More than three decades of research on Alzheimer’s disease have not produced any major treatment advances for those with the disorder, according to a UCLA expert who has studied the biochemistry of the brain and Alzheimer’s for nearly 30 years. “Nothing has worked,” said Steven Clarke, a distinguished professor of chemistry and biochemistry. “We’re ready for new ideas.” Now, Clarke and UCLA colleagues have reported new insights that may lead to progress in fighting the devastating disease.
Scientists have known for years that amyloid fibrils — harmful, elongated, water-tight rope-like structures — form in the brains of people with Alzheimer’s, and likely hold important clues to the disease. UCLA Professor David Eisenberg and an international team of chemists and molecular biologists reported in the journal Nature in 2005 that amyloid fibrils contain proteins that interlock like the…
