Abstract

It is increasingly clear that the central nervous system (CNS) relies significantly on both adaptive and innate immune cells for its repair and lifelong maintenance. These interactions hold profound implications for brain aging and neurodegeneration. Recent work by Smyth et al. describes newfound anatomical connections between the brain and dura mater, which they named the arachnoid cuff exit points.
