Piecemeal necrosis in liver aka interface hepatitis is necrosis of the limiting plates, by inflammatory cells. It may be identified as actual necrosis of cells or by irregularity of the limiting plates which is caused IOS's hepatocytes and replacement with inflammatory cells and/or fibrosis.
Hepatocyte growth factor (HGF) or scatter factor (SF) is a paracrine cellular growth, motility and morphogenic factor. It is secreted by mesenchymal cells and targets and acts primarily upon epithelial cells and endothelial cells , but also acts on haemopoietic progenitor cells and T cells .
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
The primary risks include alcohol, type 2 diabetes, and obesity. [ 1 ] [ 3 ] Other risk factors include certain medications such as glucocorticoids , and hepatitis C . [ 1 ] It is unclear why some people with NAFLD develop simple fatty liver and others develop nonalcoholic steatohepatitis (NASH), which is associated with poorer outcomes. [ 1 ]
Obesity is associated with a higher risk of primary liver cancer. [36] As shown with mice, obese mice are prone to liver cancer, likely due to two factors. Obese mice have increased pro-inflammatory cytokines.
The hepatocyte plates are one cell thick in mammals and two cells thick in the chicken. Sinusoids display a discontinuous, fenestrated endothelial cell lining. The endothelial cells have no basement membrane and are separated from the hepatocytes by the space of Disse, which drains lymph into the portal tract lymphatics. [citation needed]
Surgery carries more risks for individuals with NASH cirrhosis, with a review estimating overall morbidity to be 21%. For people with MASLD who have undifferentiated cirrhosis, the APWG recommends an investigation to determine the cause of the cirrhosis as well as the person's liver function and whether they have portal hypertension.
Autoimmune hepatitis is commonly treated by immunosuppressants such as the corticosteroids prednisone or prednisolone, the active version of prednisolone that does not require liver synthesis, either alone or in combination with azathioprine, and some have suggested the combination therapy is preferred to allow for lower doses of ...
