Sural nerve biopsies in Guillain‐Barre syndrome: Axonal degeneration and macrophage‐associated demyelination and absence of cytomegalovirus genome

Abstract excerpt

T-cell infiltration was detected by immunohistochemistry in only 2 of 10 sural nerve biopsies from patients with Guillain-Barré syndrome (GBS). The number of endoneurial macrophages, identified by the monoclonal antibody MAC 387, was increased, compared with the number in 10 cases of axonal neuropathy. Macrophage-associated demyelination was identified in 7 and axonal degeneration in 8 cases. Cytomegalovirus...
