Musk antibody

Muscle-specific kinase (MuSK) antibody is detectable in more than one-third of those seronegative for muscle AChR antibody (less than 4% of all patients). (3) Physiologically, MuSK is involved in integrating and stabilizing AChR clusters in the motor endplate. Anti‐MuSK antibodies interfere with agrin induced clustering of AChRs in cultured muscle cell lines. 1 It is unclear what effect anti‐MuSK antibodies will have on the more stable adult neuromuscular junction, and indeed there is some controversy over the pathogenicity of anti‐MuSK antibodies. 7 In patients with these antibodies there was no substantial loss of . Anti-muscle-specific kinase (anti-MuSK) antibodies are autoantibodies, proteins produce by the immune system that mistakenly attack proteins called muscle-specific kinases. This test detects these autoantibodies in the blood of people with myasthenia gravis (MG), a rare but often severe autoimmune disease that causes muscle fatigue and weakness.

MuSK Antibody Test - Detection of antibodies to muscle-specific receptor tyrosine kinase (MuSK) (titer test). Muscle-specific kinase (MuSK) antibody is detectable in more than one-third of those seronegative for muscle AChR antibody (less than 4% of all patients). (3) Physiologically, MuSK is involved in integrating and stabilizing AChR clusters in the motor endplate. Anti‐MuSK antibodies interfere with agrin induced clustering of AChRs in cultured muscle cell lines. 1 It is unclear what effect anti‐MuSK antibodies will have on the more stable adult neuromuscular junction, and indeed there is some controversy over the pathogenicity of anti‐MuSK antibodies. 7 In patients with these antibodies there was no substantial loss of . Antibodies directed against this protein (Anti-MuSK autoantibodies) are found in some people with myasthenia gravis not demonstrating antibodies to the acetylcholine receptor.
