美国威斯康星大学 ( UWI)的研究者已发现肉毒毒素如何阻止神经元中的神经递质释放 ,但尚不知毒素如何首先进入神经元。不管是吸入还是注入 ,毒素直接朝向神经元。毒素通过与神经元表面的受体结合 ,能被带入细胞 ,进而阻止神经递质的释放。　　UWI的研究者发现神经节苷脂和蛋白 Researchers at the University of Wisconsin (UWI) have discovered how botulinum toxin prevents the release of neurotransmitters in neurons, but it is unknown how toxins first enter neurons. Whether inhaled or infused, toxins directly target neurons. Toxins can be introduced into cells by binding to receptors on the surface of neurons, thereby preventing the release of neurotransmitters. UWI researchers have found that gangliosides and proteins
