Abstract

One-thirds of patients develop Guillain-Barré syndrome subsequent to Campylobacter jejuni enteritis. Molecular mimicry exists between C. jejuni lipo-oligosaccharides and human peripheral nerve gangliosides GM1 and GD1a. IgG antibodies against GM1 or GD1a are produced in one out of 5,000 patients with C. jejuni enteritis. The autoantibodies bind to gangliosides at the nodes of Ranvier in the peripheral motor nerves and activate complement in situ. This is followed by the disappearance of the voltage-gated sodium channel clusters at the nodes and disruption of axo-glial junctions at the paranodes. This results in the development of motor nerve conduction failure and muscle weakness in the four limbs.
