Cell death terminates normal cellular functions, including respiration, metabolism, growth and proliferation. Cell death can be non-programmed, for example as the result of accidental injury or trauma, or programmed. Types of programmed cell death include anoikis, apoptosis, autophagy, necrosis, necroptosis and pyroptosis.
Ferroptosis, a cell death mechanism induced by lipid peroxidation, is pivotal in tumor suppression. A recent study shows that tumor repopulating cells evade ferroptosis and develop resistance to therapy via subverting a lipid metabolism enzyme.
The endoplasmic reticulum (ER) is a major site of lipid peroxidation during ferroptosis. Here authors show that the ER protein IRE1α determines ferroptosis induction via regulating glutathione synthesis independent of the unfolded protein response.

Reversible S-palmitoylation regulates gasdermin D cleavage, membrane translocation and pore formation to control pyroptosis following bacterial infection.
Diverse, specialized immune cells defend against pathogens and cancer cells. A new study reveals the comprehensive lipid compositions of these cells, with unique lipidomes associated with various immune cell types. They show that cell-specific lipid compositions determine a key functional phenotype: their susceptibility to ferroptosis.
Detection of intracellular lipolysaccharide (LPS) activates an immune response initiated by the non-canonical inflammasome. ATGL has now been identified as a negative regulator of this pathway that dampens inflammation by removing LPS’ acyl chains, preventing the activation of inflammatory caspases and cytokines.
