Episode Synopsis

In this episode, coauthor Karoline Martins dos Santos discusses the recently published research, "Insulin activates parasympathetic hepatic-related neurons of the paraventricular nucleus of the hypothalamus through mTOR signaling." The study investigates the complex role of insulin in regulating hepatic glucose production, focusing on how insulin influences specific brain regions. While it's known that insulin reduces liver glucose production, the precise mechanisms and brain areas involved have remained unclear. Dr. Martins dos Santos explains how insulin activates parasympathetic hepatic-related neurons in the paraventricular nucleus (PVNhepatic) and how this process relies on mTOR signaling.
