| Outline of Final Research Achievements |
We examined the role of the ventromedial hypothalamic (VMH) neuron in the control of metabolism in mice by using Hyperinsulinemic-euglycemic clamp and 2DG method. We also examined the effect of preferential activation of Ad4BP neuron in the VMH on food intake and metabolism. Leptin increased glucose uptake in muscle and inhibited glucose production in the liver by enhancing insulin sensitivity. Activation of Ad4BP neuron in the VMH by DREADD inhibited food intake and increased insulin sensitivity in skeletal muscle and the liver. These results thus suggested that VMH neurons play an important role in insulin sensitivity in skeletal muscle and the liver as well as food intake.
