What is a liver star cell?

The liver star cell is generally located in the liver and is usually in the shape of a spindle. The core is usually prolonged or has an oval shape, while scientists believe that projections similar to the spine can detect chemical signals and pass them to the inside of the cell. Also called perisinusoidal cells, liver starfish usually localized between sinusoids and hepatocytes. They normally store vitamin A and can help transport different proteins, including immune messengers called cytokines. Often there is a strong response to liver damage, as these cells can help create scars in the liver.

are usually in the liver star cells of fat droplets, which are stored by vitamin A. The cell may also represent lipid antigens in the liver that can help stimulate the immune system. In addition to being fat storage cells and regulating some immune functions, liver starfish sometimes release proteins that can stimulate liver regeneration after a transplacent. Research studies have shown that cellularSignaling with these cells helps to repair the liver even after injury.

While it is vital to the liver function, the liver star cell is usually in a sleeping or resting state until it is activated in response to liver damage. When the liver is injured or sick, the cell tends to multiply; His ability to close is also prevalent. Other changes usually include reduced ability to store vitamin A, greater sensitivity and response to certain chemicals and collagen secretion such as scars tissue, often the cause of cirrhosis.

variety found in the liver is similar to pancreatic star cell, except for the liver type is usually less susceptible to damage to oxygen deficiency if the blood flow from the arteries is reduced. Most of the liver blood supply comes from veins, and this characteristic for cells, along with other processes, can contribute to how the liver can regenerate. A hepatic star cell canAlso cause inflammatory reactions and often include receptors for common proteins that can affect them.

Even after damage, liver cells can return to rest or damaged buildings may die, which often occurs in the regression of diseases such as liver fibrosis. Stellate cells in the liver are sometimes called ito cells, after a Japanese doctor who studied them in the 20th century. Similar cells that store vitamin A and resemble a liver star cell can also be found in the kidneys, lungs and intestines.
