Demyelinating diseases such as multiple sclerosis or the Guillain-Barré syndrome originate from an autoimmune response resulting in the degradation of myelin and impaired neuronal function. Prophylactic administration of the neurotrophic peptide, H-Met(O2)-Glu-His-Phe-D-Lys-Phe-OH (an ACTH(49) analogue), to rats with experimental allergic neuritis, a model for the Guillain-Barré syndrome, markedly suppresses the clinical symptoms, protects against loss of motor coordination and prevents the degeneration of myelinated axons in the affected peripheral nerve. Therefore, this peptide may provide a new approach to the therapy of peripheral demyelinating polyneuropathies.
