周细胞是血脑屏障中的细胞,其在阿尔茨海默病(AD)中退化,阿尔茨海默病是与神经血管功能障碍、淀粉样β-肽(Aβ)异常升高、tau病理学和神经元损失相关的神经障碍。然而,周细胞变性是否可以影响AD样神经变性并有助于疾病的发病机制仍然是未知的。我们发现,在Aβ前体蛋白过表达的小鼠中,周细胞丢失通过减少Aβ沉积前可溶性Aβ 40和A β 42从脑间质液中的清除,升高脑Aβ 40和A β 42水平,并加速淀粉样血管病和脑β淀粉样变性。我们进一步表明,周细胞缺乏导致tau病理学的发展和Aβ前体蛋白转基因小鼠中通常不存在的早期神经元损失,导致认知能力下降。我们的数据表明,在Aβ前体蛋白过表达小鼠中,周细胞控制AD样神经变性致病级联的多个步骤。因此,周细胞可能代表一种新的治疗靶点,以改变AD的疾病进展。 周细胞是血脑屏障中的细胞,随着阿尔茨海默病的发作而退化。在这里,Sagare等人表明,周细胞损失通过促进淀粉样蛋白β积累、tau病理学和神经元细胞的早期损失而导致疾病发作。
Pericytes are cells in the blood–brain barrier that degenerate in Alzheimer’s disease (AD), a neurological disorder associated with neurovascular dysfunction, abnormal elevation of amyloid β-peptide (Aβ), tau pathology and neuronal loss. Whether pericyte degeneration can influence AD-like neurodegeneration and contribute to disease pathogenesis remains, however, unknown. Here we show that in mice overexpressing Aβ-precursor protein, pericyte loss elevates brain Aβ40 and Aβ42 levels and accelerates amyloid angiopathy and cerebral β-amyloidosis by diminishing clearance of soluble Aβ40 and Aβ42 from brain interstitial fluid prior to Aβ deposition. We further show that pericyte deficiency leads to the development of tau pathology and an early neuronal loss that is normally absent in Aβ-precursor protein transgenic mice, resulting in cognitive decline. Our data suggest that pericytes control multiple steps of AD-like neurodegeneration pathogenic cascade in Aβ-precursor protein-overexpressing mice. Therefore, pericytes may represent a novel therapeutic target to modify disease progression in AD. Pericytes are cells in the blood–brain barrier that degenerate with the onset of Alzheimer's disease. Here, Sagare et al. show that pericyte loss contributes to disease onset by promoting amyloid-beta accumulation, tau pathology and early loss of neuronal cells.
