Individual genetic variations within the DEFB1 gene, encoding for hBD-1, could influence gene expression and protein production.&lt;/p&gt;&lt;p&gt;&lt;b&gt;DESIGN: &lt;/b&gt;Three DEFB1 polymorphisms at 5' untranslated region (UTR), -52G &gt; A (rs1799946), -44C &gt; G (rs1800972) and -20G &gt; A (rs11362), and two polymorphisms at DEFB1 3' UTR, c*5G &gt; A (rs1047031) and c*87A &gt; G (rs1800971), were analysed by direct sequencing and correlated with hDB-1 salivary concentration (tested with enzyme-linked immunosorbent assay (ELISA)) in 40 healthy subjects.&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS: &lt;/b&gt;Significant associations were found between individuals presenting different DEFB1 polymorphisms at positions -52 and -44 of the gene and hBD-1 salivary concentrations: -52 G/G carriers had higher levels of protein than G/A and A/A; -44C/G subjects showed a higher protein concentration than homozygous wild-type C/C. For the -20G &gt; A, c*5G &gt; A and c*87A &gt; G polymorphisms, no statistically significant differences were found. Combined haplotype analysis confirmed the results obtained considering the single-nucleotide polymorphisms (SNPs) singularly.&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSION: &lt;/b&gt;Polymorphisms in the DEFB1 gene influence hBD-1 production and, therefore, could modify the innate immune system responses and, consequently, the oral health.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/25939140?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Zupin, Luisa</style></author><author><style face="normal" font="default" size="100%">Catamo, Eulalia</style></author><author><style face="normal" font="default" size="100%">Polesello, Vania</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Segat, Ludovica</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Interleukin-18 gene promoter polymorphisms and celiac disease in Italian patients.</style></title><secondary-title><style face="normal" font="default" size="100%">Mol Biol Rep</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Mol.

The major genetic risk factors known are specific human leukocyte antigen (HLA)-DQ haplotypes, but other genetic factors are supposed to be involved. Interleukin-18 (IL-18) is a pro-inflammatory cytokine that has an important role in the immune defense and it has the potential to influence inflammatory disorders. IL-18 is able to promote Th1 cell development and it is expressed in the mucosa of the small intestine in celiac patients. Given the IL-18 biological role, and since a few studies have previously suggested its involvement in CD, in order to investigate the role of IL18 gene in the susceptibility to CD we have performed a case-control study, analyzing two IL18 gene promoter polymorphisms, previously reported to impair the transcriptional activity of the gene, (-137G &gt; C and -607C &gt; A, rs187238 and rs1946518 respectively). A total of 556 CD Italian patients and 582 controls, further stratified for HLA class II (DQ) CD risk haplotypes were enrolled. The -607A &gt; C A allele and A/A genotype, as well as the combination of this allele with the -137G allele in the AG haplotype, were associated with an increased risk towards CD development, in particular in HLA-DQ2.2 patients. Although the association was very moderate, our results indicate the possible involvement of IL18 gene in the susceptibility to CD, and for this reason we do think it should deserve further investigation.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/25374428?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Zupin, Luisa</style></author><author><style face="normal" font="default" size="100%">Polesello, Vania</style></author><author><style face="normal" font="default" size="100%">Catamo, Eulalia</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Segat, Ludovica</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Interleukin-10 gene promoter polymorphisms in celiac patients from north-eastern Italy.</style></title><secondary-title><style face="normal" font="default" size="100%">Hum Immunol</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Hum.

In the present study, the -1082A&gt;G, -819T&gt;C and -592A&gt;C IL10 functional polymorphisms were analyzed in 565 celiac patients and 576 healthy controls from north-eastern Italy, stratified for HLA class II celiac disease risk haplotypes. No significant differences were observed for the three IL10 polymorphisms distribution between celiac patients and controls with the exception of a slightly increased risk for the -1082A allele in HLA-DQ8 male individuals. Although our findings suggest that the IL10 genetic variants analyzed do not have a major role in the susceptibility to the development of celiac disease in north-eastern Italian patients, we think that the possible involvement of IL10 gene in CD should deserve further investigation and that large-scale studies are recommended to confirm our findings.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/24768947?dopt=Abstract</style></custom1></record></records></xml>
