Cell death, survival, proliferation and differentiation are the fundamental processes of life. Cell death plays a key role in embryonic development, maintaining the homeostasis of the organism and eliminating damaged cells. It was originally classified into three types (1): type I cell death (apoptosis), type II cell death (autophagy), and type III cell death (necrosis). All three types can be executed by different, sometimes overlapping, signaling pathways that respond to specific stimuli.
Necrosis is characterized by cell swelling, plasma membrane rupture, and loss of organelle structures without chromatin cohesion. Although necrosis can occur as a result of irreparable cellular damage, there is at least one pathway of active necrosis. This form of cell death involves several signaling pathways, all of which center on the activation of receptor-interacting protein kinase 3 (RIP3), which is activated upon recruitment to macromolecular complexes downstream of various cell surface receptors: DRs, Toll-like receptors (TLRs), and T-cell receptors (TCRs).
In addition, DNA damage can directly induce the formation of RIP3 activation platforms independent of cell surface receptor binding. Finally, RIP3-dependent necrosis is also triggered by cell membrane DNA sensors, DNA-dependent activator of interferon (DAI) regulatory factors following viral infection, and the presence of double-stranded viral DNA in the cell membrane.
