Title Immunosubtyping of breast cancer reveals distinct myeloid cell biology and immunotherapy resistance mechanisms
Organism Mus musculus
Experiment type Expression profiling by high throughput sequencing
Summary Cancer-induced immune responses affect tumor progression and therapeutic response. In multiple murine models and clinical datasets, we identified large variations of neutrophils and macrophages, which define “immune subtypes” of triple negative breast cancer (TNBC) including neutrophil-enriched (NES) and macrophage-enriched subtypes (MES). Different tumor-intrinsic pathways and mutual regulation between macrophages/monocytes and neutrophils contribute to the development of dichotomous myeloid compartment. MES contains predominantly macrophages that are CCR2-dependent and exhibit variable responses to immune checkpoint blockade (ICB). NES exhibits systemic and local accumulation of immunosuppressive neutrophils (or granulocytic myeloid-derived suppressor cells (gMDSCs), is resistant to ICB, and contains a minority of macrophages that appear to be unaffected by CCR2 knockout. A MES-to-NES conversion mediated acquired ICB resistance of initially sensitive MES models. Our results demonstrate diverse myeloid cell frequencies, functionality, and potential roles in immunotherapies, and highlight the need to better understand the inter-patient heterogeneity of the myeloid compartment.
Overall design Transcritomic profiling of 1) eight different breast tumor cell lines cultured in vitro and 2) FACS-purified tumor-infiltrating neutrophils and macrophages from four breast tumors in vivo. Each sample was prepared in triplicate.
