PVN Neurons in Estradiol Treated Middle-Aged Mice

In this episode of the APS Publications Podcast, featuring an article from AJP–Regulatory, Integrative and Comparative Physiology, authors Andrea Zsombok, Lucie Desmoulins, and Adrien Molinas discuss the role of estradiol treatment in regulating metabolism and glucose homeostasis. In their study with middle-aged, high-fat diet-fed, ovariectomized female mice, the authors found that liver-related neurons in the hypothalamus became more excitable. Estradiol treatment reduced this excitability, suggesting that midlife estradiol therapy may support healthier brain-liver metabolic regulation.
