In situ hybridization of nucleus basalis neurons shows increased. beta. -amyloid mRNA in Alzheimer disease
To determine which cells within the brain produce ..beta..-amyloid mRNA and to assess expression of the ..beta..-amyloid gene in Alzheimer disease, the authors analyzed brain tissue from Alzheimer and control patients by in situ hybridization. The results demonstrate that ..beta..-amyloid mRNA is produced by neurons in the nucleus basalis of Meynert and cerebral cortex and that nuclues basalis perikarya from Alzheimer patients consistently hybridize more ..beta..-amyloid probe than those from controls. These observations support the hypothesis that increased expression of the ..beta..-amyloid gene plays an important role in the deposition of amyloid in the brains of patients with Alzheimer disease.
