该项目旨在研究T淋巴细胞如何被皮肤相关抗原呈递分子CD 1a呈递的脂质激活。 使用X射线晶体学和细胞免疫学,我们将提供基本的洞察力,这知之甚少的免疫轴。我们将确定CD 1a如何呈现不同的自身和外来脂质的分子基础,以及这种CD 1a-脂质复合物如何被响应的T细胞识别。这个基础科学发现项目将在新兴的脂质介导的免疫领域提供大量的新知识,这将最终导致靶向CD 1a脂质展示分子的新疗法,以预防免疫介导的损伤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.
