Abstract

Introduction

Previous studies have found associations between polymorphisms in some candidate genes and chronic obstructive pulmonary disease (COPD) risk. However, the association between TLR2 and TLR9 polymorphisms and COPD risk remains uncertain.

Methods

Four variants (rs352140, rs3804099, rs3804100, and rs5743705) of the TLR2 and TLR9 genes in 540 COPD patients and 507 healthy controls were genotyped using the Agena MassARRAY system. Odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the association of TLR2 and TLR9 polymorphisms with COPD risk by logistic regression analysis.

Results

TLR9-rs352140, TLR2-rs3804100, and TLR2-rs5743705 were related to a lower risk of COPD among Chinese people and the significance still existed after Bonferroni correction. Additionally, rs3804099, rs3804100, and rs352140 were found to be associated with COPD development in different subgroups (males, age ≤ 68 years, smokers, BMI < 24 kg/m², and acute exacerbation).

Conclusions

Our findings indicated that TLR9 and TLR2 polymorphisms had protective effects on the development of COPD among Chinese people.

TLR2和TLR9基因的同义突变降低了中国汉族人群对慢性阻塞性肺病的易感性

导言以往的研究发现，一些候选基因的多态性与慢性阻塞性肺病（COPD）风险之间存在关联。方法使用 Agena MassARRAY 系统对 540 名慢性阻塞性肺病患者和 507 名健康对照者的 TLR2 和 TLR9 基因的四个变体（rs352140、rs3804099、rs3804100 和 rs5743705）进行基因分型。结果 TLR9-rs352140、TLR2-rs3804100和TLR2-rs5743705与中国人患慢性阻塞性肺病的风险较低有关，且经Bonferroni校正后仍有显著性。此外，rs3804099、rs3804100 和 rs352140 与不同亚组（男性、年龄小于 68 岁、吸烟者、体重指数为 24 kg/m2、急性加重）的慢性阻塞性肺病发病相关。
