orchidectomy increases activity of pyrrolidone carboxypeptidase type II, testosterone replacement returns it to control levels

central nervous system

atrium and ventricle

12 to 14% of cell profiles express pyroglutamyl peptidase II mRNA in the medial septum-diagonal band of Broca, in this region the specific activity of the enzyme is relatively high. Injection of the pyroglutamyl peptidase II inhibitor p-Glu-Asn-Pro-7-amido-4-methylcoumarin into the medial septum enhances the effect of thyrotropin-releasing hormone. The injection of a phosphinic thyrotropin-releasing hormone analog, a higher affinity inhibitor of pyroglutamyl peptidase II, diminishes the duration of ethanol-induced loss of righting reflex by itself
