IFNG and Löfgren’s syndrome: The level of TIM-1 mRNA correlated positively with the level of IFN-γ in control subjects and in patients with Löfgren's syndrome (r = 0.83, p = 0.02; r = 0.68, p = 0.01; respectively, figures 3a, b), while no correlation in non- Löfgren's patients was observed (figure 3c).
