Reactivity against rat DRG neurons and human neuroblastoma-derived neurons. DRG neurons (A, B) stained with a GBS patient’s serum reacting moderately (score 2) in IgG (A), and a GBS patient’s serum reacting strongly (score 3) in IgM (B). Human neuroblastoma-derived neurons (C, D) stained in red with anti-panNeurofascin mAb, and in green with a GBS patient’s serum reacting moderately (score 2) in IgG (C) and a GBS patient’s serum reacting strongly (score 3) in IgM (D)
