If the concentration of glucose in the blood is too high, insulin is secreted by the pancreas. However, the systemic metabolism must be tightly regulated during an immune response since nutrients may also be exploited by the pathogen and host energy reserves are limited. During the early stages of fasting, hepatic glycogenolysis is a primary energy source.
