| Research Abstract |
Diagnostic biomarker in systemic juvenile arthritis (sJIA) remains to be elucidated. An exploration of disease-specific marker in sJIA was conducted with a native PAGE-combined 2-DE. Peptide mapping with sera form 4 sJIA patients revealed several spots such as iron-related proteins, lipoproteins, complements, globulin-related molecules, which were similar in profiling pattern to the control samples from febrile patients. Haptoglobin 2-2 genotype was uniformaly detected in sJIA sera. A unique transthyretin-combined protein complex was also profiled in sJIA sera. These results might be a breakthrough in establishing sJIA-specific biomarker.
