Ferroptosis is an iron-dependent mechanism of regulated necrosis that is driven by the robust oxidation of polyunsaturated fatty acid-containing phospholipids. This Review describes the fundamental mechanisms of ferroptosis, the potential contribution of ferroptosis to kidney disease and therapeutic strategies for targeting ferroptosis.

Two studies have applied a mechanical stimulus directly to a cilium, independent of a chemical signal, and demonstrated that force-based bending of a single nodal axoneme is sufficient to induce intraciliary Ca²⁺ flux in a PKD2-dependent manner, which propagates to drive asymmetric gene expression.

In this Review, the authors describe the roles of lysosomes in cellular clearance, autophagy, cell signalling, nutrient sensing and metabolic adaptation. They also discuss lysosome abnormalities in metabolic and autoimmune diseases and potential lysosome-targeting therapeutic strategies.

Sepsis-associated acute kidney injury (SA-AKI) is linked with poor outcomes in critically ill patients. This Consensus Statement from the Acute Disease Quality Initiative discusses the definition, epidemiology and pathophysiology of SA-AKI, fluid, resuscitation and extracorporeal therapies, and the role of biomarkers in risk stratification and diagnosis.
