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 .

Structural changes of cells undergoing necrosis and apoptosis. 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]
It is proposed that both pyroptosis and necroptosis may act as defence systems against pathogens when apoptotic pathways are blocked. [ citation needed ] Summary of the different morphologies, mechanisms and outcomes of three most well-characterized forms of cell death (apoptosis, pyroptosis, and necrosis) [ 10 ] [ 6 ] [ 17 ]
The Mechanisms of Apoptosis Archived 2018-03-09 at the Wayback Machine Kimball's Biology Pages. Simple explanation of the mechanisms of apoptosis triggered by internal signals (bcl-2), along the caspase-9, caspase-3 and caspase-7 pathway; and by external signals (FAS and TNF), along the caspase 8 pathway. Accessed 25 March 2007.
Damage-associated molecular patterns (DAMPs) [1] are molecules within cells that are a component of the innate immune response released from damaged or dying cells due to trauma or an infection by a pathogen. [2]
Hints and the solution for today's Wordle on Saturday, February 22.
Immunogenic cell death is any type of cell death eliciting an immune response.Both accidental cell death and regulated cell death can result in immune response. Immunogenic cell death contrasts to forms of cell death (apoptosis, autophagy or others) that do not elicit any response or even mediate immune tolerance.
