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)
Mitochondrial cytochrome oxidase is competitively and reversibly inhibited by inhibitors that bind to ferrous heme, such as carbon monoxide and nitric oxide. In the case of nitric oxide, nanomolar levels inhibit cytochrome oxidase by competing with oxygen at the enzyme's heme-copper active site. This raises the K(m) for cellular respiration into the(More)
