Project Summary A comprehensive interdisciplinary approach proposed to support the Single Cell Opioid Responses in the Context of HIV (SCORCH) Program Expansion: CNS Data Generation for Chronic Opioid, Methamphetamine, and/or Cocaine Exposures RFA from the National Institute on Drug Abuse (NIDA). We will perform studies on the interplay of HIV pathogenesis and opioid abuse in the gold-standard SIV/nonhuman primate system, using single-cell RNA sequencing (scRNAseq) to assess individual cellular transcriptomes. This will give us obtain unparalleled insight into the viral and drug-induced effects on diverse cell types in brain in regions critical for HIV infection and opioid abuse. In addition, we will also focus on primary targets of HIV and drivers of neuropathogenesis, microglia and brain macrophages, using scRNAseq as well as single-cell Assay for Transposase-Accessible Chromatin sequencing (scATACseq) to gain insight into the epigenetic regulation of gene expression at the single cell level. These will be combined with state-of-the-art sensitive assays for virus in the brain. We will ensure our data adhere to the FAIR (Findable, Accessible, Interoperable, and Reusable) standards, and will work closely with other members of the SCORCH program to share and disseminate data to yield maximal advancement to the field. Our experiments are carefully designed to address the role of virus, drugs, and their interactions, as well as include the clinically relevant scenarios of those taking antiretrovirals to suppress virus, and those who do not. Our rigor and reproducibility are facilitated by our detailed power analysis with proper sample sizes, as well as our experimental design to match the standards of blocking, replication and randomization. The results from these studies will provide novel insights into the CNS effects of HIV and drug abuse.

项目摘要 提出了一种全面的跨学科方法，以支持单细胞阿片类药物反应 艾滋病毒（Scorch）计划扩展的上下文：慢性阿片类药物的CNS数据生成，甲基苯丙胺， 和/或可卡因暴露于美国国家药物滥用研究所（NIDA）。我们将进行研究 使用金标准SIV/非人类灵长类动物系统中HIV发病机理和阿片类药物滥用的相互作用，使用 单细胞RNA测序（SCRNASEQ），以评估单个细胞转录组。这将使我们获得 对病毒和药物诱导的对艾滋病毒至关重要的大脑各种细胞类型的影响的无与伦比的洞察力 感染和阿片类药物滥用。此外，我们还将重点关注艾滋病毒的主要目标和驱动因素 神经病生成，小胶质细胞和脑巨噬细胞，使用SCRNASEQ以及单细胞测定法 转座酶可访问的染色质测序（SCATACSEQ），以深入了解表观遗传调节 基因表达在单细胞水平上。这些将与对病毒的最新敏感测定法相结合 在大脑中。我们将确保我们的数据遵守博览会（可找到，可访问，可互操作和可重复使用） 标准，并将与Scorch计划的其他成员紧密合作，以共享和传播数据 在该领域产生最大进步。我们的实验经过精心设计，以解决病毒的作用， 药物及其相互作用，包括服用抗逆转录病毒病的人的临床相关情况 抑制病毒，以及那些没有的人。我们的详细功率分析促进了我们的严格和可重复性 具有适当的样本量以及我们的实验设计，以符合阻塞，复制和 随机化。这些研究的结果将提供对HIV和药物中枢神经系统影响的新见解 虐待。
