The association between promoter polymorphism of the interleukin-10 gene and Alzheimer's disease

The importance of the role of inflammation has been suggested in the pathogenesis of Alzheimer's disease (AD). Interleukin-10 (IL-10) is an anti-inflammatory cytokine that may modulate the progression of the disease through the inhibition of the action of pro-inflammatory cytokines. In this study, three polymorphisms in the regulatory region of the IL-10 gene (-1082, -819 and -592) in 95 Chinese AD patients and 117 age-matched healthy Chinese subjects were investigated. We found that among the Chinese population, the A and C alleles at the -592 position are strongly linked to the T and C alleles at the -819 position, respectively. A strong association with AD was found for these two IL-10 polymorphisms, which are in complete linkage disequilibrium (-592C and -819C), and the odds ratio of AD is 4.03 (95% CI 1.23-13.23; p = 0.011). The functional significance of the IL-10 genotype was further supported by the significant association between plasma IL-10 concentrations and genotypes that were found in an independent sample of 160 healthy male volunteers. No interaction effect between the ApoE and IL-10 genotypes is found. Therefore, we concluded that the functional polymorphisms of the IL-10 gene act as a risk factor for AD.

目的 探讨中国天津地区汉族人群白细胞介素-10(interleukin-10,IL-10)-592C/A基因多态性的功能性以及其对经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)术后再狭窄的发病,PCI术后血清IL-10水平的影响.方法 对437例接受PCI并进行冠状动脉造影随访的患者,按冠状动脉造影结果分为再狭窄组(166例)和非再狭窄组(271例),应用聚合酶链反应-限制性片段长度多态性方法检测IL-10-592位点基因型和等位基因频率的分布;用酶联免疫吸附试验法测定2组PCI术前及PCI术后24 h血清IL-10浓度,并比较两组间和各基因型间IL-10水平.结果 (1)IL-10-592C/A基因型和等位基因频率在再狭窄组和非再狭窄组之间差异无统计学意义(P均＞0.05);(2)PCI术后24 h血清IL-10水平再狭窄组显著低于非再狭窄组[(82.67±35.02)ng/Lvs.(95.08±32.26)ng/L,P＜0.05];(3)IL-10-592位点A等位基因携带者(AA+AC基因型)术后24 h血清IL-10水平明显低于非携带者(CC型)[(86.13±34.77)ng/L vs.(102.50±27.52)ng/L,P＜0.05];(4)再狭窄组A等位基因携带者术后24 h血清IL-10水平明显低于非携带者[(78.51±34.09)ng/L vs.(102.19±33.66)ng/L,P＜0.05];(5)再狭窄危险的多因素Logistie回归分析显示:急性冠状动脉综合征、术前狭窄程度、靶病变长度与冠状动脉内支架再狭窄呈正相关(()R值分别为5.90、1.86、2.83),术后24 h血清IL-10水平、参照血管直径、支架直径与冠状动脉内支架再狭窄呈负相关(OR值分别为0.99、0.70、0.46).结论 (1)IL-10基因-592 C/A多态性与中国天津地区汉族人群再狭窄发病无关;(2)IL-10是PCI术后早期的炎症细胞因子,术后24 h血清IL-10水平为再狭窄的独立预测因素,携带A等位基因的个体可能通过降低其表型血清IL-10水平而增加了冠状动脉内支架术后再狭窄的发病.

Abstract：

Objective To investigate the relationship of interleukin-10 gene (IL-10)polymorphism and the serum IL-10 level with restenosis after percutaneous coronary intervention (PCI) in Tianjin Chinese Han population and study the effect of IL-10 gene polymorphism on serum IL-10 level. Methods Four hundred and thirty-seven patients who successfully underwent PCI with a follow-up angiography were divided into a restenosis group (n= 166) and non-restenosis group (n= 271). The IL-10 gene promoter polymorphism at position -592 was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Meanwhile their serum IL-10 level before and 24 h after PCI was determined by enzyme-linked immunosorbent assay (ELISA). Results (1) There was no significant difference in frequencies of -592 genotypes and alleles between the two groups (P＞0. 05); (2) The 24 hpost-PCI IL-10 serum level of restenosis group was significantly lower than that of the non-restenosis group [(82. 67±35. 02) ng/L vs. (95.08±32.26) ng/L, P＜0.05]; (3) The serum level of the A allele carriers (AA+AC) was significant lower than that of the CC carriers [(86.13±34.77) ng/L vs. (102. 50±27.52)ng/L,P＜0.05]; (4) In the restenosis group, the 24 h post-PCI serum level of IL-10 in the A allele carriers was also significantly lower than that in those without the A allele [(78.51 ± 34.09) ng/L vs. (102.19 ±33.66) ng/L, P＜ 0. 05]; (5) Logistic regression analysis revealed positive correlations between acute coronary syndrome patients, pre-PCI degree of stenosis, length of target stenosis lesion and restenosis (OR=5.90, 1.86, 2.83 respectively); and there were negative correlations between 24 h post-PCI serum level of IL-10, the stent diameter, the diameter of reference vessel before stent implantation and restenosis (OR=0. 99, 0. 70, 0. 46 respectively). Conclusion (1) TheIL-10 gene -592 C/A polymorphism was not associated with restenosis in the Tianjin Chinese Han population; (2) IL-10 is an early post-PCI inflammatory cytokine, 24 h post-PCI serum IL-10 level was an independent predictive factor for restenosis,the IL-10 A allele carriers may have increased incidence of in-stent restenosis (ISR) by reducing the serum IL-10 levels.

