Summary: Plaque formation can cause spheroid-shaped swellings to build up along axons near amyloid plaque deposits. The swellings are caused by lysosomes, which digest cellular waste. As the swelling grows, it can block the transmission of signals from one area of the brain to another. Source: Yale The formation of amyloid plaques in the brain …
Summary: Researchers have identified a protein that could be harnessed to help microglia in the brain ward off Alzheimer’s disease and other neurodegenerative diseases. Source: The conversation Many neurodegenerative diseases, or conditions resulting from the loss of function or death of brain cells, remain largely incurable. Most available treatments target only one of the multiple …
