Peripheral nerve ultrasound in amyotrophic lateral sclerosis phenotypes.

abstract：:Sera of patients with myasthenia gravis (MG) contain anti-acetylcholine receptor (AChR) IgG antibodies (Ab) which have different antigenic specificities. Three Ab types were detected: (1) MG-I, which forms immune complexes with AChR; (2) MG-C, which decreases binding of AChR to concanavalin A; and MG-B, which blocks a...
