由于缺乏适当的实验模型,对阴道人类免疫缺陷病毒1型(HIV-1)进入和感染的初始事件的理解受到阻碍。在这里,我们表明,在离体人体器官培养系统,在原位接触后,HIV-1迅速渗透上皮内阴道朗格汉斯和CD 4 + T细胞。HIV-1几乎完全通过CD 4和CCR 5受体介导的直接融合进入CD 4 + T细胞,而不需要从朗格汉斯细胞传代,随后发生明显的生产性感染。相比之下,HIV-1主要通过内吞作用,通过多种受体进入CD 1a+朗格汉斯细胞,病毒体在细胞质内完整持续数天。我们的研究结果揭示了粘膜HIV感染在体内的最早阶段,并可能指导设计有效的策略来阻断局部传播和预防HIV-1传播。
Understanding the initial events in the establishment of vaginal human immunodeficiency virus type-1 (HIV-1) entry and infection has been hampered by the lack of appropriate experimental models. Here, we show in an ex vivo human organ culture system that upon contact in situ, HIV-1 rapidly penetrated both intraepithelial vaginal Langerhans and CD4+ T cells. HIV-1 entered CD4+ T cells almost exclusively by CD4 and CCR5 receptor-mediated direct fusion, without requiring passage from Langerhans cells, and overt productive infection ensued. By contrast, HIV-1 entered CD1a+ Langerhans cells primarily by endocytosis, by means of multiple receptors, and virions persisted intact within the cytoplasm for several days. Our findings shed light on the very earliest steps of mucosal HIV infection in vivo and may guide the design of effective strategies to block local transmission and prevent HIV-1 spread.
