最近的研究表明,冠状病毒(CoV)的复制依赖于活跃的亲免素途径。在这里,我们证明药物 FK506(他克莫司)在细胞培养物中以低、非细胞毒性浓度强烈抑制人类冠状病毒 SARS-CoV、HCoV-NL63 和 HCoV-229E 的生长。如噬菌斑滴定、qPCR、荧光素酶和绿色荧光蛋白 (GFP) 报告基因表达所示,复制减少了几个数量级。 CaCo2 细胞中细胞 FK506 结合蛋白 FKBP1A 和 FKBP1B 的敲低可阻止 HCoV-NL63 的复制,表明病毒生长需要亲免素家族的这些成员。
Recent research has shown that Coronavirus (CoV) replication depends on active immunophilin pathways. Here we demonstrate that the drug FK506 (Tacrolimus) inhibited strongly the growth of human coronaviruses SARS-CoV, HCoV-NL63 and HCoV-229E at low, non-cytotoxic concentrations in cell culture. As shown by plaque titration, qPCR, Luciferase- and green fluorescent protein (GFP) reporter gene expression, replication was diminished by several orders of magnitude. Knockdown of the cellular FK506-binding proteins FKBP1A and FKBP1B in CaCo2 cells prevented replication of HCoV-NL63, suggesting the requirement of these members of the immunophilin family for virus growth.
