YES
1. Analyzing the correlation between serum interferon activity and clinical manifestations, clinical course, prognosis, and treatment response in patients with anti-MDA5 antibody-positive dermatomyositis.
2. Investigating the MDA5 activation and interferon activation mechanisms induced by anti-MDA5 antibodies, and identifying the MDA5 antigen recognition sites.
3. Elucidating the inflammatory cytokine activation mechanism through the interferon-MDA5 pathway in anti-MDA5 antibody-positive dermatomyositis.

Pathophysiology
We will conduct an analysis of the correlation between serum interferon activity and clinical manifestations, hematological findings, severity of interstitial lung disease (ILD), and outcomes in MDA5-DM patients. Additionally, using various clinical indicators, we will perform latent cluster analysis to establish a novel disease classification by examining the association between disease subtypes and serum interferon levels.
The measurement of interferon will be performed using the WISH IFN bioassay (Genes Immun 2007;8:492), which allows for the detection of serum interferon activity at approximately 100 times the sensitivity of conventional ELISA. Furthermore, we will use the ultra-sensitive digital ELISA method for interferon detection.
