Abstract
- BACKGROUND AND OBJECTIVES
CC chemokine receptor (CCR5) is characteristic of the Th 1 phenotype, the receptor of RANTES, MIP-1alphaand MIP-1beta. The receptor of CCR5 delta32 (a 32 bp deletion in the CCR5 gene, mutant type) results in the production of a non-functional receptor. Given the potential importance of CCR5 in allergic inflammation, we hypothesized that individuals carrying the CCR5 delta32 allele would show a reduced prevalence of allergic rhinitis. SUBJECTS AND METHOD: Blood samples for genetic analysis were obtained from 187 individuals with allergic rhinitis and from 278 healthy subjects without atopic diseases. Polymerase chain reaction-based assay for the CCR5 gene polymorphism was used for genotyping. RESULTS: We could not find the CCR5 delta32 homozygotes and heterozygotes at all in neither of the controls nor allergic rhinitis Korean patients. CONCLUSION: Since the CCR5 delta32 allele frequency did not deviate from that in the healthy control population, it is unlikely that this allele influences predisposition to allergic rhinitis in Koreans.
