    Abstract:
    BACKGROUND AND OBJECTIVE: Cell activation through toll-like receptors (TLRs) has robust bipolar effects on host immunity and the pathogenesis of asthma. The TLR2 subfamily is a pivotal member of the TLR family. We sought to determine whether mutations in TLR2 subfamily genes affect the risk of asthma. METHODS: A total of 318 asthmatic patients and 352 nonasthmatic controls were recruited. Eight single-nucleotide polymorphisms in TLR2 subfamily genes were detected using GenomeLab SNPstream (Beckman Coulter, Fullerton, California, USA). RESULTS: We found that patients with the TLR2/rs7656411 TT variant homozygote had a significantly reduced risk of asthma when compared with those with the GG wild-type homozygote (adjusted odds ratio [OR], 0.63; 95% confidence interval (CI], 0.41-0.98; P = .036). Furthermore, a positive association was observed between the T allele of rs2381289 in TLR6 and allergic rhinitis in asthma (OR, 1.79; 95% CI, 1.10-2.91; P = .025), while the A allele of rs11466651 in TLRIO was negatively associated with allergic rhinitis (OR, 0.49; 95% CI, 0.26-0.95; P = .046). CONCLUSION: Our results indicate that a genetic variant in the TLR2 subfamily may play a role in susceptibility to asthma.
