ObjectiveTo investigate the regulation mechanism of neutrophils extracellular traps (NETs) on inflammatory diseases and to provide guidance for the treatment of related inflammatory diseases.MethodThe literatures about the relationship between NETs and inflammatory diseases were reviewed.ResultsNETs played an important role in sepsis, anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis, acute pancreatitis, inflammatory bowel disease, and other inflammatory diseases, which were related to the development or activity of the diseases. By regulating the formation of NETs pathway, reducing the production of NETs, we could ultimately reduce the inflammation of the disease.ConclusionNETs is involved in the course of sepsis, ANCA-associated vasculitis, acute pancreatitis, inflammatory bowel disease, and other inflammatory diseases, but further investigation and clinical inflammatory verification are needed.
