Direct detection of blood nitric oxide reveals a burn-dependent decrease of nitric oxide in response to Pseudomonas aeruginosa infection

Abstract

Burn injury is associated with severe immune dysfunction, including an anti-inflammatory state that occurs late after burn injury. While increased nitric oxide (NO) production is associated with severe infection and sepsis, the effect of burn trauma on these levels during a non-lethal infection remains unknown. We hypothesized that in a mouse model, 1) NO levels would be increased after infection without trauma and 2) burn injury would lead to decreased NO production even during infection
