Antiganglioside antibodies that react to self-gangliosides are found in autoimmune neuropathies These antibodies were first found to react with cerebellar cells These antibodies show highest association with certain forms of Guillain–Barré syndrome

Antibodies to ganglioside subtypes

Autoantigenic gangliosides that are currently known are GD3, GM1, GQ3 and GT1

Anti-GD3

Anti-GD3 antibodies have been found in association with specific forms of Guillain–Barré syndrome In vivo studies of isolated anti-GM1 and GD3 antibodies indicate the antibodies can interfere with motor neuron function Anti-GD1a antibodies were highly associated acute motor axonal neuropathy while high titers of anti-GM1 were more frequent indicating that GD1a possibly targets the axolemma and nodes of Ranvier most of the Ab+ patients had C jejuni infections Patients with Anti-GalNAc-GD1a antibodies were less common but had more severe disease rapidly progressive, predominantly distal weakness

Anti-GM1

Levels of anti-GM1 are elevated in patients with various forms of dementia Antibodies levels correlate with more severe Guillain–Barré syndrome In Japan, levels to GM1 were elevated in patients with prodromal diarrhea Titers to GM1 in other diseases rheumatoid arthritis, primary Sjögren's syndrome and systemic lupus erythematosus was also elevated additionally highly significant association was found with rheumatoid arthritis and peripheral neuropathies Conflicting evidence suggests no significant elevation in motor neuron neuropathy but marginally elevated IgA in sensory neuron neuropathies The autoimmune role of anti-GM1 is still unclear Multifocal Motor Neuropathy MMN with conduction block is closely related to CIDP chronic inflammatory demyelinating polyneuropathy Anti- GM1 antibodies are positive in around 80% of cases MMN will present with asymmetrical motor neuropathy where reflexes are usually preserved or slightly elevated, affecting Upper limb more than Lower limb MMN is potentially treatable with immunomodulation

Anti-GQ1b

Anti-GQ1b are found in Miller-Fisher syndrome This presents with the classical triad of ataxia, areflexia and ophthalmoplegia Studies of these antibodies reveal large disruption of the Schwann cells Anti-GQ1b IgG levels were elevated in patients with ophthalmoplegia in Guillain–Barré syndrome

Triggering agents

Microbial agents include: Campylobacter jejuni and Mycoplasma pneumoniae

Campylobacter jejuni

Antibodies to a GM1 epitope as well as to one with the GT1a or GD3 epitope were found in different strains of Campylobacter jejuni and patients with Guillain–Barré syndrome have a high occurrence of C jejuni infection Many studies indicate that C jejuni may be causative for a subset of some forms of neuropathies

Coeliac disease

Antibodies to ganglioside are found to be elevated in coeliac disease Recent studies show that gliadin can cross-link to gangliosides in a transglutaminase independent manner, indicating that gliadin specific T-cell could present these antigens to the immune system

Immunoglobin isotypes

IgG In multiple sclerosis, antibodies to GM1 are dominated by the IgG1, IgG3 and IgG4 Also anti-GM1 IgG has been identified in Guillain–Barré syndrome or chronic inflammatory demyelinating polyradiculoneuropathy while controlled studies failed to find any significant association with Motor neuron disease
IgA IgA to gangliosides have been observed in Guillain–Barré syndrome
IgM IgM antibodies have been detected in early work, but their significance in disease is controversial
