• Obesity induced the metabolic syndrome, which causes cardiovascular diseases. Obesity has now become a major health concern not only in developed countries but developing countries. However, diet and exercise are still major therapies. We discovered endogenous systems maintaining homeostasis of energy metabolism and revealed several neuronal networks among organs to be responsible for the regulation systems.
• 1) Afferent neuronal signals from adipose tissue regulate appetite and prevent over-eating during obesity development (Cell Metab 2006)
• 2) Neuronal network from the liver enhances basal metabolic rates to prevent obesity development when energy store is increasing (Science 2006) 3) Neuronal network from the liver suppresses adaptive thermogenesis in brown adipose tissue (Cell Metab 2012).

On the basis of these original discoveries, we are aiming at developing new drugs and/or building devices which regulate the inter-organ neuronal networks and hope to conduct collaborative research with a willing company for a practical application to obesity therapy.
