    Team: Pathogenesis and innovative therapies in systemic sclerosis and chronic fibro-inflammatory diseases





    Systemic sclerosis (SSc), a multisystem autoimmune connective tissue disease, has the highest mortality from all inflammatory rheumatological disorders and a heavy morbidity. Its pathogenesis is incompletely understood but it is thought to occur because of interactions between susceptibility genes and environmental factors. The interplay between microvascular damages and both innate and adaptative immune disturbances promotes activation of mesenchymal cells that induce fibrosis. Our group is committed to decipher SSc pathogenesis since many years. Our strategies include genetic susceptibility, polarization of innate and adaptative immune responses, role of reactive oxygen species in the interplay between various systems, epigenetic marks contributing to fibroblast dysfunction and chronic inflammation,  with the ultimate goal to develop biomarkers and new therapies. We have established a huge databank of DNA, mRNA, serum, plasma, tissues and cells to perform translational research.  Moreover, we have established a pre-clinical platform of SSc related and complementary animal models to investigate in vivo any relevant candidate as a potential treatment. These strategies are further applied in other fibro-inflammatory diseases with key interest in rheumatoid arthritis and endometriosis thanks to the expertise and recruitment at Cochin University Hospital.
