Should mathematical modeling play a greater role in testing new medical treatment strategies?
On August 20, 2026, Mississippi State University associate professor Shantia Yarahmadian published a new mathematical model in the Bulletin of Mathematical Biology. This model simulates how copper and zinc influence amyloid-beta protein aggregation, a key hallmark of Alzheimer's disease.
Why it matters
The model serves to identify critical mechanisms and generate insights to guide future experimental and therapeutic research. By simulating how chelation and inhibitory therapies affect protein aggregation, it provides a tool for testing potential treatments.
The study utilized mathematical simulations of amyloid-beta aggregation, with results that align with experimental data derived from atomic force microscopy. Researchers analyzed the specific influence of copper and zinc ions on the protein aggregation system.
