Molecular and genetic landscapes of retina and brain microglia in neurodegenerative diseases

3 months 3 weeks ago
Microglia-driven dysregulation has emerged as a significant underlying mechanism in many neurodegenerative diseases, such as age-related macular degeneration (AMD) and Alzheimer's disease (AD). Although both brain and retinal microglia originate from the yolk sac, it is uncertain whether they share molecular similarities or genetic and molecular foundations related to neurodegenerative diseases. In this study, we examine the transcriptomic and epigenetic profiles of retina and brain microglia...

RABGAP1 is a sensor that facilitates the sorting and processing of amyloid precursor protein

3 months 3 weeks ago
A hallmark of Alzheimer's disease (AD) is the accumulation of extracellular amyloid-β plaques in the brain. Amyloid-β is a 40-42 amino acid peptide generated by proteolytic processing of amyloid precursor protein (APP) via membrane-bound proteases. APP is a transmembrane protein, and its trafficking to sites of proteolysis represents a rate-limiting step in AD progression. Although APP processing has been well-studied, its trafficking itinerary and machinery remain incompletely understood. To...
