Kupffer cells , also known as stellate macrophages and Kupffer—Browicz cells , are specialized cells localized in the liver within the lumen of the liver sinusoids and are adhesive to their endothelial cells which make up the blood vessel walls. Kupffer cells comprise the largest population of tissue-resident macrophages in the body. Gut bacteria, bacterial endotoxins, and microbial debris transported to the liver from the gastrointestinal tract via the portal vein will first come in contact with Kupffer cells, the first immune cells in the liver. It is because of this that any change to Kupffer cell functions can be connected to various liver diseases such as alcoholic liver disease, viral hepatitis, intrahepatic cholestasis, steatohepatitis, activation or rejection of the liver during liver transplantation and liver fibrosis. Kupffer cells can be found attached to sinusoidal endothelial cells in both the centrilobular and periportal regions of the hepatic lobules. Kupffer cell function and structures are specialized depending on their location. Periportal Kupffer cells tend to be larger and have more lysosomal enzyme and phagocytic activity, whereas centrilobular Kupffer cells create more superoxide radical.

Although macrophages contribute to cancer cell dissemination, immune evasion, and metastatic outgrowth, they have also been reported to coordinate tumor-specific immune responses. We therefore hypothesized that macrophage polarization could be modulated therapeutically to prevent metastasis. These findings demonstrate the significance of macrophage function in metastasis and identify Kupffer cells as a potential therapeutic target against pancreatic cancer metastasis to the liver. Marcelo M. Metastasis is among the leading causes of cancer-associated deaths 1. Metastatic lesions form from tumor cells that disseminate from a primary tumor and seed a distant tissue, such as the liver 2. During this process, disseminated tumor cells DTCs must evade elimination by local immune cells and adapt to a new microenvironment.

For overall survival studies, mice kuffer cells up to seven doses of BG. Annotated upregulated orange and downregulated blue genes after BG are highlighted.

AoH publishes editorials, opinions, concise reviews, original articles, brief reports, letters to the editor, news from affiliated associations, clinical practice guidelines and summaries of congresses in the field of Hepatology. Our journal seeks to publish articles on basic clinical care and translational research focused on preventing rather than treating the complications of end-stage liver disease. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact.

Thurman RG. Reporting summary Further information on research design is available in the Nature Portfolio Reporting Summary linked to this article. Res 2 , 94— Low TLR4 expression by liver dendritic cells correlates with reduced capacity to activate allogeneic T cells in response to endotoxin. In contrast, results from other studies seemed to associate alternative M2 macrophages to the resolution of fibrosis by phagocytizing apoptotic cells and matrix components via mannose and scavenger receptors [ 45 ]. Efferocytosis reprograms the tumor microenvironment to promote pancreatic cancer liver metastasis Article Open access 14 February Nonparenchymal cells and hepatotoxicity. Other complement receptors are found on the KC surface, such as anaphylatoxin C3a receptor, C5a receptor [ 63 , 64 ] and complement receptors 1 and 4 [ 65 ]. Ofek I, Sharon N. As a result, Kupffer cells infrequently contact cancer cells during metastasis.

Briefly, the abdomen was shaved and sterilized, and depth of anesthesia was assessed prior to performing a median laparotomy. Activated macrophages promote hepatitis C virus entry in a tumor necrosis factor-dependent manner. For overall survival studies, mice received up to seven doses of BG. The origin of the synergistic effect of muramyl dipeptide with endotoxin and peptidoglycan. However, anti-metastatic activity was dependent not only on Kupffer cells but also T cells.

The close proximity of Kupffer cells to parenchymal and nonparenchymal cells within the liver supports the ability of Kupffer cells to regulate hepatic function, both in health and disease. Evidence that chronic alcohol exposure promotes intestinal oxidative stress, intestinal hyperpermeability and endotoxemia prior to development of alcoholic steatohepatitis in rats. Long, K. Pradere, J. Cancer Biol Ther. Granger DN. Both male and female mice between 8 to 12 weeks of age were used, except for overall survival and scRNAseq studies where only female mice were used. Role of hepatic resident and infiltrating macrophages in liver repair after acute injury.
