Tissue fibrosis can occur after defined events. However, in most cases, no initiating triggers will be identified. These idiopathic fibrotic diseases manifest on a single organ or as systemic diseases. The common and characteristic feature of these diseases is a pathologic activation of fibroblasts with increased release of collagen and other extracellular matrix proteins. The progressive accumulation of extracellular matrix destroys the physiological tissue architecture and impairs the function of the involved organs. Systemic sclerosis (SSc) may serve as a prototypical idiopathic fibrotic disease that affects the skin, lungs, heart, gastrointestinal tract and the kidneys. As in many other fibrotic diseases, failure of the affected organs is common and results in high morbidity and significantly increased mortality. A major reason for the poor prognosis of fibrotic diseases is the lack of effective anti-fibrotic therapies. Current treatment approaches are of limited efficacy
and therapies specifically targeting the aberrant activation of fibroblasts and the release of extracellular matrix are not available for clinical use to date. This necessitates the development of novel targeted therapies to reduce fibrosis and tissue damage.
Orphan nuclear receptors are defined as a group of receptors that can translocate into the nucleus and for which no physiologic ligand has been identified to date. Most of these orphan nuclear receptors function as transcriptional regulators either by direct binding to the promoters of target genes or by modulating the transcriptional activity of other transcription factors. We could demonstrate recently that several orphan nuclear receptors play key-roles in the pathogenesis of fibrotic diseases. By fine-tuning major pro-fibrotic pathways such as TGFβ- and PDGF signalling, nuclear factors are crucial mediators of fibroblast activation in fibrotic diseases. We could also demonstrate that targeting of nuclear receptors might be a promising therapeutic approach in fibrotic diseases.
We now aim to follow these findings and investigate the roles of other orphan nuclear receptors and their coreceptors. We will characterize the molecular mechanisms, by which these nuclear receptors regulate fibroblast activation in vitro and evaluate their potential as novel therapeutic targets in different mouse models.
