Pyroptosis, as a form of programmed cell death, has many morphological differences as compared to apoptosis.Both pyroptosis and apoptosis undergo chromatin condensation, but during apoptosis, the nucleus breaks into multiple chromatin bodies; in pyroptosis, the nucleus remains intact. [16]
Macrophages (/ ˈ m æ k r oʊ f eɪ dʒ /; abbreviated Mφ, MΦ or MP) are a type of white blood cell of the innate immune system that engulf and digest pathogens, such as cancer cells, microbes, cellular debris and foreign substances, which do not have proteins that are specific to healthy body cells on their surface.
These inflammatory cytokines cannot be cleared and inflammatory mediators cause fever, cytopenias, coagulopathy, and central nervous system inflammation, which can progress to sepsis-like pathophysiology, shock, and death. The progression of macrophage activation in the context of rheumatic diseases is historically called MAS, and in the ...
Activated CD8 + T cells destroy target cells on contact, whereas activated macrophages produce hydrolytic enzymes and, on presentation with certain intracellular pathogens, transform into multinucleated giant cells. The overreaction of the helper T cells and overproduction of cytokines damage tissues, cause inflammation, and cell death.
Despite marked systemic inflammation, the erythrocyte sedimentation rate (ESR) is paradoxically depressed, caused by low fibrinogen levels. The low ESR helps to distinguish the disorder from a flare of the underlying rheumatic disorder, in which case the ESR is usually elevated. A bone marrow biopsy or aspirate usually shows hemophagocytosis.
Necrosis (from Ancient Greek νέκρωσις (nékrōsis) 'death') is a form of cell injury which results in the premature death of cells in living tissue by autolysis. [1] The term "necrosis" came about in the mid-19th century and is commonly attributed to German pathologist Rudolf Virchow , who is often regarded as one of the founders of ...
Due to its proinflammatory action, a proinflammatory cytokine tends to make the disease itself or the symptoms correlated to a disease worse by causing fever, inflammation, tissue destruction, and in some cases, even shock and death. [7] Excessive amounts of proinflammatory cytokines have been shown to cause detrimental effects [2]
Chronic systemic inflammation (SI) 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 ...
