People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Green tea extract blocks formation of amyloid plaques in Alzheimers disease

RATE THIS! +9
Posted in Science on 10th Mar, 2013 10:49 PM by AlexMuller

Researchers at the University of Michigan have found a new potential benefit of a molecule in green tea: preventing the misfolding of specific proteins in the brain.

 

U-M Life Sciences Institute faculty member Mi Hee Lim and an interdisciplinary team of researchers used green tea extract to control the generation of metal-associated amyloid-β aggregates associated with Alzheimer’s disease in the lab.

 

The specific molecule in green tea, (-)-epigallocatechin-3-gallate, also known as EGCG, prevented aggregate formation and broke down existing aggregate structures in the proteins that contained metals — specifically copper, iron and zinc.

 

While many researchers are investigating small molecules and metal-associated amyloids, most are looking from a limited perspective, said Lim, assistant professor of chemistry and research assistant professor at the Life Sciences Institute.

 

“But we believe you have to have a lot of approaches working together, because the brain is very complex,” she said. Her team’s next step is to “tweak” the molecule and then test its ability to interfere with plaque formation in fruit flies.

 

The work was supported by the National Institutes of Health, Alzheimer’s Association, Alzheimer’s Art Quilt Initiative, American Heart Association, and a Graduate Research Fellowship from the National Science Foundation
