项目摘要

ABSTRACT/PROJECT SUMMARY This proposal employs novel methods to identify key determinants and consequences of concurrent HIV infection and regular cannabis use. We will acquire extensive phenotype data from peripheral and brain markers of immune activation, brain structure, and neuropsychological performance (NP) in persons living with HIV (PLWH) receiving combination anti-retroviral therapy (cART) (80 regular cannabis users and 80 non-users) and HIV uninfected (HIV-) controls (80 regular cannabis users and 80 non-users). Our overall hypothesis is that cannabis use leads to increases in inflammation in the peripheral and brain compartments. We also hypothesize that phenotypic signatures due to regular cannabis use and HIV will be delineated through NP and brain volumetrics. In Aim 1 we hypothesize that regular cannabis use will increase both peripheral and brain immune indices in PLWH on cART. In Aim 2 we hypothesize that regular cannabis use will lead to a worsening of NP and reductions in brain volumetrics in both PLWH on cART and HIV- controls. This proposal will provide key insights into the effects of regular cannabis and HIV on peripheral and brain markers of immune function and NP in PLWH and HIV- controls. These insights are critical for cure strategies and ongoing HIV treatment initiatives.

摘要/项目摘要该提案采用新颖的方法来确定并发艾滋病毒的关键决定因素和后果感染和经常使用大麻。我们将从外周血和大脑中获取广泛的表型数据人类免疫激活、大脑结构和神经心理表现 (NP) 的标志物接受联合抗逆转录病毒治疗 (cART) 的艾滋病毒感染者 (PLWH)（80 名经常吸食大麻的人和 80 名非吸食者）和艾滋病毒未感染者（HIV-）控制（80 名经常吸食大麻的人和 80 名非吸食者）。我们的整体假设是大麻的使用会导致外周和脑室炎症增加。我们还假设，由于经常使用大麻和艾滋病毒而产生的表型特征将通过以下方式描述： NP 和脑容量。在目标 1 中，我们假设经常使用大麻会增加外周和 cART 感染者的脑免疫指数。在目标 2 中，我们假设经常使用大麻会导致接受 cART 的 PLWH 和 HIV 对照患者的 NP 恶化，脑容量减少。这个提议将提供有关常规大麻和艾滋病毒对外周和大脑标记物影响的重要见解 PLWH 和 HIV 对照者的免疫功能和 NP。这些见解对于治疗策略和正在进行的艾滋病毒治疗举措。
