Washington--- Cat's claw, a plant extract sold to boost the immune system and

reduce inflammation, may work against alzheimer's disease, researchers said

friday.

Specifically it prevented the deposit of beta-amyloid plaques in rats' brains,

said Alan Snow, a pathology professor at the University of Washington in

Seattle.

Snow and collegues at the company he helped found, ProteoTech Inc. developed a

cat's claw compound they named PTI-00703. Tests in rats and in test tubes

indicate it interferes with the formation of these plaques, they told a meeting

of the biologists in Washington.
