Myasthenia gravis is a type II hypersensitivity disorder where the body produces antibodies that most commonly target nicotinic acetylcholine receptors on the surface of muscle cells.

重症肌无力是一种II型超敏反应，身体产生抗体，常见靶点为肌肉细胞表面的N胆碱受体抗体。

Once nicotine is absorbed into the bloodstream, it binds to a type of acetylcholine receptor, called a nicotinic acetylcholine receptor - also called a nicotinic receptor - which is found throughout the body and brain.

一旦尼古丁进入血液循环，它就会和一种乙酰胆碱受体结合，也称烟碱型乙酰胆碱受体或烟碱受体；这类受体广泛分布于身体和大脑中。

COREY ALLARD: They didn't resemble known sensory  receptors instead they're most closely related to a family of receptors called  nicotinic acetylcholine receptors.

COREY ALLARD：它们不像已知的感觉受体，相反，它们与称为烟碱乙酰胆碱受体的受体家族关系最密切。
