摘要：

Background: NLR family, pyrin domain containing 3 (NLRP3), controls the activity of inflammatory caspase-1 by forming inflammasomes, which leads to cleavage of the procytokines IL-1 beta and IL-18. Recent studies have shown associations of human NLRP3 polymorphisms with susceptibility to various inflammatory diseases; however, the association with allergic diseases remains unclear. Objective: We sought to examine whether NLRP3 polymorphisms are associated with susceptibility to food allergy, food-induced anaphylaxis, and aspirin-induced asthma (AIA). Methods: We selected 15 tag single nucleotide polymorphisms (SNPs) of NLRP3 and conducted association analyses of NLRP3 using 574 and 1279 samples for food allergy and AIA, respectively. We further performed functional analyses of the susceptible SNPs. Results: Two NLRP3 SNPs (rs4612666 and rs10754558) were significantly associated with susceptibility to food-induced anaphylaxis (P = .00086 and P = .00068, respectively). The NLRP3 haplotype of the 2 SNPs also showed a significant association (P = .000098). We could confirm the association with susceptibility to another hypersensitivity phenotype, AIA (rs4612666, P = .0096). Functional analysis revealed that the risk alleles of rs4612666 and rs10754558 increased the enhancer activity of NLRP3 expression and NLRP3 mRNA stability, respectively. Conclusion: Our results indicate that the NLRP3 SNPs might play an important role in the development of food-induced anaphylaxis and AIA in a gain-of-function manner. Further research on the NLRP3 inflammasome will contribute to the development of novel diagnostic and therapeutic methods for food-induced anaphylaxis and AIA.
