This hypothesis proposes that NAD+ precursor supplementation can restore neuronal ketone body utilization by activating SIRT1-mediated upregulation of MCT1 (monocarboxylate transporter 1). In neurodegenerative conditions, chronic PARP1 activation depletes cellular NAD+ pools, leading to reduced SIRT1 activity and subsequent downregulation of MCT1 expression. This creates a metabolic catastrophe where neurons lose their ability to efficiently transport and utilize ketone bodies as an alternative

In neurodegenerative conditions, chronic PARP1 activation depletes cellular NAD+ pools, leading to reduced SIRT1 activity and subsequent downregulation of MCT1 expression.
