Background: Liver fibrosis accumulation is considered a turnover disease, with formation exceeding degradation, although this hypothesis has never been tested in humans. Aims: To investigate extracellular matrix (ECM) remodelling in a biopsy-controlled study of alcohol-related liver disease (ALD) p...

The effect of direct-acting antiviral (DAA) therapy on extracellular matrix (ECM) turnover, a prominent feature of chronic hepatitis C (CHC), is unknown. ECM protein degradation and formation generate fragments reflecting the tissue turnover balance when quantified in the blood. PRO-C3 and PRO-C4 re...

There is an unmet need for high-quality liquid biomarkers that can safely and reproducibly predict the stage of fibrosis and the outcomes of chronic liver disease (CLD). The requirement for such markers has intensified because of the high global prevalence of diseases such as non-alcoholic fatty liv...

Following liver transplantation (LT), 10-30% of patients develop recurrent cirrhosis (RC). There is an urgent need for predictive non-invasive markers for improved monitoring of these patients. Here we studied extracellular matrix biomarkers as predictors of RC after LT. Forty-seven LT patients were...

N-terminal propeptide of type II collagen (PIINP) is a biomarker reflecting cartilage formation. PIINP exists in two main splice variants termed as type IIA and type IIB collagen NH₂-propeptide (PIIANP, PIIBNP). PIIANP has been widely recognized as a cartilage formation biomarker. However, the utili...

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...

BACKGROUND AND AIMS: Macrophages play a significant role in chronic liver disease as reflected by elevated soluble (s)CD163 and mannose receptor (sMR) levels and associated with liver disease severity and prognosis. Extracellular matrix remodelling associated with fibrogenesis may be affected by sys...

OBJECTIVES: The expanding spectrum of targeted therapies for rheumatoid arthritis (RA) implies a need for development of precision tools for disease assessment reflecting pathobiologic processes. Type IV collagen is an abundant protein of basement membranes, but is also present in the intercellular ...

OBJECTIVES: The objective of this study was to examine the tissue degradation in response to anti-IL6 receptor treatment in rheumatoid arthritis (RA) patients which are anti-TNF-α inadequate responders. METHODS: RADIATE was a randomised, double-blinded, placebo-controlled, parallel-group, phase III...

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...

Objectives: To investigate the turnover of type I and III collagen by neo-epitope markers in patients with axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). Methods: Patients with PsA (n=101) or axSpA (n=110) and healthy subjects (n=120) were included. Demographic and clinical data wer...

Altered architecture, composition and quality of the extracellular matrix (ECM) are pathological hallmarks of several inflammatory and fibro-proliferative pathological processes such as osteoarthritis (OA), rheumatoid arthritis (RA), fibrosis and cancer. One of the most important components of the E...

BACKGROUND: Psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA) are chronic inflammatory rheumatic diseases with complex origins. Both are characterized by altered extracellular matrix remodeling in joints and entheses that results in destructive and osteochondral proliferative lesions. Th...

OBJECTIVE: Tissue destruction in rheumatoid arthritis (RA) is predominantly mediated by matrix metalloproteinases (MMPs), thereby generating protein fragments. Previous studies have revealed that these fragments include MMP-mediated collagen type I, II, and III degradation, citrullinated and MMP-deg...

Objective: Citrullination has become a hot topic within recent years due to its involvement in diseases such as rheumatoid arthritis (RA), multiple sclerosis and fibrosis. Citrullinations are the conversion of arginine to citrulline by peptidylarginine deiminase (PAD) enzymes, which affect protein p...

Infantile malignant osteopetrosis (IMO) is a rare, lethal, autosomal recessive disorder characterized by non-functional osteoclasts. More than 50% of the patients have mutations in the TCIRG1 gene, encoding for a subunit of the osteoclast proton pump. The aim of this study was to restore the resorpt...
