QC exerted a suppressive effect on the differentiation of Tfh cells in vitro. (A) Quantification of the impact of various concentrations of QC on the proportion of Tfh cells by FCM. (B) Quantification of the impact of various concentrations of QC on the proportion of Treg cells by FCM. (C) Quantification of the impact of various concentrations of QC on Tfh cell differentiation on day 3 and day 7 by FCM (n = 5). (D) Quantification of the impact of various concentrations of QC on the proportion of senescent Tfh cells on day 7 by FCM (n = 5). (*P < 0.05, **P < 0.01)
