What insulin is doing inside your body is acting as a ligand for insulin receptors which stimulate certain kinds of cellular responses.
胰岛素在体内的功能就是作为,胰岛素受体的配体,刺激产生某种细胞效应
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
During development of the embryo it goes from being a single cell, the fertilized egg, to being a multi-cellular organism with billions of cells in it.
胚胎的发育,始于一个单一细胞,即受精卵,直到形成一个以十亿计数量的细胞构成的,多细胞有机体
We can even understand it on a molecular or cellular level now.
如今我们已经能从,分子和细胞水平对机体进行研究
There's a couple of features of cellular physiology which are shown here.
这里展示了,一些细胞生理学的要点
We'll talk a little bit about the principles of cellular physiology and then I'll move next time to talking about how you culture cells outside of the body and what that's useful for.
这节课我们讲一些,细胞生理学的一些原理,下节课具体讲,体外培养细胞的方法,及其用途
Usually the cellular means that they get rid of is that instead of an antibody being produced, you activate a population of cells that will specifically go and hunt down the foreign antigen, or more commonly, cells that contain the foreign antigen.
通常细胞免疫意味着,不用生成抗体就能清除抗原,你激活了一个细胞类群,这一类群能够,并杀伤外源抗原,或者更常见的是,杀伤含有外源抗原的细胞
The other part of the adaptive immune system is the cell mediated immune system and this is an immune where that doesn't involve antibodies but involves cells that are activated in response to a foreign antigen and that utilize cellular means to get rid of it.
