Localized scleroderma is an autoimmune connective tissue disease, where chronic inflammation and abnormal activation of myofibroblasts leads to permanent skin fibrosis. Currently there are no specific therapies targeting fibrosis. In this study, we aimed to find potential new antifibrotic treatments for localized scleroderma, using image-based drug screening assay for fibroblasts isolated from the skin of localized scleroderma patients. We found several drug groups with antifibrotic effects, among them inhibitors of tyrosine kinase, transforming growth factor β receptor, and phosphoinositide-3 kinase, as well as androgen receptor antagonists. Our study suggests new treatment options for localized scleroderma.
