To further examine the effect of IL-10 on the cellular milieu of the lungs during LPS-induced ALI, we evaluated the histology of the injured lungs according to 5 major dimensions: alveolar neutrophils, interstitial neutrophils, hyaline membranes, proteinaceous debris filling the airspaces, and alveolar septal thickening27. This evidence concerns the gene IL10 and acute respiratory distress syndrome.
