The central nervous system (CNS) is an immunologically specialized tissue protected by a blood–brain barrier. The CNS parenchyma is enveloped by a series of overlapping membranes that are collectively referred to as the meninges. The meninges provide an additional CNS barrier, harbor a diverse array of resident immune cells, and serve as a crucial interface with the periphery. Recent studies have significantly advanced our understanding of meningeal immunity, demonstrating how a complex immune landscape influences CNS functions under steady-state and inflammatory conditions. The location and activation state of meningeal immune cells can profoundly influence CNS homeostasis and contribute to neurological disorders, but these cells are also well equipped to protect the CNS from pathogens. In this review, we discuss advances in our understanding of the meningeal immune repertoire and provide insights into how this CNS barrier operates immunologically under conditions ranging from neurocognition to inflammatory diseases. The CNS is protected by layers of cells that are collectively referred to as the meninges. Far from being an inert connective tissue, emerging data indicate that the meninges serve as an interface with the periphery and actively contribute to CNS homeostasis and immunity. The meningeal layers have a far more diverse immune repertoire than the CNS parenchyma and are innervated, have lymphatic drainage (dura), contain permeable blood vessels (dura), and support robust inflammatory responses. The meninges serve as a gatekeeper that isolates the brain and spinal cord parenchyma from the periphery. The meninges develop and support immune responses far more readily than the parenchyma, which can both protect and harm the CNS. The meninges are highly innervated, which can influence meningeal immunity and vascular tone. Both sterile and infectious challenges can trigger meningeal inflammation, which results in subsequent degradation of the glial limitans and immune infiltration into the CNS parenchyma. This process can give rise to neurological disorders. Therapeutically, the meninges are far easier to access from the periphery than the CNS parenchyma (especially the dura mater). Modulation of meningeal immunity represents a promising therapeutic target to treat inflammatory neurological disorders and possibly to regulate neural homeostasis.
