Our study revealed a novel regulatory mechanism of XBJ in sepsis-induced EC dysfunction and ALI. The compounds in XBJ inhibited the activity of ACLY, thereby inhibiting the expression of RIG-I by reducing the acetylation of transcription factor MYB, leading to the alleviation of EC activation and lung injury induced by sepsis. Our findings provide a theoretical basis for the clinical application of XBJ and shedding light on novel therapeutic targets for treating sepsis.
