Green Tea and Red Laser Attack Alzheimer's Plaques

Posted November 05, 2011 1:30 PM

From New Scientist - Online News:

It may sound like a strange brew, but green tea and red light could provide a novel treatment for Alzheimer's disease. Together, the two can destroy the rogue "plaques" that crowd the brains of people with the disease. The light makes it easier for the green-tea extract to get to work on the plaques.

Andrei Sommer at the University of Ulm in Germany, and colleagues, have previously used red light with a wavelength of 670 nanometres to transport cancer drugs into cells. The laser light pushes water out of the cells and when the laser is switched off, the cells "suck in" water and any other molecules, including drugs, from their surroundings.

Please, do not underestimate the importance of such research. As the average age of the elderly population creeps upward, such problems increase exponentially. Biochemistry treats Alzheimers, dementia, Parkinsons as one and the same. You, me or your loved ones are statistically likely to be hit by it.

I follow the basic research like this for 20-30 years. Some progress is made. But it is a darned stubborn conundrum. The one definitive result of the last 5 years is a genetic one. The garbage removal for the amyloid plaques is genetically inferior for some 30% of the population, any population. Great. Once you know what the (partial) problem is, correction follows in due time.

But there were many hopeful moments, and no payout . That is the nature of the basic research, or for the matter of fact, your tinkering with a favorite gizmo.

Good basic research!
