I joined the CHU Research Center and Laval University in 1997 as an independent researcher and assistant professor. I had previously completed 4 years of postdoctoral training in the United States at Columbia University (New York), Baylor College of Medicine (Houston) and Mount-Sinai Hospital (New York). Previously, I obtained a PhD in Immunology from the Pierre & Marie Curie University in 1993 (Paris). Throughout all these years of training, I mainly worked in gene therapy on specific disease applications and in the development of viral vectors.

Epidermolysis Bullosa (EB)

Epidermolysis Bullosa (EB) is a genetic disease that affects about 3/100,000 people (300 to 500 patients in Canada). EB is a hereditary skin disorder that is characterized by skin and/or mucosal detachment in the form of blisters during friction or trauma. Squamous cell carcinomas frequently develop on surfaces prone to skin detachment. There are more than 20 different types of EB, belonging to 4 main groups: simple EB, dystrophic EB, junctional EB and Kindler Syndrome. The severity of the disease ranges from mild to very mutilating, and in some cases the disease can lead to death. EB is an incurable disease, and palliative care is the only solution available to patients.

Recessive dystrophic EB is caused by the mutation of the COL7A1 gene encoding type VII collagen, which forms the necessary structures (anchoring fibrils) for adhesion between the dermis and the epidermis. Gene therapy is a feasible therapeutic approach for patients with recessive dystrophic EB. We are developing an ex vivo gene therapy program for dystrophic EB, the goal of which will be to transplant patients with reconstructed skin in vitro, with corrected keratinocytes and fibroblasts. We are also studying the reversions (“natural gene therapy”) that may appear in certain places in EB patients to be able to cultivate these cells in vitro and to make skin that will then be grafted onto the patient’s diseased parts.
