A hepatocyte is a cell of the main parenchymal tissue of the liver. Hepatocytes make up 80% of the liver's mass. Hepatocytes make up 80% of the liver's mass. These cells are involved in:
Liver cytology is the branch of cytology that studies the liver cells and its functions. The liver is a vital organ, in charge of almost all the body’s metabolism. Main liver cells are hepatocytes, Kupffer cells, and hepatic stellate cells; each one with a specific function.
Space (·) each pressing of the space key will be displayed like this. Non-breaking space (°) is a space character that prevents an automatic line break at its position. Pilcrow (¶) is the symbolic representation of paragraphs. Line break (↵) breaks the current line without new paragraph. It puts lines of text close together.
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. [2] [3] They form part of the mononuclear phagocyte system.
Nitro blue tetrazolium is used in a diagnostic test, in particular, for chronic granulomatous disease, a disease in which there is a defect in NADPH oxidase; therefore, the phagocyte is unable to make the reactive oxygen species or radicals required for bacterial killing, resulting in bacteria thriving within the phagocyte. The higher the blue ...
A cell that performs phagocytosis is called a phagocyte. The engulfing of a pathogen by a phagocyte. In a multicellular organism's immune system, phagocytosis is a major mechanism used to remove pathogens and cell debris. The ingested material is then digested in the phagosome.
The LSECs contain 45% and 17% of the liver's total mass of pinocytic vesicles and lysosomes, and contain twice as many clathrin-coated pits per membrane unit, compared with two other major liver cells, Kupffer cells and hepatocytes, [5] reflecting the high capacity clathrin-mediated endocytic activity of LSECs.
Philippe Gripon later developed these cells, finding that they had the ability to undergo complete hepatocyte differentiation while retaining all liver-specific functions. As a way to honor the contributions of Rumin and Gripon, the cells were named HepaRG, using the first letter of their last names.
