604-Dynamic Dural Sinuses: Gatekeepers of Meningeal Immunity
This paper examine the dural sinuses as a specialized interface that manages both fluid dynamics and immune surveillance in the brain. Researchers identified sinus endothelial cells (SECs) as highly active regulators that adjust their boundaries to let immune cells move between the blood and the surrounding perisinus space. This process, often appearing as cellular ruffling, is essential for defending the central nervous system against viral infections and other circulating pathogens. The study highlights that RAMP2 signaling and specific adhesion molecules are critical for maintaining this…
