Percentage of patients with juvenile idiopathic arthritis (JIA) and healthy controls showing positive T-cell proliferative responses. Transparent bar: 2 ≤ stimulation index (SI) < 3; black bar: 3 ≤ SI < 4; gray bar: SI ≥ 4. The highest frequencies were found for the peptides derived from aggrecan, fibrillin, and matrix metalloproteinase (MMP)-3.
