Changes of the Ki67 expression of recent thymic emigrant (RTE), mature naive (MN), CD31+, and CD31 memory regulatory T cells (Tregs)/responder T cells (Tresps) with age in healthy volunteers (n = 94) and SLE patients, divided into patients treated with glucocorticoids (n = 46) or not (n = 32). The percentages of Ki67+ cells within RTE, MN, CD31+, and CD31 memory Tregs/Tresp was estimated in healthy volunteers (black diamonds) and in SLE patients who were treated with glucocorticoids (red diamonds) or not (green diamonds). An age-independent significantly decreased (red downward arrow) percentage of Ki67+ cells was detected in CD31+ and CD31 memory Tregs (marked by red p* values) in glucocorticoid-treated versus untreated SLE patients (a). A similarly reduced expression of Ki67+ cells in CD31+ and CD31 memory Tresps of glucocorticoid-treated SLE patients was not detected (b)
