PD1 and ICOS expression on circulating follicular helper T cells (cTFH), CXCR5− memory CD4+ T cells, and CD4− T cells. (A) Summary graph showing PD1 and ICOS expression on cTFHs of DiGeorge patients and healthy controls. (B) Expression of PD1 on cTFHs, (C) CXCR5− memory CD4+ T cells, and (D) CD4− T cells with linear regression trendlines. * denotes significant correlation. (E) Change in PD1 expression over time on paired samples from two patients with DiGeorge syndrome on two consequent visits. (F) Expression of ICOS on cTFHs, (G) CXCR5− memory CD4+ T cells, and (H) CD4− T cells with linear regression trendlines. * denotes significant correlation.
