The Inner Link between Apolipoprotein E and the risk of Alzheimer’s disease

Abstract

Alzheimer’s disease (AD) is a common neurodegenerative disorder that severely affects the quality of life of the elderly. The APOE gene and its encoded apolipoprotein E (ApoE) play a significant role in the pathogenesis of AD, particularly the APOEε4 allele, which is significantly associated with an increased risk of AD. Current research indicates that different alleles of the APOE gene affect brain development, lipid metabolism, and synaptic function, with ApoE4 being associated with cognitive decline and an increased risk of AD. Moreover, therapeutic strategies targeting the APOE gene, such as gene editing techniques and the development of small molecule drugs, are actively being researched to provide new possibilities for the treatment of AD. Nevertheless, many unknowns remain regarding the specific mechanisms of action of the APOE gene in AD and how to effectively utilize this knowledge to develop treatment methods. This article analyzes the structure and function of the APOE gene and its role in AD, discusses the main drugs and strategies currently used in AD treatment, and proposes the potential for future treatments based on the APOE gene. However, further research and exploration are needed to understand the complex relationship between the APOE gene and AD, as well as the long-term effects and safety of treatment methods. With the advancement of technology, there is hope for the development of more effective and safer AD treatment plans in the future, to improve the quality of life of patients and reduce the societal burden.
