  • Abstract
  • Look Inside

This study aimed to provide clear data on the localization of the mRNA for the amyloid precursor protein (APP) in human brain. It is known to occur in neurons but the possible localization in other type of brain, cells is controversial among several authors. A cDNA probe constructed by polymerase chain reaction for APP, which was not specific for a particular isoform, gave punctate staining and showed a clear localization not only in neurons but in astrocytes in all brains,, as well as in the reactive microglia associated with senile plaques in Alz-heimer disease. A cRNA probe gave more diffuse staining of neurons and giia.
