Galanin Receptors

Galanin is widely distributed in the central and peripheral nervous systems and the endocrine system. Three different galanin receptors (GAL_1-3) have been identified which are G_i/o-protein-coupled. They are highly expressed in hypothalamic nuclei and the brainstem. In addition, they are found in proliferating zones of the fetal and adult brain and in peripheral tissues including the pancreas, heart, skin and gastrointestinal tract.

Galanin receptors mediate a variety of physiological functions including inhibition of glucose-induced insulin secretion, stimulation of growth hormone release and modulation of gastrointestinal motility. These receptors also modulate neuronal functions including memory, nociception, spinal reflexes and feeding. Disruption of galanin expression or galanin receptor signaling is seen in many multifactoral conditions, suggesting a role in the development and/or pathology of certain diseases. These include Alzheimer's disease, epilepsy, diabetes, alcoholism, neuropathic pain and cancer.
