kupffer's cell
Noun: A specialized, fixed macrophage (a type of white blood cell) located in the lining of the liver sinusoids (small blood vessels). Its primary function is to phagocytose (engulf and destroy) bacteria, foreign proteins, worn-out red blood cells, and other particulate debris from the blood as it flows through the liver.
The term "Kupffer's cell" is used specifically in the fields of anatomy, histology, physiology, and medicine to describe this unique liver cell. It is always used as a noun. * The Kupffer's cell is an essential component of the mononuclear phagocyte system. * Kupffer's cells play a crucial role in cleansing the blood that comes from the intestines.
- Under the microscope, the scientist identified the star-shaped Kupffer's cells adhering to the walls of the sinusoid.
- One of the key functions of a Kupffer's cell is to remove old erythrocytes from circulation.
- Liver inflammation can involve the activation of numerous Kupffer's cells.
- Activation of Kupffer's cells: Refers to the process where these cells become stimulated, often in response to infection or toxins, leading to the release of inflammatory signals (cytokines).
- The research focused on the activation of Kupffer's cells following a high-fat diet.
- Kupffer cell hyperplasia: A medical term describing an increase in the number of Kupffer's cells, often seen in response to chronic liver injury.
- The biopsy showed evidence of Kupffer cell hyperplasia.
- Kupffer cell: A common variant spelling that omits the possessive 's'. Both "Kupffer's cell" and "Kupffer cell" are accepted in scientific literature.
- Hepatic macrophage: A descriptive synonym emphasizing its location (hepatic = liver) and cell type (macrophage).
- Stellate sinusoidal macrophage: A more detailed anatomical synonym describing its star-like shape and location in the liver sinusoids.
- Hepatic macrophage
- Stellate sinusoidal macrophage
- Fixed liver macrophage
The term refers exclusively to this specific macrophage population in the liver. It is an eponym, named after the German anatomist Karl Wilhelm von Kupffer who first described them. Its core meaning is tied to its location (liver sinusoids) and its function (phagocytosis of blood-borne debris).
- specialized cells in the liver that destroy bacteria, foreign proteins, and worn-out blood cells
