From: Border-associated macrophages in the central nervous system
Distinct macrophage subsets in the central nervous system. Parenchyma: microglia; Brain-circulation interface: macrophages located in the meninges, choroid plexus, and perivascular spaces; Migrated from blood: monocytes that migrate into the brain from a dysregulated brain–blood barrier and differentiate into macrophages.
