Changes of Tfr cells in renal graft tissues. (a) The number of Tfh cells and Tfr cells in renal graft tissues of CRAD patients was detected using immunofluorescence staining. (b) There is no statistical difference with the number of Tfh cells between AMR group and non-AMR group. (c) The ratio of Tfr cells in renal graft tissues of AMR group was significantly lower than that of non-AMR group. Two-sided Wilcoxon rank sum test: *p < 0.05 (n = 10) versus Non-AMR. Values are mean ± SD.
