Astrocytes Can Clear Amyloid Plaques in Alzheimer’s Disease

Professor Erwin Loh, President of Royal Australasian College of Medical Administrators, posted on LinkedIn:

”Astrocytes Can Clear Amyloid Plaques in Alzheimer’s

Researchers have discovered a natural mechanism that clears existing amyloid plaques in the brain.

Researchers at Baylor College of Medicine have discovered a natural mechanism that clears existing amyloid plaques in the brains of mouse models of Alzheimer’s disease and preserves cognitive function.

The mechanism involves recruiting brain cells known as astrocytes, star shaped cells in the brain, to remove the toxic amyloid plaques that build up in many Alzheimer’s disease brains. Increasing the production of Sox9, a key protein that regulates astrocyte functions during aging, triggered the astrocytes’ ability to remove amyloid plaques.

The study, published in Nature Neuroscience, suggests a potential astrocyte-based therapeutic approach to ameliorate cognitive decline in neurodegenerative disease.
