Oxidative stress is a feature of many disease conditions. Oxidative stress can activate a number of cellular pathways leading to cell death, including a distinct iron-dependent pathway involving lipid peroxidation, termed ferroptosis, but cells have evolved complex mechanisms to respond to these stresses. Here, we briefly summarise current evidence linking caveolae to the cellular oxidative stress response. We discuss recent studies in cultured cells and in anin vivomodel suggesting that lipid peroxidation driven by oxidative stress causes disassembly of caveolae to release caveola proteins into the cell where they regulate the master transcriptional redox controller, nuclear factor erythroid 2-related factor 2. These studies suggest that caveolae maintain cellular susceptibility to oxidative stress-induced cell death and suggest a crucial role in cellular homeostasis and the response to wounding.
