Genetic variation in human apoprotein E was studied using the technique of isoelectric focusing applied to delipidated very low density lipoprotein from 426 Christchurch blood donors and 7 patients with type III hyperlipoproteinemia. Six phenotypes were distinguishable by the relative proportions of the apoprotein E isomers. In the blood donors, observed frequencies for these were: E3/3 = 51.4
Apolipoprotein E4–driven effects on inflammatory and neurotrophic factors in peripheral extracellular vesicles from cognitively impaired, no dementia participants who converted to Alzheimer's disease Apolipoprotein E (ApoE) genotype is the strongest genetic risk factor for late‐onset Alzheimer's disease, with the ε4 allele increasing risk in a dose‐dependent fashion. In addition to ApoE4 playing a crucial role in amyloid‐β deposition, recent evidence suggests that it also plays an important role in tau pathology and tau‐mediated neurodegeneration. Apolipoproteïne E (ApoE) is een eiwit klasse die betrokken is bij de vetstofwisseling. ApoE speelt een belangrijke rol in de ziekte van Alzheimer en hart- en vaatziekten.

Population frequencies for these apoE alleles are: E2 (15%) Apolipoprotein E4 (apoE4) is the most prevalent genetic risk factor for Alzheimer's disease. We utilized apoE4‐targeted replacement mice (approved by the Tel Aviv University Animal Care Committee) to investigate whether cholinergic dysfunction, which increases during aging and is a hallmark of Alzheimer's disease, is accentuated by apoE4. Defects in apolipoprotein E (Apo E) are responsible for familial dysbetalipoproteinemia, or type III hyperlipoproteinemia, in which increased plasma cholesterol and triglycerides result from impaired clearance of chylomicron and very-low-density lipoprotein (VLDL) remnants. The human APOE gene is located on chromosome 19. Greenberg et al. (1995) found that the presence of apolipoprotein E4 significantly increased the odds ratio for moderate or severe cerebral amyloid angiopathy (CAA; see 605714), even after controlling for the presence of Alzheimer disease.

In most clinical studies, apoE4 carriers account for 65-80% of all AD cases, highlighting the importance of apoE4 in AD pathogenesis. Emerging data suggest that apoE4, with its multiple cellular origins and multiple structural and biophysical properties, The apolipoprotein E4 (ApoE4) genotype is a major risk factor for late-onset sporadic AD. Alterations in miRNAs and cognitive decline are expected in humans with the ApoE4 genotype—mainly because the ApoE4 status increases the production of Aβ. Several lines of evidence support this notion. Apolipoprotein (apo) E4 is the major genetic risk factor for Alzheimer's disease (AD), increasing risk and decreasing age of disease onset. Many studies have demonstrated the detrimental effects of apoE4 in varying cellular contexts. However, the underlying mechanisms explaining how apoE4 leads to cognitive decline are not fully understood. Apolipoprotein E4 is a member of the apolipoprotein E family of plasma lipoproteins that bind reversibly with lipoprotein and play an important role in lipid metabolism. ApoE4 regulates plasma lipid levels by increasing the degradation of particles rich in triglycerides and cholesterol.
APOE e4 has been associated with an increased risk of late onset Alzheimer's disease (AD), that is AD that develops after the age of 65. People who have one copy of e4 (e2/e4 or e3/e4) carry some increased risk and people with two copies of e4 (e4/e4) are associated with even more of a risk of developing AD.
