Immune function of nonparenchymal liver cells

Immune function of nonparenchymal liver cells.

The liver is the human body largest digestive and metabolic organ, and a very important immune organ. This paper discusses the location and morphology of hepatic sinusoidal endothelial cells, dendritic cells, hepatic stellate cells, and Kupffer cells in the liver and their role in regulating immune functions. Therefore, here we provide a preliminary understanding of the immune regulatory functi...

Biosynthesis and degradation of hyaluronan by nonparenchymal liver cells during liver regeneration.

Hepatic stellate cells (HSC) and endothelial cells of the liver sinusoids synthesize and degrade hyaluronan, respectively. The roles of these cell types in the biosynthesis and degradation of hyaluronan were studied during regeneration following partial hepatectomy. Pure cultures of HSC and liver endothelial cells (LEC) were obtained from regenerating liver at different stages using a Nycodenz ...

Hepatitis B virus suppresses toll-like receptor-mediated innate immune responses in murine parenchymal and nonparenchymal liver cells.

UNLABELLED We have previously shown that Toll-like receptor (TLR)-activated murine nonparenchymal liver cells [(NPC); Kupffer cells (KC), liver sinusoidal endothelial cells (LSEC)] can suppress hepatitis B virus (HBV) replication. Therefore, the aim of this study was to investigate whether HBV has the ability to counteract the TLR-mediated control of its replication. Freshly purified murine hep...

Mouse liver transplantation tolerance: the role of hepatocytes and nonparenchymal cells.

Effects of methanolic extracts of Epilobium parviflorum on growth and function of human liver cells HepG2

Introduction: Epilobium parviflorum, the willow-herb, extracts contain strong antioxidant compounds and inhibit few types of cancer cell. This study investigates for the first time the effect of its extracts on the growth of human liver cells HepG2, also under oxidative stress. Materials and Methods: Methanolic extract of roots, shoots and flowers was prepared separately. Cell viability was ass...
