  • Title: [Antiglycolipid antibody in inflammatory neuropathy].
    Author: Kusunoki S.
    Journal: Rinsho Shinkeigaku; 1995 Dec; 35(12):1370-2. PubMed ID: 8752399.
    Abstract:
    Antiglycolipid antibody is frequently detected in the acute phase sera from patients with acute inflammatory demyelinating polyneuropathy (Guillain-Barré syndrome, GBS). The titer is highest in the serum sample taken first after the neurological onset, and decreases with clinical improvement. Antiglycolipid antibody may play a role in the pathogenetic mechanism of GBS. GM1 and GD1b are the antigens most commonly recognized. Monoclonal anti-GD1b antibody specifically bound to the paranodal myelin of the peripheral nervous system. Serum anti-GD1b antibody may cause demyelinative neuropathy by binding to the paranodal myelin of the peripheral nervous system. Anti-GQ1b IgG antibody is specifically raised in almost all the sera from Fisher syndrome and GBS with ophthalmoplegia. Anti-GQ1b monoclonal antibody immunostained specifically the paranodal myelin of the extramedullary portion of oculomotor, trochlear and abducens nerves, but no such staining was observed in the other peripheral nerves. Anti-GQ1b antibody may cause conduction block in the cranial nerves innervating the muscles for extraocular movement by binding to the paranodal myelin of those nerves. Anti-GalNAc-GD1a antibody is detected in the patients with GBS with very low or inexcitable compound muscle action potentials. The sera from patients with GBS subsequent to mycoplasma infection had antigalactocerebroside antibody. Further study on antiglycolipid antibody is needed for understanding the pathogenetic mechanism of GBS.
