How the liver protein GDF15 affects weight and blood sugar

Novel aspects of Gdf15 biology and function

NIH-funded research University of Pittsburgh at Pittsburgh · NIH-11291794

Finds out whether GDF15 made by liver cells helps improve blood sugar and insulin resistance in adults with obesity-related type 2 diabetes, separate from weight loss.

What this research studies

From a patient's perspective, researchers are working to understand how a protein called GDF15, which the liver makes under stress, might help control blood sugar and insulin resistance in obesity-linked type 2 diabetes. They will use laboratory models, including animal studies and liver cell experiments, to separate effects that come from weight loss from direct effects on glucose metabolism. The team will test whether GDF15 acts through the known brain receptor or through other pathways in the liver and muscle. Results could point to new biological pathways that might be targeted by future treatments.

Who could benefit from this research

Good fit: Adults with obesity-related type 2 diabetes and measurable insulin resistance are the patient group most directly relevant to this work.

Not a fit: People with type 1 diabetes or those whose blood sugar problems are unrelated to obesity-driven insulin resistance are less likely to benefit from these findings.

Why it matters

Potential benefit: If successful, this work could point to new treatments that improve insulin resistance and blood sugar control in type 2 diabetes even without weight loss.

How similar studies have performed: Preclinical animal studies have shown that giving GDF15 can lower body weight and improve glucose control, but clear evidence that it helps glucose metabolism independent of weight loss is limited.
