In addition, they showed that the hormone leptin is involved in the increase of blood vessels in the hypothalamus of obese mice, contributing of hypertension. Helmholtz Zentrum München led the study and collaborated with Ludwig-Maximilians-Universität München, the Technical University of Munich and the German Diabetes Center.
