| 1 | Analyzing the H19-and T65-epitopes in 38 kd phosphory-lated protein of Marek's disease viruses and comparing chicken immunological reactions to viruses point-mutated in the epitopes显示文摘DNA sequencing analysis in 38 kd phosphorylated protein (pp38) ORF of Marek's disease viruses (MDV) indicated that all tested 10 virulent strains with different pathotypes had 'A' at base #320 and glutamine at aa#107 while reacted with monoclonal antibody (Mab) H19 in indirect fluorescence antibody test (IFA). However, vaccine strain CVI988 had 'G' at base#320 and arginine at aa#107 instead, when it was negative in IFA with Mab H19. Some strains were also reactive with Mab T65 in IFA while there was 'G' at base #326 and glycine at aa#109, but the other strains, which had 'A' at base #326 and glutamic acid at aa#109, did not react with Mab T65. By comparison of CVI988 to its point mutants CVI/rpp38(AG) and CVI/rpp38(AA) with 1 or 2 base(s) changes at bases #320 and /or #326 of pp38 gene for their reactivity with Mab H19 and T65, it was confirmed that the glutamine at aa#107 and glycine at aa#109 were critical to epitopes H19 and T65 respectively. Immuno-reactions to MDV were compared in SPF chickens inoculated with cloned CVI988 and its mutant CVI/rpp38(AG). It was found that antibody responses to MDV in chickens inoculated with CVI/rpp38(AG) were delayed and significantly lower than that in chickens inoculated with the native CVI988. By differential comparison of antibody titers to different antigens, a third epitope specific to CVI988 and dependent on arginine at aa#107 was suggested to be responsible for the big difference in antibody responses induced by native CVI988 and its mutant. | Lee Lucy F | 2004 | Science China(Life Sciences)2004，47，1： | 2 |
| 2 | 马立克氏病病毒MEQ蛋白对MDV增殖影响的研究显示文摘在马立克氏病病毒 MDV致病机理的研究中 ,弄清致病基因 meq与病毒增殖之间的关系及其分子机制是十分重要的基础。以重组反转录病毒 (RCAS meq)感染鸡胚成纤维细胞 (CEF) ,使源于 MDV强毒参考株 (v MDV) GA株的 meq基因表达于宿主细胞内 ,然后再用 GA株感染这些细胞。通过利用 MDV强毒株特异的抗 pp3 8单克隆抗体所进行的“黑斑”试验以确定 MDV的增殖水平 ,并与未接种 RCAS meq的CEF进行比较。研究结果发现 ,细胞内表达的 meq基因产物可促进 GA株于体外培养细胞中的感染与增殖(病毒斑数增多 )。根据试验的结果 ,作者认为 meq基因在感染细胞内的表达水平是 MDV增殖以及进而能致病。 | 韦平 Lucy F Lee | 2002 | 广西农业生物科学2002，21，1： | 2 |
