Alzheimer’s disease (AD) is increasingly recognized as a complex neurodegenerative disease beginning decades prior to the cognitive decline. While cognitive deficits remain the cardinal manifestation of AD, metabolic and non-cognitive abnormalities, such as alterations in body weight and neuroendocrine functions, are also present, often preceding the cognitive decline. Furthermore, hypothalamic dysfunction...
Acetate is activated to acetyl-CoA by acetyl-CoA synthetase 2 (AceCS2), a mitochondrial enzyme. Here, we report that the activation of acetate by AceCS2 has a specific and unique role in thermogenesis during fasting. In the skeletal muscle of fasted AceCS2 −/− mice, ATP levels were reduced by 50% compared to AceCS2 +/+ mice. Fasted AceCS2 −/− mice were significantly hypothermic...
