Methylmercury Inhibits Nitric Oxide Production Mediated by Ca2+ Overload and Protein Kinase a Activation

, 2009
The importance of cytosolic free calcium level intracellular Ca2+, [Ca2+] i, in neutrophil activation prompted us to investigate changes in [Ca2+]i of neutrophils caused by methylmercury (MeHg), which has been shown to have immunomodulatory properties ...
