Acetylcholinesterase (AChE or acetylhydrolase) is a serine hydrolase that terminates the action of the neurotransmitter acetylcholine by hydrolyzing it into acetic acid and choline. AChE is found at mainly neuromuscular junctions and cholinergic brain synapses, where its activity serves to terminate synaptic transmission. AChE plays an important role in the pathogenesis of neurodegenerative diseases by influencing the inflammatory response, apoptosis, oxidative stress and aggregation of pathological proteins.
