Abstract

Sepsis is a life-threatening problem by organ dysfunction influenced by negative inflammatory responses and stimulated oxidative stress, which most of sepsis patients about 40–60% are accompanied with myocardial injury. Recently, stem cells derived exosomes could effectively apply in the numerous diseases by combined with natural therapeutic agents. In the present investigation, Sweroside functionalized with exosomes to control inflammatory responses by sepsis and significantly proved the function of depreciated myocardial injury-induced by LPS. The sweroside could have effectively delivered to cardiomyocytes cells via exosome carriers. The induced-SMI rats exhibited severe myocardial injury and apoptosis by in vivo experiments and treatment of sweroside-functionalized exosomes (SWO/EX) reassured the phenotypes. Importantly, SWO/EX significantly downregulated the ROS generation in the SMI rat models. The SOD and GSH activity were also suppressed in SMI rat models, and treated models with SWO/EXO could have effective liberating activity in the Rats. Meanwhile, SWO/EXO treated LPS-induced cardiomyocytes displayed that significant reduction of pro-inflammatory cytokines (IL-1β, IL-6 and TNF-α) levels and also increasing cell survival and prevented apoptosis. Thus, we demonstrate that MS-cells derived exosome with sweroside could have effectively impede sepsis-induced myocardial injury. SWO/EX formulations might be applied as a potent therapeutic agent for SMI therapy.
