WitrynaWhat do Acetylcholine Receptor (AChR) Antibodies do? At the normal neuromuscular junction, a nerve cell tells a muscle cell to contract by releasing the chemical acetylcholine (ACh). ACh attaches to the ACh receptor — a pore or “channel” in the surface of the muscle cell — twisting it open and allowing an inward flux of electrical ... WitrynaPresynaptic α7 nicotinic ACh receptors at immature glutamatergic synapses, activated via diffusion of ACh from nearby cholinergic terminals, may facilitate glutamate release at these terminals and consequently help mediate maturation of these synapses . The auditory system is also involved with the cholinergic system of the brain in an ... WitrynaIn human sperm, there also appears to be a role for a nicotinic acetylcholine receptor (nAChRs). One of the actions of ZP3 is to stimulate glycine receptors (GlyRs), and this causes a small depolarization that contributes to the early signal transduction step during the acrosome reaction. chuchero png
