Introductie

Assistant Professor


Biography

Dr. Bruno Guigas is a 41 year-old molecular biologist with a broad expertise in the pathophysiology of metabolic disorders. His scientific path started at the University of Grenoble (France) with a Master’s degree in Exercise Physiology and Bioenergetics, followed by a PhD internship in the group of Prof. X. Leverve where he studied the mechanisms of action of the antidiabetic drug metformin. After graduating, he joined the de Duve Institute (Prof. L. Hue, Brussels, Belgium) where he investigated the role of AMPK in the control of hepatic glucose metabolism and mitochondrial oxidative phosphorylation supported by a “Michel de Visscher” Research Fellowship. Established in The Netherlands for almost a decade with a tenure-track position shared between the departments of Parasitology and Cell and Chemical Biology of the Leiden University Medical Center (LUMC), he’s currently heading a group of ~5 people. During the last years, he has driven several research projects aiming to identify novel therapeutic strategies for obesity and type 2 diabetes, using both in vitro and in vivo approaches in rodent models or humans. He’s also actively involved in several international collaborations on multidisciplinary projects in the field of obesity and type 2 diabetes. More recently, he launched a novel research line within the emerging field of immunometabolism aiming to identify new druggable molecules and/or molecular targets involved in immune-dependent regulation of insulin sensitivity.


Research interest

My main interest is currently focused on studying the molecular mechanisms underlying the immunometabolic effects of parasitic infection and parasite-derived molecules (http://help-t2d.nl/) using both in vitro and in vivo approaches in various rodent models or in humans. This original research line is aimed to identify new metabolically-active molecules and/or potential novel molecular targets involved in tissue-specific regulation of substrate metabolism and insulin sensitivity that can ultimately lead to future therapeutic opportunities for the treatment of metabolic disorders and type 2 diabetes.
