Scientists have uncovered hidden immune “security stations” in skull bone marrow that act as rapid-response defenders for the brain, potentially revolutionizing how we treat brain cancer and other neurological diseases. Found in mice and likely present in humans, these mini lymph nodes activate faster than other immune cells, offering a direct, localized defense system that challenges the old belief the brain is immune-protected. Research shows disrupting these hubs accelerates tumor growth, while boosting their activity with a gel treatment improved survival—hinting at future targeted…
