RNA interference (RNAi) is a powerful host defense mechanism against viruses. As a counter-defense, many viruses encode suppressors of RNAi, which – in plants – has provoked counter-counter-defense strategies. Recently, a mechanism was proposed in Drosophila (Zhang et al.) wherein a long noncoding RNA senses a virus-encoded RNAi suppressor to activate an innate immune response.

对抗抗病毒RNAi的防御。

RNA干扰（RNAi）是针对病毒的强大宿主防御机制。作为防御，许多病毒都编码RNAi的抑制因子，而RNAi的抑制因子在植物中引发了反防御策略。最近，在果蝇中提出了一种机制（Zhang等人），其中长的非编码RNA感觉到病毒编码的RNAi抑制剂以激活先天免疫应答。
