Minireview. The hypothalamus and blood glucose regulation.
Complex neural circuits exist in the hypothalamus for the control of metabolic hormones, enzyme activities, and substrate flux that appear to be involved with the normal adaptation to feeding and subsequent blood sugar regulation. Abnormalities within this system have been found in experimental obesity and in human diabetes, and such maladaptive changes are thought to contribute to the pathophysiology of both disorders. The present report is an attempt to present a coherent picture of the manifold factors which may be involved in the homeostatic regulation of blood glucose levels by the hypothalamus. A wide variety of evidence is touched upon here to show that this part of the ancient vertebrate forebrain mediates a neural glucoregulatory mechanism involving the endocrine pancreas, the liver, and the adrenal medulla.
