Description of Research

Melanocortins are known for their central role in skin pigmentation and for their immunomodulatory actions in leukocytes. However, melanocortins appear to have also direct effects on the vasculature and heart. Our current research projects focus on investigating the role of melanocortin signalling in cardiovascular diseases, particularly in atherosclerosis and cardiac hypertrophy. We utilize both loss- and gain-of-function models as well as pharmacological and genetic approaches to advance our understanding of the role of melanocortins and their cognate receptors in these diseases. Ultimately, the research aims at evaluating the therapeutic potential of targeting melanocortin receptors for the management of lipid disorders, atherosclerosis, cardiac hypertrophy.
