The IL-10 expression by non-Tfr Treg cells and Tfr cells was lower in healthy controls and significantly higher in ARDS PBMCs and ARDS mini-BAL (Fig. 3c) . The higher IL-10 and TGF-β in ARDS mini-BAL compared to autologous PBMCs likely indicated that the Tfr and non-Tfr Treg cells in the lung infiltrates were further activated. As a result, the suppression studies were performed using Tfr cells from PBMCs. Since the Tfr cells from Fig. 2 The frequency of Treg cells and Tfr cells in the mini-BAL from ARDS patients at day 1, day 2, and day 3 after disease onset. NS not significant Fig. 3 The expression of inhibitory molecules by non-Tfr Treg cells and Tfr cells from healthy controls and ARDS patients.	./cache/cord-006773-61ezrjuq.txt	./txt/cord-006773-61ezrjuq.txt
