A Drug Discovered In The Soil Of Easter Island Could Cure Alzheimer’s

Easter IslandAnnalee Newitz writes on io9.com:

Rapamycin is a bacterial byproduct discovered in the soil of Easter Island. It extends the lives of animals, and now two independent studies show that it can reverse the symptoms of Alzheimer’s. Is this the drug we’ve been waiting for?

A study published in the Journal of Biological Chemistry confirmed that mice with Altzheimers showed marked improvement in memory and cognition after being fed a rapamycin-enhanced diet. This study was released simultaneously with another, in PLoS One, which confirmed the results of the first in a different group of mice.

How does this wonder drug work? Physiologist Veronica Galvan, an author on the PLoS study, explained:

Rapamycin treatment lowered levels of amyloid-beta-42, a major toxic species of molecules in Alzheimer’s disease. These molecules, which stick to each other, are suspected to play a key role in the early memory failure of Alzheimer’s … The fact that we are seeing identical results in two vastly different mouse models of Alzheimer’s disease provides robust evidence that rapamycin treatment is effective and is acting by changing a basic pathogenic process of Alzheimer’s that is common to both mouse models. This suggests that it may be an effective treatment for Alzheimer’s in humans, who also have very diverse genetic makeup and life histories.
