Have Scientists Found the Cause of Alzheimer’s?
Researchers say that they may have discovered the molecular-level cause of Alzheimer’s disease.
Scientists at the University of California–Riverside said in recent findings that the key to understanding Alzheimer’s may have to do with “tau” proteins that likely cause neurofibrillary tangles—which are found in the brains of Alzheimer’s patients. Previously, researchers suggested that amyloid plaques, which are a buildup of amyloid peptides, may be the cause. . . .
Researchers focused on the different structures a single molecule can manufacture, known as isomers.
they found that the “normal” tau had a different-handed form than in individuals who had plaques or tangles, and who were diagnosed with Alzheimer’s. The proteins also survived longer than is considered normal, the researchers said.
If a protein stays too long—generally more than 48 hours—some amino acids in the proteins convert into the “other-handed” isomer, they noted.
“If you try to put a right-handed glove on your left hand, it doesn’t work too well,” Julian said. “It’s a similar problem in biology; molecules don’t work the way they’re supposed to after a while because a left-handed glove can actually convert into a right-handed glove that doesn’t fit.”
