The interplay between neuronal activity and tumor progression is well-established. Here, the authors demonstrate that blockade of β-adrenergic signaling via administration of propranolol suppresses lung metastasis in multiple mouse tumor models by enhancing the accumulation of cytotoxic CD4 T cells while reducing CCR2+ monocytes, highlighting the re-purposing of β-blockers as a valid therapeutic approach for cancer treatment.
