Advances in understanding ferroptosis mechanisms and their impact on immune cell regulation and tumour immunotherapy

Ferroptosis is a novel mode of iron-dependent non-apoptotic cell death that occurs mainly due to excessive accumulation of lipid peroxides. Numerous studies in recent years have shown that ferroptosis plays a vital role in the organism and has important interactions with immune cells. Ferroptosis has been shown to have great potential in tumour therapy through studying its mechanism of action. In addition, ferroptosis plays a major role in many types of tumour cells that can potently suppress the tumourigenesis and metastasis, provide a basis for the treatment of many malignant tumour diseases and become a novel therapeutic modality of antitumour immunity in the clinic. Current tumour immunotherapy for ferroptosis in combination with other conventional oncological modalities is not well elaborated. In this paper, we mainly discuss the connection of ferroptosis with immune cells and their mediated tumour immunotherapy in order to provide a better theoretical basis and new thinking about ferroptosis mediated antitumour immunity.
