摘要:

阿尔茨海默病是一种常见的神经退行性疾病,临床主要表现为进行性记忆能力丧失和整体认知能力下降。两种典型的病理特征为在脑内检测到的老年斑和神经纤维缠结,分别由大量沉淀的淀粉样蛋白肽和过度磷酸化的Tau蛋白组成。除此之外还有神经炎性反应以及神经元广泛丢失等其他病理特征。在过去的几十年间虽然人们已经对阿尔茨海默病进行了大量的研究,但是其病因和发病机制仍不明确,至今也没有理想的治疗药物和根治方法。本综述介绍在临床前研究中使用的各种转基因动物模型的各自特点,及其目前在临床前研究中的应用情况,为未来的实验研究提供理论依据。

Abstract:

Alzheimer's disease is a common neurodegenerative disease characterized by progressive memory loss and overall cognitive decline. Two typical pathological features are senile plaques and neurofibrillary tangles detected in the brain, which consist of large amounts of precipitated amyloid peptide and hyperphosphorylated Tau protein, respectively. In addition, there are other pathological features such as neuroinflammatory response and extensive loss of neurons. In the past decades, a lot of research has been done on Alzheimer's disease, but its etiology and pathogenesis are still unclear, and there is no ideal treatment or radical cure. This review introduced the characteristics of various transgenic animal models and their current application in preclinical studies, in order to provide theoretical basis for future experimental studies.

Key words: Alzheimer's disease, Transgenic mouse, Animal models, β-amyloid protein, Tau protein
