随后尼古丁控制了脑细胞受体，并释放出多巴胺——大脑中感觉良好的化学成分，能给人带来愉悦和舒适的感觉。
Then the nicotine grabs hold of receptors on brain cells and releases dopamine, the brain's feel-good chemical, bringing feelings of pleasure and comfort.
“据悉，有10至12尼古丁受体表达表面上的各种细胞，”陈博士解释。
"It has been known that there are 10 to 12 nicotine receptors that express on the surface of various cells," Chen explained.
我们不知道为什么尼古丁受体表达各种组织器官的所有细胞表面，但我们知道尼古丁是一个重要的神经递质在中枢神经系统。
We do not know why nicotine receptors express in all the cell surfaces from various tissue origins, but we do know that nicotine is an important neuron transmitter in the central nervous system.
