The inhibitory effect of rhIFN-α 2a on IL-17 production from PBMCs from CAHB patients (n = 61) and healthy controls (n = 32). PBMCs from CAHB patients (n = 61) and healthy controls (n = 32) were cultured with or without rhIFN-α 2a at a concentration of 1 × 106 cells/ml in combination with anti-CD3 (5 mg/ml) and anti-CD28 anti- bodies (1 mg/ml) for 72 h. IL-17 production in the supernatant of cultured PBMCs was measured by ELISA. Columns represent meanvalues (mean + SEM).
