Abstract

Necrosis is a primary form of cell death in a variety of human pathologies. The deleterious nature of necrosis, including its propensity to promote inflammation, and the relative lack of the cells displaying necrotic morphology under physiologic settings, such as during development, have contributed to the notion that necrosis represents a form of pathologic stress-induced nonspecific cell lysis. However, this notion has been challenged in recent years by the discovery of a highly regulated form of necrosis, termed regulated necrosis or necroptosis. Necroptosis is now recognized by the work of multiple labs, as an important, drug-targetable contributor to necrotic injury in many pathologies, including ischemia-reperfusion injuries (heart, brain, kidney, liver), brain trauma, eye diseases, and acute inflammatory conditions. In this review, we describe the methods to analyze cellular necroptosis and activity of its key mediator, RIP1 kinase.
