Comparison of the phenotypes of CXCR3⁺ cTfh and CXCR3⁻ cTfh cells from individuals with HCV infection. (A) Representative flow cytometry plots of the phenotypes of CXCR3⁺ cTfh and CXCR3⁻ cTfh cells (n = 20). (B,C) Expression of PD-1 and ICOS in CXCR3⁺ cTfh and CXCR3⁻ cTfh cells (n = 20). (D,E) Expression of HLA-DR and Ki-67 in CXCR3⁺ cTfh and CXCR3⁻ cTfh cells (n = 20). (F,G) Expression of the transcription factors Bcl-6 and T-bet in CXCR3⁺ cTfh and CXCR3⁻ cTfh cells (n = 20). The paired t-test was used for the analysis.
