Linkermann et al. provide the first evidence for a possible biochemical mechanism of necrotic kidney cell death associated with renal ischemia/reperfusion-induced acute kidney injury. The mechanisms of several pathways resulting in programmed necrosis were recently elucidated and rely on receptor-interacting protein kinases 1 and 3. Using an inhibitor of one of these kinases, Linkermann et al. were able to ameliorate functional and morphologic kidney damage after ischemia/reperfusion.
