IL6 and asthma: In asthma, the highest IL-6 production after UPM treatment was noted in epithelial cells alone (34.33 pg/ml (5.77–57.26 pg/ml)) and in triple-co-cultures with moMφs (24 h UMP) (34.60 pg/ml (6.03–54.27 pg/ml)) compared to unstimulated triple co-cultures (5.63 pg/ml (2.94–11.74 pg/ml), p = 0.038 and p = 0.008, respectively).
