About the Lab
The Xu lab in interested in novel neural circuits, neurotransmitters and intra-neuronal signals that are critical for coordinated control of body weight, feeding behavior, and glucose balance.
We generate unique mouse models, using Cre-loxP/Flp-frt strategy, with genes of interest manipulated in specific populations of neurons at the time of choice. We use these models, in combination of the modern chemogenetics/optogenetics, fiber photometry, electrophysiology and neurotracing approaches, to establish the physiological relevance of specific neural networks in the regulation of energy homeostasis, glucose balance and behaviors.
Our lab is a part of the Children's Nutrition Research Center.
