中文摘要

该项目旨在将单个抗原呈现给T细胞,并用单分子显微镜成像T细胞受体信号。将DNA折纸纳米技术与单分子成像相结合,应该可以揭示T细胞信号的敏感性。DNA力传感器将确定机械力是否有助于识别抗原。该项目将使用纳米技术策略来识别组织中的抗原特异性T细胞。该项目预计将促进对T细胞生物学的理解,并有助于DNA纳米技术和超分辨率显微镜,同时提供对T细胞识别抗原的基本见解,并最终获得临床相关的实际应用。
英文摘要
The project aims to present individual antigens to T cells and to image T cell receptor signalling with single molecule microscopy. Combining DNA origami nanotechnology with single molecule imaging should reveal the sensitivity of T cell signalling. A DNA force sensor will determine whether mechanical forces contribute to antigen discrimination. The project will use the nanotechnology strategy to identify antigen-specific T cells in tissue. The project is expected to advance understanding of T cell biology, and contribute to DNA nanotechnology and super-resolution microscopy whilst providing fundamental insights into antigen recognition by T cells and ultimately derive clinically relevant practical applications.
