The Peripheral Benzodiazepine Receptor is expressed in astrocytes and microglia in the CNS

In the resting CNS, PBR expression is thought to be restricted to astrocytes and microglia. PBR is present in the mitochondria of these cells in association with the voltage dependent anion channel and the adenine nucleotide transporter, forming the mitochondrial permeability transition pore. Note that PBR is situated on the outer mitochondrial membrane.
