Congratulations to Graydon (Grey) Gereau, graduate student from the McElligott lab, on his first-author paper exploring neurotensin transmission through the brain-body connection!

The article titled, “Neurotensin and energy balance,” was published in J. of Neurochemistry this week. Sy’Keria Garrison, graduate student in the McElligott lab is co-author and Zoe A. McElligott, PhD, is senior author on the paper.

Abstract

“The neurotensin system spans across the central nervous system, to the enteric nervous system (gut), and the periphery to govern behaviors and physiological responses that tune energy balance to maintain homeostasis. Neurotensin transmission is not only modulated by metabolic signals, neurotensin transmission itself can also impact metabolic state by exerting control over consumption, physical activity, and satiety signals. Many responses to sensory experiences and sleep processes are dictated by neurotensinergic activity via mechanisms that allow the organism to balance energy seeking and utilization to thrive in its environment. Given the broad reach neurotensin signaling has across the homeostatic landscape, understanding this system as a whole and examining new ways to target this system for therapeutic efficacy across many different conditions is necessary.”

A brain labelled CNS over a picture of intestines, labelled Gut + Periphery with a drawing of Neurotensin molecule in between them and curved arrows from the word "Neurotensin" going upward to the brain and downward to the Gut + periphery . There are notations by the brain with arrows indicating a decrease in Feeding, body temp, and Rest, sleep (VTA) and an increase in physical activity and NREM Sleep (LHA CeA PAG). There are notations by the gut + periphery with arrows indicating a decrease in feeding, body temp, physical activity and an increase in fat absorption.
