ABSTRACT

Ischemic stroke (IS) is one of the most sinister diseases and the second leading cause of death in the world. Eugenol (EUG) is a natural and biologically active component that can be extracted from various plants. Studies have found that EUG can alleviate middle cerebral artery occlusion and reperfusion (MCAO/R) injury in mice, but the specific mechanism remains vague. Tripartite motif protein 59 (TRIM59) is a member of TRIM protein family, a group of E3 ubiquitin ligases. In this article, we conducted both in vivo and in vitro experiments to determine the effect of EUG on ischemia–reperfusion injury and to explore the underlying mechanisms by manipulating the expression of TRIM59. Results showed that EUG alleviates acute injury and promotes functional repair of mouse IS by enhancing the phagocytosis of microglia through up-regulating the TRIM59, activating the STAT3 pathway and promoting the expression of CD11b.
