Resumen:
The brain regional distribution of membrane-bound pyroglutamate aminopeptidase-degrading thyrotropin-releasing hormone (TRH) in rat was studied using a specific radiometric assay. The distribution was not homogeneous: a 10-fold difference was observed between regions. The highest activity was detected in olfactory bulb while the lowest was in the cervical part of spinal cord. There was no correlation with the regional distribution of enzyme activity vs TRH levels, previously reported TRH receptors or in vitro TRH release. The differential distribution of this enzyme is consistent with the hypothesis that it is responsible for extracellular degradation of neuroactive peptides. © 1987.
