Acid aspiration is a frequent cause of ALI, leading to neutrophil sequestration, increased permeability, and deterioration of gas exchange. We investigated the role of platelet-neutrophil interactions in a murine model of acid-induced ALI. Acid aspiration induced P-selectin-dependent platelet-neutrophil interactions in blood and in lung capillaries.
Reducing circulating platelets or blocking P-selectin halted the development of ALI. Bone marrow chimeras showed that platelet, not endothelial, P-selectin was responsible for the injury.
The interaction of platelets with neutrophils and endothelia 299499 associated with TXA 2 formation, with detrimental effects on permeability and tissue function.
Activated platelets induced endothelial expression of ICAM-1 and increased neutrophil adhesion. Inhibition oey platelet-neutrophil aggregation improved gas exchange, reduced neutrophil recruitment and permeability, and prolonged survival. The key findings were confirmed in a sepsis-induced model of ALI.
