Fig. 1From: Cisplatin-based chemoradiation decreases telomerase-specific CD4 TH1 response but increases immune suppressive cells in peripheral bloodCirculating Treg cells before and after CRT. PBMCs from 20 patients treated with CRT for lung or head and neck cancer were taken before CRT and 1 month after. CD4+CD25+CD127lowFoxP3+Treg were analyzed by flow cytometry. A and D Representative plots for Treg (A) and CTLA-4+ Treg (D) in one patient. B and E Treg (B) and CTLA4+ Treg (E) rates variation after CRT, lines in red representing significant increase (> 20%) from baseline (n = 20). C and F Treg (C) and CTLA-4+ Treg (F) rates before and after CRT (n = 20). Results are shown as mean (standard deviation). **, p < 0.005 (Wilcoxon test)Back to article page
