Circulating Angiogenic T Cells and Their Subpopulations in Patients with Systemic Lupus Erythematosus

Figure 1

FACS analysis of circulating Tang cell subsets. (a) Typical examples of CD31 and CXCR4 expression after gating on CD3+, CD4+, and CD8+ T cells from peripheral blood of representative patients with SLE. Quadrants were set according to the fluorescence signal provided by the isotype-matched control IgG antibodies. (b) Percentages of circulating Tang cell subsets (including CD31+CXCR4+ cells in CD3+, CD4+, and CD8+ T cells) in SLE patients and HC are shown. values were assessed by Mann-Whitney U test.
