Neutrophil Extracellular Traps Impair Intestinal Barrier Functions in Sepsis by Regulating TLR9-Mediated Endoplasmic Reticulum Stress Pathway

Neutrophil extracellular traps treatment induced intestinal epithelial monolayer barrier disruption and endoplasmic reticulum (ER) stress activation in a dose-dependent manner in vitro, and ER stress inhibition markedly attenuated intestinal apoptosis and tight junction injury.
