Normally, the liver and kidneys produce a tiny hormone called thrombopoietin which binds to hematopoietic cell receptors.

正常情况下，肝脏和肾脏会合成一种叫做促血小板生成素的激素，可以与造血细胞受体结合。

Now, scientists have identified a single blood cell receptor that Plasmodium absolutely needs to enter the blood cell.

如今，科学家确认了一种疟原虫进入血细胞所必须的感受器。

Once they reach your respiratory lining, the viruses attach to a specific kind of cell receptor, called sialic acid.

一旦病毒进入你的呼吸系统，就会附着在一种叫做唾液酸的特定细胞受体上。

Retinoids work by binding to skin cell receptors to remove dead skin cells and encourage healthy skin cell growth.

类维生素A通过与皮肤细胞上的受体结合，移除死细胞，促进健康细胞生长。

But if that hydrophobic region helps human insulin bind to our cell receptors, how would this insulin manage it?

但是， 如果那个疏水区域帮助人类胰岛素与我们的细胞受体结合，那么这种胰岛素将如何管理它呢？

The endocrine system relies on interactions between three features to do its job: glands, hormones, and trillions of cell receptors.

内分泌系统依靠三种功能之间的相互作用来完成其工作：腺体、激素和数万亿个细胞受体。

Antibodies, are just the B cell receptor in a secreted form, so they can circulate in serum, which is the non-cellular part of blood - attaching to pathogens and tagging them for destruction.

抗体，就是分泌型的B细胞受体，所以它们可以在血清（血液除去细胞的部分）中循环，附着在病原体上并标记以进行破坏。
