As promised, here's the deep dive on our recent article! Did you know the brain's "sewer drains" (dural sinuses) aren't passive pipes—they're dynamic, ruffling structures that actively guard immunity & regulate pressure?
As both a co-author and President & Founder of @neurosimplicity, I am excited to spotlight this groundbreaking discovery from the McGavern lab @NIH_NINDS in @Nature. Our Imaging Suite helped map the amazing cranial & neurovascular connections in unprecedented 3D detail! 🧠🔬

#Neuroimmunology #BrainImmunity The meninges enclose the brain and recent studies have shown that the dura contains extensive immune networks. Dural sinuses, traditionally viewed as passive venous conduits, function as dynamic interfaces for neuroimmune regulation.
Figure 1 details the dorsal dural sinus anatomy in mice: a continuous VE-cadherin+ endothelial layer with αSMA+ smooth muscle bands and vimentin support along the transverse sinuses, sagittal sinuses, and rostral-rhinal hub. Multi-modal imaging (confocal whole mounts, light-sheet of cleared heads, micro-CT segmentation) reveals key cranial and neurovascular connections, including diploic veins linking skull bone marrow to sinuses and anastomoses between upper and lower sagittal sinuses.
Proud that the @neurosimplicity Imaging Suite supported the micro-CT 3D reconstructions, enabling precise mapping of these structures with reproducibility and multi-modal integration.
