When they do find the cell they're capable of interacting with the receptor forming some kind of chemical interaction with the receptor.

但当它们遇到细胞时,就能够与受体相互作用,与受体发生化学反应

So, it interacts with receptors called insulin receptors that are on cells that are sensitive to insulin.

它与细胞表面胰岛素受体相互作用,这些细胞对胰岛素很敏感

It does that through a complex set of sort of cellular interactions, and it turns out also gene rearrangements if you go further to study that.

而这此过程中,发生了一系列复杂的细胞间的相互作用,也会涉及到基因重排,如果你们深入学习的话就会学到

That infection occurs because of a ligand receptor interaction on the cell surface where the virus itself is the ligand and it takes advantage of a receptor that's expressed on the cell surface.

感染的发生是由于,配体与细胞表面受体相互作用,病毒是配体,它利用了在,细胞表面表达的受体

It's the way, for example, that foreign molecules or antigens get presented to cells of your immune system in order to start the process of making an immune response, so sometimes a cell/cell interaction.

通过这种方式,外源分子,或者说抗原,进入到免疫系统的细胞中后,就会开启免疫反应过程,有时候就是细胞之间的相互作用
