Lipid recycling by macrophage cells drives the growth of brain cancer

Nature, Published online: 11 September 2024; doi:10.1038/d41586-024-02868-7

In brain tumours, immune cells called macrophages scavenge lipid debris from the myelin sheath of neurons. These lipid-laden macrophages cause immunosuppression, and their transfer of lipids to tumours fuels cancer growth.
