In a healthy brain, the glial cells and the astrocytes are responsible for cleaning up the buildup of proteins around the neurons; however, they fail to accomplish this in Alzheimer's disease. The only FDA approved drug that is able to reverse the formation of plaque formation is called aduc...
Dysfunctional autophagy has been implicated in the pathogenesis of Alzheimer’s disease (AD). Previous evidence suggested disruptions of multiple stages of the autophagy-lysosomal pathway in affected neurons. However, whether and how deregulated autophag

These mice show an age-dependent increase in the level of Abeta40 and Abeta42 and in the number of amyloid plaques in the brain. Abeta40 and Abeta42 levels were measured, and amyloid burden and plaque number were quantified, in the hippocampus at the age of 4, 12, and 17 months in...
Frontiers in neuroscience, 14, 602642-602642 (2021-01-05) Alzheimer's disease (AD)-related degenerative decline is associated to the presence of amyloid beta (Aβ) plaque lesions and neuro fibrillary tangles (NFT). However, the precise molecular mechanisms linking Aβ deposition and neurological ...
This accumulation of AVs occurs before plaque deposition is observed to occur, and is not observed in diseases that do not feature Aβ deposition. One conclusion that has been drawn from these observations is that lysosomes themselves are a site of Aβ production. APP co-localizes with AVs, ...

CSF1R and its ligand CSF1 are main players of microglial development, survival, and metabolism [34] as well as crucial orchestrators of the inflammatory response in AD and other neurodegenerative disorders [35]. Noteworthy, the reduction of intraneuronal amyloid and plaque deposition, and ...
Alzheimer's is the most common form of dementia, and autopsies have long found its telltale signs in the brain: sticky plaque from an abnormal buildup of amyloid protein, and tangles of another protein named tau. Researchers find disease that mimics Alzheimer's This is the first FDA-approved...
New research points to tau, not amyloid-beta (Abeta) plaque, as the seminal event that spurs neuron death in disorders such as Alzheimer's disease. The finding, which dramatically alters the prevailing theory of Alzheimer's development, also explains why some people with plaque build-up in th...
