| Outline of Final Research Achievements |
In chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), development of axonal degeneration is known as a characteristic of refractory to immune therapy and long-term poor prognosis.
An animal model of CIDP, non-obese diabetic (NOD) mouse characterized by spontaneous chronic autoimmune neuropathy is known and we confirmed the histopathological findings of NOD mouse. Mild inflammatory cell infiltration was observed from around 20 weeks of age in NOD mouse, and exhibited highly inflammatory cell infiltration with active demyelination. After the infiltration of inflammatory cells declined, secondary axonal degeneration was observed.
