Antibodies to sulfatide in cerebrospinal fluid of patients with multiple sclerosis.

The identity of target antigen(s) in multiple sclerosis (MS) remains elusive despite much effort to identify it. We analyzed cerebrospinal fluid (CSF) from patients with MS, other neurological diseases (OND), other diseases (OD) and healthy controls for antibodies against purified sulfatide, a major glycosphingolipid of human myelin, by an enzyme-linked immunosorbent assay (ELISA) and a thin-layer chromatogram (TLC)-immunostaining technique. Elevated anti-sulfatide antibodies were significantly higher in MS patients as compared with the OND group (p<0.
