Fig. 2From: Increased circulating Tfh to Tfr ratio in chronic renal allograft dysfunction: a pilot studyThe frequency of cTfh and cTfr cells and the level of associated factors between CAD group and stable group. Squares refer to chronic allograft dysfunction (CAD) group, cycles refer to stable renal function group; a cTfh: CXCR5+Foxp3− on CD4+ cells; b cTfr: CXCR5+Foxp3+ on CD4+ cells; c cTfh to cTfr ratio; d Tregs: CD25+Foxp3+ on CD4+ cells; e CXCR5+PD-1+ on CD4+ cells; f PD-1+ on CXCR5+CD4+ cells; g CXCR5+ICOS+ on CD4+ cells; h ICOS+ on CXCR5+CD4+; i CXCR5+STAT3+ on CD4+ cells; j CXCR5+STAT5+ on CD4+ cells; k STAT3+ on CXCR5+CD4+ cells; l STAT5+ on CXCR5+CD4+ cells; m CXCR5+STAT4+ on CD4+ cells; n STAT4+ on CXCR5+CD4+ cells; o CXCR5+IL-21+ on CD4+ cells; p IL-21+ on CXCR5+CD4+ cells; q The serum level of CXCL13; r The serum level of TGF-βBack to article page
