项目摘要

PROJECT SUMMARY This study investigates how the body maintains a memory of ‘Self’. When facing foreign organisms and cancer, this self-knowledge is thought to be critical, serving to educate the immune system to limit autoimmunity and conversely license reactivity to things that are ‘Foreign’. The core of the study focuses on a newly-discovered organelle, found within macrophages and some dendritic cells which we call the Self-Associated Storage Organelle or SASO for short. We believe that the SASO is critical to ‘hold’ our self-identity and subsequently educate the rest of our immune system and it appears to come from a stealthy and subtle form of ‘cell nibbling’.Our proposal is unique in applying cutting technologies—lattice-light sheet imaging, vesicle flow, Mass- spectrometry and Electron Microscopy—together with conventional cellular immunoassay methods and genetic screens, to understand how this newly described component of the immune system works as well as how we can harness it to improve health. The resultant discoveries will be formative for designing new ways to boost anti-tumor immunity, to minimize autoimmunity and to broadly regulate which components of our bodies are seen as ‘Self’.

项目摘要这项研究调查了身体如何保持“自我”的记忆。在面对外国生物和癌症时，人们认为这种自我知识至关重要，有助于教育免疫系统以限制自身免疫性和相反，许可对“外国”事物的反应性。研究的核心重点是新发现细胞器，在巨噬细胞和一些树突状细胞中发现，我们称之为自我相关的存储细节或SASO简称。我们认为，SASO对于“保持”我们的自我身份至关重要教育我们的其余免疫系统，它似乎来自一种隐秘和微妙的'细胞 nibbling'.our提案在应用切割技术方面是独一无二的 - 片段光片成像，囊泡流，质量 - 光谱和电子显微镜 - 与常规的细胞免疫测定法和遗传学屏幕，了解免疫系统的新描述的组成部分以及我们如何运作可以利用它来改善健康。最终发现将是设计新方法来提高的形成抗肿瘤免疫学，以最大程度地减少自身免疫性并广泛调节我们身体的哪些成分作为“自我”。
