Background and Purpose: Respiratory diseases have become a global health problem and may lead to acute lung injury (ALI) in severe cases. ALI progression is associated with complex pathological changes; however, there are currently no effective therapeutic drugs. Excessive activation and recruitment of immunocytes in the lungs and the release of large amounts of cytokines are considered the primary causes of ALI, but the cellular mechanisms involved remain unknown. Therefore, new therapeutic strategies need to be developed to control the inflammatory response and prevent the further aggravation of ALI.Experimental Approach: Lipopolysaccharide was administered to mice via tail vein injection to establish an ALI model. Key genes regulating lung injury in mice were screened by RNA sequencing (RNA-seq), and their regulatory effects on inflammation and lung injury were assessed in in vivo and in vitro experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
