✦ Synopsis


Antibodies to GM 1 ganglioside are found in some patients with the Guillain-Barre Β΄syndrome and multifocal motor neuropathy, and may alter neuronal excitability. We measured voltage-gated sodium channel (VGSC) function by 22 Na + influx in a motor neuronal cell line (NSC19) in which we demonstrated GM 1 ganglioside and tetrodotoxin-sensitive VGSC function. We were unable to detect any effect of peripheral neuropathy plasmas, with or without complement, on VGSC function in NSC19 cells.

## Abstract This study examined the loss of voltage‐gated Na^+^ channels as well as acetylcholine receptors (AChRs) form the endplate region in patients with acquired myasthenia gravis (MG) and in rats with experimental autoimmune passively transferred MG (PTMG). Rats received a monoclonal IgG anti
