1. Dietary high cholesterol and trace metals in the drinking water increase levels of ABCA1 in the rabbit hippocampus and temporal cortex.

    Journal of Alzheimer's Disease 49(1):201 (2015) PMID 26444796 PMCID PMC4643214

    Cholesterol-fed rabbits have been documented to show increased amyloid-β (Aβ) deposits in the brain that can be exacerbated by the quality of drinking water especially if rabbits drink tap water or distilled water containing copper. One mechanism of cholesterol and Aβ clearance may be through th...
  2. KIF6 719Arg allele is associated with statin effects on cholesterol levels in amnestic mild cognitive impairment and Alzheimer's disease patients.

    Journal of Alzheimer's Disease 33(1):111 (2013) PMID 22914592 PMCID PMC3731451

    KIF6 719Arg allele carriers are thought to have a greater lipid lowering response from statin therapy than non-carriers. Given the continued interest in the relationship between cholesterol, statin use, amnestic mild cognitive impairment (aMCI), and Alzheimer's disease (AD), investigating the ro...

    To test the hypothesis that narrowing of cranial blood vessels in cholesterol-fed rabbits is a function of the duration of the high cholesterol diet. Such neurovascular changes, caused by elevated serum cholesterol, are linked to stroke and Alzheimer's disease risk. Four groups of New Zealand Wh...
  10. Cholesterol and cognitive performance in normal controls and the influence of elective statin use after conversion to mild cognitive impairment: results in a clinical trial cohort.

    Neurodegenerative Diseases 7(1-3):183 (2010) PMID 20224282 PMCID PMC2859238

    We reported a significant 67% reduction in the hazard risk of incident Alzheimer's disease (AD) with elective statin use in the AD Anti-inflammatory Prevention Trial (ADAPT), without a reduction in risk of incident mild cognitive impairment (MCI). To assess if cholesterol levels are associated w...

  17. Cholesterol enhances classical conditioning of the rabbit heart rate response.

    Behavioural Brain Research 181(1):52 (2007) PMID 17466388 PMCID PMC1942042

  18. Cholesterol metabolism and brain amyloidosis: evidence for a role of copper in the clearance of Abeta through the liver.

    Current Alzheimer Research 4(2):165 (2007) PMID 17430242

    Mounting evidence suggests that copper may influence the progression of Alzheimer's disease by reducing clearance of the amyloid beta protein (Ass) from the brain. We propose that Abeta is cleared from the brain by tagging along with cholesterol/ApoE in traversing the BBB, with subsequent incorp...
