Systemic sclerosis (SSc) is an orphan disease characterized by vascular, immune and connective tissue anomalies. Among the many different immune-mediated rheumatic diseases, SSc stands out as a severely incapacitating and life-threatening disease, the pathogenesis of which is largely unknown and for which therapeutic options are few and insufficient. SSc is not inherited in a Mendelian fashion and it is believed that both genetic and environmental factors contribute to disease susceptibility and disease progression.

Our group is from a long time committed to decipher the genetics of SSc through several large multinational candidate gene studies and the recent achievement of a genome-wide association study. Major progresses have been recently achieved and several risk loci have been identified, most of them are involved in autoimmunity. This is a major breakthrough in SSc, switching to a new paradigm of the disease which was until recently considered only as a fibroblast dysfunction condition. However, this also raises new questions such as the precise role of these immune genes on SSc phenotype in comparison to other autoimmune diseases to which they are also often associated. Therefore, there is a clear need to proceed now to their functional validation through a translational approaches. To this end, we aim to delineate the role of SSc-associated genes and to unravel the molecular pathways by which they are implicated in tissue fibrosis with the use of relevant and complementary SSc animal models but also animal models of erosive arthritis to evaluate the role of pleiotropic genes.

Concomitantly, we are performing several clinical research projects in particular in the cardiovascular aspects of rheumatic disorders to try to identify relevant outcomes measures, biomarkers and therapeutic strategies.
