This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. To work on developing a vaccine for HIV, we will identify additional epitopes for cytotoxic and helper T cells and use this information to develop unique reagents for following immune responses. The binding motif for Mamu-B*01 was defined, potential SIV peptides screened and 35 new Mamu-B*01 epitopes are being screened. Despite its high frequency, we have been unable to find any B*01 epitopes for SIV and have found that one epitope previously published is erroneous. We have continued to develop additional tetramers and now have 21 Mamu-A*01, 15 Mamu-A*02, 6 Mamu-B*17 tetramers in regular production, as well as many more under development. This research used WNPRC Immunogenetics & Virology Services and Animal Services.

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。为了开发HIV疫苗，我们将识别更多的细胞毒性和辅助T细胞表位，并利用这些信息开发用于后续免疫反应的独特试剂。确定了MAMU-B*01的结合基序，筛选了潜在的SIV多肽，并正在筛选35个新的MAMU-B*01表位。尽管它的频率很高，但我们一直无法找到任何SIV的B*01表位，并发现先前发表的一个表位是错误的。我们一直在继续开发更多的四聚体，目前已有21个MAMU-A*01、15个MAMU-A*02、6个MAMU-B*17四聚体在正常生产中，以及更多的正在开发中。这项研究使用了WNPRC免疫遗传学和病毒学服务以及动物服务。
