Disrupted energy metabolism, in particular reduced activity of cytochrome oxidase (EC, alpha-ketoglutarate dehydrogenase (EC and pyruvate dehydrogenase (EC have been reported in post-mortem Alzheimer's disease brain. beta-Amyloid is strongly implicated in Alzheimer's pathology and can be formed intracellularly in neurones. We have(More)
Beta-amyloid deposition and compromised energy metabolism both occur in vulnerable brain regions in Alzheimer's disease. It is not known whether beta-amyloid is the cause of impairment of energy metabolism, nor whether impaired energy metabolism is specific to neurons. Our results, using primary neuronal cultures, show that 24-h incubation with A(More)
The effects of amyloid-beta peptide (Aβ) on astrocyte responses to activation of mGlu5 receptors have been investigated using calcium imaging. Pre-incubation with Aβ1-40 peptide for up to 72 h produced a time- and concentration-dependent 2-4 fold enhancement in the magnitude of the intracellular calcium mobilization response to the group I metabotropic(More)
