dc.description.abstract | Neutrophils are the first-line defense against microbes. Enhancing the microbicidal activity of neutrophils could complement direct antimicrobial therapy for controlling intractable microbial infections. Previously, we reported that lysophosphatidylcholine (LPC), an endogenous lipid, enhances neutrophil bactericidal activity (Van et al. 2004. Nat. Med. 10: 161-167). In this study we show that LPC enhancement of neutrophil bactericidal activity is dependent on glycine, and is mediated by translocation of intracellularly located glycine receptor (GlyR) alpha 2 to the plasma membrane, and subsequent increase in azurophil granule-phagosome fusion/elastase release. LPC induced GlyR alpha 2-mediated [Cl-](i) increase, leading to transient receptor potential melastatin (TRPM)2-mediated Ca2+ influx. Studies using human embryonic kidney 293 cells heterologously expressing TRPM2 and neutrophils showed that TRPM2 channel activity is sensitive to [Cl-](i). Finally, LPC induced p38 MAPK phosphorylation in an extracellular calcium/glycine dependent manner. SB203580, a p38 MAPK inhibitor, blocked LPC-induced enhancement in Lucifer yellow uptake, azurophil granule-phagosome fusion, and bactericidal activity. These results propose that enhancement of azurophil granule-phagosome fusion via GlyR alpha 2/TRPM2/p38 MAPK signaling is a novel target for enhancement of neutrophil bactericidal activity. | - |
