N2 - For anthracycline-based chemotherapy to be immunogenic, dying cancer cells must release annexin A1 (ANXA1) that subsequently interacts with the pattern recognition receptor, formyl peptide receptor 1 (FPR1), on the surface of dendritic cells (DC). Approximately 30% of individuals bear loss-of-function alleles of FPR1, calling for strategies to ameliorate their anticancer immune response. Here, we show that immunotherapy with a ligand of Toll-like receptor-3, polyinosinic:polycytidylic acid (pIC), restores the defi cient response to chemotherapy of tumors lacking ANXA1 developing in immunocompetent mice or those of normal cancers growing in FPR1-defi cient mice. This effect was accompanied by improved DC- and T-lymphocyte-mediated anticancer immunity. Of note, carcinogen-induced breast cancers precociously developed in FPR1-defi cient mice as compared with wild-type controls. A similar tendency for earlier cancer development was found in patients carrying the loss-of-function allele of FPR1. These fi ndings have potential implications for the clinical management of FPR1-defi cient patients.
