title: Acute canine idiopathic polyneuropathy (ACIP) serum demyelinates peripheral nerve in vivo.
abstract: We examined the in vivo demyelinating activity of serum from dogs with acute canine idiopathic polyneuropathy (ACIP), a Guillain-Barré syndrome (GBS)-like illness. Sera from 6 ACIP cases demyelinated rat sciatic nerves more intensely than 11 control sera. Serum activity increased after guinea pig serum (gps) was added, although gps alone had little effect. ACIP sera did not bind more to whole nerve cross sections or Schwann cells in vitro than control sera, and did not contain elevated antigalactocerebroside titers. We do not as yet know the pathogenic importance of the demyelinating factor in ACIP and control dog serum, or understand its relationship to the demyelinating constituent in serum from humans with GBS.
