Figure 1

(A) Scheme shows how the brain is enveloped by the meninges that contain Mast cells (MCs) in both the dura mater and pia mater. (B) Before entering the brain parenchyma, blood vessels course on the surface of the brain between the dura mater and pia mater. Therefore, as a resident immune cell in the meninges, the MC has the potential to influence blood vessels and to function as a gatekeeper to influence brain inflammation and pathology.
