Among the earliest changes to occur in Alzheimer’s disease, metabolic dysfunction and chronic neuroinflammation are now known to be major driving forces in disease progression. The paradigm of ‘immunometabolism’ seeks to bridge these two facets, positing that metabolic transformations are indispensable in determining the response of immune cells, such as microglia – the brain’s resident immune population. Proinflammatory stimulation of microglia leads to a shift away from mitochondrial respiration towards a dramatic upregulation of the glycolysis pathway for energy production. This glycolytic burst provides microglia with a rapid supply of ATP, but comes at a cost, as utilizing glucose to …
