Fig. 1From: T follicular helper cells in patients with acute schistosomiasisFlow cytometry analysis of Tfh cells in acute schistosomiasis patients and healthy controls. Isotype controls were used to determine positive cells. All of the values were gated on CD4+ cells. a Values correspond to the percentage of CXCR5+CD4+ Tfh cells. b Comparison of the frequencies of CXCR5+CD4+ Tfh cells in healthy controls (HC) and schistosomiasis patients. c Values correspond to the percentage of PD-1+CXCR5+CD4+ Tfh cells. d Comparison of the frequencies of PD-1+CXCR5+CD4+ Tfh cells (*P <Â 0.01). e Values correspond to the percentage of ICOS+CXCR5+CD4+ Tfh cells. f Comparison of the frequencies of ICOS+CXCR5+CD4+ Tfh cellsBack to article page
