摘要: In every study involving human immune parameters, large inter-subject variability occurs which can make interpretation of results difficult. The aim this was to evaluate whether genetic variants in cytokine receptors could associate with laboratory measures. A total 207 normal volunteers were recruited study. Immunoregulatory profiles measured by flow cytometry and genotyping assays performed allelic discrimination real-time PCR. categorized according various single nucleotide polymorphisms (SNPs) including T-56C G-611A IFN-γ receptor 1 (IFNGR1); Q64R IFNGR2; Ile50Val, Q576R S503P IL4R. Results reveal that Th1 levels significantly higher the heterozygous IFNGR1 polymorphism (minor allele) compared wild-type (WT, major (p = 0.006). For IL4R, Th1/Th2 ratio lower for homozygous SNP (Arg/Arg) WT (Gln/Gln) 0.035). addition, significant interaction effects demographic characteristics on SNP-immune parameter associations reported as well. We conclude might Approach analysis be useful categorizing baseline responses more accurately clinical data.
