품종 계통 설명
Apolipoprotein E ε2 (APOE2) is one of the three major human APOE isoforms, characterized by the amino acid signature Cys112/Cys158. The APOE gene is primarily expressed in the liver and central nervous system, where it is synthesized by hepatocytes and astrocytes to encode a 299-amino acid glycoprotein [1]. As a key ligand for the low-density lipoprotein (LDL) receptor family, APOE plays a critical role in cholesterol and triglyceride transport, lipoprotein metabolism, neuronal membrane repair, and the maintenance of synaptic plasticity [1-2]. Compared to APOE3, APOE2 exhibits significantly reduced binding affinity for LDL receptors, which impairs lipid clearance efficiency. Under specific genetic backgrounds, the APOE2 homozygous state can lead to Familial Dysbetalipoproteinemia (Type III Hyperlipoproteinemia) [2]. Furthermore, in contrast to APOE4, APOE2 is generally considered to possess neuroprotective properties and is associated with a reduced risk of Alzheimer's disease (AD) [3].
The huAPOE2 mouse is a humanized model generated via gene editing. The exons 2-4 plus partial flanking sequences of the mouse Apoe gene were replaced with the human APOE gene sequence including exons 2-4 and some downstream sequence of 3'UTR. The point mutation p.R176C (CGC to TGC) was introduced into the human APOE exon 4. This model is suitable for studying dyslipidemia, atherosclerosis, Type III hyperlipoproteinemia, neuroinflammation, Alzheimer's disease (AD), and other APOE2-associated disorders.
