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。

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。

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。
