 + Tfh cells [ 3, 4] ( Fig. 1a ).
