Mechanistic description
Restoration of Neuronal Ketone Body Utilization via MCT1 Upregulation
Mechanism / pathway
- SLC16A1 (MCT1)
- metabolomics
Evidence for (4)
Human AD prefrontal cortex shows 40-60% reduction in MCT1 and MCT4 protein expression compared to age-matched controls
Ketogenic diet intervention in MCI patients improves cognitive outcomes and increases serum ketone bodies
Mouse model of AD (APP/PS1) demonstrates that ketone supplementation improves mitochondrial function only when MCT expression is preserved
CSF β-hydroxybutyrate levels correlate inversely with dementia severity
Evidence against (4)
Ketogenic diets show limited CNS ketone uptake in humans - using 11C-acetoacetate PET, ketones enter brain but uptake saturates at physiological levels
Clinical trials of ketone esters in AD show modest brain uptake - cerebral metabolic improvement is limited
MCT1 has bidirectional transport function - upregulation could increase lactate efflux from neurons, potentially worsening energy balance
APP/PS1 mouse models may not recapitulate human AD ketone metabolism - species differences in MCT expression patterns are significant
