Guillain-Barré syndrome (GBS) and Miller Fisher syndrome (MFS) are acute immune-mediated neuropathies, often preceded by an infection. Anti-glycolipid antibodies are frequently detected in patients’ sera in the acute-phase. In particular, IgG anti-GQ1b antibodies are positive in as high as 90% of MFS cases. Anti-glycolipid antibodies are useful for the diagnosis of GBS and MFS. In addition, those antibodies may be directly involved in the pathogenetic mechanisms by binding specifically to the regions where the target glycolipid antigen is densely localized. This was proven by the development of animal models of anti-glycolipid antibody-mediated neuropathies. The presence of antibodies that specifically recognize a new conformational epitope formed by two gangliosides (ganglioside complex) in the acute-phase sera of some GBS patients suggested existence of a carbohydrate-carbohydrate interaction between glycolipids. Further intensive research is needed to clarify this point.
