A major and the second most common isoform of apolipoprotein E. In humans, Apo E4 differs from APOLIPOPROTEIN E3 at only one residue 112 (cysteine is replaced by arginine), and exhibits a lower resistance to denaturation and greater propensity to form folded intermediates. Apo E4 is a risk factor for ALZHEIMER DISEASE and CARDIOVASCULAR DISEASES.

Apolipoprotein E4 (apoE4), the most prevalent genetic risk factor of AD, is expressed in more than half of AD patients and is thus an important possible AD therapeutic target. Apolipoproteins are proteins that bind lipids (oil-soluble substances such as fat and cholesterol) to form lipoproteins. They transport lipids (and fat soluble vitamins) in blood, cerebrospinal fluid and lymph. The lipid components of lipoproteins are insoluble in water. Die Isoform E4 kann bei heterozygotem Vorliegen zur Entwicklung einer Typ V-Hyperlipidämie führen.

The APOE gene is involved in making a protein that helps carry cholesterol and other types of fat in the bloodstream. APOE comes in several different forms, or alleles. 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. 2018-11-27 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. Mohamed Raâfet Ben Khedher.

The apolipoprotein E4 (E4) allele is present worldwide, despite its associations with higher risk of cardiovascular morbidity, accelerated cognitive decline during aging, and Alzheimer's disease (AD). The E4 allele is especially prevalent in some tropical regions with a high parasite burden. Mahley, R.W. and Y. Huang, Small-molecule structure correctors target abnormal protein structure and function: structure corrector rescue of apolipoprotein E4-associated neuropathology.

Apolipoprotein E4 (apoE4), the most prevalent genetic risk factor of AD, is expressed in more than half of AD patients and is thus an important possible AD therapeutic target.

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.
