Correlation analysis of the levels of SEA specific IgG, IgG1 and IgG4 with the percentages of circulating Tfh cells in schistosomiasis patients (n = 11). Relationship of the percentages of CXCR5+ CD4+Tfh cells with (A) SEA specific IgG, (B) SEA specific IgG1, and (C) SEA specific IgG4. Relationship of the percentages of ICOS+CXCR5+ CD4+Tfh cells with (D) SEA specific IgG, (E) SEA specific IgG1, and (F) SEA specific IgG4. The percentages of PD-1+CXCR5+ CD4+Tfh cells were positively associated with (G) SEA specific IgG, (H) SEA specific IgG1, and (I) SEA specific IgG4 (p < 0.05).
