One of the other things that MHC1 does, in addition to marking yourselves as your own, is that it's capable of making combinations with all the different molecules that are present inside the cell and expressing them on the surface, and sort of showing them to the outside world.

HC1的另一项功能,除了给你标记一个独一无二的标签以外,MHC可以和细胞内所有不同的,分子结合 使其能够呈现在细胞表面,使其暴露于外界
