项目摘要

PROJECT ABSTRACT Inflammation in the central nervous system (CNS) is causally associated with the pathogenesis and progression of multiple demyelinating and neurodegenerative diseases, including Multiple Sclerosis (MS), Parkinson's Disease, Alzheimer's Disease, Amyotrophic Lateral Sclerosis, and general age-associated cognitive decline Therefore, there is an urgent need to develop novel approaches to prevent, limit or reverse neuroinflammation. Basic, translation and clinical studies indicate that T cells can be major drivers of inflammation in the CNS, but the mechanisms promoting or inhibiting these responses remain poorly defined. The fundamental focus of this research proposal is to: (i) interrogate a novel pathway by which the innate immune system controls T cell responses in the CNS, (ii) understand the regulation of these cellular interactions, and (iii) define whether it is possible to harness this or related pathways for therapeutic benefit in neuroinflammation. We will employ innovative approaches and develop new tools to address these fundamental gaps in knowledge, and where possible, translate our findings from mice into clinically defined patient samples. Results from these studies will advance our understanding of the pathways that promote or inhibit pro-inflammatory T cell responses in the CNS, and could provoke the next generation of novel preventative, therapeutic or curative treatment strategies for demyelinating and neurodegenerative diseases.

项目摘要中枢神经系统（CNS）的炎症与发病机制有因果关系，多种脱髓鞘和神经退行性疾病的进展，包括多发性硬化症 (MS)、帕金森病、阿尔茨海默病、肌萎缩侧索硬化症和一般与年龄相关的疾病因此，迫切需要开发新的方法来预防、限制或逆转认知能力下降神经炎症。基础、转化和临床研究表明，T 细胞可能是中枢神经系统炎症，但促进或抑制这些反应的机制仍不清楚。本研究提案的基本重点是：（i）探究一种新的途径，通过该途径先天免疫系统控制中枢神经系统中的 T 细胞反应，(ii) 了解这些反应的调节细胞相互作用，以及（iii）定义是否可以利用该途径或相关途径对神经炎症有治疗作用。我们将采用创新方法并开发新工具解决这些基本的知识差距，并在可能的情况下，将我们从小鼠身上得到的发现转化为临床定义的患者样本。这些研究的结果将加深我们对促进或抑制中枢神经系统中促炎性 T 细胞反应的途径，并可能引发下一代新型脱髓鞘预防、治疗或治疗策略和神经退行性疾病。
