Collagen biology and non‐invasive biomarkers of liver fibrosis
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 liver disease (NAFLD). In particular, there is a need for diagnostic and prognostic tools, as well as predictive biomarkers that reflect the efficacy of interventions, as described by the BEST criteria (Biomarkers, EndpointS, and other Tools Resource). This review covers the various liver collagens, their functional role in tissue homeostasis and delineates the common nomenclature for biomarkers bas…
Is the Total Amount as Important as Localization and Type of Collagen in Liver Fibrosis Attributable to Steatohepatitis?
Is liver fibrosis just liver fibrosis? Or do the subtype of collagen, its spatial localization in the liver, its cell of origin, and the time point at which it is synthesized also matter? It is important, since the various collagen subtypes hold different informative values regarding reparative processes in the liver, and as collagens have also emerged as important signaling molecules (1). Novel data have challenged our perception of liver fibrosis and collagens, which may have important implications regarding the development of new biomarkers and anti-fibrotic interventions. The traditional histological analysis of liver biopsies using histochemical collagen stains, such as the Masson's Tr…
