Andrew Franklin interested in what beta-amyloid is normally doing in the brains of people without Alzheimer's disease. Beta-amyloid is present at low levels in the brain throughout life, and may have an important role in normal brain physiology. Ironically, there is some evidence that beta-amyloid actually facilitates neuronal connectivity and memory in people when it is present at low (normal) concentrations, and becomes toxic to neurons at higher concentrations. By studying its normal function and how it is regulated, we hope to understand better how it may accumulate in the brains of Alzheimer's patients
