Abstract

Toll-like receptors (TLRs) and their intracellular signaling molecules play an important role in innate immunity.In this study, we examined associations between polymorphisms in TLR family genes and measles vaccinespeciWc immune responses. We genotyped 764 subjects (11-22 years old) after two doses of measles vaccine for TLR signaling SNP markers (n = 454). The major alleles of coding SNPs in the TLR2 (rs3804100) and TLR4 (rs5030710) genes were associated with a dose-related increase (660 vs. 892 mIU/ml, p = 0.002) and a doserelated decrease (2,209 vs. 830 mIU/ml, p = 0.001) in measles-speciWc antibodies, respectively. A signiWcant association was found between lower measles antibody levels and the haplotype ACGGCGAGAAAAGAGAAG AGAGAGAA (p = 0.01) in the MAP3K7 gene. Furthermore, the minor allele of a SNP (rs702966) of the KIAA1542 (IRF7) gene was associated with a dose-related decrease in IFN-γ Elispot responses (38 vs. 26 spot-forming cells per 2 × 105 PBMCs, p = 0.00002). We observed an additional 12 associations (p < 0.01) between coding (nonsynonymous and synonymous) polymorphisms within the TLRs (TLR2, 7, and 8), IKBKE, TICAM1, NFKBIA, IRAK2, and KIAA1542 genes and variations in measlesspeciWc IL-2, IL-6, IFN-α, IFN-γ, IFNλ-1, and TNF-α secretion levels. Our data demonstrate that polymorphisms in TLR and other related immune response signaling molecules have signiWcant eVects on measles vaccine-associated immune responses. These data help to establish the genetic foundation for immune response variation in response to measles immunization and provide important insights for the rational development of new measles vaccines.
