Because we noticed that 18 h exposure to Proleukin led to STAT‐5 phosphorylation in CD25+CD127+CD4+ T cells that mirrored that in Treg (CD25+CD127–CD4+) (both frequency and MFI) (Supporting information, Fig. 5), we evaluated the effect of 18‐h VLDP on the expression of CD25, CTLA‐4 and FoxP3 by the CD25+CD127+CD4+ T effector cell population in the blood of AILD patients (Fig. 2b). This evidence concerns the gene IL7R and angioimmunoblastic T-cell lymphoma.
