<unk>  is thought to be caused by alterations in the immune system, such that certain proteins (antibodies) that would normally protect one from viruses and bacteria begin to attack constituents of peripheral nerves. Antibodies may be directed against “GM-1”, a ganglioside found at the Nodes of Ranvier. These antibodies have been detected in at least one-third of<unk>  patients. More recent studies also suggest that newer tests for antibodies directed against GM-1, as well as a number of related gangliosides, are positive in over 80% of<unk>  patients. There are increasing reasons to believe these antibodies are the cause of<unk> .
