University of Michigan transporter (VGAT; blue) mRNA expression in the arcuate nucleus of a mouse. MC3R is coexpressed in a high percentage of both AgRP and VGAT neurons in the arcuate nucleus, a brain region that is known to control feeding in both mice and humans.

In a new study scheduled to publish April 21 in Science Translational Medicine, a team of researchers from the University of Michigan and Vanderbilt University pinpoints a protein called melanocortin 3 receptor (or MC3R) as an avenue for accessing the brain circuitry that controls the body’s energy balance and food intake.
