雌激素对实验性自身免疫性脑脊髓炎免疫性保护机制的研究进展

Immunoprotective mechanisms of estrogen on experimental autoimmune encephalomyelitis:research advances

实验性自身免疫性脑脊髓炎(EAE)是一种主要由特异性致敏CD4+T细胞介导的自身免疫性疾病,其主要特征是中枢神经系统(CNS)单个核细胞浸润以及脱髓鞘。由于与多发性硬化(MS)有着极其相似的组织病理学特征和免疫学特征,EAE动物模型作为经典模型已被广泛用于MS的相关研究。近年来,雌激素作为免疫调节剂用于治疗复发-缓解型MS已进入Ⅱ期临床试验。大量前期动物实验研究证实,高浓度雌激素能缓解EAE,但其具体的作用机制有待进一步阐明。本文主要就雌激素对EAE的免疫性保护机制做简要综述。

Experimental autoimmune encephalomyelitis （EAE） is an autoimmune disease model mediated by specific allergenic CD4^＋T cell and accompanied by mononuclear cells invasion in central nervous system （CNS） and demyelination. Similar to the histopathology and immune characters of multiple sclerosis（MS）, EAE has been used as a classical animal model for the study of MS. In recent years, as an immune regulator for the treatment of relapsing-remitting MS, study of estrogen has entered the pre-clinical phaseⅡtrials. Larger numbers of studies have verified that high concentration of estrogen could improve EAE. However, the specific mechanisms are still in controversy. For these considerations, this review summarizes the protective mechanisms of estrogen in EAE.
