STING1 and inflammation: The therapeutic potential of CSE-P12 is further validated in a CLP-induced polymicrobial sepsis mouse model, where it significantly prolongs mouse survival and decreases lung inflammation.<h4>Conclusions</h4>CSE-P12 effectively targets pulmonary macrophages and exhibits potent anti-inflammatory activities in viral pneumonia and sepsis-induced acute lung injury by inducing autophagic flux to facilitate STING degradation.
