The meninges, a four-layer membrane-like enclosure around the central nervous system (CNS), house a significant population of immune cells; however, the exact immune processes remain elusive. Recent identification of meningeal lymphatic vessels has shed light on the involvement of meninges in metabolite clearance, immune surveillance, and response. Here, we provide a comprehensive review of advancements in meningeal immunity research and its implications for associated disorders. Additionally, potential avenues for future investigations in the realm of meningeal immunity are suggested.
