BACKGROUND Fibrosis, which is characterized by the pathological accumulation of collagen, is recognized as an important feature of many chronic diseases, and as such, constitutes an enormous health burden. We need non-invasive specific methods for the early diagnosis and follow-up of fibrosis in various disorders. Collagen targeting molecules are therefore(More)
Hepatocyte growth factor (HGF) is a growth factor for alveolar epithelial cells. Activation of pro-HGF to HGF is regulated by the HGF activator (HGFA), a serine protease, and a specific inhibitor (HGFA inhibitor-1, HAI-1). An imbalance in the HGFA/HAI-1 system might contribute to lung fibrosis. Pro-HGF activation capacity from bronchoalveolar lavage (BAL)(More)
RATIONALE Lung dendritic cells (DCs) have been shown to accumulate in human fibrotic lung disease, but little is known concerning a role for DCs in the pathogenesis of fibrotic lung. OBJECTIVES To characterize lung DCs in an in vivo model of bleomycin-induced pulmonary fibrosis in mice. METHODS We characterized the kinetics and activation of pulmonary(More)
The extracellular matrix (ECM) has long been viewed primarily as an organized network of solid-phase ligands for integrin receptors. During degenerative processes, such as osteoarthritis, the ECM undergoes deterioration, resulting in its remodeling and in the release of some of its components. Matrilin-3 (MATN3) is an almost cartilage specific, pericellular(More)
Chondrocalcin is among the most highly synthesized polypeptides in cartilage. This protein is released from its parent molecule, type II pro-collagen, after secretion by chondrocytes. A participation of extracellular, isolated chondrocalcin in mineralization was proposed more than 25 years ago, but never demonstrated. Here, exogenous chondrocalcin was found(More)
