摘要混合谱系激酶结构域样蛋白(mixed lineage kinase domain-like protein, MLKL)是一种具有激酶结构域的假激酶，在程序性坏死的调控中发挥着重要作用。脑缺血后，MLKL作为受体相互作用蛋白3的底物蛋白发生寡聚化和磷酸化，继而从胞质转位至质膜，引起线粒体分裂和细胞膜破裂。MLKL还可通过诱导程序性坏死、直接激活炎性小体等途径介导脑缺血后的炎症反应，进而加重脑损伤。因此，阐明MLKL的生物学特性及其在脑缺血中的作用和机制，对脑缺血的治疗至关重要。

abstractsMixed lineage kinase domain-like protein (MLKL) is a pseudokinase with a kinase domain, which plays an important role in the regulation of necroptosis. After cerebral ischemia, MLKL, as the substrate protein of the receptor-interacting protein 3, undergoes oligomerization and phosphorylation, and then translocates from the cytoplasm to the plasmalemma, causing mitochondrial division and cell membrane rupture. MLKL can also mediate the inflammatory response after cerebral ischemia by inducing necroptosis and directly activating inflammasomes, thereby aggravating brain injury. Therefore, to clarify the biological characteristics of MLKL and its role and mechanism in cerebral ischemia is very important for the treatment of cerebral ischemia.
