Ferroptosis is a recently described iron-dependent type of regulated necrosis driven by massive lipid peroxidation. While membrane rupture occurs during ferroptosis, a comprehensive appraisal of ferroptotic secretomes and their potential biological activity has been lacking. Here, we apply a multi-omics approach to provide an atlas of ferroptosis-induced secretomes and reveal a novel function in macrophage priming. Proteins with assigned DAMP and innate immune system function, such as MIF, heat shock proteins (HSPs), and chaperones, were released from ferroptotic cells. Non-protein secretomes with assigned inflammatory function contained oxylipins as well as TCA- and methionine-cycle metabolites. Interestingly, incubation of bone marrow-derived macrophages (BMDMs) with ferroptotic supernatants induced transcriptional reprogramming consistent with priming. Indeed, exposure to ferroptotic supernatants enhanced LPS-induced cytokine production. These results define a catalog of ferroptosis-induced secretomes and identify a biological activity in macrophage priming with important implications for the fine-tuning of inflammatory processes.}, cin = {A410}, ddc = {610}, cid = {I:(DE-He78)A410-20160331}, pnm = {311 - Zellbiologie und Tumorbiologie (POF4-311)}, pid = {G:(DE-HGF)POF4-311}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:40281125}, doi = {10.1038/s41418-025-01517-4}, url = {https://inrepo02.dkfz.de/record/300702}, }
