Compared to HCs, serum from patients with sarcoidosis significantly (p < 0.05) induced the expression of FCGR1B and IFIT2, whereas serum from patients with TB significantly (p < 0.05) reduced the expression of GBP1, SERPING1, and UBE2L6 compared to HCs (Supplementary Fig. 1B–D,G,I). This evidence concerns the gene SERPING1 and sarcoidosis.
