The Citrullinated and MMP-degraded Vimentin Biomarker (VICM) Predicts Early Response to Anti-TNFα Treatment in Crohn's Disease

Background: In Crohn's disease (CD), 10% to 40% of patients do not respond to anti-tumor necrosis factor-α (TNFα) treatment. Currently, there are no biomarkers with adequate sensitivity to separate responders from nonresponders at an early stage.

Aim: The aim of this study was to investigated whe…

Increased Von Willebrand Factor Processing in COPD, Reflecting Lung Epithelium Damage, Is Associated With Emphysema, Exacerbations and Elevated Mortality Risk

Background: Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation and lung tissue deterioration. Given the high vascularity of the lung, von Willebrand factor (VWF), a central component of wound healing initiation, has previously been assessed in COPD. VWF processing,…

End-product of fibrinogen is elevated in emphysematous chronic obstructive pulmonary disease and is predictive of mortality in the ECLIPSE cohort.

Chronic obstructive pulmonary disease (COPD) is characterized by abnormal epithelial repair process that may result in intra-airway accumulation of fibrin. Given that plasma fibrinogen is the only FDA approved biomarker that predicts mortality and COPD exacerbations, we hypothesized tha…

The intestinal tissue homeostasis - the role of extracellular matrix remodeling in inflammatory bowel disease

Introduction: Extracellular matrix (ECM) remodeling of the intestinal tissue is important in inflammatory bowel disease (IBD) due to the extensive mucosal remodeling. There are still gaps in our knowledge as to how ECM remodeling is related to intestinal epithelium homeostasis and healing of the int…

Serological Assessment of the Quality of Wound Healing Processes in Crohn's Disease.

Crohn's disease (CD) is a chronic inflammatory condition characterized by continuous mucosal damage and ongoing wound healing of the intestines. The fibrinolytic system is involved in early parts of the wound healing process. Fibrin is a key mediator of primary blood clot forma…

Specific elastin degradation products are associated with poor outcome in the ECLIPSE COPD cohort

Chronic obstructive pulmonary disease (COPD) is characterized by a slow heterogeneous progression. Therefore, improved biomarkers that can accurately identify patients with the highest likelihood of progression and therefore the ability to benefit from a given treatment, are needed. Elastin is an es…

GPDPLQ1237-A Type II Collagen Neo-Epitope Biomarker of Osteoclast- and Inflammation-Derived Cartilage Degradation in vitro

C-telopeptide of type II collagen (CTX-II) has been shown to be a highly relevant biomarker of cartilage degradation in human rheumatic diseases, if measured in synovial fluid or urine. However, serum or plasma CTX-II have not been demonstrated to have any clinical utility to date. Here, we describe…

Enhanced processing of von Willebrand factor reflects disease severity and discriminates severe portal hypertension in cirrhosis

Portal hypertension in cirrhosis is associated with endothelial dysfunction, impaired wound healing, and decreased platelet count. Increased von Willebrand factor (VWF) formation has been suggested as a compensatory mechanism, but the role of VWF processing has not been directly assesse…

Initiation of the Wound Healing Cascade in Inflammatory Bowel Disease: Assessment of Von Willebrand Factor ADAMTS-13 Processing and Formation in Crohn’s Disease

Background: Crohn’s disease (CD) is a chronic inflammatory condition of the intestinal tract resulting in severe intestinal tissue
damage. The concept of mucosal healing has therefore gained significant interest as a therapeutic end point in the treatment of
inflammatory bowel disease (IBD). Given…

Potential diagnostic value of a type X collagen neo-epitope biomarker for knee osteoarthritis.

Phenotypic changes of chondrocytes toward hypertrophy might be fundamental in the pathogenesis of OA, of which type X collagen (Col10) is a well-known marker. The purpose was to develop a specific immunoassay for blood quantification of a newly identified neo-epitope of type X collagen t…

Lung tissue destruction by proteinase 3 and cathepsin G mediated elastin degradation is elevated in chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is characterized by high levels of protease activity leading to degradation of elastin followed by loss of elasticity of the lung and the development of emphysema. Elastin is an essential structural component of the lung parenchyma to support the expansio…

A fragment of SPARC reflecting increased collagen affinity shows pathological relevance in lung cancer - implications of a new collagen chaperone function of SPARC

The matricellular protein SPARC (secreted proteome acidic and rich in cysteine) is known to bind collagens and regulate fibrillogenesis. Cleavage of SPARC at a single peptide bond, increases the affinity for collagens up to 20-fold. To investigate if this specific cleavage has pathological relevance…

Tumstatin, a Matrikine Derived from Collagen Type IVα3, is Elevated in Serum from Patients with Non-Small Cell Lung Cancer

Fibrosis and cancer are characterized by extracellular matrix (ECM) remodeling. The basement membrane is mainly composed by collagen type IV and laminin. Tumstatin is a matrix metalloproteinase-9 (MMP-9) generated matrikine of collagen type IV α3 chain. We evaluated the potential of tums…

The endothelial specific isoform of type XVIII collagen correlates to annual bleeding rate in haemophilia patients

The medical need in the haemophilic (HF) field to reduce bleeding incidents requires measurement of the annual bleeding rate (ABR) in haemophiliacs. Vascular rupture is associated with damage to the vascular endothelium causing exposure of the basement membrane. Endothelial cells and …

Ulcerative colitis, Crohn's disease, and irritable bowel syndrome have different profiles of extracellular matrix turnover, which also reflects disease activity in Crohn's disease

Increased protease activity is a key pathological feature of inflammatory bowel disease (IBD). However, the differences in extracellular matrix remodelling (ECM) in Crohn's disease (CD) and ulcerative colitis (UC) are not well described. An increased understanding of the inflammatory pr…

Increased basement membrane turnover and strongly attenuated interstitial matrix turnover is a key pathological feature of haemophilia

Altered extracellular matrix (ECM) turnover is a central pathological feature of many diseases. The ECM is a meshwork of molecules that provides structural support to cells throughout the body. It consists mainly of two membranes: the interstitial matrix, which is present between parenchymal cells i…

The good and the bad collagens of fibrosis - Their role in signaling and organ function

Usually the dense extracellular structure in fibrotic tissues is described as extracellular matrix (ECM) or simply as collagen. However, fibrosis is not just fibrosis, which is already exemplified by the variant morphological characteristics of fibrosis due to viral versus cholestatic, autoimmune or…
