Outline of Final Research Achievements |
Interaction between axon and myelin sheath has a crucial role for the maintenance of the peripheral nervous system. We have clarified that TAG-1, which specifically distributes on juxtaparanode, ameliorates the remyelinating process depends on non-synonymous amino acids changes through SNPs. In this study, we produce an experimental autoimmune neuritis model by inducing myelin-origined peptides with complete Freund adjuvant. This mice showed inflammatory demyelination followed by severe axonal degeneration. TAG-1 could work as a trigger for remyelination after demyelination. In addition, dysfunction of juxtaparnodal molecules would bring severe irreversible pathogenesis as like axonal degeneration.
