Multimodal immunostimulation to control BRCA1-defective ovarian carcinoma

Depending on intensity and duration, STING1 (stimulator of interferon response cGAMP interactor 1) signaling can restrain or promote tumor progression via both cancer cell-intrinsic and -extrinsic pathways. Bruand et al. recently identified a novel STING1-driven immunosuppressive pathway that can be targeted toward superior disease control in preclinical models of homologous recombination deficient (HRD) ovarian carcinoma.
