Research Abstract |
For the specific and quick diagnosis of paraneoplastic neurological syndromes, we produced several recombinant antigen proteins (Yo/Hu/Ri/CRMP-5,/Ma-2) and used as antigens for western blot or ELISA. We analysed the frequency of these antibody positivity among 1500 samples which sent us for the diagnosis of paraneoplastic neurological syndromes. We found anti-Yo antibody in 1.5% of these sera and anti-Hu antibody in 2.3%. For those with specific antibody-positive patients, we analysed the HLA type under the informed consent, and found the similar amimo acid motifs in their class I molecules, which would be used as the targets for cytotoxic T cell assay.
