This manifests as lipid peroxidation, mitochondrial damage, and glutathione (an endogenous antioxidant) depletion. [7] Damaged hepatocytes release Danger associated molecular patterns (DAMPs) which are molecules that lead to further activation of the immune system's inflammatory response and further hepatocyte damage. [7]
The prevailing theory for the development of autoimmune hepatitis is thought to be the interplay of genetic predisposition, an environmental trigger (virus, drugs, herbs, immunizations), and failure of the native immune system resulting in chronic inflammation of hepatocytes and subsequent fibrosis of the liver. [7] [8] [9]
[17] [59] Rather, infection of liver cells activates the innate and adaptive arms of the immune system leading to an inflammatory response which causes cellular damage and death, including viral-induced apoptosis via the induction of the death receptor-mediated signaling pathway.
An immune system disorder but not autoimmune. Idiopathic giant-cell myocarditis: No consistent evidence of autoimmune cause though the disease has been found comorbid with other autoimmune diseases. [124] Idiopathic pulmonary fibrosis: Autoantibodies: SFTPA1, SFTPA2, TERT, and TERC. IgA nephropathy: An immune system disorder but not an ...
Water-soluble fractions of particulate matter are the most important part of translocation to the liver, through extrapulmonary circulation. When particulate matter gets into the bloodstream, it combines with immune cells and stimulates innate immune responses. Pro-inflammatory cytokines are released and cause disease progression. [46]
Ischemic hepatitis, also known as shock liver, is a condition defined as an acute liver injury caused by insufficient blood flow (and consequently insufficient oxygen delivery) to the liver. [5]
The complications are hepatic encephalopathy and impaired protein synthesis (as measured by the levels of serum albumin and the prothrombin time in the blood). The 1993 classification defines hyperacute as within 1 week, acute as 8–28 days, and subacute as 4–12 weeks; [ 1 ] both the speed with which the disease develops and the underlying ...
Chronic systemic inflammation is the result of release of pro-inflammatory cytokines from immune-related cells and the chronic activation of the innate immune system.It can contribute to the development or progression of certain conditions such as cardiovascular disease, cancer, diabetes mellitus, chronic kidney disease, non-alcoholic fatty liver disease, autoimmune and neurodegenerative ...
