Abstract:

It is widely believed that amyloid β-protein (Aβ) plays a core role in the pathogenesis of Alzheimer's disease (AD). Thus A β is one of main targets in the therapeutic explorations for AD. Currently, clearance of A β by passive immunotherapy is an important strategy for the treatment of AD. However, no consistent conclusions have been obtained from various clinical trails. We summarize the current situations of A β-directed passive immunotherapy for AD, and speculate that the failure of A β-directed passive immunotherapy for AD may be related to the intrinsic characteristics of A β-IgG glycosylation. Therefore, modifications of N-glycosylation on the Fc domain of A β-IgG and using a sequential administration mode of proinflammation-antiinflammation may be an effective strategy for passive immunotherapy for AD.

摘要:

β-淀粉样蛋白(Aβ)既是阿尔茨海默病发病机制中的重要病因,又是治疗的关键靶点之一。采取被动免疫途径清除脑组织Aβ是目前颇受临床关注的治疗策略。然而,各项临床试验至今尚未获得一致性的结论。对其研究现状的分析表明,Aβ被动免疫治疗失败的原因可能与Aβ-IgG免疫复合物所固有的糖基化修饰有关。因此,改良Aβ-IgG Fc片段N-糖基化修饰、采取促炎症反应-抗炎症反应序贯给药模式,可能是一种有效的被动免疫治疗策略。
