人类免疫缺陷病毒-1 (HIV)感染是抗逆转录病毒治疗(ART)下的一种慢性疾病,在此期间,活跃的HIV复制被有效抑制。稳定的病毒库是在感染早期建立的,在艾滋病毒感染者(PWH)中仅通过抗逆转录病毒治疗无法根除,这具有残留的免疫炎症和疾病相关的继发性合并症。哺乳动物细胞具有综合应激反应(integrated stress response, ISR)机制,可检测内源性和外源性应激,如血红素缺乏、营养波动、未折叠蛋白积累和病毒感染。ISR是先天免疫的一部分,它防御病原体感染或环境改变,从而维持体内平衡以避免疾病。在这里,我们描述了这种机制如何响应ART的脱靶效应和外周细胞室和大脑中的持续HIV感染。后者可能对我们更好地理解稳定的HIV储存库和HIV相关神经认知障碍的机制很重要。病毒学;细胞生物学
Human immunodeficiency virus-1 (HIV) infection is a chronic disease under antiretroviral therapy (ART), during which active HIV replication is effectively suppressed. Stable viral reservoirs are established early in infection and cannot be eradicated in people with HIV (PWH) by ART alone, which features residual immune inflammation with disease-associated secondary comorbidities. Mammalian cells are equipped with integrated stress response (ISR) machinery to detect intrinsic and extrinsic stresses such as heme deficiency, nutrient fluctuation, the accumulation of unfolded proteins, and viral infection. ISR is the part of the innate immunity that defends against pathogen infection or environmental alteration, thereby maintaining homeostasis to avoid diseases. Here, we describe how this machinery responds to the off-target effects of ART and persistent HIV infection in both the peripheral compartments and the brain. The latter may be important for us to better understand the mechanisms of stable HIV reservoirs and HIV-associated neurocognitive disorders. Virology; Cell biology
