We reported that IFN-λ is the predominant IFN induced from RSV infected nasal epithelial cells. However, there were no-significant difference between IFN-λand IFN-βin nasal discharge of RSV-infected child. Streptococcus pneumonia and chemokines in nasal discharge were detected. Humuleone, the main constituent of hop bitter acids, inhibited RSV replication and chemokines production, and Clarithromycis, antimicrobial agent, inhibited chemokines production and PAF expressioni, which is the receptor of S. pneumonia. These results suggested new treatment approach to RSV infection.

我们报告说，IFN-λ是由RSV感染的鼻皮细胞诱导的主要IFN。但是，IFN-λ和IFN-βIN鼻腔分泌物的RSV感染儿童之间没有显着差异。检测到肺炎链球菌和趋化因子在鼻腔排出中。 Humuleone是Hop苦酸的主要构成，抑制了RSV复制和趋化因子的产生，而抗菌剂Clarithromycis抑制了趋肺链球菌的趋化因子的产生和PAFESPARCEI。这些结果提出了RSV感染的新治疗方法。
