1 NADPH oxidase 2 inhibitor diphenyleneiodonium enhances ROS-independent bacterial phagocytosis in murine macrophages via activation of the calcium-mediated p38 MAPK signaling pathway. diphenyleneiodonium cytochrome b-245, beta polypeptide Mus musculus
2 Here, we found that the classic NOX2 inhibitor diphenyleneiodonium (DPI) induced uptake of E. coli by murine peritoneal macrophages through enhancing phagocytosis, and this effect was temperature-sensitive and attenuated by cytochalasin D as well as chemical inhibition of Syk and PLCgamma, two downstream kinases involved in actin polymerization during phagocytosis. diphenyleneiodonium cytochrome b-245, beta polypeptide Mus musculus
3 Here, we found that the classic NOX2 inhibitor diphenyleneiodonium (DPI) induced uptake of E. coli by murine peritoneal macrophages through enhancing phagocytosis, and this effect was temperature-sensitive and attenuated by cytochalasin D as well as chemical inhibition of Syk and PLCgamma, two downstream kinases involved in actin polymerization during phagocytosis. diphenyleneiodonium cytochrome b-245, beta polypeptide Mus musculus
4 The DPI-induced enhancement of phagocytosis was independent of NOX2 inhibition or ROS generation but depended on increased intracellular calcium and activation of the p38 MAPK signaling pathway. diphenyleneiodonium cytochrome b-245, beta polypeptide Mus musculus
