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. The best strategy for prevention of human immunodeficiency virus (HIV) infection involves the development of an effective vaccine. Herpes simplex virus (HSV) amplicons represent a novel and promising strategy for vaccine development. The studies described in this proposal will determine if HSV amplicons can elicit a significant immune response in the rhesus macaque. Specifically, rhesus macaques will be inoculated via an intramuscular route with HSV amplicons that express a replication-defective SIvmax239 genome or by control amplicons that do not express any SIV gene products. The cellular immune response to SIV proteins will be followed through analysis of CD4+ and CD8+ T cell responses, tetramer staining, and antigen-specific cytokine production. The humoral response will be determined by analysis of both serum and mucosal immunity. Finally, the innate immune response will be determined through analysis of both natural killer cells and by performing longitudinal studies of changes in lymphocyte proliferation and activation.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 预防人类免疫缺陷病毒（HIV）感染的最佳策略是开发有效的疫苗。 单纯疱疹病毒 (HSV) 扩增子代表了一种新颖且有前途的疫苗开发策略。 该提案中描述的研究将确定 HSV 扩增子是否可以在恒河猴中引发显着的免疫反应。 具体来说，恒河猴将通过肌内途径接种表达复制缺陷型SIvmax239基因组的HSV扩增子或不表达任何SIV基因产物的对照扩增子。 通过分析 CD4+ 和 CD8+ T 细胞反应、四聚体染色和抗原特异性细胞因子的产生来跟踪对 SIV 蛋白的细胞免疫反应。 体液反应将通过分析血清和粘膜免疫来确定。 最后，将通过分析自然杀伤细胞以及对淋巴细胞增殖和激活的变化进行纵向研究来确定先天免疫反应。
