Do Kupffer cells produce bile?
Kupffer cells, also known as stellate macrophages and Kupffer–Browicz cells, are specialized cells localized in the liver within the lumen of the liver sinusoids and are adhesive to their endothelial cells which make up the blood vessel walls….

How are Kupffer cells activated?
LPS can stimulate activation of Kupffer cell through TLR4 receptor[27]. Activation of Kupffer cells by LPS played important roles in the mechanism of various acute or chronic liver disease. Furthermore, LPS levels was increased in human or animal models of NASH [28].
What is the role of Kupffer cells in the liver?
Kupffer cells are resident liver macrophages and play a critical role in maintaining liver functions. Under physiological conditions, they are the first innate immune cells and protect the liver from bacterial infections.
What is the structure of a Kupffer cell?
Structure of Kupffer Cells The kupffer cells present in the liver are amoeboid shaped, they are attached to sinusoidal endothelial cells. The surface of kupffer cells contains pseudopodia, lamellipodia, and microvilli. They are projected in every direction.
Who was the first person to identify Kupffer cells?
Kupffer cells were first identified by Karl Wilhelm von Kupffer in 1876 using a gold chloride-staining method and were named “Sternzelle” (stellate cells) [2]. Initially, KCs were associated to the family of perivascular cells of the connective tissues or to the adventitial cells (pericytes).
What is the function of the Golgi body in Kupffer cells?
In the cell, the Golgi bodies are involved in the secretion and intracellular transport of vesicles. Known to be the organelle responsible for ribosome (for protein synthesis) synthesis, the rough ER is very abundant in Kupffer cells.
