Effects of vitamin A and D receptor gene polymorphisms/haplotypes on immune responses to measles vaccine.

ABSTRACT: Vitamins A and D, and their receptors, are important regulators of the immune system, including vaccine immune response. We assessed the association between polymorphisms in the vitamin A receptors [retinoic acid receptor ?, retinoic acid receptor ? (RARB), and retinoic acid receptor ?] and vitamin D receptor (VDR)/retinoid X receptor ? (RXRA) genes and interindividual variations in immune responses after two doses of measles vaccine in 745 children.Using a tag single nucleotide polymorphism (SNP) approach, we genotyped 745 healthy children for the 391 polymorphisms in vitamin A receptor and VDR genes.The RARB haplotype (rs6800566/rs6550976/rs9834818) was significantly associated with variations in both measles antibody (global, P=0.013) and cytokine secretion levels, such as interleukin (IL)-10 (global, P=0.006), interferon (IFN)-? (global, P=0.008), and tumor necrosis factor-? (global, P=0.039) in the Caucasian subgroup. Specifically, the RARB haplotype, AAC, was associated with higher (t-statistic: 3.27, P=0.001) measles antibody levels. At the other end of the spectrum, haplotype GG for rs6550978/rs6777544 was associated with lower antibody levels (t-statistic: -2.32, P=0.020) in the Caucasian subgroup. In a sensitivity analysis, the RARB haplotype, CTGGGCAA, remained marginally significant (P<0.02) when the single SNP rs12630816 was included in the model for IL-10 secretion levels. A significant association was found between lower measles-specific IFN-? Enzyme-linked immunosorbent spot responses and haplotypes rs11102986/rs11103473/rs11103482/rs10776909/rs12004589/rs35780541/rs2266677/rs875444 (global, P=0.004) and rs6537944/rs3118571 (global, P<0.001) in the RXRA gene for Caucasians. We also found associations between multiple RARB, VDR, and RXRA SNPs/haplotypes and measles-specific IL-2, IL-6, IL-10, IFN-?, IFN-?, IFN?-1, and TNF-? cytokine secretions.Our results suggest that specific allelic variations and haplotypes in the vitamin A receptor and VDR genes may influence adaptive immune responses to measles vaccine.

<h4>Objective</h4>Vitamins A and D, and their receptors, are important regulators of the immune system, including vaccine immune response. We assessed the association between polymorphisms in the vitamin A receptors [retinoic acid receptor α, retinoic acid receptor β (RARB), and retinoic acid receptor γ] and vitamin D receptor (VDR)/retinoid X receptor α (RXRA) genes and interindividual variations in immune responses after two doses of measles vaccine in 745 children.<h4>Methods</h4>Using a tag ...[more]

Project description:IntroductionVitamin D receptor (VDR) genotypes may influence breast cancer risk by altering potential anticarcinogenic effects of vitamin D, but epidemiological studies have been inconsistent. Effect modification by serum 25-hydroxyvitamin D (25 [OH]D), the biomarker for vitamin D status in humans, has rarely been examined.MethodsWe assessed the effects of two frequently analyzed polymorphisms (FokI and TaqI) and two potentially functional variants (VDR-5132 and Cdx2) in the VDR gene, which thus far have not been analyzed with respect to breast cancer risk, on postmenopausal breast cancer risk in a population-based, case-control study including 1,408 patients (cases) and 2,612 control individuals (controls) matched for year of birth. Odds ratios (ORs) for breast cancer adjusted for potential confounders were calculated for genotypes and estimated haplotypes.ResultsNo differences in serum 25(OD)D concentrations by VDR genotype were observed. None of the analyzed polymorphisms was associated with overall risk for postmenopausal breast cancer. However, the TaqI polymorphism was associated with a significantly increased risk for oestrogen receptor positive tumours (OR = 1.18, 95% confidence interval [CI] = 1.00 to 1.38, comparing t allele carriers with noncarriers) but not for oestrogen receptor negative tumours (OR = 0.88, 95% CI = 0.69 to 1.13; P for interaction = 0.04). Haplotype analysis revealed the haplotype FtCA (FokI F, TaqI t, VDR-5132 C, Cdx2 A), which contains the TaqI t allele, to be associated with a significantly greater breast cancer risk as compared with the most frequent haplotype FTCG (OR = 1.43, 95% CI = 1.00 to 2.05). No significant interaction between VDR genotypes or haplotypes and 25(OH)D was observed.ConclusionOur results support potential effects of VDR polymorphisms on postmenopausal breast cancer risk and possible differential effects of receptor status of the tumour. However, further studies focusing on the influence of polymorphisms and haplotypes on VDR functionality, activity and concentration are needed.

Project description:Mumps outbreaks continue to occur throughout the world, including in highly vaccinated populations. Vaccination against mumps has been successful; however, humoral and cellular immune responses to mumps vaccines vary significantly from person to person. We set out to assess whether HLA and cytokine gene polymorphisms are associated with variations in the immune response to mumps viral vaccine.To identify genetic factors that might contribute to variations in mumps vaccine-induced immune responses, we performed HLA genotyping in a group of 346 healthy schoolchildren (12-18 years of age) who previously received 2 doses of live mumps vaccine. Single-nucleotide polymorphisms (minor allele frequency of >5%) in cytokine and cytokine receptor genes were genotyped for a subset of 118 children.Median values for mumps-specific antibody titers and lymphoproliferative stimulation indices were 729 IU/mL and 4.8, respectively. Girls demonstrated significantly higher mumps antibody titers than boys, indicating gender-linked genetic differences in humoral immune response. Significant associations were found between the HLA-DQB1*0303 alleles and lower mumps-specific antibody titers. An interesting finding was the association of several HLA class II alleles with mumps-specific lymphoproliferation. Alleles of the DRB1 (*0101, *0301, *0801, *1001, *1201, and *1302), DQA1 (*0101, *0105, *0401, and *0501), and DQB1 (*0201, *0402, and *0501) loci were associated with significant variations in lymphoproliferative immune responses to mumps vaccine. Additional associations were observed with single-nucleotide polymorphisms in the interleukin-10RA, interleukin-12RB1, and interleukin-12RB2 cytokine receptor genes. Minor alleles for 4 single-nucleotide polymorphisms within interleukin-10RA and interleukin-12RB genes were associated with variations in humoral and cellular immune responses to mumps vaccination.These data suggest the important role of HLA and immunoregulatory cytokine receptor gene polymorphisms in explaining variations in mumps vaccine-induced immune responses.
