这个项目旨在研究T淋巴细胞是如何被皮肤相关抗原呈递分子CD1a提供的脂质激活的。使用X射线结晶学和细胞免疫学,我们将提供对这一鲜为人知的免疫轴的基本见解。我们将确定CD1a如何呈现不同的自身和异体脂质的分子基础,以及这些CD1a-脂质复合体如何被反应的T细胞识别。这一基础科学发现项目将在新兴的脂质介导免疫领域提供大量新知识,最终将导致针对CD1a脂质展示分子的新疗法,以防止免疫中介损害或根据需要促进保护性免疫。
英文摘要
This project aims to investigate how T lymphocytes are activated by lipids presented by the skin-associated antigen-presenting molecule, CD1a. Using X-ray crystallography and cellular immunology, we will provide fundamental insight into this poorly understood immunological axis. We will determine the molecular basis for how CD1a presents diverse self and foreign lipids, and how such CD1a-lipid complexes are recognised by the responding T cells. This basic science discovery project will provide substantial new knowledge in the burgeoning field of lipid-mediated immunity, which should ultimately lead to new therapies targeting the CD1a lipid display molecule to either prevent immune mediated damage or promote protective immunity as required.
