DESCRIPTION (provided by applicant): The Southern California Primary Infection Program includes sites in San Diego and Los Angeles with a track record of identifying substantial cohorts with acute and early HIV infection. These cohorts have participated in longitudinal studies of natural history, pathogenesis, and therapeutic interventions with both antiretroviral drugs and vaccines. A series of excellent collaborations have resulted in completed studies characterizing HIV dynamics, apoptosis, CTL and CD4 proliferate responses, neutralizing antibody, and transmission of HIV drug resistance. These studies consist of both site and AIEDRP-wide studies coordinated in San Diego. Ongoing and proposed studies include the characterization of CD4 and CD8 responses to full length HIV reading frames, the relative contributions of immune responses to consensus and autologous sequences of HIV, the generation of neutralizing antibody (nAb) responses to autologous virus, the emergence of escape mutations over the full length sequence of HIV to each of these immune responses, the role of Nef in CTL control of HIV infection and escape from it, the population biology of HIV in genital secretions, and the dynamics of latent HIV infection in primary infection. We have also coordinated an additional AIEDRP-wide study of CTL responses in preparation for a therapeutic vaccine study. These studies will not only help to better characterize the natural history and pathogenesis of primary HIV infection, they will provide invaluable information to design strategies to prevent HIV transmission, to reduce secondary HIV drug resistance and to design and evaluate strategies for both prophylactic and therapeutic vaccines. A major component of this application is also the commitment to provide a state-of-the-art data management system and methods capable of supporting the projects of multiple local investigators as well as complimenting the resources of the central AIEDRP database. We will develop a set of on-line resources and communications technologies that facilitate scholarly exchange, distance-independent collaboration, information dissemination, education and training.

描述（由申请人提供）：南加州初级感染计划包括圣地亚哥和洛杉矶的站点，这些站点具有识别大量急性和早期 HIV 感染人群的记录。这些队列参与了自然史、发病机制以及抗逆转录病毒药物和疫苗的治疗干预的纵向研究。一系列出色的合作已经完成了表征 HIV 动力学、细胞凋亡、CTL 和 CD4 增殖反应、中和抗体以及 HIV 耐药性传播的研究。这些研究包括在圣地亚哥协调的现场研究和 AIEDRP 范围内的研究。正在进行的和拟议的研究包括 CD4 和 CD8 对全长 HIV 阅读框反应的表征、免疫反应对 HIV 共有序列和自体序列的相对贡献、对自体病毒的中和抗体 (nAb) 反应的产生、逃逸的出现HIV全长序列对这些免疫反应的突变、Nef在CTL控制HIV感染和逃避HIV中的作用、生殖器分泌物中HIV的群体生物学以及原发性HIV感染的动态 感染。我们还协调了一项额外的 AIEDRP 全范围 CTL 反应研究，为治疗性疫苗研究做准备。这些研究不仅有助于更好地描述原发性艾滋病毒感染的自然史和发病机制，还将为设计预防艾滋病毒传播的策略、减少继发性艾滋病毒耐药性以及设计和评估预防性和治疗性疫苗的策略提供宝贵的信息。 。该应用程序的一个主要组成部分还致力于提供最先进的数据管理系统和方法，能够支持多个当地研究人员的项目，并补充中央 AIEDRP 数据库的资源。 我们将开发一套在线资源和通信技术，以促进学术交流、远程合作、信息传播、教育和培训。
