Insulin is a hormone that allows glucose in the blood to enter cells, providing them with the energy to function. A lack of adequate insulin plays a key role in the development of diabetes.

It’s known as negative feedback because an increase in hormone decreases the substance being controlled, e.g. an increase in insulin decreases blood glucose concentration.

Insulin resistance occurs when the body’s cells cannot use insulin effectively. Insulin is a hormone that helps the body absorb glucose and balance the blood sugar levels. Insulin resistance ...

Investigating how the production of insulin is regulated in fruit flies reveals surprising insights that may help to better understand how this process unfolds in humans.

Within islets, beta cells secrete insulin, and alpha cells secrete glucagon. Scientists have identified three additional cell types in islets, including cells that secrete the hormones ...

Diabetes is a chronic disease that occurs when the body cannot adequately produce or use insulin, a hormone that facilitates the transportation of glucose from the blood into cells for energy.
