TL;DR: It is demonstrated that necroptosis contributes to delayed mouse ischemic brain injury in vivo through a mechanism distinct from that of apoptosis and offers a new therapeutic target for stroke with an extended window for neuroprotection.
Abstract: The mechanism of apoptosis has been extensively characterized over the past decade, but little is known about alternative forms of regulated cell death. Although stimulation of the Fas/TNFR receptor family triggers a canonical 'extrinsic' apoptosis pathway, we demonstrated that in the absence of intracellular apoptotic signaling it is capable of activating a common nonapoptotic death pathway, which we term necroptosis. We showed that necroptosis is characterized by necrotic cell death morphology and activation of autophagy. We identified a specific and potent small-molecule inhibitor of necroptosis, necrostatin-1, which blocks a critical step in necroptosis. We demonstrated that necroptosis contributes to delayed mouse ischemic brain injury in vivo through a mechanism distinct from that of apoptosis and offers a new therapeutic target for stroke with an extended window for neuroprotection. Our study identifies a previously undescribed basic cell-death pathway with potentially broad relevance to human pathologies.

TL;DR: TNFR1-mediated-signal transduction includes a checkpoint, resulting in cell death (via complex II) in instances where the initial signal fails to be activated, and the cell survives.

TL;DR: The identification of a small molecule called necrosulfonamide that specifically blocks necrosis downstream of RIP3 activation is reported, which implicate MLKL as a key mediator of necrosis signaling downstream of the kinase RIP3.

TL;DR: The findings suggest that RIP3 controls programmed necrosis by initiating the pronecrotic kinase cascade, and that this is necessary for the inflammatory response against virus infections.

TL;DR: Evidence now reveals that necrosis can also occur in a regulated manner, and necroptosis participates in the pathogenesis of diseases, including ischaemic injury, neurodegeneration and viral infection, thereby representing an attractive target for the avoidance of unwarranted cell death.
Abstract: For a long time, apoptosis was considered the sole form of programmed cell death during development, homeostasis and disease, whereas necrosis was regarded as an unregulated and uncontrollable process. Evidence now reveals that necrosis can also occur in a regulated manner. The initiation of programmed necrosis, 'necroptosis', by death receptors (such as tumour necrosis factor receptor 1) requires the kinase activity of receptor-interacting protein 1 (RIP1; also known as RIPK1) and RIP3 (also known as RIPK3), and its execution involves the active disintegration of mitochondrial, lysosomal and plasma membranes. Necroptosis participates in the pathogenesis of diseases, including ischaemic injury, neurodegeneration and viral infection, thereby representing an attractive target for the avoidance of unwarranted cell death.
