Alzheimers and prion diseases: cellular and genetic mechanisms of neurodegeneration

Alzheimer’s disease and prion diseases like CJD are both fatal brain conditions with no cure, and researchers have spotted a shared flaw in how brain cells handle key proteins in both illnesses. This matters because Alzheimer’s affects a large proportion of the UK’s elderly population, while prion diseases—though rarer—remain a concern due to the unknown number of people infected during the BSE epidemic. Despite decades of research, no treatments stop either disease. The team will study these protein-processing mechanisms in cells, in animals, and in post-mortem brain tissue from Alzheimer’s patients. If this work succeeds, it could reveal how both diseases develop at a fundamental level. That knowledge might eventually point toward new drug targets or early diagnostic markers. This is primarily curiosity-driven fundamental science—there is no immediate clinical application. But similar fundamental research into protein misfolding has already led to breakthroughs in understanding Parkinson’s and Huntington’s diseases. A deeper grasp of these shared cellular processes could, over time, open routes to therapies for millions of people.