The interleukin-10-1082 promoter polymorphism and cancer risk: a meta-analysis

Interleukin-10 (IL-10) is a multifunctional cytokine with both immunosuppressive and anti-angiogenic properties and play an important role in the pathogenesis of cancer. IL-10-1082A>G polymorphism is the most extensively studied polymorphism in the IL-10 gene in cancer susceptibility. To date, a number of case-control studies were conducted to investigate the association between IL-10-1082A>G polymorphism and cancer risk in humans. However, the association between the IL-10-1082A>G polymorphism and cancer risk is still ambiguous. In an effort to solve this controversy, we performed a meta-analysis based on 61 case-control studies, including 14,499 cancer cases and 16,967 controls. We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association. In the stratified analyses by specific cancer type, increased risk was found in lung cancer (OR = 3.16, 95% CI = 1.16-8.63 for GA versus AA; OR = 2.07, 95% CI = 1.16-3.70 for GG versus AA; OR = 3.17, 95% CI = 1.31-7.68 for GA/GG versus AA) and non-Hodgkin's lymphoma (OR = 1.18, 95% CI = 1.02-1.36 for GA versus AA; OR = 1.17, 95% CI = 1.02-1.35 for GA/GG versus AA). The meta-analysis also indicated that the variant genotypes were associated with a moderately increased risk in Asians in all genetic models (OR = 1.80, 95% CI = 1.17-2.76 for GA versus AA; OR = 3.32, 95% CI = 1.62-6.82 for GG versus AA; OR = 1.67, 95% CI = 1.07-2.60 for GA/GG versus AA; OR= 2.93, 95% CI = 1.43-6.03 for GG versus AA/GA). The meta-analysis suggested that the IL-10-1082A>G polymorphism was associated with increased risk of cancer in Asians and lung cancer and non-Hodgkin's lymphoma. To draw comprehensive and true conclusions, more researches with larger numbers of worldwide participants are needed to examine associations between IL-10-1082A>G polymorphism and cancer risk.     

The interleukin-10 gene promoter polymorphism -1087AG does not correlate with clinical outcome in non-Hodgkin's lymphoma

The Interleukin 10 (IL-10) gene is highly polymorphic, and the IL-10(-1087AG) (rs1800896) gene variation is the only so far studied intensively in association with certain diseases. Conflicting data have been published about an association of IL-10(-1087AG) gene variation with lower rates of complete remission and lower overall survival (OS) in patients with diffuse large B-cell lymphoma. To further investigate this in malignant lymphoma, we established the IL-10 genotypes in patients from the NHL-B1/ B2 studies from the German High-Grade Non-Hodgkin's Lymphoma Study Group. In our study, allele frequencies of lymphoma patients are comparable as in healthy controls. No increase of IL-10(-1087G) alleles was found. In addition we did not find any difference in OS or event-free survival between patients with IL-10(-1087AA) and the other genotypes. Comparable results were obtained for the IL-10 loci at -3538 (A/T), -1354 (A/G), -824 (C/T) and -597 (A/C) (rs1800890, rs1800893, rs1800871 and rs1800872).     

IL-10 gene polymorphism and herpesvirus infections

Genetics has an important role in resistance to various infections and it also may modify the clinical picture of an infectious disease. Here, we briefly review our recent data demonstrating that the polymorphism of the IL-10 gene is associated with resistance to some common herpesviruses and, additionally, that this same gene is involved in the regulation of the severity of the infection and in the reactivation process.
