Abstract
Primary sclerosing cholangitis (PSC) occurs in approximately 25% of patients post-liver transplantation (LT) and is associated with significant morbidity and mortality. Hepatic duct cholestasis following recurrent PSC may lead to the development of liver cirrhosis and the need for liver retransplantation. To date, the exact etiology of the recurrence of PSC post-LT remains unknown, and it is not currently possible to predict which patients are at risk for recurrence of PSC. Extracellular Galectin-3 (Gal-3) acts as a damage-associated molecular pattern (DAMP) when released into the extracellular matrix (ECM) by injured liver cells. Gal-3 plays a crucial role in immune responses and inflammation by binding and cross-linking surface proteins of neutrophils and macrophages, facilitating the chemotaxis of immune cells to the site of injury, and activating the macrophage inflammasome complex. In addition, Gal-3, by activation of hepatic satellite cells (HSC) to myofibroblast phenotype, induces profibrotic molecules, such as transforming growth factor beta (TGF-β) and increases the expression of collagens in the ECM, leading to liver fibrogenesis. According to the evidence, targeting Gal-3 may have important therapeutic potential in preventing the progression of recurrence in PSC and cholestatic progression post-LT.
期刊介绍:
Current Topics in Medicinal Chemistry is a forum for the review of areas of keen and topical interest to medicinal chemists and others in the allied disciplines. Each issue is solely devoted to a specific topic, containing six to nine reviews, which provide the reader a comprehensive survey of that area. A Guest Editor who is an expert in the topic under review, will assemble each issue. The scope of Current Topics in Medicinal Chemistry will cover all areas of medicinal chemistry, including current developments in rational drug design, synthetic chemistry, bioorganic chemistry, high-throughput screening, combinatorial chemistry, compound diversity measurements, drug absorption, drug distribution, metabolism, new and emerging drug targets, natural products, pharmacogenomics, and structure-activity relationships. Medicinal chemistry is a rapidly maturing discipline. The study of how structure and function are related is absolutely essential to understanding the molecular basis of life. Current Topics in Medicinal Chemistry aims to contribute to the growth of scientific knowledge and insight, and facilitate the discovery and development of new therapeutic agents to treat debilitating human disorders. The journal is essential for every medicinal chemist who wishes to be kept informed and up-to-date with the latest and most important advances.
