| 英文摘要 | To effectively enhance affinity of T cells to lymphoma cells and improve its cytotoxicity, we describe a paired bioorthogonal strategy for labeling of glycans in tumor cells and active T cells through metabolic process of unnatural sugars containing bicycle [6.1.0] nonyne (BCN) or azide motifs, respectively. The new bifunctional unnatural sugars, especially BCN-Man, have been developed for efficient and nondestructive incorporation of the chemical reporters into wide cellular surface glycans, where the BCN motif exhibited an excellent bioorthogonal targeting and rapid reaction rate. Next, the complementary functional groups (-N3 / -BCN) were successfully incorporated into active T cells and B lymphoma cells through glycometabolic engineering of Ac4GalAz and BCN-Man, respectively. Subsequently, the results of cell binding assay showed that complementary functional group modification remarkably enhanced the targeting and migration of T cells for lymphoma cells. Simultaneously, we also found that the cytotoxicity of azido T cell against BCN-lymphoma cell increased by 2.7 times, when compared to the unlabeled control cells. These results demonstrated the promising potential of based complementary bioorthogonalglycometabolic labeling for various applications ranging from T cell immunotherapy in clinical to studying cell-cell interactions in vivo |
