Insulin secretion and the beta cell: the engine of type 2 diabetes
Type 2 diabetes is often described as a disease of insulin resistance, but the beta cell, the pancreatic cell that makes insulin, sits at the center of the story. When the beta cell can no longer compensate for the body's demand, blood sugar rises.
My early genetics work studied ion channels and receptors that shape how the beta cell releases insulin, including variants in CACNA1E and the alpha2A-adrenergic receptor. These are not abstract details. They help explain why some people lose insulin secretion earlier and faster than others.
Understanding the beta cell is how we move from treating a number to treating a mechanism, which is the heart of precision medicine in diabetes.
