An be utilised for the therapy of rheumatoid arthritis. Simply because JAK1 and JAK3 both activate STAT3 this compound may be anticipated to inhibit myofibroblast function. Presently, tofacitinib is under investigation inside a modest doubleblinded phase I/II trial for security and efficacy in SSc. Yet another compound of interest for remedy of fibrosis in SSc is pirfenidone. Pirfenidone is employed for the treatment of idiopathic pulmonary fibrosis and is often a pyridone derivative. Dietary intake of this compound was shown to inhibit bleomycin-induced lung fibrosis in hamsters (191). In addition, this compound reduces fibroblast proliferation and attenuates TGF-induced SMA and collagen production in major skin fibroblast (192, 193). In lung fibroblast of SSc sufferers with interstitial lung illness (ILD), therapy with pirfenidone lowered SMA and fibronectin expression (194). On the other hand, in an open label phase two study with 63 SSc individuals with ILD, no useful effects of pirfenidone had been observed on disease outcomes (187). Nintedanib can be a small molecule kinase inhibitor of platelet derived growth element receptor (PDGFR), vascular endothelial growth element receptor (VEGFR), and fibroblast growth aspect receptor (FGFR), which has been authorized for the therapy of interstitial lung illness, and which can possibly be employed for the remedy of (ILD in) SSc. For this latter application, it was not too long ago granted a quick track designation by the U.S. Meals and Drug Administration (FDA). In lung fibroblasts in vitro, nintedanib inhibits proliferation and motility as induced by FGF and PDGF, but also inhibits TGF-induced collagen deposition (195). In vivo, nintedanib protects mice and rats against bleomycin-induced lung fibrosis (195, 196), and lowers the amount of lymphocytes and neutrophils but not macrophagesFrontiers in Immunology www.frontiersin.orgNovember 2018 Volume 9 Articlevan Caam et al.Unraveling SSc Pathophysiology; The MyofibroblastTABLE 2 Clinical trials performed with putative anti-fibrotic agents in SSc.
