Fibromodulin Interacts with Collagen Cross-linking Sites and Activates Lysyl Oxidase
Sebastian Kalamajski, Dominique Bihan, Arkadiusz Bonna, Kristofer Rubin, Richard W FarndaleFibrosis is characterized by a dense and stiff collagen matrix, formed through a cross-linking process driven by the enzyme lysyl oxidase (LOX). This study investigated the role of another protein, fibromodulin, in this…

Collagen Crosslinking Does Not Dictate Stiffness in a Transgenic Mouse Model of Skeletal Muscle Fibrosis
M A Chapman, R Pichika, R L LieberIn this animal study on mice, researchers investigated why fibrotic, or scarred, skeletal muscle becomes so stiff. While it is known that fibrosis involves an increase in collagen, the amount of collagen alone does not…

Hyaluronan’s Role in Fibrosis: A Pathogenic Factor or a Passive Player?
S Albeiroti, A Soroosh, C A de la MotteThis 2015 review article explores the role of hyaluronan (HA) in fibrosis, a condition where excessive connective tissue buildup impairs organ function. HA is a key component of the extracellular matrix, known for its h…

Painful Connections: Densification Versus Fibrosis of Fascia
P G Pavan, Antonio Stecco, R Stern, Carla SteccoIn this review article, the authors describe two types of fascial changes that can cause pain: densification and fibrosis. Densification is described as a reversible alteration in the viscosity of the loose connective t…

CCN2: a mechanosignaling sensor modulating integrin-dependent connective tissue remodeling in fibroblasts?
Andrew LeaskMechanical tension is essential for the function and health of connective tissue. In skin fibroblasts, the protein integrin β1 plays a key role in adhesion and in regulating healing and fibrosis (scarring). This theoret…

A RHAMM Mimetic Peptide Blocks Hyaluronan Signaling and Reduces Inflammation and Fibrogenesis in Excisional Skin Wounds
Cornelia Tolg, Sara R Hamilton, Ewa Zalinska, Lori McCulloch, Ripal Amin, Natalia Akentieva, Francoise Winnik, Rashmin…In this animal study, researchers investigated how to reduce scarring during skin wound healing. They developed a peptide, P15-1, designed to interfere with signals from fragmented hyaluronan, a molecule involved in inf…

Hyaluronan injection in murine osteoarthritis prevents TGFbeta 1-induced synovial neovascularization and fibrosis and maintains articular cartilage integrity by a CD44-dependent mechanism
Jun Li, Daniel J Gorski, Wendy Anemaet, Jennifer Velasco, Jun Takeuchi, John D Sandy, Anna PlaasIn this mouse study, researchers investigated how hyaluronan (HA) injections might protect joints in osteoarthritis. They found that even though the injected HA was cleared from the knee joint in under two hours, a sing…
