目的分析不同亚型丙型肝炎病毒(HCV)包膜糖蛋白E1和E2的变异性。方法从HCV基因数据库中获得不同亚型HCV包膜序列,并利用生物信息学方法进行核苷酸序列变异性、包膜糖蛋白亲水性性及糖基化位点分析。结果与其他亚型相比,1b亚型HCV包膜糖蛋白E1和E2区核苷酸的变异性最高,且E1区的变异性高于E2区;在E1区55,72位和102—112位氨基酸处1b亚型亲水性较大;1b亚型的包膜糖蛋白E1区N一糖基化位点数最多,且在60位氨基酸处单独有一糖基化位点。结论与E2区相比,E1区的高突变可能与1b型HCV致病性较强关系密切,且1b亚型E1蛋白的大量糖基化也可能存病毒的致病及角癌挑浼中有一审作用。 相似文献

Objective To investigate the utility of the HCV core antigen ELISA in the detection of HCV infection in hemodialysis patients and to compare with Anti-HCV antibodies 3rd generation ELISA.Methods Two hundred fifty hemodialysis patients were included in the study. Anti-HCV antibodies and total HCVcAg was determined by ELISA kits. HCV RNA was determined using reverse transeriptase polymerase chain reaction (RT-PCR) .Results Forty-three out of 250 (17.2%) patients were positive for anti-HCV antibodies and 18% WERE positive for HCVcAg. 13/250 (5.2%) were positive for HCVcAg but anti-HCV negative, All 13 were confirmed viremic by in-house nested RT-PCR leading to specificity of 100%. Viral load of (49258±28682) copies/ml were detected in HCVcAg positive cases was higher in comparison to (23938±10780) copies/ml in the anti-HCV positive group (P < 0.05). The viral load of 4 negative cases for HCVcAg assay but anti-HCV positive was 306±161 copies/rnl which was significantly lower in comparison to HCVcAg positive group (P < 0.001). Conclusion Detection of total HCVcAg together with anti-HCV will be useful for patients undergoing hemodialysis who have a longer window period due to immunosuppressed state. HCVcAg was compatible for the HCV RNA in serum and total HCVcAg ELISA is beth a cost-effective and a less labor-intensive alternative to PCR, enhancing its clinical utility. 相似文献
