“…Alongside the hepatocytes being the parenchymal cells [2], the liver contains nonparenchymal cells (NPCs) such as Liver Sinusoidal Endothelial Cells (LSECs) [3], Hepatic Stellate Cells (HSCs) [4], Kupffer cells [5], Natural Killer cells [6] and different types of immune cells [7,8]. Each different NPC participates to the liver function and hepatotoxic mechanisms by performing important secondary responses upon hepatocyte damage [9].…”

“…In a healthy liver the ECM of the normal perisinusoidal space is made up by a well-balanced and specific quantitative and qualitative amount of collagen type I, III, IV, V and VI, fibronectin, laminin and proteoglycans which has been proven to perform a critical role in maintaining the in vivo phenotype of both hepatocytes and NPCs [12][13][14]. Hepatic stellate cells are located in the perisinusoidal space of Disse, HSCs adhere to the endothelial cells and make contact with the hepatocytes [4,15,16]. Upon liver injury, and especially during chronic liver damage, a dynamic and programmed event occur in which HSCs "transdifferentiate" and become activated by a paracrine stimulation followed by autocrine amplification of the fibrogenic signals [15,17].…”

“…In the past decades, several approaches to isolate HSCs have been used that include; density gradient separation, fluorescent cell sorting and explant culture [4]. The method to separate HSCs from other hepatic cells is based on employing an ex-vivo enzymatic digestion of the liver tissue by collagenases, pronases and DNase allowing for the dissociation of the hepatic cells from the surrounding ECM [32][33][34].…”

“…Freshly isolated HSCs are presented with prominent dendritic cytoplasmic processes and retinoids containing lipid droplets. The cells will gradually display a slightly more myofibroblast phenotype marked by heterogeneous retinoid droplet size during the following days in culture [4,35,36]. Henceforth over several decades, many in vitro investigations have demonstrated the remarkable cell plasticity of HSCs that not only reflects various phenotypes but also mirrors different functions.…”

“…Indeed, it has been demonstrated that the behaviour of HSCs is regulated by a 3D ECM [149][150][151][152]. Freshly isolated HSCs showed changes in cell morphology and cellular functions when comparisons were made between 2D plastic cultures and culturing cells in thick matrigel, 3D type I collagen gel or other substrates [4,151]. Henceforth, many different approaches have provided valid information concerning the co-culture of parenchymal cells with HSCs.…”

Chronic liver disease is a major cause of morbidity and mortality worldwide marked by chronic inflammation and fibrosis/scarring, resulting in end-stage liver disease and its complications. Hepatic stellate cells (HSCs) are a dominant contributor to liver fibrosis by producing excessive extracellular matrix (ECM), irrespective of the underlying disease aetiologies, and for many decades research has focused on the development of a number of anti-fibrotic strategies targeting this cell. Despite major improvements in two-dimensional systems (2D) by using a variety of cell culture models of different complexity, an efficient anti-fibrogenic therapy has yet to be developed. The development of well-defined three-dimensional (3D) in vitro models, which mimic ECM structures as found in vivo, have demonstrated the importance of cell-matrix bio-mechanics, the complex interactions between HSCs and hepatocytes and other non-parenchymal cells, and this to improve and promote liver cell-specific functions. Henceforth, refinement of these 3D in vitro models, which reproduce the liver microenvironment, will lead to new objectives and to a possible new era in the search for antifibrogenic compounds.

If you can submit your illustrations in an electronic form, please submit the original graphic files. Do not insert figures into your Word document. Humana Press prefers that files be submitted in TIFF or EPS format, with at least 300 dpi resolution. PDF, JPG, Excel, and PowerPoint files may also be acceptable. Please check with your editor if you have questions regarding specific figures. Humana Press prefers that art be submitted as electronic files rather than as hard copies; however, scanned images may not be of sufficient quality for reproduction, and authors/editors should expect to submit hard copies of scanned art along with their manuscript. Please scan art at 600 dpi. Remember when considering figures that they will probably be reduced to fit onto a book page, so pay particular attention to making labels highly legible and not too small. You may want to photocopy your figures to the expected final size as a test to determine legibility. The usable page size of the book will usually be about 4.5 x 7.5 inches. Most figures (including their caption) will occupy half a page. Labels should be in a sans-serif font, preferably Helvetica. When at final reduction the size should be no smaller than 8 point. Please ensure that your figures are clearly labeled. Number tables separately.

Purpose of Review This review outlines the current knowledge about hepatic macrophages and provides an overview of therapeutic approaches to target hepatic macrophages for the treatment of liver diseases. Recent Findings In recent years, it has been increasingly recognized that hepatic macrophages (resident macrophages, Kupffer cells, or circulating bone marrow monocyte-derived macrophages) are implicated in liver homeostasis as well as in disease progression and resolution. More recently, different populations of hepatic macrophages with distinct phenotypes and functions have been identified that have shown to play distinct roles in the pathogenesis of various acute and chronic liver diseases. The understanding of the role of hepatic macrophages in initiation, progression, and resolution of liver diseases has given rise to the development of therapeutics that can target different phenotypes of hepatic macrophages. Innovative strategies comprises of microRNA (miRNA), small interfering RNA (siRNA), therapeutic proteins, and small-molecule inhibitors. Summary Evidence from recent in vitro and in vivo studies support the fact that hepatic macrophages can be efficiently targeted using miRNA/siRNA-based approaches, protein-based approaches, and small-molecule inhibitors for the treatment of liver diseases. However, more in-depth understanding underlying the roles of distinct macrophage phenotypes in different liver diseases is required for the translation of novel targeted therapeutics to the clinic. Keywords Hepatic macrophages. Targeted therapeutics. Liver diseases. Monocytes. Kupffer cells This article is part of the Topical Collection on Chronic Liver Disease
