Alpha cells are specialized cells located in the pancreas, specifically in the islets of Langerhans. Their primary function is to produce and secrete the hormone glucagon, which plays a crucial role in regulating blood sugar levels. When blood sugar levels drop, alpha cells release glucagon to stimulate the liver to convert stored glycogen into glucose, thereby increasing blood sugar levels. In addition to their role in glucose metabolism, alpha cells work in conjunction with beta cells, which produce insulin. While alpha cells raise blood sugar levels, beta cells lower them, creating a balance that is essential for maintaining overall metabolic health. This interplay is vital for individuals with conditions like diabetes, where blood sugar regulation is impaired.
