高效抗逆转录病毒治疗法(HAART)的推广使用有效地抑制了HIV-1病毒的传播和艾滋病(AIDS)的发病率、死亡率。近年来,HIV-1逆转录酶基因突变所导致的耐药性成为了HAART的治疗失败的主要原因,耐药性突变的检测对于指导病人用药以及新药开发具有重要意义。本工作发展了一种检测HIV-1逆转录酶基因耐药性突变的新方法。采用两步MS-PCR方法检测HIV-1 B亚型野生型和耐药突变型逆转录酶基因突变,检测点包括M41L、K70R、K103N、Y181C和T215,并在两步MS-PCR基础上,设计比野生型引物长的突变型引物,结合微孔板杂交ELISA呈色技术检测各点突变。结果显示,简化的两步MS-PCR能保持灵敏度和特异性高的优点,ELISA的阳性结果与阴性结果的比值(P/N)达到要求,两步MS-PCR结合ELISA方法灵敏度高,操作简单、结果直观、成本低、相对耗时短且能进行高通量检测,其无论在HIV-1耐药性突变及其它的点突变检测中具有较好的临床应用前景。 相似文献

Background
The functional relevance of many of the recently detected JAK2 mutations, except V617F and exon 12 mutants, in patients with chronic myeloproliferative neoplasia (MPN) has been significantly overlooked. To explore atomic-level explanations of the possible mutational effects from those overlooked mutants, we performed a set of molecular dynamics simulations on clinically observed mutants, including newly discovered mutations (K539L, R564L, L579F, H587N, S591L, H606Q, V617I, V617F, C618R, L624P, whole exon 14-deletion) and control mutants (V617C, V617Y, K603Q/N667K). 相似文献19.
