A new ally in fighting brain diseases: our very own skull

Alzheimer's, stroke, multiple sclerosis, and other neurological diseases cause severe damage due to neuroinflammation mediated by immune cells. Managing this inflammation poses a significant medical challenge because the brain is protected by the skull and additional surrounding membranes that make the brain less accessible for treatment approaches. Scientists had previously discovered pathways going from the bone marrow of the skull towards the brain, allowing immune cell movement. Now, new research revealed that cells in the skull’s bone marrow are unique in their composition and in their disease response. These findings offer new possibilities for the diagnosis and treatment of neurological diseases and revolutionize brain health monitoring in the future with non-invasive skull imaging. The results are now published in Cell.

Neurological diseases such as Alzheimer's, stroke, and multiple sclerosis have a devastating impact on the lives of millions worldwide. A common feature is neuroinflammation, an internal "fire" in the brain that can cause severe damage by activation of immune cells and release of inflammatory molecules. However, due to the brain's relative inaccessibility, as it is shielded by the skull and three additional layers of protection in the form of membranes, controlling and monitoring this inflammation has been a major challenge. A team of scientists around Prof. Ali Ertürk at Helmholtz Munich in collaboration with researchers from the Ludwig-Maximilians-Universität München (LMU) and the Technical University of Munich (TUM) sought to address this unmet need.
