Target Organs and Primary Actions The liver is unequivocally the primary target for glucagon. Systemic Distribution and Physiological Reach After its processing by the liver, glucagon enters the systemic circulation, allowing it to travel throughout the body.
How Glucagon Travels to the Brain and Regulates Appetite
From the central vasculature, it reaches various tissues, although its effects are largely confined to organs capable of expressing the necessary receptors. This portal system is a critical feature, as it directs the hormone first to the liver via the hepatic portal vein before it reaches the general systemic circulation.
Here, alpha cells produce preproglucagon, which is cleaved to form the active 29-amino-acid hormone. Its presence in the heart suggests a potential role in modulating cardiac function, while its action in the brain indicates involvement in appetite regulation and neuroprotection, areas currently under active investigation.
How Glucagon in the Brain Regulates Appetite and Neuroprotection
In the kidneys, glucagon may influence renal hemodynamics and gluconeogenesis, particularly during states of fasting. The primary answer to where glucagon goes is systemic circulation, but the significance of its destination and the mechanisms governing its travel reveal a complex story of physiological regulation.
