The role of apoE in the CNS is not well established. No neurological effects have been noted in human apoE-deficient subjects, and apoE-deficient mice have no developmental by: The human apoB transgenic mice were crossed with a previously described line of transgenic mice expressing human apo(a) cDNA 2.
The resulting combined transgenic animals expressing both human apoB and human apo(a) produced an Lp(a) particle sharing many properties with Lp(a) present in the plasma of : Edward M. Rubin. Apolipoprotein E (apoE) functions as an important carrier protein in the redistribution of lipids among cells (1).
The brain is second only to the liver with respect to apoE expression levels, and evidence has been accumulating rapidly that apoE plays a critical role in central nervous system (CNS) integrity, function, and repair after injury (2–5).Cited by: Here we show that transgenic mice expressing human apolipoprotein(a) are more susceptible than control mice to the development of lipid-staining lesions in the aorta, and that apolipoprotein(a).

In the central nervous system, apoE is synthesized by glial cells and neurons, but it is unclear whether the cellular source affects its biological activities. To address this issue, we induced excitotoxic injury by systemic kainic acid injection in transgenic Apoe knockout mice expressing human apoE isoforms in astrocytes or neurons.
Regardless of its cellular source, apoE3 expression protected neuronal synapses and dendrites against the excitotoxicity seen in apoE-deficient Cited by: Apolipoprotein E (APOE) is a member of the lipoprotein family of cholesterol transporters.
Within the central nervous system (CNS), it mediates functions that are critical for neuronal development, plasticity, and repair [48,49]. The three most prevalent APOE isoforms are differentially encoded by the APOE ε2, ε3, and ε4 allele variants .
Even more common are the problems of aging which are not due to disease but to more subtle impairments in neurobiological systems, including impairments in vision, memory loss, muscle weakening, and loss of reproductive functions, changes in body weight, and sleeplessness.
Transgenic mice (Tg) overexpressing human apolipoprotein D (H-apoD) in the brain are resistant to neurodegeneration.
Despite the use of a neuron-specific promoter to generate the Tg. The rats were produced by microinjection of a 13 kbp DNA fragment containing the human apolipoprotein A-I gene plus 10 kbp of its 5′ flanking sequence and 1 kbp of its 3′ flanking sequence.

Type III hyperlipoproteinemia (HLP) is a genetic disorder of lipid metabolism in humans in which the primary molecular defect is a mutation(s) in apolipoprotein (apo) E that causes defective interaction of apoE with lipoprotein receptors and an accumulation of cholesterol-rich β-VLDL in the blood (Mahley and Rall, ).Author: Stanley C.

Introduction. Human apolipoprotein E (ApoE) is located on chromosome 19 and encodes a 35 kDa glycoprotein  that exists in three isoforms: E2, E3 and E4 [2,3].These isoforms differ by amino acid substitutions at two positions (residues and ) .The amino acid changes are believed to alter the protein charge and stability , thereby contributing to its distinctive.
