Anti-AChR antibodies

Anti-AChR antibodies are proteins that the immune system mistakenly produces, targeting acetylcholine receptors (AChRs) on muscle cells. Acetylcholine is a chemical that helps send signals from nerves to muscles, enabling movement. In conditions like myasthenia gravis, these antibodies block or destroy AChRs, leading to muscle weakness and fatigue. This disruption hampers effective communication between nerves and muscles, resulting in difficulty with activities like lifting objects or maintaining posture. Detecting these antibodies can help diagnose and manage related disorders, guiding treatment decisions to improve muscle function and overall quality of life.
