| Research Abstract |
We analyzed 46 serum samples from neuropathy patients with IgM M protein for anti-glycolipid antibody testing. Serum IgM antibodies against GDlb and SGPG were measured by ELISA. We searched for a new IgM antibody to human brain protein by Western blot. Five were positive for anti-GDlb IgM antibody and 30 for anti-SGPG. Among 13 negative for anti-GDlb and anti-SGPG IgM antibody, 4 were positive for 40 kDa protein. This antibody more frequently was detected in neuropathy patients with IgM M protein than in each neurological disease control. We suggest that the 40kDa protein could be a target molecule for specific autoantibody in neuropathy with IgM M protein.
