Neurotoxins dopamine receptors

A family of presynaptic ion channel-type acetylcholine receptors in the brain modulates the release of acetylcholine, dopamine, and other neurotransmitters implicated in learning and memory processes (37). There is convincing evidence to implicate a deficit in nicotinic receptors in the symptomatology of Alzheimer s disease. Furthermore, the neurotoxin /3-amyloid attenuates nicotine-induced release of acetylcholine and dopamine (37).
