概述
髓磷脂堿性蛋白(myelinbasicprotein,MBP)是髓鞘的主要成分,是誘導(dǎo)實驗性自身免疫性腦脊髓炎(experimentalautoimmuneencephalomyelitis,EAE)的重要抗原。EAE的病理學(xué)特征是:CNS血管周圍大量單個核細(xì)胞浸潤并造成炎性損傷,用MBP加佐劑主動免疫敏感動物或過繼轉(zhuǎn)移MBP特異性CD4+T細(xì)胞都可引發(fā)EAE。然而,將MBP致敏的T淋巴細(xì)胞直接注入實驗動物的CNS不能誘發(fā)EAE,但將同樣數(shù)量MBP致敏的T淋巴細(xì)胞由皮下或外周注射均可引起EAE,提示在外周針對MBP的淋巴細(xì)胞活化和活化后穿過血腦屏障是致病的重要因素。豚鼠髓磷脂堿性蛋白片段68-82是髓鞘堿性蛋白(MBP)的一個片段,結(jié)構(gòu)為tyr-gly-ser-leu-pro-gln-lys-ser-gln-arg-ser-gln-asp-glu-asn
生物活性

體外研究

Multiple sclerosis is the most common autoimmune disorder affecting the central nervous system. In this study, whole blood samples are analyzed for activation capacity and the activatability of CD4 + and CD8 + T-lymphocytes by human total myelin basic protein (MBP), human MBP 104-118 fragment, and guinea pig MBP (68-82) fragment. A significant increase in the number of activated T-lymphocytes was observed in the whole blood. For all three tested MBPs, this increase in activated CD4 + and CD8 + T-lymphocytes is statistically significant (p<0.01). However, this increase in activated T-cells is most prominent following incubation with human total MBP, followed by human 104-118 fragment; the smallest increase is observed following incubation with guinea pig MBP (68-82) fragment (human total MBP>huMBP-104-118>guinea pig MBP (68-82)).

體內(nèi)研究

Whether pretreatment with bee venom acupuncture (BVA) from the same day of MBP (68-82) immunization can affect the induction and progression of experimental autoimmune encephalomyelitis (EAE) and weight loss is examined. At 5-9 days after immunization, rats in the myelin basic protein (MBP) group start displaying partial loss of tail tonus (clinical signs, 0.5) in a freely moving environment. At 10-16 days after immunization, most of the rats in the MBP group display more severe symptoms of neurological deficit including paraparesis of the hindlimb, paraplegia, tetraparesis, and tetraplegia. In contrast, rats in the MBP?+?BVA group display relatively slight neurological deficits in a dose-dependent manner at 11-15 days after immunization, compared to the rats in the MBP group. The onset of symptoms is slightly delayed (BVA 0.8 mg/kg, 6.4±0.6 days) and the maximal clinical score is markedly decreased (BVA 0.25 mg/kg, 3.7±0.2; BVA 0.8 mg/kg, 2.8±0.3), compared to that in the MBP group. At this time, the mean body weight of rats in the MBP group is decreased as compared to that of rats in the normal group, but it is significantly increased in rats of the MBP?+?BVA group as compared to rats in the MBP group.
