Sepsis is a common and critical complication in surgical patients that often leads to multiple organ failure syndrome (MOFS), including acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Despite intensive supportive care and treatment modalities, the mortality of these patients remains high. In this study, we investigated the role of Burton's tyrosine kinase (BTK), a member of the Btk/Tec family of cytoplasmic tyrosine kinases, in the pathogenesis of sepsis, and evaluated the protective effect of in vivo Btk RNA interference in a mouse model of cecal ligation and puncture (CLP)-induced sepsis. After intratracheal injection of Btk siRNA, the mice were then subjected to CLP to induce sepsis. The results demonstrated that this approach conferred potent protection against sepsis-induced ALI, as evidenced by a significant reduction in pathological scores, epithelial cell apoptosis, pulmonary edema, vascular permeability, and the expression of inflammatory cytokines and neutrophil infiltration in the lung tissues of septic mice. In addition, RNA interference of Btk significantly suppressed p-38 and iNOS signaling pathways in transduced alveolar macrophages in vitro. These results identify a novel role for BTK in lethal sepsis and provide a potential new therapeutic approach to sepsis and ALI.
