High acetylcholine receptor antibodies
WebWhat 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 current that triggers … WebAcetylcholine receptor antibodies are the main pathogenic agent in myasthenia gravis, a neurological disorder resulting in weakness and fatigability of voluntary muscles. The antibodies can be measured by a radioimmunoprecipitation assay, which is in use throughout the world and provides a diagnostic test of high sensitivity and specificity.
