Sympathetic Nerves Slowed Mouse Melanoma via Norepinephrine on Alpha Adrenergic Receptors on Macrophages
TL;DR: A 2026 study in Neuron from Weill Cornell used mouse melanoma models to find that sympathetic nerves growing into tumors release norepinephrine, which activates alpha adrenergic receptors on tumor-associated macrophages and reduces their pro-tumor numbe…
