Figure 2. Surgery-induced M-MDSCs from lung cancer patients mediate expansion of Foxp3+ Treg in vivo.

Flow cytometric analysis of G-MDSCs, M-MDSCs and Treg in PBMCs of 111 lung cancer patients was performed at the time of preoperatoin (T1), intraoperation (T2), 1, 3 and 7 days (T3, T4 and T5) after tumor resection. Concentration of G-MDSCs A. M-MDSCs B. and Treg C. in PBMCs of lung cancer patients during perioperative period was calculated. D. Correlation between the concentration of M-MDSCs and Treg in lung cancer patients from T3 to T5 time point was analyzed.
