A new DNA receptor

免疫系统已经进化到对抗致病微生物。首先，它必须认识到一种传染性病原体已经入侵。为了做到这一点，我们已经开发了许多探针（受体），感觉微生物产品。检测微生物DNA是一个关键的警钟。然而，将病原体DNA与我们自己的DNA区分开来是困难的，因为两者看起来很相似。我们已经发现了一种新的受体，可以帮助我们识别细菌DNA，并提醒免疫系统即将发生的危险。

The immune system has evolved to fight disease-causing microbes. First, it has to recognize that an infectious agent has invaded. To do this we have developed many probes (receptors) that sense microbial products. Detecting microbial DNA is a critical alarm bell. However, distinguishing pathogen DNA from our own DNA is difficult because both look alike. We have identified a new receptor that helps us identify bacterial DNA and alerts the immune system to the imminent danger.
