英文摘要

BACKGROUND:

Leprosy patients had a very low risk of Alzheimer's disease (AD), and the β-amyloid (Aβ) deposition was significantly lower in the brain tissues of elderly leprosy patients than those of age-matched controls. The APOE played critical roles in lipid metabolic pathways and in brain to facilitate the proteolytic clearance of Aβ. We hypothesized that APOE would confer risk to leprosy as lipid metabolism was involved in Mycobacterium leprae infection.

OBJECTIVE:

To investigate the potential genetic associations between APOE and leprosy in two independent Chinese case-control cohorts from the Yuxi and Wenshan Prefectures, Yunnan Province of Southwest China.

METHODS:

Five APOE SNPs were analyzed in 1110 individuals (527 patients and 583 controls) from the Yuxi Prefecture by using SNaPshot assay. Genetic variations in the entire APOE exons of were screened in 1788 individuals (798 patients and 990 controls) from the Wenshan Prefecture by using the next generation sequencing technology.

RESULTS:

The AD-associated SNPs rs405509 and rs439401 increased risk to leprosy per se and multibacillary leprosy (MB, P < 0.005), but APOE-ε4 allele did not affect leprosy. SNPs rs405509 and rs439401 were cis eQTLs for APOE expression in human skin. Differential APOE mRNA expression was observed in skin lesions of type I reaction leprosy and MB patients. The APOE and related lipid genes were participated in a highly interacted network with leprosy susceptibility genes.

CONCLUSIONS:

The APOE gene was associated with leprosy, most likely by regulating lipid metabolism related genes. This article is protected by copyright. All rights reserved.

Therefore, the information provided by network analysis might direct future functional experiments to elucidate its potential biological significance in leprosy. In short, we found that APOE SNPs rs405509 and rs439401 were associated with leprosy, and the effect might be mediated by altered APOE mRNA expression and its potential role in lipid metabolic pathways during M. leprae infection. Future studies are needed to validate our current observation and to explore potential function of APOE during leprosy onset and progression.
