Kupffer Cells

Kupffer Cells - liver protectors

The liver is one of the most important organs in the body, performing many functions, including clearing the blood of toxins and other harmful substances. One of the key players in this process are Kupffer cells, which line the sinusoidal capillaries of the liver along with endothelial cells.

Kupffer cells are phagocytic cells that protect liver cells from many toxic influences. These cells engage in phagocytosis, a process in which they capture and process various particles, including microorganisms, red blood cell fragments, pigment granules, and other harmful substances.

Kupffer cells also perform other important functions, such as the synthesis of cytokines and regulation of the immune response in the liver. In addition, they are involved in the metabolism of fats and carbohydrates, as well as in the regulation of blood flow in the liver.

Although Kupffer cells perform important functions, they can also become the target of various diseases and pathological processes. For example, in chronic liver diseases such as cirrhosis, Kupffer cells can become overactive and begin to attack healthy liver cells, leading to severe consequences.

In general, Kupffer cells play an important role in protecting the liver and maintaining its functions. Understanding their role in liver biology may help develop new treatments for liver disease and improve overall health.



Kupffer cells are specialized phagocytic liver cells that play an important role in protecting the organ from various toxic substances. They line the sinusoidal capillaries that are found in the liver and participate in phagocytosis, that is, the absorption and destruction of various particles and microorganisms.

Kupffer cells have many functions, including protecting liver cells from the effects of various toxins such as alcohol, drugs and other harmful substances. They are also involved in the metabolism of iron, cholesterol and other important metabolic processes in the liver.

In addition, Kupffer cells often contain pigmented granules that appear as a result of the breakdown of hemoglobin in the blood. These granules may be visible on microscopic examination of the liver and may indicate the presence of anemia or other blood disorders.

It is important to note that Kupffer cells also play an important role in the liver's immune system. They can participate in the immune response to various infectious agents and protect the liver from viruses and bacteria.

In general, Kupffer cells are important phagocytes in the liver and play a key role in maintaining the health of the organ and protecting it from various insults.



Kupffer cells are a phagocytic cell of the liver, present along with the endothermic, sinusoidal capillaries of the liver and macrophages, which act as a defender of the liver cells from many toxins, nutrients and microorganisms. In liver tissue, Kupffer cells are located along the sinusoidal capillaries, where they form a protective cell wall around the endothermal and peripheral artery canals. They act as a filter, absorbing particles and microbes and removing them through the sinus tubules into the bile sac. The mechanism of phagocytosis of these cells is complex and requires coordination with numerous signals and signaling proteins. Interestingly, the presence of these cells is strongly influenced by regeneration, as damaged parts of the liver can lose or gain it. In addition, it is also a source of possible complications in various conditions, such as hypoxia, heavy metal poisoning, intoxication with viruses and drugs. Due to their importance and multinucleated structure, Kupffer cells play a critical role in maintaining liver health and regulating several homeostatic systems.
