现在公认的是,天然免疫系统通过模式识别受体识别损伤(或危险)和病原体相关的分子模式(分别为DAMP和PAMP),如Toll样受体(TLR)和/或Nod样受体(NLR)。不太清楚的是,对PAMP和DAMP的反应是否以及如何受到不同的调控。答案可能会揭示免疫系统的主要目标是防御感染还是提醒宿主组织损伤。我们最近证实宿主对DAMP的反应是由DAMP-CD24-Siglec轴控制的。在这里,我们提出了CD24-Siglec通路在区分DAMPS和PAMP中的关键作用。
It is now well accepted that the innate immune system recognizes both damage (or danger)- and pathogen-associated molecular patterns (DAMP and PAMP, respectively) through pattern recognition receptors, such as Toll-like receptors (TLR) and/or Nod-like receptors (NLR). Less clear are whether and how the response to PAMP and DAMP are differentially regulated. The answers may reveal whether the primary goal of the immune system is to defend against infections or to alert the host of tissue injuries. We demonstrated recently that the host response to DAMP is controlled by a DAMP-CD24-Siglec axis. Here we propose a key role for the CD24-Siglec pathway in discriminating between DAMPs and PAMPs.
