TOPOGRAPHICAL AND SUBCELLULAR LOCALIZATION OF CHOLINE ACETYLTRANSFERASE IN RAT HIPPOCAMPAL REGION

TOPOGRAPHICAL AND SUBCELLULAR LOCALIZATION OF CHOLINE ACETYLTRANSFERASE IN RAT HIPPOCAMPAL REGION —Choline acetyltransferase (ChAc) was localized in discrete layers in hippocampus regio superior and in area dentata. The highest activity in hippocampus was found in a narrow infrapyramidal zone, but high activities were also observed in the rest of stratum oriens and in stratum pyramidale. In area dentata the highest activities were found in a narrow supragranular zone and in hilus fasciae dentatae. The localization corresponded very closely to that of acetylcholinesterase. The main part of ChAc activity was confined to the synaptosome fraction. The results are compatible with the view that pyramidal and granular cells are excited by cholinergic boutons, mainly located on the basal or apical dendrites near the somata. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Neurochemistry Wiley

Abstract

—Choline acetyltransferase (ChAc) was localized in discrete layers in hippocampus regio superior and in area dentata. The highest activity in hippocampus was found in a narrow infrapyramidal zone, but high activities were also observed in the rest of stratum oriens and in stratum pyramidale. In area dentata the highest activities were found in a narrow supragranular zone and in hilus fasciae dentatae. The localization corresponded very closely to that of acetylcholinesterase. The main part of ChAc activity was confined to the synaptosome fraction. The results are compatible with the view that pyramidal and granular cells are excited by cholinergic boutons, mainly located on the basal or apical dendrites near the somata.
