Role of TNF-alpha in lung tight junction alteration in mouse model of acute lung inflammation.

abstract：BACKGROUND:During a lipopolysaccharide-induced lung inflammation, a massive accumulation of neutrophils occurs, which is normally cleared by macrophage phagocytosis following neutrophil apoptosis. However, in cases of extensive apoptosis the normal clearance system may fail, resulting in extensive neutrophil secondary ...
