The research explores how the chemical 6-hydroxydopamine (6-OHDA), traditionally used to destroy sympathetic nerves, actually suppresses breast cancer growth through immune system activation rather than nerve loss. By comparing various denervation methods, scientists discovered that only 6-OHDA inhibits tumors by triggering cancer cells to produce interferon-beta (IFN-β) via the cGAS pathway. This surge in interferon leads to the development of specialized pro-inflammatory macrophages that express interferon-stimulated genes. These unique macrophages subsequently recruit and activate T helper…
