Background

Mechanical ventilation causes ventilator-induced lung injury in animals and humans. Mitogen-activated protein kinases have been implicated in ventilator-induced lung injury though their functional significance remains incomplete. We characterize the role of p38 mitogen-activated protein kinase/mitogen activated protein kinase kinase-3 and c-Jun-NH(2)-terminal kinase-1 in ventilator-induced lung injury and investigate novel independent mechanisms contributing to lung injury during mechanical ventilation.

Methodology and principle findings

C57/BL6 wild-type mice and mice genetically deleted for mitogen-activated protein kinase kinase-3 (mkk-3(-/-)) or c-Jun-NH(2)-terminal kinase-1 (jnk1(-/-)) were ventilated, and lung injury parameters were assessed. We demonstrate that mkk3(-/-) or jnk1(-/-) mice displayed significantly reduced inflammatory lung injury and apoptosis relative to wild-type mice. Since jnk1(-/-) mice were highly resistant to ventilator-induced lung injury, we performed comprehensive gene expression profiling of ventilated wild-type or jnk1(-/-) mice to identify novel candidate genes which may play critical roles in the pathogenesis of ventilator-induced lung injury. Microarray analysis revealed many novel genes differentially expressed by ventilation including matrix metalloproteinase-8 (MMP8) and GADD45alpha. Functional characterization of MMP8 revealed that mmp8(-/-) mice were sensitized to ventilator-induced lung injury with increased lung vascular permeability.

Conclusions

We demonstrate that mitogen-activated protein kinase pathways mediate inflammatory lung injury during ventilator-induced lung injury. C-Jun-NH(2)-terminal kinase was also involved in alveolo-capillary leakage and edema formation, whereas MMP8 inhibited alveolo-capillary protein leakage."xsd:string
