Ferroptosis is an iron-dependent form of cell death that results from excess lipid peroxidation in cellular membranes. Within the last decade, physiological and pathological roles for ferroptosis have been uncovered autoimmune diseases, inflammatory conditions, infection, cancer biology. Excitingly, metabolism may be targeted to induce by cancers are resistant other forms death. sensitivity regulated oxidative stress, metabolism, iron which all influenced tumor microenvironment (TME). Whereas some types shown adapt these stressors, it not clear how immune cells regulate their sensitivities ferroptosis. In this review, we discuss mechanisms different subsets, influences infiltrate TME, interactions can determine epithelial-to-mesenchymal transition (EMT) metastasis. While much focus has placed on inducing cells, important considerations ferroptosis-modulating strategies impact anti-tumor immunity. From perspective, also promising immunotherapies field challenges associated with targeting specific populations.

The immunosuppressive tumor microenvironment (TME) in glioblastoma (GBM) is mainly driven by tumor-associated macrophages (TAMs). We explored whether their sustained iron metabolism and activity were correlated, blocking the central enzyme of heme catabolism pathway, oxygenase-1 (HO-1), could reverse tolerogenic activity. To this end, we investigated bone marrow-derived (BMDMs) isolated from GBM specimens vitro-derived (Mφ) healthy donor (HD) blood monocytes. found that HO-1 inhibition abrogated both BMDMs Mφ, immunosuppression requires cell-to-cell contact soluble factors, as abolished IL-10 release, significantly reduced STAT3 activation well PD-L1 expression. Interestingly, not only did downregulate IDO1 ARG-2 gene expression, but also enzymatic Moreover, T cell status affected expression activity, which upregulated presence activated, resting, cells. Our results highlight crucial role TME demonstrate feasibility reprogramming them an alternative therapeutic strategy for restoring immune surveillance.
