Laser Destroys Alzheimer's Protein

Alzheimer's and Dementia Weekly
Researchers have found that a technique used to visualize amyloid fibers in the laboratory might have the potential to destroy them in the clinic. The technique involves zapping the fluorescently-tagged fibers with a laser, which can inhibit their growth and degrade them. This study, appearing in this week's JBC, may offer a non-drug alternative to treat amyloid-based disorders like Alzheimer, Parkinson, and Huntington diseases.

Yuji Goto and colleagues had been studying amyloids, dense tangles of protein, to better understand how they form. In an effort to view amyloid formation under a microscope in real-time, they added an amyloid specific dye called thioflavin T (ThT) to the tangles and then hit it with a laser beam to induce fluorescence. Surprisingly, they found that under the right conditions, the laser could actually...read the whole article
