一般描述
与阿尔茨′海默病(AD)相关的脑和血管斑块主要由淀粉样蛋白β肽(Aβ)组成。Aβ衍生自淀粉样蛋白前体蛋白(APP)的切割，长度在39至43个氨基酸之间变化。Aβ [1-40]、Aβ [1-42]和Aβ [1-43]肽分别来自残基40、42和43后APP的裂解。切割是在最后一个APP处理步骤中通过γ-分泌酶进行的。Aβ[1-40]、[1-42]和[1-43]肽是AD中发生的斑块和缠结的主要成分。Aβ抗体和肽已被开发为阐明AD生物学的工具。

Presenilin-1 (PSEN1) is the catalytic subunit of the intramembrane protease γ-secretase and undergoes endoproteolysis during its maturation. Heterozygous mutations in the PSEN1 gene cause early-onset familial Alzheimer's disease (eFAD) and increase the proportion of longer aggregation-prone amyloid-β peptides (Aβ42 and/or

Abnormalities and impairments in axonal transport are suggested to strongly contribute to the pathological alterations underlying AD. The exact mechanisms leading to axonopathy are currently unclear, but it was recently suggested that APP expression itself triggers axonal degeneration. We used

Aging is associated with impairment of the paravascular pathway caused by the activation of astrocytes and depolarization of protein aquaporin‑4 (AQP4) water channels, resulting in the accumulation of protein waste, including amyloid β (Aβ), in the brain parenchyma. The secreted

Brain metastasis is a significant cause of morbidity and mortality in multiple cancer types and represents an unmet clinical need. The mechanisms that mediate metastatic cancer growth in the brain parenchyma are largely unknown. Melanoma, which has the highest rate

Despite decades of intense global effort, no disease-modifying drugs for Alzheimer's disease have emerged. Molecules targeting catalytic activities of γ-secretase or β-site APP-cleaving enzyme 1 (BACE1) have been beset by undesired side effects. We hypothesized that blocking the interaction between
