Download or read book Liver Myofibroblasts written by Jiri Kanta and published by Frontiers Media SA. This book was released on 2016-10-25 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Myofibroblasts (MFB) are found in most tissues of the body. They have the matrix-producing functions of fibroblasts and contractile properties that are known from smooth muscle cells. Fundamental work of the last decades has shed remarkable light on their origin, biological functions and role in disease. During hepatic injury, they fulfill manifold functions in connective tissue remodeling and wound healing, but overshooting activity of MFB on the other side induces fibrosis and cirrhosis. The present e-book "Liver myofibroblasts" contains 9 articles providing comprehensive information on "hot topics" of MFB. In our opening editorial we provide a short overview of the origin of MFB and their relevance in extracellular matrix formation which is the hallmark of hepatic fibrosis. Thereafter, leading experts in the field share their current perspectives on special topics of (i) MFB in development and disease, ii) their role in hepatic fibrogenesis, and (iii) promising therapies and targets that are suitable to interfere with hepatic fibrosis.

This book was released on 2020-12-29 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide, liver fibrosis is a major cause of morbidity and mortality and is associated with a high medical and economic burden. It is the common consequence of chronic liver injury due to various etiologies. During fibrogenesis, there is a progressive substitution of the liver parenchyma by scar tissue. Recent advances in the understanding of the history of liver fibrosis have shown that the pathogenesis is driven by different cell types and a large variety of soluble mediators. At present, scientists working in this field aim to increase basic knowledge, improve diagnostics, and try to translate experimental findings into new treatment modalities. This book includes 12 selected contributions from the Special Issue “Cellular and Molecular Mechanisms Underlying the Pathogenesis of Hepatic Fibrosis” that was published in Cells. These articles summarize current perspectives and findings in hepatic fibrosis research showing how scientists try to use basic scientific research to create new therapies and diagnostics.

Download or read book Molecular and Cell Biology of Liver Fibrogenesis written by A.M. Gressner and published by Springer. This book was released on 1992-09-30 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, the proceedings of the International Falk Symposium held in Marburg, Germany, in January 1992, summarizes the most recent advances in the study of cellular and molecular mechanisms of fibrosis provided by contributions from the leading scientists in this field. It updates our knowledge on the basic components of fibrosis, on the cellularorigin and degradation of matrix components, on peptide and non-peptide mediators, cellular cooperation and other mechanisms of fibrogenesis, on the role of the extracellular matrix as modulator of fibrogenesis, and on some aspects of antifibrotic trials and biochemical monitoring of the development of fibrosis. Since liver fibrogenesis has, to a certain extent, attained the status of a model for fibrotic tissue reactions that occur generally in various organs and tissues, the fundamental processes described here may be relevant for other sites of tissue repairs and fibrosis, for would healing and even for atherogenesis.

Available in PDF, EPUB and Kindle. Book excerpt: In the past decade there has been a major sea change in the way disease is diagnosed and investigated due to the advent of high throughput technologies, such as microarrays, lab on a chip, proteomics, genomics, lipomics, metabolomics etc. These advances have enabled the discovery of new and novel markers of disease relating to autoimmune disorders, cancers, endocrine diseases, genetic disorders, sensory damage, intestinal diseases etc. In many instances these developments have gone hand in hand with the discovery of biomarkers elucidated via traditional or conventional methods, such as histopathology or clinical biochemistry. Together with microprocessor-based data analysis, advanced statistics and bioinformatics these markers have been used to identify individuals with active disease or pathology as well as those who are refractory or have distinguishing pathologies. New analytical methods that have been used to identify markers of disease and is suggested that there may be as many as 40 different platforms. Unfortunately techniques and methods have not been readily transferable to other disease states and sometimes diagnosis still relies on single analytes rather than a cohort of markers. There is thus a demand for a comprehensive and focused evidenced-based text and scientific literature that addresses these issues. Hence the formulation of Biomarkers in Disease The series covers a wide number of areas including for example, nutrition, cancer, endocrinology, cardiology, addictions, immunology, birth defects, genetics, and so on. The chapters are written by national or international experts and specialists.
Download or read book Galectin 3 Modulates Liver Fibrogenesis by Facilitating Hepatic Stellate Cell Phagocytosis and Activation in Vitro and in Vivo written by Xiaosong Jiang and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Liver fibrosis is characterized with accumulation of extracellular matrix (ECM) compounds. During fibrogenesis, pathologic stimuli cause hepatocyte apoptosis, and these apoptotic bodies can be cleared by hepatic stellate cells (HSC) by phagocytosis. Upon phagocytosis, HSC, the key fibrogenic cells of the liver become activated and transdifferentiate into myofibroblasts, meanwhile produce extra amount of ECM molecules. Therefore HSC phagocytosis is a major event in the initial process of fibrosis. To study HSC phagocytosis in vivo, we have developed a mouse model, in which a lenti viral-green fluorescence protein expressing vector (LV-GFP) and an adeno viral-tumor necrosis factor-related apoptosis-inducing ligand (Ad-TRAIL) were applied to mice to induce hepatocyte apoptosis and to label the apoptotic bodies. Using this model, observing HSC phagocytosis and activation in vivo has been achieved. Galectin-3 (Gal3), a [beta]-galactoside-binding lectin, is a regulator of the phagocytic process and the expression of Gal3 is related to fibrotic diseases. In this study, we have focused on the mechanism by which Gal3 modulates HSC phagocytosis and activation. We found that HSC from Gal3[superscript -/-] mice displayed decreased phagocytic activity compared to wild type cells, and decreased expression of TGF-[beta] and procollagen [alpha] 1(I). This suppression was partially reversed by recombinant Gal3 suggesting that extracellular Gal3 is required for HSC activation by phagocytosis. HSC expressing wild type integrin [beta]3, but not binding deficient mutant, bind to recombinant Gal3, suggesting that Gal3 mediates HSC phagocytosis via crosslinking to this integrin and facilitating the tethering of apoptotic cells. Blocking integrin [alpha]v[beta]3 resulted in a decrease of HSC phagocytosis. On the other hand, we discovered that Gal3 expression and release were induced in HSC by phagocytosis, via the activation of nuclear factor kappa B (NF-[kappa]B) signaling. The upregulation of Gal3 in active HSC was further confirmed in vivo on the bile-duct ligated animals. Gal3[superscript -/-] mice displayed significantly decreased fibrosis, reduced expression of alpha smooth muscle actin ([alpha]SMA) and procollagen [apha] (I) upon the challenge of bile duct ligation (BDL). Consistently, using the phagocytosis model, we discovered that Gal3[superscript -/-] mice showed less HSC phagocytosis and fibrotic activity following the viral injection. In summary, Gal3 plays a key role in liver fibrosis by mediating HSC phagocytosis and activation in a feed-forward pattern.
