An enzyme called acetylcholinesterase cleaves the ester bond in acetylcholine to generate choline and acetic acid, which are no longer able to bind to acetylcholine receptors. Rapid clearance of neurotransmitters such as acetylcholine is cr...

During neuromuscular junction formation ACh receptors accumulate at the nerve-contact region. ... ACh receptors were stained with tetramethyl rhodamine conjugated alpha- bungarotoxin. The cells were then treated briefly with Con A, and neural tube cells were added to these cultures. The mobility of ACh receptors was...

Acetylcholine (ACh) is the neurotransmitter at postganglionic nerve endings in the parasympathetic nervous system, ... Sidell and Hurst, 1997). AChE prevents ACh from accumulating after its release as a chemical messenger at the nervous system’s cholinergic synaptic junctions (Perrotta, 1996; Lefkowitz et al., 1990;
