Research interests

The focus of our research at the Centre for Neuroendocrinology is on the neuroendocrine regulation of metabolism. In particular we are interested in the central interaction of the adiposity hormones leptin and insulin, which appears crucial for the maintenance of energy and glucose homeostasis. We established that a loss of central leptin action during obesity leads to impaired insulin action, which might explain the striking correlation of obesity and type 2 diabetes.

We investigate neuroendocrine mechanisms that link obesity, diabetes and Alzheimer's disease.

We focus on manipulating these crucial pathways via nutritive, genetherapeutic and pharmacological approaches to potentially avoid the manifestation of nutrition related diseases.
