Neurobiological links between Alzheimer's disease and reward system dysfunction
Alzheimer's disease (AD) is a highly prevalent progressive neurodegenerative disorder with unclear etiology, complex symptoms, and limited treatment options. Early pathological processes in AD emerge long before the onset of overt cognitive and motor symptoms and involve the accumulation of amyloid-β oligomers and neurofibrillary tangles, accompanied by neuroinflammation and neuronal loss. Importantly, the brain reward system comprises cortical and subcortical structures that share neurochemical...
Pan-neurodegeneration proteomics reveals disease subtypes and molecular signatures
Neurodegenerative diseases (NDs) pose clinical challenges due to their complexity and molecular heterogeneity. Here, we present a pan-neurodegeneration atlas (PanNDA) from multilayer, deep proteomic analysis of 2,279 human brain samples spanning 6 major NDs: Alzheimer's disease (AD), Lewy body dementia (LBD), frontotemporal lobar degeneration with TDP-43 pathology, progressive supranuclear palsy with tau pathology, vascular dementia, and Parkinson's disease. PanNDA integrates data from whole...
Amyloid precursor protein derivatives differentially alter the microRNA cargo of astrocyte-derived extracellular vesicles
Alterations to the protein and microRNA cargo of extracellular vesicles (EVs) occur in Alzheimer's disease (AD) and may contribute to disease progression. We previously showed that ingestion of amyloid-beta (Aβ) by both murine and human astrocytes leads to alterations to the protein cargo of EVs that induce significant neuronal impairment and apoptosis. Here, we hypothesised that pathological changes to the microRNA cargo of astrocyte-derived EVs (ADEVs) would also occur following exposure of...
