The frequency of Tfh cells and CXCR5 expression on total CD4+ T cells. (A) The percentage of peripheral CD3+, CD4+ and CD8+ T cells in children with HSP. (B) CXCR5 expression on total CD4+ T cells, the percentage and absolute number of Tfh cells in children with HSP. (C) PD-1 expression on CD4+CXCR5+ and CD4+CXCR5− cells in children with HSP compared with HCs. Each dot represents an independent individual. ns: not significantly different, * p < 0.05. CD: cluster of differentiation, CXCR5, C-X-C chemokine receptor type 5, HC: Healthy controls, AP: Acute Henoch-Schonlein Purpura, PD-1, programmed cell death protein 1, Tfh, T follicular helper
