This hypothesis proposes that enhancing ketone body synthesis specifically within astrocytes through overexpression of 3-hydroxy-3-methylglutaryl-CoA synthase 2 (HMGCS2) can restore neuronal metabolic homeostasis in neurodegenerative conditions. Unlike the typical hepatic ketogenesis pathway, astrocytes possess latent ketogenic capacity that becomes activated under metabolic stress. By genetically upregulating HMGCS2 in astrocytes using viral vectors or transgenic approaches, we can establish a
## Mechanistic Overview
Ketone Utilization Index as Metabolic Flexibility Biomarker starts from the claim that modulating HMGCS2 within the disease context of translational neuroscience can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview Ketone Utilization Index as Metabolic Flexibility Biomarker starts from the claim that modulating HMGCS2 within the disease context of translational neuroscience can redirect a disease-relevant process. The original
