Non infectious active uveitis, Soluble-CD95-Ligand
Brief summary
The study aims at defining the role of soluble CD95 Ligand in the physiopathology of the non-infectious uveitis. Soluble CD95 Ligand might have a prognostic interest as well as potential for the discovery of new therapeutic strategies
Detailed description
Non-Infectious active uveitis is a severe inflammatory ocular disease which can expose to the blindness. Actually, the knowledge of the physiopathology of uveitis stay poorly. CD95 Ligand (CD95-L) belongs to a TNF (tumor necrosis factors) receptor family. It knows to play a preponderant role to maintain the eye immune privilege. In particular conditions depending on immunologic environment, CD95-L has pro-inflammatory properties and can interact with Th17 lymphocytes and neutrophils, two cells implicated in non-infectious uveitis. The hypothesis is that s-CD95-L levels might be a prognostic factor in non-infectious uveitis and the study of the molecular mechanisms involved could provide new therapeutic targets. This study will recruit 100 patients with non-infectious uveitis followed in Bordeaux University Hospital. Among classical disease activity information, blood samples will be collected during to assess s-CD95-L. Fundamental research will be realized on patients' sample to evaluate underlying molecular mechanisms. Clinical and biological disease activity, treatment and outcomes will be studied in correlation with s-CD95-L to describe their potential prognostic role. Patients will be followed at regular intervals, accordingly to usual care.
