Epidemiological studies have suggested an inverse relationship between the adipocytokine leptin and the onset of Alzheimer's disease (AD), and leptin supplementation decreases amyloid-β (Aβ) production and tau phosphorylation (p-tau), two major biochemical events that play a key role in the pathogenesis of AD. We have previously shown that the cholesterol oxidized product 27-hydroxycholesterol (27-OHC) inhibits leptin expression, an effect that correlated with increased levels of Aβ and p-tau… CONTINUE READING
