We investigated serological immune responses against three major peripheral
nerve myelin constituents in patients with immune-mediated neuropathies. C
onnexin 32 (Cx32), myelin protein zero (MPZ. P-0) and peripheral myelin pro
tein 22 (PMP22) were produced in Chinese hamster ovary (CHO)-K1 cells. From
a panel of 25 Guillain-Barre syndrome (GBS) and 24 chronic inflammatory de
myelinating polyneuropathy (CIDP) patients, only two patients showed reacti
vity towards Cx32 and P-0. (C) 2001 Elsevier Science B.V. All rights reserv
