  • 肾综合征出血热(hemorrhagic fever with renal syndrome,HFRS)由汉坦病毒感染引起,我国是高发地区。β3整合素为致病性汉坦病毒在易感细胞上的主要受体,由β3亚基参与组成的整合素有αVβ3和αIIbβ3两种。既往研究表明整合素αIIbβ3的单核苷酸多态性(SNP)与汉坦病毒感染有一定关联性,而整合素αVβ3 SNP与汉坦病毒感染的关联性未见报道。本实验采用TaqMan SNP基因分型探针实时定量PCR和双向等位基因特异性PCR(BI-PASA)两种方法对整合素αVβ3 SNP rs5918、rs3768777、rs3738919、rs13306487、rs5921进行基因分型,研究整合素αVβ3 SNP 与HV感染的关联性。结果发现湖北地区汉族人群中HFRS患者整合素αVβ3五个位点的单核苷酸基因多态性与汉坦病毒感染易感性及疾病严重程度无关联性。

  • Hantaviruses belong to the family Bunyaviridae and cause hemorrhagic fever with renal syndrome (HFRS) in humans. β3 integrins, including αVβ3 and αIIbβ3 integrins, act as receptors on endothelial cells and play key roles in cellular entry during the pathogenesis of hantaviruses. Previous study demonstrated that the polymorphisms of integrin αIIbβ3 are associated with susceptibility to hantavirus infection and the disease severity of HFRS in Shaanxi Province of China, rather than in Finland. However, the polymorphisms of integrin αvβ3 in patients with HFRS was incompletely understood. Here, we aimed to investigate the associations between polymorphisms in human integrin αvβ3 and HFRS in Han Chinese individuals. Ninety patients with HFRS and 101 healthy controls were enrolled in this study. Analysis of five single nucleotide polymorphism (SNP) sites (rs3768777 and rs3738919 on ITGAV; rs13306487, rs5921, and rs5918 on ITGB3) was performed by TaqMan SNP genotyping assays and bi-directional PCR allele-specific amplification method. No significant differences were observed between the HFRS group and controls regarding the genotype and allele frequency distributions of any of the five SNP sites, and no associations were found between ITGAV polymorphisms/genotypes and disease severity. In conclusion, our results implied that these five SNPs in the integrin αvβ3 gene were not associated with HFRS susceptibility or severity in Han Chinese individuals in Hubei Province.

    Abstract: Hantaviruses belong to the family Bunyaviridae and cause hemorrhagic fever with renal syndrome (HFRS) in humans. β3 integrins, including αVβ3 and αIIbβ3 integrins, act as receptors on endothelial cells and play key roles in cellular entry during the pathogenesis of hantaviruses. Previous study demonstrated that the polymorphisms of integrin αIIbβ3 are associated with susceptibility to hantavirus infection and the disease severity of HFRS in Shaanxi Province of China, rather than in Finland. However, the polymorphisms of integrin αvβ3 in patients with HFRS was incompletely understood. Here, we aimed to investigate the associations between polymorphisms in human integrin αvβ3 and HFRS in Han Chinese individuals. Ninety patients with HFRS and 101 healthy controls were enrolled in this study. Analysis of five single nucleotide polymorphism (SNP) sites (rs3768777 and rs3738919 on ITGAV; rs13306487, rs5921, and rs5918 on ITGB3) was performed by TaqMan SNP genotyping assays and bi-directional PCR allele-specific amplification method. No significant differences were observed between the HFRS group and controls regarding the genotype and allele frequency distributions of any of the five SNP sites, and no associations were found between ITGAV polymorphisms/genotypes and disease severity. In conclusion, our results implied that these five SNPs in the integrin αvβ3 gene were not associated with HFRS susceptibility or severity in Han Chinese individuals in Hubei Province.
