Graphene Oxide Reduces Toxicity of Alzheimer’s Proteins in Yeast Cell Model

A probable early driver of Alzheimer's disease is the accumulation of molecules called amyloid peptides. These cause cell death, and are commonly found in the brains of Alzheimer’s patients. Researchers at Chalmers University of Technology, Sweden, have now shown that yeast cells that accumulate these misfolded amyloid peptides can recover after being treated with graphene oxide nanoflakes. Their results were published on July 7, 2023 in Advanced Functional Materials. The open-access article is titled “Graphene Oxide Attenuates Toxicity of Amyloid-β Aggregates in Yeast by Promoting Disassembly and Boosting Cellular Stress Response.”
