Stiff and tight skin: a rear window into fibrosis without inflammation.

Abstract

In this issue of Science Translational Medicine, a report by Loeys et al. on mutations in the fibrillin-1 gene in patients with skin fibrosis (stiff skin) adds a new piece of information on a connective tissue disorder that resembles systemic sclerosis, an autoimmune disease characterized by skin fibrosis and visceral organ involvement. Here, we discuss the implications of these findings, as well as new opportunities for targeted therapy for fibrosis.
