Stéphane A. Laporte

Biography

Dr. Laporte received his undergraduate degree in Biology (Major Biotechnology), and M.Sc. and Ph.D. degrees in Pharmacology at the Université de Sherbrooke, Quebec, Canada. He trained as a postdoctoral fellow in the group Dr. Marc G. Caron, at Duke University, USA, before joining McGill in 2001.

Research Interest

Our laboratory focuses on understanding the molecular and cellular mechanisms regulating G protein-coupled receptors (GPCRs). We are interested in ligand-directed signaling, and the development of novel molecules with allosteric, biased signaling modes of action, in particular for the prostanglandin PG2α (FP) receptor. Using innovative imaging and biophysical approaches we also study the dynamics of protein complexes involved in receptor trafficking and signaling for different GPCRs, in particular for the angiotensin II type 1 and Bradykinin B2 receptors. Our laboratory is involved in developing novel fluorescently tagged biosensors for studying, in live cells, GPCR signaling and trafficking, with the goal of identifying small molecules regulator of these responses. Our research program aims at providing new insights into the molecular details of GPCR signaling and trafficking, with the goal of identifying new means to improve hormone and drug efficacy, especially in cardiovascular diseases, inflammation, pre-term birth and cancer.
