SLE is characterized by inflammation and damage to various tissues, complement deficiencies, modification of cytokine secretion and production of autoantibodies. At least 100 different antigens, often nuclear, targeted by specific antibodies have been characterized in SLE. The cause of the illness is poorly understood, multifactorial in essence, depending on risk factors that are genetic, hormonal (with a female prevalence) and environmental. Over the recent years, I have focused my research activity on the pathways involved in autoreactive lymphocytes activation and on molecular events leading to cell death/living phenomena (apoptosis, autophagy) that are central in lupus. Combining my fundamental knowledge of lupus with my long lasting experience in peptide chemistry has enabled me, with my team, to develop very novel strategies to modulate the aberrant immune response and restore normal immune functions using synthetic peptides. The results of a Phase IIb clinical trial directed by ImmuPharma including one of our peptides in ~150 lupus patients gave extremely promising results. This peptide is currently evaluated in a phase III clinical trial both in the US and Europe (LUPUZOR program). More recently, I have been involved in studies dealing with neuropsyschiatric lupus with the objective to better understand the molecular basis of this dramatic form of lupus and propose specific strategies to treat affected patients. My approaches are based on fundamental immunology, immunochemistry, cellular and molecular biology, biochemistry, organic chemistry and pharmacology, structure-function studies, chemoinformatics, physiology, cellular imaging and manipulation of animal models. * Opposite Luxembourg Institute of Health, House of BioHealth, 29, rue Henri Koch L-4354 Esch/Alzette
