Hepatocyte nuclei are round with dispersed chromatin and prominent nucleoli. Anisokaryosis (or variation in the size of the nuclei) is common and often reflects tetraploidy and other degrees of polyploidy, a normal feature of 30-40% of hepatocytes in the adult human liver. [4] Binucleate cells are also common. [citation needed]
A major differential diagnosis of HLH is Griscelli syndrome (type 2). This is a rare autosomal recessive disorder characterized by partial albinism, hepatosplenomegaly, pancytopenia, hepatitis, immunologic abnormalities, and lymphohistiocytosis. Most cases have been diagnosed between 4 months and 7 years of age, with a mean age of about 17 months.
Phagoptosis occurs when signals on the surface of a (target) cell activate phagocytic receptors on a phagocyte, inducing uptake into a phagosome, where the cell is killed and digested. Phagoptosis (cell death by phagocytosis) is a type of cell death caused by the cell being phagocytosed (i.e. eaten) by another cell, and therefore this form of ...
Unconjugated bilirubin is a breakdown product of heme (a part of hemoglobin in red blood cells). The liver is responsible for clearing the blood of unconjugated bilirubin, by 'conjugating' it (modified to make it water-soluble) through an enzyme named UDP-glucuronyl-transferase. When the total bilirubin level exceeds 17 μmol/L, it indicates ...
Cell counting is any of various methods for the counting or similar quantification of cells in the life sciences, including medical diagnosis and treatment.It is an important subset of cytometry, with applications in research and clinical practice.
Phagocytes of humans and other animals are called "professional" or "non-professional" depending on how effective they are at phagocytosis. [7] The professional phagocytes include many types of white blood cells (such as neutrophils, monocytes, macrophages, mast cells, and dendritic cells). [8]
The most frequent liver cancer, accounting for approximately 75% of all primary liver cancers, is hepatocellular carcinoma (HCC). [15] HCC is a cancer formed by liver cells, known as hepatocytes, that become malignant. In terms of cancer deaths, worldwide HCC is considered the 3rd most common cause of cancer mortalities. [16]
Overview of phagocytosis Phagocytosis versus exocytosis. Phagocytosis (from Ancient Greek φαγεῖν (phagein) 'to eat' and κύτος (kytos) 'cell') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the phagosome.
