Jean-Philippe Girard currently holds a position of Senior Research Director at INSERM and is the Director of the Institute of Pharmacology and Structural Biology (IPBS), a large Research Center from the CNRS and the University of Toulouse (France). He received his Ph.D. in Molecular Biology from the University of Toulouse and did his postdoctoral training in Immunology and Vascular Biology at Harvard Medical School (USA). Jean-Philippe Girard’s research focuses on the role of high endothelial venules (HEVs) and IL-33 cytokine in homeostasis, inflammation and cancer. HEV blood vessels function as portals of entry for lymphocytes into lymphoid organs. A few years ago, he discovered with his team that blood vessels with HEV characteristics are also frequently found in solid tumors, in association with cytotoxic T cell infiltration. Contrary to the dogma that blood vessels facilitate tumor growth, tumor-associated HEVs correlated with favorable clinical outcome in breast cancer. These studies introduced the novel concept that blood vessels in the tumor microenvironment are not all the same and that some types of blood vessels (i.e. tumor-associated HEVs) can contribute to tumor suppression rather than tumor growth. Dr. Girard was awarded several prizes for his work, including the CNRS Silver Medal 2013, “Grand Prix de Cancérologie 2012” from the National Academy of Sciences, “Prix de Cancérologie 2013” from the National Academy of Medecine, and “Prix Scientifique 2016” from ‘Fondation pour la Recherche Médicale’ (FRM).
