Clusters of acetylcholine receptors were formed in the absence of neurons during the development of cultured chick-embryo skeletal muscle cells. The average concentration of receptors in clusters was ...

The lack of this key tryptophan residue in the β3 subunit makes it the true homolog of the muscle β1 subunit that does not contribute to an agonist binding site. Certainly, the similarity in ...

It's here that neurons release a transmitter chemical called acetylcholine. These molecules bind to a protein receptor on the cells of muscles, triggering an opening in the cell membrane.

Acetylcholine is a neurotransmitter that plays a key role in brain and muscle function. Here, we look at what acetylcholine does and describe medical conditions linked with it, including Alzheimer ...

It mimics the action of acetylcholine at the nicotinic receptor, producing sustained depolarization of the muscle end plate, which causes fasciculations and subsequent flaccid paralysis.

In myasthenia gravis, abnormal antibodies reduce the number of receptors for acetylcholine on muscle cells. You need acetylcholine receptors for your muscles to function normally.

Another 5% to 10% test positive for anti-muscle-specific serum kinase (anti-MuSK) antibodies. The MuSK protein helps organize acetylcholine on the surface of muscle cells.
