There is a constant need for better stroke treatments. Neurons at the periphery of an ischemic stroke affected brain tissue remains metabolically active for several hours or days after stroke onset. They later undergo mitochondrion-mediated apoptosis. It has been found that inhibiting apoptosis in the peripheral ischemic neurons could be very effective in the prevention of stroke progression. During stroke associated apoptosis, cytosolic c-Jun N-terminal Kinases (JNKs) and Bcl-2 family proteins translocate towards mitochondria and promote cytochrome release by interacting with the outer mitochondrion membrane associated proteins. This review provides an overview of the plausible interactions of the outer mitochondrial membrane Voltage Dependent Anion Channel, Bcl-2 family proteins and JNKs in cytochrome release in the peripheral ischemic stroke associated apoptotic neurons. The review ends with a note on designing new anti-stroke treatments.
对更好的中风治疗方法一直有需求。在缺血性中风影响的脑组织周边,神经元在中风发作后的数小时或数天内仍保持代谢活性。它们随后会经历线粒体介导的凋亡。已发现抑制周边缺血神经元中的凋亡在预防中风进展方面可能非常有效。在与中风相关的凋亡过程中,胞质c-Jun氨基末端激酶(JNKs)和Bcl-2家族蛋白向线粒体移位,并通过与线粒体外膜相关蛋白相互作用促进细胞色素释放。本综述概述了线粒体外膜电压依赖性阴离子通道、Bcl-2家族蛋白和JNKs在周边缺血性中风相关凋亡神经元的细胞色素释放中的可能相互作用。综述最后提到了设计新的抗中风治疗方法。
