Several years after the characterization of the role of receptor-interacting serine/threonine protein kinase 1 (RIPK1) in cell survival, inflammation and disease, RIPK1 was implicated in the regulation of a newly identified type of cell death known as necroptosis. This Timeline article describes the discoveries that shed light on the roles of RIPK1, RIPK3, mixed-lineage kinase domain-like protein (MLKL) and other regulators of necroptosis in controlling cell fate.
This year marks the tenth anniversary of the generation of induced pluripotent stem cells (iPSCs) by transcription factor-mediated somatic cell reprogramming. Takahashi and Yamanaka portray the path towards this ground-breaking discovery and discuss how, since then, research has focused on understanding the mechanisms underlying iPSC generation and on translating such advances to the clinic.
