老年性黄斑变性(AMD)和青光眼是视网膜的退行性疾病,在发达国家是导致不可逆性失明的重要原因。阿尔茨海默病(AD)是老年人最常见的痴呆症,常与AMD和青光眼有关。阿尔茨海默病的基本特征是淀粉样蛋白β(A-tau)在细胞外的蓄积和过度磷酸化的tau在细胞内的沉积(p-tau)。神经炎症和脑铁代谢紊乱伴随着Aβ和p-tau的沉积,共同导致进行性神经元死亡和痴呆。老年性黄斑变性的标志玻璃体中Aβ和铁的积聚,以及视网膜神经节细胞中Aβ和p-tau的积聚,是青光眼的主要视网膜细胞类型,并伴有炎症,提示病理重叠。视觉异常在阿尔茨海默病中很突出,被认为是在认知能力下降之前发展起来的。一些是由视皮层退化引起的,另一些是由于RGC丢失或AMD相关的视网膜退化引起的。在这里,我们回顾了最近关于Aβ、p-tau、慢性炎症和铁代谢紊乱作为联系这三种退行性疾病的常见致病机制的最新信息,以及铁螯合作为这些疾病的常见治疗选择。此外,还讨论了Prion蛋白在Aβ介导的毒性中的作用,以及矛盾的是,在神经保护中的作用。
Age-related macular degeneration (AMD) and glaucoma are degenerative conditions of the retina and a significant cause of irreversible blindness in developed countries. Alzheimer’s disease (AD), the most common dementia of the elderly, is often associated with AMD and glaucoma. The cardinal features of AD include extracellular accumulation of amyloid β (Aβ) and intracellular deposits of hyper-phosphorylated tau (p-tau). Neuroinflammation and brain iron dyshomeostasis accompany Aβ and p-tau deposits and, together, lead to progressive neuronal death and dementia. The accumulation of Aβ and iron in drusen, the hallmark of AMD, and Aβ and p-tau in retinal ganglion cells (RGC), the main retinal cell type implicated in glaucoma, and accompanying inflammation suggest overlapping pathology. Visual abnormalities are prominent in AD and are believed to develop before cognitive decline. Some are caused by degeneration of the visual cortex, while others are due to RGC loss or AMD-associated retinal degeneration. Here, we review recent information on Aβ, p-tau, chronic inflammation, and iron dyshomeostasis as common pathogenic mechanisms linking the three degenerative conditions, and iron chelation as a common therapeutic option for these disorders. Additionally discussed is the role of prion protein, infamous for prion disorders, in Aβ-mediated toxicity and, paradoxically, in neuroprotection.
