Insulin lowers blood glucose by promoting its uptake into cells, while glucagon raises it by signaling the liver to release glucose from stored sources. Glucagon is secreted to the blood by alpha ...

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 ...

The research sheds new light on how this enzyme influences glucagon secretion in pancreatic alpha (α) cells, a process crucial for maintaining healthy blood sugar levels. The research ...

The islets chiefly contain beta- and alpha-cells that produce the hormones insulin and glucagon, respectively. Insulin is secreted into the bloodstream and acts much like a key to unlock the body ...

The liver and pancreas are the main actors in glucose metabolism, but not the only ones. Muscles, adipose tissue and the brain play different roles. However, the prize for the best new actor in ...
