Diabetes Mathematical Models
Diabetes mathematical models from our lab are listed below. The models illustrate how diabetes results from the interaction of insulin resistance and impairment of the ability of beta-cells to compensate for it.
This model for the pathogenesis of type 2 diabetes shows that disease onset is a threshold-crossing process, which explains why prevention is easier than cure. One of the predictions of the model is confirmed in the companion experimental paper.

This model accounts for the diversity of pathways typically followed, focusing on two extreme alternatives, one that goes through impaired fasting glucose (IFG) first and one that goes through impaired glucose tolerance (IGT) first. IFG generally results from primarily hepatic insulin resistance, while IGT results primarily from peripheral insulin resistance. We consider whether hyperinsulinemia may be a cause of insulin resistance rather than a consequence and find that this is at best a small effect.
