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 [3] most of the Ab+ patients had C. jejuni infections. Patients with Anti-GalNAc-GD1a antibodies were less common but had more severe disease (rapidly ...
Antibodies to GM1 are increased in Guillain–Barré syndrome, dementia and lupus but their function is not clear. [4] There is some evidence to suggest antibodies against GM1 are associated with diarrhea in Guillain–Barré syndrome. [5] GM1 antibodies are also seen in Multifocal Motor Neuropathy (MMN), a rare antibody-mediated inflammatory ...
An example of such antibodies is hu14.18K322A, a monoclonal antibody. This anti-GD2 antibody is currently undergoing a phase II clinical trial in the treatment of previously untreated high risk neuroblastoma given alongside combination chemotherapy prior to stem cell transplant and radiation therapy .

A ganglioside is a molecule composed of a glycosphingolipid (ceramide and oligosaccharide) with one or more sialic acids (e.g. N-acetylneuraminic acid, NANA) linked on the sugar chain. NeuNAc, an acetylated derivative of the carbohydrate sialic acid, makes the head groups of gangliosides anionic at pH 7, which distinguishes them from globosides .
The remaining syllables of the INNs, as well as the column Source, are explained in Nomenclature of monoclonal antibodies. Types of monoclonal antibodies with other structures than naturally occurring antibodies. The abbreviations in the column Type are as follows: mab: whole monoclonal antibody; Fab: fragment, antigen-binding (one arm)
Signs and symptoms depend on the targeted antigen, but the features in patients with different antibodies often overlap. The most characteristic feature found in a case series was cognitive impairment and seizures in anti-LGI-1 positive patients, and peripheral motor hyperexcitability in anti-CASPR2 positive patients.
Myelin-associated glycoprotein (MAG, Siglec-4) is a type 1 transmembrane protein glycoprotein localized in periaxonal Schwann cell and oligodendrocyte membranes, where it plays a role in glial-axonal interactions.
Anti-rheumatoid factor antibodies are also increased. [95] In addition, cross-reactive anti-beef-collagen antibodies (IgG) may explain some rheumatoid arthritis (RA) incidences. [ 96 ] Although the presence of anti-beef collagen antibodies does not necessarily lead to RA, the RA association with Triticeae consumption is secondary to GSE and ...
