Abstract

We identified primary human monocyte-derived macrophages (MDM) as vulnerable target cells for Zika virus (ZIKV) infection. We demonstrate dramatic effects of hemin, the natural inducer of the heme catabolic enzyme heme oxygenase-1 (HO-1), in the reduction of ZIKV replication in vitro. Both LLC-MK2 monkey kidney cells and primary MDM exhibited hemin-induced HO-1 expression with major reductions of >90% in ZIKV replication, with little toxicity to infected cells. Silencing expression of HO-1 or its upstream regulatory gene, nuclear factor erythroid-related factor 2 (Nrf2), attenuated hemin-induced suppression of ZIKV infection, suggesting an important role for induction of these intracellular mediators in retarding ZIKV replication. The inverse correlation between hemin-induced HO-1 levels and ZIKV replication provides a potentially useful therapeutic modality based on stimulation of an innate cellular response against Zika virus infection.

摘要

我们确定原代人单核细胞衍生的巨噬细胞(MDM)是寨卡病毒(ZIKV)感染的易感靶细胞。我们证明血红素(血红素分解代谢酶血红素加氧酶-1(HO-1)的天然诱导剂)在体外减少ZIKV复制方面具有显著作用。LLC-MK2猴肾细胞和原代MDM均表现出血红素诱导的HO-1表达,ZIKV复制大幅减少>90%,且对感染细胞几乎没有毒性。沉默HO-1或其上游调节基因核因子红细胞相关因子2(Nrf2)的表达,减弱了血红素诱导的对ZIKV感染的抑制作用,表明诱导这些细胞内介质在延缓ZIKV复制中起重要作用。血红素诱导的HO-1水平与ZIKV复制之间的负相关关系,基于刺激针对寨卡病毒感染的先天性细胞反应,提供了一种潜在有用的治疗方式。
