Description Iron is an essential biomineral in human body. Here, we discover a new subset of ferric iron-loaded cancer-associated fibroblasts (FerroCAFs) that utilizes iron to induce immunosuppression in prostate cancer (PCa) and predicts an unfavorable clinical outcome. FerroCAFs secret myeloid-cell-associated proteins (MASP), including CCL2, CSF1 and CXCL1, to recruit immunosuppressive myeloid cells. Importantly, we demonstrate the existence of FerroCAFs in PCa from both mice and humans, as well as in human lung and ovarian cancers and identify a conserved cell surface marker, the poliovirus receptor (Pvr). Mechanistically, the accumulated iron in FerroCAFs is caused by Heme Oxygenase-1 (Hmox1)-mediated iron release from heme degradation. The intracellular iron activates the lysine demethylase 6B (Kdm6b), an iron-dependent epigenetic enzyme, to trigger an accessible chromatin state and transcription of MASP genes. Targeting the FerroCAFs by inhibiting the Hmox1/iron/Kdm6b signaling axis incurs anti-tumor immunity and significant tumor regression. Collectively, we uncover a novel iron-loaded FerroCAF cluster that drives immunosuppression through an iron-dependent epigenetic reprogramming mechanism and reveal new therapeutic targets to boost anti-tumor immunity.
