AUTOANTIBODIES AND SYSTEMIC SCLEROSIS
Sponsor: IRCCS Ospedale San Raffaele
Summary
Established in vitro assays, combined with state-of-the-art multi-omics approaches and innovative in vitro experimental models, will gain insights into the mechanistic bases underlying Systemic Sclerosis (SS) pathogenesis and will dissect the consequences of treatment with Efgartigimod on functional and phenotypic cell behaviors. Healthy microvascular endothelial cells, fibroblasts and monocytes will be challenged with serum and autoantibodies prior to or upon treatment with Efgartigimod in order to assess both the prevention and the recovery capacity of the FcR blocker. The putative modulatory effect of Efgartigimod on vascular remodeling, endothelial-to-mesenchymal transition, fibroblast-to-myofibroblasts transition and monocyte behavior will be evaluated in in-vitro consolidated assays. Integrated Omics analyses will support and complement the in vitro findings by unveiling potential prognostic signatures and by identifying specific treatment-related profiles that might guide the modulation of the drug usage in order to maximize its beneficial effects.
