结核分枝杆菌和人类免疫缺陷病毒-1(HIV-1)的综合征相互作用是一个主要的全球健康问题。尽管合并感染具有临床意义,但我们对合并感染的细胞病理生理学和治疗药效学影响的了解有限。在这里,我们使用单轮感染性HIV-1假型病毒颗粒,与M一起表达绿色荧光蛋白。表达mCherry的结核病研究发病机制和治疗。我们报道HIV-1感染抑制M.结核病,并证明抗病毒治疗(依法韦仑)和抗微生物治疗(利福平)的治疗活性。所描述的方法可以应用于详细的机制研究,以告知新的治疗策略的发展。
Mycobacterium tuberculosis and human immunodeficiency virus-1 (HIV-1) syndemic interactions are a major global health concern. Despite the clinical significance of coinfection, our understanding of the cellular pathophysiology and the therapeutic pharmacodynamic impact of coinfection is limited. Here, we use single-round infectious HIV-1 pseudotyped viral particles expressing green fluorescent protein alongside M. tuberculosis expressing mCherry to study pathogenesis and treatment. We report that HIV-1 infection inhibited intracellular replication of M. tuberculosis and demonstrate the therapeutic activity of antiviral treatment (efavirenz) and antimicrobial treatment (rifampicin). The described method could be applied for detailed mechanistic studies to inform the development of novel treatment strategies.
