Portal ceroid-laden macrophages mean necrosis of hepatocytes at the interface of portal tracts. The necrosis may be induced by the inflammation including interface hepatitis. Macrophages phagocyte the necrotic hepatocytes, then they have abundant brownish cytoplasm, which is called ceroid-laden feature.
What else can I help you with?
How do macrophages replicate?
Macrophages do not replicate. The bone marrow produces Monocytes which when they find a damaged area transform into Macrophages.
Which organ does NOT contain fixed macrophages?
The brain does not contain fixed macrophages. Instead, microglia serve as the resident macrophages in the brain.
Are macrophages responsible for allergic reactions?
No, macrophages are responsible for removing dying or dead cells in the early stages of inflammation. Macrophages essentially ingest these.
Where is the stellate macrophages of the liver?
Stellate macrophages of the liver, also known as Kupffer cells, are located in the liver sinusoids, which are specialized blood vessels within the hepatic tissue. They play a crucial role in the immune response by phagocytosing pathogens and debris in the bloodstream. Kupffer cells are positioned strategically to monitor blood as it flows from the portal vein and hepatic artery, allowing them to perform their functions effectively.
What is alveolar macrophages also known as?
Alveolar macrophages, aka DUST CELLS.
What happens to monocytes when they enter tissues?
They become larger and turn into macrophages
What is murine macrophages?
Murine means "of, related to, or affecting rodents of the family Muridae," like mice. Murine macrophages are simply macrophages of these types of animals.
How does abnormal hepatopedal flow in the portal vein happen?
Abnormal hepatopedal flow in the portal vein occurs when blood flow is redirected towards the liver due to increased resistance or obstruction in the hepatic outflow, often caused by conditions like hepatic cirrhosis, portal vein thrombosis, or hepatic venous obstruction. This reversal of flow can lead to increased portal pressure and complications such as varices or ascites. Additionally, abnormal flow can result from altered hemodynamics or pathological changes in the liver. Overall, the disruption in normal portal circulation can significantly impact liver function and systemic circulation.
Some monocytes enter the tissues and mature into phagocytic cells called?
Macrophages
What are immature monocytes?
MACROPHAGES (Some Monocytes enter tissue, enlarge, and Mature into Macrophages).
How does macrophages fight disease?
macrophages engulf, or eat , any microorganisms or viruses that enter your body
Which white blood cells turn into macrophages in tissue?
Macrophages are a type of white blood cell that begin their lives as monocytes. monocytes develop into macrophages or dendritic cells. For stem cells, please visit BOC Sciences
