DPP4 and FCRL3 markers discriminate TFR’s from TFH cells. A Representative flow cytometry plots and B summary plot demonstrating expression of FCRL3+ cells among TFRs and TFHs. C Representative flow cytometry plots and D summary plot demonstrating the percentage of DPP4+ cells among TFRs and TFHs. E Boxplots with p-values of both FCRL3 and DPP4 expression. F Representative flow cytometry plots and G summary plot demonstrating expression of FCRL3+cells among Tregs and CD8 T cells. H Representative flow cytometry plots and I summary plot demonstrating expression of DPP4+ cells among Tregs, CD8 T cells and TFRs. P values were determined using Mann–Whitney U test
