Kupffer cells are a critical component of the mononuclear phagocytic system and are central to both the hepatic and systemic kuffer cells to pathogens. Kupffer cells are reemerging as critical mediators of both liver injury and repair.

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. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field.

Aims: Kupffer cells KCs are the liver-resident macrophages and play a leading role in the regulation of liver homeostasis in physiological conditions and in pathology. The study aims to investigate the anti-echinococcosis effect of KCs and the effects of hepatic stellate cells HSCs activation in the progression of liver fibrosis in hepatic alveolar echinococcosis hepatic AE. It is worth noticing that the expression levels of anti-inflammatory cytokines were slightly higher than that of pro-inflammatory cytokines. Conclusions: Our research indicates that KCs have immune-protective effect of anti-echinococcosis and promote liver fiber repair, and it also suggests that they have potential therapeutic value for patients with hepatic AE. Alveolar echinococcosis AE , caused by Echinococcus multilocularis. As most cases involve the liver, patients may suffer from hepatomegaly and recurrent jaundice Menghi et al. Cysts localize first in the liver, and in the early stages, the infection is generally asymptomatic Arrechea Irigoyen et al. As the growth pattern of the cyst is similar to a malignant tumor, the WHO has proposed that a clinical classification that is similar to TNM Tumor, Node, Metastases classification of tumors. Such classification is a necessary tool when making therapeutic decisions for the treatment of this disease Kern et al. AE is a serious life-threatening chronic helminthiasis caused by E.

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.

This disease is characterized by a clinical spectrum ranging from steatosis to hepatocellular carcinoma. Several cell types are involved in ALD progression, including hepatic macrophages. Kupffer cells KCs are the resident macrophages of the liver involved in the progression of ALD by activating pathways that lead to the production of cytokines and chemokines. In addition, KCs are involved in the production of reactive oxygen species. Reactive oxygen species are linked to the induction of oxidative stress and inflammation in the liver. These events are activated by the bacterial endotoxin, lipopolysaccharide, that is released from the gastrointestinal tract through the portal vein to the liver. Lipopolysaccharide is recognized by receptors on KCs that are responsible for triggering several pathways that activate proinflammatory cytokines involved in alcohol-induced liver injury.

These recent advances will likely provide new insights into the potential for therapeutic manipulation of Kupffer cells to promote the resolution of inflammation and enhance wound healing in liver disease. Beyond insulin resistance: Innate immunity in nonalcoholic steatohepatitis. Moreover, KCs express the enzyme heme oxygenase 1 HO-1 in their endoplasmic reticulum and peri-nuclear envelope. The Nod proteins, Nod1 and Nod2, are mainly expressed by antigen-presenting cells and epithelial cells, functioning as cytosolic sensors for innate recognition of microorganisms and regulation of inflammatory responses, as well as for the induction of apoptosis Ding, B. Wynn, T. All organs were then returned to the peritoneal cavity and the peritoneum was closed with 5—0 PDS II violet suture Ethicon. Oxygen-derived free radicals promote hepatic injury in the rat. N Engl J Med. Inzaugarat, M. Caspases can be further classified as proinflammatory or proapoptotic, dependent upon cellular processes. The studies involving human participants were reviewed and approved by Ethical Committee of Xinjiang Medical University.

Origin of Kupffer cells In adult animals, monocytes in the peripheral circulation, originating from precursor cells in the bone marrow, are considered to be immature precursors for tissue macrophages J Gastroenterol Hepatol, 26 , pp. Kupffer Cells in Liver Diseases Overview Kupffer cell activation is essential to the response of the liver to infection or injury; the ensuing inflammatory response protects from infection, as well as limits cellular and organ damage to the host organism Orphanet J.
