Ethanol and LPS are immunomodulators, whose actions are associated with the activation of the transcription factor, NF-kappaB, that mediates the expression of a number of rapid response genes involved in the whole body inflammatory response to injury, including transcriptional regulation of iNOS and COX-2. We investigated modulation by acute ethanol (EtOH) intoxication, LPS and LPS tolerance of...
Liver injury, and frequent consequent fibrosis, is the focus of a number of research groups ranging from molecular biologists to clinicians. It encompasses many aspects and approaches. Among biochemical events the role of Kupffer cells, oxidative stress and pro-inflammatory mediators are eminent. In this review we focus on recent findings into use of natural substances for the modulation of oxi...
Kupffer cells carry on the cell surface a lectin-like receptor with specificity for D-galactose/D-glucose residues. After tryptic digestion of receptors, new lectin activity appears on the plasma membrane within 15 min. Protein biosynthesis de novo is not involved. This indicates the transfer of new lectin molecules stored within the cell to the cell surface. Kupffer cells can enter a physiolog...
This publication summarizes the scientific adventure with Professor Selye, and focuses on the specific effect of rare metal salts on reticuloendothelial functions. Rare earth metal ions markedly affect the functions of cells involved in inflammatory and immunological phenomena. The Kupffer cell blockade induced by GdCl3 is a generally accepted method for investigation of the physiological and p...
Sublethal infection of mice with Listeria monocytogenes was accompanied by an influx of immigrant macrophages into the liver and the generation of substantial H2O2 by isolated liver macrophages. H2O2 production paralleled the course of infection and, after resolution of granulomata, returned to the low levels seen in normal livers. To assess the activation status of Kupffer cells and immigrant ...
BACKGROUND There have been no previous reports how Kupffer cells affect the outcome of living donor liver transplantation (LDLT) with an elderly donor. The aim of this study was to elucidate the influence of Kupffer cells on LDLT. METHODS A total of 161 adult recipients underwent LDLT. The graft survival, prognostic factors for survival, and graft failure after LDLT were examined between case...
Methods and apparatus are described where with living Kupffer cells can be procured from the liver of the rabbit and the dog for study and cultivation in vitro. Almost none of these cells can be dislodged from the normal liver by forcible perfusion; but after they have taken up finely particulate matter (India ink, iron oxide), they come away in great numbers. When they have phagocyted ferromag...
