High-mobility group box 1 (HMGB1) acts as an early mediator of inflammation and organ damage in hepatic ischemia-reperfusion (I/R) injury. Glycyrrhizin is a natural anti-inflammatory and antiviral triterpene in clinical use. The purpose of this study was to investigate the effect of glycyrrhizin on liver injury caused by I/R and production of HMGB1 by Kupffer cells in rats. In the first test pe...

The fine structural characteristics and phagocytic properties of peroxidase-positive and peroxidase-negative cells in rat hepatic sinusoids were investigated. Cells with a positive peroxidase reaction in the endoplasmic reticulum and the nuclear envelope make up approximately 40% of cells in rat hepatic sinusoids and have abundant cytoplasm containing numerous granules and vacuoles, and occasio...

There have been numerous reports that chemicals which induce peroxisomes in rodent liver increase DNA synthesis in isolated hepatic parenchymal cells, but not as well in vitro as in vivo. It is also known that tumour necrosis factor alpha (TNFalpha) is mitogenic in isolated hepatocytes. Since Kupffer cells are a major source of TNFalpha in the liver and have recently been shown to be activated ...

Sinus histiocytosis massive lymphadenopathy (SHML) syndrome with hepatic involvement, occurring in a seven-year-old black female, is reported. Morphologic characterization of the hepatic lesion is accomplished utilizing conventional light, fluorescent and electron microscopy, and histochemical techniques and by comparing and contrasting the findings with those in cases of familial erythrophagoc...

We examined whether the macrophages in the liver, Kupffer cells, could be activated to a tumoricidal state in a similar way as has been described for other macrophage types. Kupffer cells were isolated by centrifugal elutriation of pronase-treated rat livers. Incubation with highly purified recombinant rat 7-interferon in combination with small amounts of lipopolysaccharide or muramyldipeptide ...

She, Hongyun, Shigang Xiong, Min Lin, Ebrahim Zandi, Cecilia Giulivi, and Hidekazu Tsukamoto. Iron activates NFB in Kupffer cells. Am J Physiol Gastrointest Liver Physiol 283: G719–G726, 2002; 10.1152/ajpgi.00108. 2002.— Iron exacerbates various types of liver injury in which nuclear factor (NF)B-driven genes are implicated. This study tested a hypothesis that iron directly elicits the signalin...

This study determined whether free radical formation by the liver, tumor necrosis factor (TNF)-alpha production by isolated Kupffer cells, and plasma endotoxin are affected by dietary saturated fat. Rats were fed enteral ethanol and corn oil (E-CO) or medium-chain triglycerides (E-MCT) and control rats received corn oil (C-CO) or medium-chain triglycerides (C-MCT) for 2 wk. E-CO rats developed ...

Cirrhosis is the final outcome of liver fibrosis. Kupffer cell-mediated hepatic inflammation is considered to aggravate liver injury and fibrosis. Alternatively-activated macrophages are able to control chronic inflammatory events and trigger wound healing processes. Nevertheless, the role of alternative Kupffer cell activation in liver harm is largely unclear. Thus, we evaluated the participat...
