The median IFN-γ concentration was significantly elevated in the cell culture supernatant of PBMCs from patients with active pulmonary sarcoidosis (Table 1) stimulated with sKv (207.2 pg/mL, IQR 65.94–416.1) compared to either healthy control PBMCs stimulated with sKv (3.86 pg/mL, IQR 0.1–22.32, p = 0.0018) or sarcoidosis PBMCs stimulated with cKv (0.1 pg/mL IQR 0.1–4.37, p<0.0001) as seen in Fig 1A. This evidence concerns the gene IFNG and pulmonary sarcoidosis.
