Analysis of circulating Tfh cells and IL-21 levels after in vitro stimulation. PBMCs were isolated from healthy individuals and CE patients. Then they were stimulated with PBS or HF in vitro. The percentage of circulating Tfh cells was detected with flow cytometry. The levels of IL-21 and IL-4 were measured with cytometric bead array. a The percentage of circulating Tfh cells. b Level of IL-21 in the culture supernatant. c Level of IL-4 in the culture supernatant
