糖生物学家研究发现,人体细胞表面密布着许许多多的糖缀合物——糖链,每个细胞表面大概都有50万条。它们犹如细胞间的无线通讯网,不但决定着细胞的类型,而且还肩负着细胞间的信息传递,在生物体中起着通讯、识别、调控的重要作用。糖链结构和功能的完整与否直接影响着基因获取外界变化信号的准确度。DNA若收到错误或不完整的信息后,所作出的指令必然失去针对性、甚至是错误的。例如,当有外源异物进入体内时,率先起监察作用的就是糖链,无论是移植的器官还是入侵的微生物与病毒,
Sugar biologists have found that there are many sugar conjugates - sugar chains on the surface of human cells, with about 500,000 cells on each cell surface. They are like the wireless communication network between cells, which not only determines the type of cells, but also carries information transmission among cells and plays an important role in communication, recognition and regulation in the organism. Sugar chain structure and function of the integrity of a direct impact on the outside world to obtain the signal changes in the accuracy of the signal. If the DNA receives the wrong or incomplete information, the instruction will inevitably lose its relevance or even be wrong. For example, when exogenous foreign bodies enter the body, the first to be monitored is the sugar chain, whether it is a transplanted organ or an invading microorganism and a virus,
