Abstract
The tight correlation of the parenchymal de novo expression of the PBBS with the presence of activated glial cells, that in turn are usually only found in tissue affected by progressive disease, establishes the PBBS as a generic marker for the detection and measurement of active disease processes in the brain. Specific radioligands of the PBBS for use in positron emission tomography (PET) may thus provide a sensitive in vivo index of neuropathological activity. Whilst prototype ligands for the PBBS are available, future research needs to focus on the development of new ligands with improved pharmacodynamic properties and the ability to discriminate between the different, still insufficiently understood functional states of the peripheral benzodiazepine receptor complex.
