CHAT and Dystonia: Post-mortem histopathological measures of choline acetyltransferase (ChAT) or in vivo PET measures of [18F]fluoroethoxybenzovesamicol, (−)-[18F] FEOBV,(−)-(2R,3R)-trans-2-hydroxy-3-(4- phenylpiperidino)-5-(2-[18F]fluoroethoxy)-1,2,3,4-tetralin (52) or (−)-(1-(8-(2-[(18)F)fluoroethoxy)-3-hydroxy-1,2,3,4-tetrahydronaphtalen-2-yl)-pi peridi n -4 -yl) (4-fluorophenyl)methanone([18F]VAT) (53) may provide clues with respect to altered ChI activity during the transient dystonia phase in this NHP MPTP model.
