Figure Legend Snippet: TRPM7 activity is dispensable for phagocytosis but indispensable for reactive oxygen species (ROS) production of human neutrophils. (A) Phagocytic activity of neutrophils was measured using fluorescent Escherichia coli particles together with human whole blood pre-incubated with NS8593 (30 µM, red), TG100-115 (20 µM, blue), or a combination of IPI-549 and nemiralisib (IPI/NEM, 160/100 nM, gray) for 30 min or vehicle (Ctrl, black) and analyzed by flow cytometry (n = 5). Representative dot plot analysis (left panel) and quantification of phagocytic activity (right panel).
