Indeed, in the rodent model of cerebral ischemia, Martín et al. have assessed in parallel the in vivo expression of both α4β2 (nicotinic acetylcholine receptors) and TSPO in reactive glial cells using 2-18F-fluoro-A85380 and 11C-PK11195, respectively [219]. Here, TSPO is linked to Cerebral ischemia.
