BackgroundInflammatory cytokine production contributes to lung injury after lung ischemia reperfusion and during lung transplant rejection. Although nitric oxide has been demonstrated to reduce lung injury associated with the adult respiratory distress syndrome, it remains unknown whether the mechanism of nitric oxide’s beneficial effects involves reducing lung macrophage inflammatory cytokine production. The purpose of this study was to determine whether nitric oxide downregulates lung macrophage inflammatory cytokine production.MethodsLung macrophages were harvested by bronchoalveolar lavage (106macrophage per milliliter from normal Sprague-Dawley rats, 6 animals per group) and treated under ex vivo tissue culture conditions with the nitric oxide releasing compound S-nitoso-N-acetyl-d, l-penicillamine (0, 10−5, 10−4, 10−3, 10−2mol/L) before induction of inflammatory cytokines with endotoxin, (50 ng/mL for 24 hours). Supernatants were assayed for inflammatory cytokine production (tumor necrosis factor α, interleukin-1β) by enzyme-linked immunosorbent assay.ResultsContinuous nitric oxide release by S-nitoso-N-acetyl-d, l-penicillamine decreased lung macrophage tumor necrosis factor-α and interleukin-1β production in a dose-dependent fashion (6 rats per group; data were analyzed for significance [p < 0.05] using two-way analysis of variance with Tukey’s post-hoc correction).ConclusionsNitric oxide decreases inflammatory cytokine production by lung macrophage. The mechanism of nitric oxide’s beneficial effects may be partially attributable to decreased production of inflammatory cytokines. Nitric oxide may serve an expanded role for reducing inflammatory cytokine production during acute lung injury, ischemia-reperfusion–induced inflammation, or lung transplant rejection.
