AbstractBody homeostasis is predominantly controlled by hormones secreted by endocrine organs. The central nervous system contains several important endocrine structures, including the hypothalamic-pituitary axis. Conventionally, neurohormones released by the hypothalamus and the pituitary gland (hypophysis) have received much attention owing to the unique functions of the end hormones released by their target peripheral organs (e.g., glucocorticoids released by the adrenal glands). Recent advances in mouse genetics have revealed several important metabolic functions of hypothalamic neurohormone-expressing cells, many of which are not readily explained by the action of the corresponding classical downstream hormones. Notably, the newly identified functions are better explained by the action of conventional neurotransmitters (e.g., glutamate and GABA) that constitute a neuronal circuit. In this review, we discuss the regulation of appetite and metabolism by hypothalamic neurohormone-expressing cells, with a focus on the distinct contributions of neurohormones and neurotransmitters released by these neurons.

Abstract. The development of epinephrine, norephinephrine, and total catecholamine secretion in plasma and andrenal glands was studied in newborn rats at short intervals: at day 2, 4, 6, 8, 10, 12 and 23. The increase in the plasma level of epinephrine represents a maturation of the secretion of the adrenal medulla. The increase in plasma of epinephrine and norepinephrine and the content of catecholamines in the adrenal glands of both normal animals and those treated with either high doses of T4 or cortisol at birth suggest a slowing down of the normal development of epinephrine secretion. This was confirmed by inducing hypoglycemia in these three groups of animals by a 20-h fast or by insulin administration (0.1436 μmol/kg). We conclude that both high doses of T4 and cortisol administered at birth seem to retard the development of the autonomic nervous system similar to the effect on the central nervous system.

Insect Central Nervous System

A simple preparation designed to screen and compare the central action of putative neuroactive agents in the moth Manduca sexta is described. This approach combines microinjections into the central nervous system with myograms recorded from a pair of spontaneously active mesothoracic muscles. Pressure injection of either octopamine or Manduca adipokinetic hormone (M-AKH) into the mesothoracic neuropile increases the monitored motor activity. Under the conditions used, the excitatory effects of M-AKH exceed those of the potent neuromodulator octopamine. This suggests that M-AKH plays a role in the central nervous system in addition to its known metabolic functions and supports recent evidence that neuropeptides in insects can be multifunctional.

Fetal lambs were treated with a single dose of anti-mouse nerve growth factor (anti-NGF) at 80 days gestational age. The catecholamine content of tissues was determined at 135 days gestational age. There was a reduction of either norepinephrine, epinephrine, or both, in the thymus, thyroid, atrium (but not ventricle), lung, liver, kidney, and jejunum when compared with age-matched control fetuses. The spleen, ileum, colon, and the adrenal glands were not affected by anti-NGF. In treated fetuses there was a reduction in catecholamine content of the thalamus, hypothalamus, hippocampus, medulla, cerebellum, and cervical spinal cord. These results show that some tissues are sensitive to, and some are refractory to, the action of anti-NGF at 80 days gestation. Also the results suggest that NGF may play a role in the development of catecholamine-containing neurons within the central nervous system.

Abstract Central nervous system, mainly the hypothalamus and the brainstem are importantkeys in glucose homeostasis. Not only do they use glucose as primary fuel for theirfunctioning but they are part of intricate neuronal circuits involved in glucose uptakeand production as was first shown by Claude Bernard. Moreoverelectrophysiological analysis of hypothalamus revealed the existence of glucosensingneurons whose firing rates are controlled by glucose extracellular level. Furtherinformation was obtained regarding the importance of leptin, insulin and free fattyacids as afferent signals received by these neural structures. As for the main efferentpathways, autonomic system is the one connecting CNS with the effector organs (theliver, the pancreas and the adrenal glands).

The Central Nervous System

Neuroblastoma is a malignant tumor that develops from the stem cells of the sympathetic ganglia and the adrenal medulla and belongs to the group of neuroendocrine tumors. It is most often localized in the adrenal glands and the retroperitoneal space, less – in sympathetic ganglia of the neck and thoracic cavity. Pain syn-drome is one of the leading manifestations in patients with disease progression. Unlike other patients, a pain syndrome in oncological patients is not a temporary or periodic sensation, it has no physio-logical expediency, it does not have a protective mechanism, but, on the contrary, pain in this group of patients leads to inadaptation, distorted perception of pain and small impulses, most importantly, accompanied by various disorders of the functions of the central nervous system in the patient’s body.

Interleukin-1 (IL-1) is a cytokine that mediates the acute phase reaction. Many of the actions of IL-1 involve direct effects on the central nervous system. However, IL-1 has not previously been identified as an intrinsic component within the brain, except in glial cells. An antiserum directed against human IL-1 beta was used to stain the human brain immunohistochemically for IL-1 beta-like immunoreactive neural elements. IL-1 beta-immunoreactive fibers were found innervating the key endocrine and autonomic cell groups that control the central components of the acute phase reaction. These results indicate that IL-1 may be an intrinsic neuromodulator in central nervous system pathways that mediate various metabolic functions of the acute phase reaction, including the body temperature changes that produce the febrile response.
