title: D-2 dopamine receptor synthesis and turnover in rat striatum.
abstract: Direct injection of phenoxybenzamine into rat striatum inhibited apomorphine-induced stereotyped behavior. This inhibition corresponded well with the inhibition of D-2 dopamine receptor labelling with [3H]spiroperidol. Both the behavioral response and the receptor level were completely restored within 5 days after the injection. The recoveries of both were blocked by cycloheximide. The rate of synthesis and half-life of the D-2 receptor associated with the stereotyped behavior were calculated to be 6.9 fmol/mg protein per h and 28 h, respectively.
