Significance The accumulation of amyloid β (Aβ) in the brain appears to be a necessary event in the pathogenesis of Alzheimer’s disease (AD). However, processes linked to the endogenous regulation of Aβ production are still not completely understood. Here, the authors show that Aβ accumulation in neurons is tightly regulated by cholesterol synthesis and apoE transport from astrocytes. The study provides a molecular context for understanding the endogenous regulation of Aβ accumulation and why… 

Beta-amyloid production in neurons is regulated by astrocyte-derived cholesterol

It is shown that Aβ accumulation in neurons is tightly regulated by cholesterol production in astrocytes, which paves the way for future work that will establish whether the selective removal of Aβ by targeting this mechanism has therapeutic potential.

Neuroprotective Effects of Resveratrol by Modifying Cholesterol Metabolism and Aβ Processing in SAMP8 Mice

Age is a prominent factor for cholesterol metabolism dysregulation in the brain of SAMP8 mice and influences the protective effects of RSV through cholesterol metabolism and Aβ processing.

Functional and Phenotypic Diversity of Microglia: Implication for Microglia-Based Therapies for Alzheimer’s Disease

Current understandings of the functional roles of age-dependent microglial activation and neuroinflammation in the pathogenesis of AD are summarized and exponential growth in transcriptomic data provides a solid foundation for in silico drug screening and gains further insight into the development of microglia-based therapeutic interventions for AD.

Silencing of ApoE with Divalent siRNAs Drives Activation of Immune Clearance Pathways and Improves Amyloid Pathology in Mouse Models of Alzheimer’s Disease

Silencing brain ApoE in AD mice significantly reduced amyloid plaque formation without affecting systemic cholesterol levels, confirming that brain and liver APOE pools are spatially and functionally distinct.

Does the imbalance in the apolipoprotein E isoforms underlie the pathophysiological process of sporadic Alzheimer's disease?

A comprehensive interpretation of APoe-mediated effects within AD pathophysiology is proposed, describing some specific cellular, biochemical, and epigenetic mechanisms and updating the different APOE-targeting approaches being developed as potential AD therapies.

Effects of APOE4 allelic dosage on lipidomic signatures in the entorhinal cortex of aged mice

The results suggest that APOE4 expression differentially modulates regional neuronal lipid signatures, which may underlie the increased susceptibility of EC-localized neurons to AD pathology.

Effect of Cholesterol Molecules on Aβ1-42 Wild-Type and Mutants Trimers

It is proposed that cholesterol acts as a glue to speed up the formation of larger aggregates; this provides a mechanistic link between cholesterol and Alzheimer’s disease.

Apolipoprotein E ε4 Mediates Myelin Breakdown by Targeting Oligodendrocytes in Sporadic Alzheimer Disease.

The findings suggest that the disruption of myelination in APOE4 carriers may represent a direct OL pathology, rather than an indirect consequence of amyloid plaque formation or neuronal loss.

Cholesterol and Alzheimer’s Disease; From Risk Genes to Pathological Effects

The different systems that maintain brain cholesterol metabolism in the healthy brain are discussed, and how dysregulation of these processes can lead, or contribute to, Alzheimer’s disease.

Regulation of astrocyte lipid metabolism and ApoE secretion by the microglial oxysterol, 25-hydroxycholesterol

It is shown that astrocytes take up externally added 25HC and respond with altered lipid metabolism, and a doubling of the amount of cholesterol esters and their concomitant storage in lipid droplets is shown.



Alzheimer's disease: the cholesterol connection

The identification of a variant of the apolipoprotein E (APOE) gene as a major genetic risk factor for AD is also consistent with a role for cholesterol in the pathogenesis of AD.

Amyloid-β-independent regulators of tau pathology in Alzheimer disease

Novel insights from preclinical research are outlined that implicate apolipoprotein E, the endocytic system, cholesterol metabolism and microglial activation as Aβ-independent regulators of tau pathology in Alzheimer disease.

The amyloid hypothesis of Alzheimer's disease at 25 years

Although many factors contribute to AD pathogenesis, Aβ dyshomeostasis has emerged as the most extensively validated and compelling therapeutic target.

The link between altered cholesterol metabolism and Alzheimer's disease

Growing evidence supports the idea that cholesterol oxidation products, known as oxysterols, may be the missing link between altered brain cholesterol metabolism and AD pathogenesis, as their involvement in neurotoxicity, mainly by interacting with Aβ peptides, is reported.

The involvement of lipid rafts in Alzheimer's disease (Review)

Evidence suggests that amyloidogenic APP processing may preferentially occur in the cholesterol-rich regions of membranes known as lipid rafts, and that changes in cholesterol levels could exert their effects by altering the distribution of APP-cleaving enzymes within the membrane.

Amyloidogenic processing of the Alzheimer β-amyloid precursor protein depends on lipid rafts

It is demonstrated that lipid rafts are critically involved in regulating Aβ generation and the existence of two APP pools is suggested, although APP inside raft clusters seems to be cleaved by β-secretase, APP outside rafts undergoes cleavage by α- secretase.

Alzheimer's Amyloid-β is an Antimicrobial Peptide: A Review of the Evidence.

The antimicrobial role of Aβ may explain why increased rates of infection have been observed in some of the AD clinical trials that depleted Aβ, and progress toward a cure for AD will accelerate once treatment strategies begin to take into account the likely physiological functions of this enigmatic peptide.
