FIGURE 38-2: Molecular mimicry in GBS. Campylobacter sialyltransferase activity determines the neuropathy subtype. Campylobacter jejuni with the cstII allele Thr51 have α2,3-activity and produce GM1 and GD1a-like LOS structures, which induce the production of anti-GM1 and anti-GD1a antibodies, resulting in AMAN. C. jejuni strains possessing the Asn51 allele have bifunctional enzyme activity and produce GT1a and GD1c-like LOS structures with terminal disialosyl groups, which induce the production of anti-GQ1b, GD3, and GT1a antibodies, resulting in MFS. AMAN, acute motor axonal neuropathy; C. jejuni, Campylobacter jejuni; GBS, Guillain–Barré syndrome; LOS, lipo-oligosaccharide; MFS, Miller Fisher syndrome. {} = ganglioside mimicking structure of LOS.
