They're small molecules that - whose principal function in the body is to carry signals from one cell in the nervous system to another.

它们都是小分子,在体内主要功能是在,神经系统内将信号,从一个细胞传导到另一个细胞

They're not responsible necessarily for moving molecules inside and out, but they sit at the outside of the cell and they wait for signals.

它们不负责将分子运进运出,而是冲着细胞外面坐等信号

This is, maybe, the strangest because the ligand that stimulates the receptor is produced by the cell itself; so sometimes cells make signals that they receive.

它可能是最奇特的,因为激活受体的配体,是由细胞自身产生的,有时细胞产生让自己接受的信号

It's collecting information from all these dendrites under the right series of signals the cell body integrates all that information, says time for me to fire an action potential.

神经收集所有树突送来的,通过一系列正确信号传来的信息,细胞体整合所有信息之后,就到了发出动作电位的时候了

Sometimes signals are transmitted between cells by cell/cell contact.

有时细胞与细胞靠互相接触进行信号传递

Cells share signals with each other, and that leads to activation of a specific cell population if we're thinking about a vaccine that produces antibodies, that leads to activation of B-cells, immature B-cells, which do two things.

细胞与细胞之间存在信号传递,而这将激活特定的细胞群体,如果是一些能够产生抗体的疫苗,抗体将会激活B淋巴细胞,幼B淋巴细胞,使其发生两种变化
