Inhibition of RANK signaling as a potential immunotherapy in breast cancer

Abstract

RANK signaling in mouse mammary tumor cells exerts an immunosuppressive environment by promoting the infiltration of pro-tumorigenic neutrophils and preventing CD8 T cell recruitment. Single-agent denosumab led to an increased tumor immune infiltration by lymphocytes and CD8 + T cells in breast cancer patients, supporting the immunomodulatory role of RANK signaling.
