Comparing 2 hypotheses side-by-side
## Mechanistic Overview The Glial Ketone Metabolic Shunt Hypothesis starts from the claim that modulating HMGCS2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "The Glial Ketone Metabolic Shunt Hypothesis proposes that reactive astrocytes in neurodegenerative disease aberrantly upregulate ketone body synthesis (ketogenesis), creating a metabolic steal syndrome that depletes shared glucose and lipid substrates from neurons
## 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.
