Additional file 2: of Increased circulating Tfh to Tfr ratio in chronic renal allograft dysfunction: a pilot study

Figure S2. The frequency of cTfh cells and the level of associated-factor between BPR group and stable group. Squares refer to biopsy-proven rejection (BPR) group, cycles refer to stable renal function group; (A) cTfh: CXCR5+Foxp3− on CD4+ cells; (B) Tregs: CD25+Foxp3+ on CD4+ cells; (C) CXCR5+PD-1+ on CD4+ cells; (D) PD-1+ on CXCR5+CD4+ cells; (E) CXCR5+STAT4+ on CD4+ cells; (F) STAT4+ on CXCR5+CD4+ cells; (G) CXCR5+IL-21+ on CD4+ cells; (H) IL-21+ on CXCR5+CD4+ cells; (I) The serum level of CXCL13; (J) The serum level of TGF-β.
