摘要：

We previously reported the selection of several families of phage-displayed peptide mimics (mimotopes) recognized by oligoclonal immunoglobulins present in the CSF of multiple sclerosis (MS) patients. To search for the natural antigens recognized by these antibodies, anti-sera were raised against one of the mimotopes and used as a probe in ELISA. Western blotting and immunoprecipitation experiments. Anti-mimotope IgG were found to cross-react with an epitope shared by a brain-specific factor conserved from rodents to humans, and the surface glycoprotein gB of HSV-I. These findings support the hypothesis that common viral infections are the triggering agents of self-reactive CSF antibodies, whose role in MS still remains to be elucidated.
