Topic: alpha-ketoglutarate dehydrogenase complex

Alzheimer's disease (AD) is a major neurodegenerative disease characterized by a marked decline in the activity of the alpha-ketoglutarate dehydrogenase complex (AKGDHC), a key metabolite of the tricarboxylic acid (TCA) cycle. Earlier studies have shown that the calcium salt of AKG, CaAKG, increases the healthspan and lifespan in C57BL/6 mice by reducing inflammatory cytokines. Here, we demonstrate that CaAKG attenuates long-term potentiation (LTP) in an animal model of AD, APP/PS1 mice. CaAKG application during strong tetanisation converts early-LTP to late-LTP, stable for 4 hours in the CA1
