Neutrophil Extracellular Traps Are Pathogenic in Ventilator-Induced Lung Injury and Partially Dependent on TLR4

Figure 2

Immunofluorescence staining of Cit-H3 and NE on lung sections. NETs, defined as colocalized DNA (blue), citrullinated histone-3 (Cit-H3) (green), and neutrophil elastase (NE) (red), presented in lungs sections of VILI model (HTV). However, there was no obvious staining in CON group and LTV group.
