Skull's Hidden Role in Brain-Body Immune Connection

New research from King's College London reveals that the skull marrow and dural sinuses act as communication hubs between the brain's central immune system and the body's peripheral immune system. This challenges the traditional view of the blood-brain barrier as an absolute divide. The study found that inflammatory activity in these areas correlates with inflammation in both the brain and body, offering insights into conditions like depression. These findings could lead to innovative treatments targeting these hubs to address immune-related conditions more precisely.
