Now, west nile virus enters host cells using a lipid membrane protein called E2 in a process called clathrin-mediated endocytosis.

西尼罗河病毒利用脂质双分子层上的包膜蛋（E）通过网格蛋的吞作用进入宿主细胞。

Receptors are like keys, and if the virus has the right key, our cell will surround it -- called endocytosis.

受体就像钥匙， 如病毒有正确的钥匙，我们的细胞就会包围它——吞作用。

During the endocytosis process, the icosahedral capsid breaks open, allowing the single stranded RNA of Rhinovirus to gain access to the host cell cytoplasm.

在胞吞过程中，二十面体衣壳破裂，使鼻病毒的单链RNA能够进入宿主细胞的细胞质。

That happens through a process called endocytosis in which sections of the membrane engulf substances and transport them into the cell as vesicles.

这是通过吞作用的过程发生的，在该过程中，膜的一部分会吞噬物质并将它们作囊泡输送到细胞中。

Clathrin-mediated endocytosis is a cellular process that creates a vesicle to internalize a certain substance, in the case here, the virus, with the help of the proteins called clathrins.

网格蛋的吞作用是指通过形成小泡进入某种物质；这种情况下，病毒利用的是网格蛋。
