We herein tested for autoantibodies against neurofascin (NF) 155, NF186, contactin-associated protein 1 and contactin-1 and investigated the autoantibody-related clinical features in 29 patients with CIDP from China.
Antibodies to Contactin-1 and Neurofascin 155 (Nfasc155) have recently been associated with subsets of patients with chronic inflammatory demyelinating polyneuropathy (CIDP).
Additionally, during this time a series of experimental studies have unraveled the underlying immunopathogenesis for CNTN1 and NF155 antibody associated CIDP.
Assessment of longitudinal sections by electron microscopy revealed that detachment of terminal myelin loops from the axolemma was frequently found at the paranode in patients with anti-neurofascin-155 and anti-contactin-1 antibody-positive CIDP compared with patients with antibody-negative CIDP.
