Necroptosis is a programmed form of necrosis, or inflammatory cell death. [1] Conventionally, necrosis is associated with unprogrammed cell death resulting from cellular damage or infiltration by pathogens, in contrast to orderly, programmed cell death via apoptosis .

Necroptosis is characterized by necrotic morphology. [2] This type of cell death is induced by extracellular and intracellular microtraumas detected by death or damage receptors. For example, FAS , TNFR1 and pattern recognition receptors may initiate necroptosis.
Although both pyroptosis and necroptosis are triggered by membrane pore formation, pyroptosis is more controlled. Cells that undergo pyroptosis exhibit membrane blebbing and produce protrusions known as pyroptotic bodies, a process not found in necroptosis. [19] Also, necroptosis works in a caspase-independent fashion.
Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
An unknown illness first discovered in three children who ate a bat has rapidly killed more than 50 people in northwestern Congo over the past five weeks, health experts say.
Each year for the past 78 years, the Bulletin of the Atomic Scientists has published a new Doomsday Clock, suggesting just how close – or far – humanity is to destroying itself.
Ferroptosis (also known as oxytosis) is a type of programmed cell death dependent on iron and characterized by the accumulation of lipid peroxides.Ferroptosis is biochemically, genetically, and morphologically distinct from other forms of regulated cell death such as apoptosis and necroptosis. [1]
