Perivascular Macrophages is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Perivascular macrophages (PVMs), also known as perivascular [microglia](/cell-types/microglia-neuroinflammation) or perivascular resident macrophages of the brain (PVMBMs), are specialized resident immune cells located adjacent to cerebral blood vessels. These cells represent a distinct population from both parenchymal microglia and peripheral monocytes, with unique developmental origins, molecular signatures, and functional roles in CNS homeostasis and disease.

Overview
Perivascular macrophages reside in the perivascular space (Virchow-Robin space) between the endothelial basement membrane and the glia limitans. They are strategically positioned to monitor blood-derived signals and regulate traffic between the circulation and the brain parenchyma. [@williams2001]
