项目摘要

PROJECT SUMMARY The human microbiome is a key regulator of host immune function, and growing consensus suggests this relationship is likely mediated by host interactions with microbial derived small molecules (i.e., metabolites). Accordingly, microbial derived metabolites have been associated with numerous autoimmune, allergic, and infectious diseases. However, the host-microbiome circuits that form the molecular basis of these associations have not been fully characterized, and many microbial derived metabolites have not even been formally identified. In this proposal, we describe a strategy to identify and functionally characterize microbial derived metabolites isolated from patients in health and autoimmunity. Our collaborative team will isolate and characterize novel metabolites from the human microbiome, map these associations to human immune pathways, and identify the specific host receptors that engage microbial derived metabolites. This proposal will establish causal relationships between microbial metabolites and human immune system function.

项目摘要人类微生物组是宿主免疫功能的关键调节剂，而增长的共识表明这一点关系可能是由宿主与微生物衍生的小分子（即代谢产物）相互作用介导的。因此，微生物衍生的代谢产物与大量自身免疫，过敏和传染病。但是，构成这些关联的分子基础的宿主微生物电路尚未完全表征，许多微生物衍生的代谢物甚至没有正式确定。在此提案中，我们描述了一种识别和功能表征微生物的策略从健康和自身免疫的患者中分离出来的代谢产物。我们的协作团队将隔离和表征来自人类微生物组的新型代谢产物，将这些关联映射到人免疫途径，并确定参与微生物衍生代谢产物的特定宿主受体。该提议将建立微生物代谢产物与人免疫系统功能之间的因果关系。
