That's making the cell look foreign because some of that foreign protein is on the surface with MHC1.
这使得整个细胞亦被视为外源物,因为某些外源蛋白,和MHC1共同出现在细胞表面
-
An alternate way is to go to the cell that's making the protein that you want.
另一种方法是,找到制造你想要的蛋白质的细胞
-
All the cells in your body have the capability of making all the proteins that you make, but they're not all made in every cell.
你体内的所有细胞,都有表达体内所有种类的蛋白的能力,但细胞并不会表达所有的蛋白质
-
When I talked about mitosis, I talked about cells making perfect copies of each other, so each parent cell becoming two daughter cells that are the same.
我讲有丝分裂的时候,谈到过细胞能够完美的复制自己,母细胞分裂成为,两个完全一样的子细胞
-
You want decisions to be made there so you need some additional mechanism for decision making at the point of contact between the axon of one cell and the dendrite of another.
而想要做出决定,在一个细胞的轴突和下一个细胞的树突,的连接点上 需要额外的决策机制
-
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
-
The important concept is that, while every cell in your body has the capability of making all the proteins that are needed throughout your body, not every cell is doing that at any given time.
这里面有一个重要的概念,就是尽管你身体里的细胞都,有能力制造出,全身上下所需的所有蛋白质,但不是所有细胞每时每刻都在这么做
-
These are two examples I just gave you of introducing genes that affect the life of a cell, either by making it express a protein that it's not making properly that's important to its life, or by intentionally killing a cell by having it express a fatal gene.
刚才我所举两个例子,都只是影响单一细胞生命过程的,无论是使无法正常表达的重要蛋白,正常表达也好,或是有意地,导入致命的基因杀死细胞也好
-
Well, that anti-sense strand is shown here as the red and the cell is naturally making the blue or sense strand of messenger RNA for a particular protein.
好的,反义链在这里以红色表示,细胞自身会造出合成某种,特定的蛋白质的蓝色RNA正义链
-
So, when the right signal is received, the right T-cell finds your host cell with a foreign virus in it, the first thing that happens is that this T-cell becomes activated and it starts reproducing, making more copies of itself.
所以 当接收到正确的信号,恰当的T细胞寻觅到,感染外源病毒的细胞时,首先发生的是,T细胞被激活并开始增殖,制造更多自身拷贝
-
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
