Abstract
Growth hormone (GH) is secreted by somatotropic cells of the anterior pituitary gland. The classical effects of GH comprise the stimulation of cell proliferation, tissue and body growth, lipolysis, and insulin resistance. The GH receptor (GHR) is expressed in numerous brain regions. Notably, a growing body of evidence indicates that GH-induced GHR signaling in specific neuronal populations regulates multiple physiological functions, including energy balance, glucose homeostasis, stress response, behavior, and several neurological/cognitive aspects. The importance of central GHR signaling is particularly evident when the organism is under metabolic stress, such as pregnancy, chronic food deprivation, hypoglycemia, and prolonged exercise. These particular situations are associated with elevated GH secretion. Thus, central GH action represents an internal signal that coordinates metabolic, neurological, neuroendocrine, and behavioral adaptations that are evolutionarily advantageous to increase the chances of survival. This review summarizes and discusses recent findings indicating that the brain is an important target of GH, and GHR signaling in different neuronal populations regulates essential physiological functions.
期刊介绍:
Reviews in Endocrine and Metabolic Disorders is an international journal dedicated to the field of endocrinology and metabolism. It aims to provide the latest advancements in this rapidly advancing field to students, clinicians, and researchers. Unlike other journals, each quarterly issue of this review journal focuses on a specific topic and features ten to twelve articles written by world leaders in the field. These articles provide brief overviews of the latest developments, offering insights into both the basic aspects of the disease and its clinical implications. This format allows individuals in all areas of the field, including students, academic clinicians, and practicing clinicians, to understand the disease process and apply their knowledge to their specific areas of interest. The journal also includes selected readings and other essential references to encourage further in-depth exploration of specific topics.
