CD14 -550 C/T, which is related to the serum level of soluble CD14, is associated with the development of respiratory syncytial virus bronchiolitis in the Japanese population.

@article{citeulike:2901616, abstract = {BACKGROUND: The contribution that genetic polymorphisms of Toll-like receptor (TLR) 4 and of CD14--both of which recognize respiratory syncytial virus (RSV) in the innate immune response--make to RSV bronchiolitis in the Japanese population has not yet been clarified. METHODS: This study genotyped 2 TLR4 mutations, Asp299Gly and Thr399Ile, and 2 single-nucleotide polymorphisms (SNPs) of CD14, -550 C/T and -159 C/T, in 54 children with RSV bronchiolitis and in 203 control subjects. CD14 SNPs and the serum level of soluble CD14 (sCD14) also were examined in 67 cord-blood specimens and in serum samples from 73 6-year-old children. RESULTS: No TLR4 mutations were found. The frequencies of both the CC genotype and the C allele of CD14 -550 C/T were significantly higher in children with RSV bronchiolitis than in the control subjects. The serum level of sCD14 was significantly higher in children with the CC genotype of CD14 -550 C/T than in those with the CT and TT genotypes. CONCLUSIONS: CD14 -550 C/T, which is related to the serum level of sCD14, is associated with the development of RSV bronchiolitis in the Japanese population.
