Abstract
Defects in BRCA1, a gene involved in homologous recombination DNA repair, are common in triple negative breast cancer. Here the authors show that Brca1 deficiency in preclinical breast cancer models is associated with the accumulation of myeloid derived suppressive cells and resistance to immune checkpoint blockade, that could be overcome by targeting S100A9 and CXCL12.
