General and dramatic glial reaction in Alzheimer brains
Delacourte A.. Neurology, 1990-01-01
Topic: Amyloid, tau and blood-test diagnosis
We quantified glial fibrillary acidic protein (GFAP) using immunoblot techniques and anti-GFAP, in unfractionated homogenates of different brain regions from Alzheimer's disease (AD) patients. The amount of GFAP was significantly higher than in brains from controls and other neurodegenerative disorders (mean of 11 times), even in brain regions usually free of AD lesions such as caudate nucleus, thalamus, cerebellum, or brainstem. This dramatic increase of GFAP is not simply reflective of the astrocytic gliosis usually observed near the neurofibrillary tangles and senile plaques but more likely represents an astrocytic reaction in the whole brain corresponding to an overproduction or an accumulation of GFAP. The significance of such an increase is unknown, but it might be a key element in the pathogenesis of AD.
Key findings
- The amount of GFAP was significantly higher than in brains from controls and other neurodegenerative disorders (mean of 11 times), even in brain regions usually free of AD lesions such as caudate nucleus, thalamus, cerebellum, or brainstem.
Why it matters
GFAP levels were on average 11 times higher in brain regions from Alzheimer patients than in controls, including regions usually free of Alzheimer lesions. The significance of this increase is unknown, and no treatment, cure or prevention is reported.
