After stimulation with vimentin, the median IFN-γ concentration was significantly elevated in the supernatant of sarcoidosis (396.6 pg/mL IQR 0.1–657.1) vs. tuberculosis (0.1 pg/mL IQR 0.1–0.1, p = 0.0009) and healthy volunteer PBMCs (0.1 pg/mL IGR 0.1–0.1, p = 0.014) (Fig 5A). This evidence concerns the gene IFNG and sarcoidosis.
