| 摘要: |
| 缺血性卒中是一种常见的脑血管疾病，通常是由于脑血液供应障碍引起脑组织氧供不足或缺血性坏死，严重影响患者健康，并给社会经济带来沉重负担。脑组织缺血性坏死会引发各种神经功能障碍，想要恢复绝非易事。近年来，通过调节免疫建立有利于缺血性卒中组织修复的免疫环境已成为目前研究热点。小胶质细胞是广泛分布在中枢神经系统（CNS）的先天免疫细胞，能对缺血性卒中后组织损伤的脑内微环境进行动态监控，并被分别激活为经典激活型（M1表型）和替代激活型（M2表型）两种状态，在缺血性卒中的神经修复中是一把双刃剑。M1和M2表型的小胶质细胞分别呈现促炎以及抗炎的特性，促进小胶质细胞从M1转化为M2极化表型有助于抑制神经炎症，是治疗缺血性卒中的重要干预策略。因此文章总结了小胶质细胞在缺血性卒中后的M1/M2表型转换的潜在机制，以及中药对极化过程的调节，为发现和探索潜在的免疫疗法提供新思路。 |

| Abstract: |
| Ischemic stroke is a common cerebrovascular disease,usually caused by cerebral blood supply disorders leading to insufficient oxygen supply or ischemic necrosis of brain tissue,which seriously affects patient health and brings a heavy burden to the social economy. Ischemic necrosis of brain tissue can cause various neurological disorders,and recovery is not an easy task. In recent years,establishing an immune environment conducive to ischemic stroke tissue repair by regulating immunity has become a current research hotspot. Microglia are innate immune cells widely distributed in the central nervous system(Central Nervous System,CNS),capable of dynamically monitoring the brain microenvironment of tissue damage after ischemic stroke,and are activated into two states:classical activation(M1 phenotype) and alternative activation(M2 phenotype). They are a double-edged sword in the neural repair of ischemic stroke. The M1 and M2 phenotypes of microglia exhibit pro-inflammatory and anti-inflammatory properties,respectively. Promoting the polarization phenotype of microglia from M1 to M2 helps to suppress neuroinflammation and is an important intervention strategy for treating ischemic stroke. Therefore,this article summarizes the potential mechanisms of M1/M2 phenotype transformation of microglia after ischemic stroke,as well as the regulation of polarization process by traditional Chinese medicine,providing new ideas for discovering and exploring potential immunotherapies. |
