Title	Retinal Pathological Features and Proteome Signatures of Alzheimer’s Disease
Description	Alzheimer’s disease (AD) pathologies were discovered in the easily accessible neurosensory retina. Yet, their specific nature, topographical distribution, and relationship with disease status remain undefined. Here, we histologically determined burden and spatial distribution of amyloid β-protein (Aβ42 ), intraneuronal scFvA13 + -Aβ species, macro- and microgliosis, and atrophy in superior- and inferiortemporal retinas of human donors with mild cognitive impairment (MCI) or AD versus normal cognition. AD and MCI patients had enhanced retinopathy, predominantly affecting inner layers and peripheral subregions, which quantitatively correlated with severity of cerebral amyloid, tau, and neurodegeneration, and cognitive scores. In advanced clinical stages AD retinopathy further affected central outer segments. Increased retinal macrogliosis and Aβ-phagocytosing microglia were detected in MCI and AD patients. Further, distinct proteome profiles of AD retinas were identified, displaying greater overlap with the temporal cortices than with hippocampi or cerebella. AD retinas exhibited upregulated inflammatory and neurodegenerative processes and downregulated oxidative-phosphorylation/mitochondrial, and photoreceptor-related pathways. This study identifies and maps AD retinopathy, demonstrating the quantitative relationship with brain pathology and cognition.
