Functionally Separate Populations of Ventromedial Hypothalamic Neurons in Obesity and Diabetes

The Ventromedial hypothalamic nucleus (VMN) maintains healthy metabolic function through several important roles. Collectively, homeostasis is maintained via intermingled cells within the VMN that raise blood glucose, lower blood glucose, and stimulate energy expenditure when needed. This perspective discusses the defining factors for the VMN cell types that govern distinct functions induced by the VMN, particularly in relation to energy balance and blood glucose levels. Special attention is given to distinct features of VMN cells responsible for these processes. Finally, these topics are reviewed in the context of research funded by the Pathway to Stop Diabetes initiative, highlighting key findings and current unresolved questions for future investigations.
