The activation and sustained release of NETs by neutrophils stimulated by stimuli such as bacteria, fungi and inflammatory factors can lead to activation of peripheral platelets and damage to tissue cells. Several studies have demonstrated that the formation of NETs is one of the ways to promote the occurrence and development of inflammation, and inflammatory factors such as IL-8, IL-1β, and TNF-α are closely related to the formation of NETs. In recent years, the role of NETs in the occurrence and development of Severe Pneumonia (SP) has been continuously revealed. Therefore, we reviewed the current studies related to the mechanism of action of NETs associated with severe pneumonia. The aim is to provide a theoretical basis for evaluating the severity of severe pneumonia and searching for new targets for the treatment of severe pneumonia.展开更多
