Outline of Final Research Achievements |
MDA5 is a cytoplasmic receptor that recognizes viral RNA and induces type I interferon (IFN)-based immunity. Autoantibodies against MDA5 are found in juvenile dermatomyositis with interstitial pneumonia, but serum MDA5 has not been investigated. In this study, soluble MDA5 was confirmed in serum in some patients with juvenile dermatomyositis and systemic lupus erythematosus by ELISA. MDA5 and IFNα increased in the same cases, suggesting that serum MDA5 may be involved in the pathophysiology of dermatomyositis, type I IFN is thought to play an important role in pathology.
