Combination antiretroviral therapy (cART) dramatically changed the face of the HIV/AIDS pandemic, making it one of the most prominent medical breakthroughs of the past 3 decades. However, as the life span of persons living with HIV (PLWH) continues to approach that of the general population, the same cannot be said regarding their quality of life. PLWH are affected by comorbid conditions such as high blood pressure, diabetes, and neurocognitive impairment at a higher rate and increased severity than their age-matched counterparts. PLWH also have higher levels of inflammation, the drivers of which are not entirely clear. As cART treatment is lifelong, we assessed here the effects of cART, independent of HIV, on primary human monocyte-derived macrophages (MDMs). MDMs were unskewed or skewed to an alternative phenotype and treated with Atripla or Triumeq, two first-line cART treatments. We report that Triumeq skewed alternative MDMs toward an inflammatory nonsenescent phenotype. Both Atripla and Triumeq caused mitochondrial dysfunction, specifically efavirenz and abacavir. Additionally, transcriptome sequencing (RNA-seq) demonstrated that both Atripla and Triumeq caused differential regulation of genes involved in immune regulation and cell cycle and DNA repair. Collectively, our data demonstrate that cART, independent of HIV, alters the MDM phenotype. This suggests that cART may contribute to cell dysregulation in PLWH that subsequently results in increased susceptibility to comorbidities.
联合抗逆转录病毒疗法(cART)极大地改变了 HIV/AIDS 大流行的面貌,使其成为过去 30 年来最显著的医学突破之一。然而,随着 HIV 感染者(PLWH)的预期寿命继续接近普通人群,他们的生活质量却并非如此。PLWH 患高血压、糖尿病和神经认知障碍等合并症的比例和严重程度高于年龄匹配的人群。PLWH 还具有更高水平的炎症,其驱动因素尚不完全清楚。由于 cART 治疗是终身的,因此我们在这里评估了 cART 对原发性人单核细胞衍生巨噬细胞(MDM)的影响,而不考虑 HIV。MDM 被未偏斜或偏斜为替代表型,并接受 Atripla 或 Triumeq 两种一线 cART 治疗。我们报告称,Triumeq 将替代 MDM 偏斜为炎症性非衰老表型。阿巴卡韦和依非韦伦会导致 Atripla 和 Triumeq 引起线粒体功能障碍。此外,转录组测序(RNA-seq)表明,阿巴卡韦和依非韦伦都导致参与免疫调节、细胞周期和 DNA 修复的基因的差异调节。总之,我们的数据表明,cART 可改变 MDM 表型,而与 HIV 无关。这表明 cART 可能导致 PLWH 中的细胞失调,进而导致合并症的易感性增加。
