Zusammenfassung
The role of IgG in effecting gastrointestinal (G.I.) dysmotility associated with neurologic autoimmunity (idiopathic or paraneoplastic) remains poorly defined. Serum IgG prepared from patients with anti-neuronal nuclear autoantibody type 1 (ANNA-1 [aka anti-Hu], n=7) or ganglionic nicotinic acetylcholine receptor (α3AChR, n=6) autoantibody were tested on myenteric neurons in longitudinal muscle myenteric plexus (LMMP) preparations from the ileum of 38 guinea pigs. IgG prepared from healthy subjects or neurologic patients (n=7) without G.I. symptoms served as controls. Action potential discharges in all neurons o…
