Abstract: Nitric oxide (NO) produced by inducible NO synthase (iNOS) during infection plays a crucial role in host defense mechanisms, via its antimicrobial and cytoprotective activities. Infection of Salmonella typhimurium in mice induces excessive production of NO, as a host defense response. We found much greater bacterial growth and apoptotic changes in iNOS-deficient (iNOS-/-) mice than in wild-type mice. However, the mechanism of NO-mediated cytoprotection during Salmonella infection remained unclear. An important…
