Naturally Occurring Enzyme Can Break Down Key Part of Alzheimer's Plaques
... the production of MMP-9 in astrocytes. They found astrocytes
close to amyloid plaques increased their MMP-9 production. Imaging studies also showed that MMP-9 levels increased around blood vessels laden with amyloid. "Astrocytes become activated around plaques as they develop, and then eventually form a wall...

become hypoxic, they are less able to mop up these transmitters, allowing the residual chemicals to accumulate and become toxic. The team is further investigating two key signalling molecules, which are very sensitive to fluctuations in oxygen leve...
