Lee SJ, Jokiaho AJ, Sanchez-Watts G, Watts AG (2018) Catecholaminergic projections into an interconnected forebrain network control the sensitivity of male rats to diet-induced obesity. Am J Physiol Regul Integr Comp Physiol 314(6):R811-R823. doi: 10.1152/ajpregu.00423.2017
Objective: To investigate the role of hindbrain catecholamine neuron pathways and their contribution to long-term energy homeostasis by controlling obesogenic sensitivity to a high-fat, high sucrose choice diet.
Summary: The authors show that catecholamine neurons (primarily in the VLM and NTS) convey essential feedback signals to enable long-term adaptive control of energy metabolism when animals consume a predominantly carbohydrate diet. This is the first report specifically associating this projection system with the long-term control of adiposity.
Usage: Catecholaminergic projections to the PVH and related parts of the forebrain were lesioned with bilateral injections each consisting of 42 ng/200 nL of Anti-DBH-SAP or equimolar amounts of control Mouse IgG-SAP.
