Average IL10 protein levels detected 24 h after AF2122/97 infection were reduced from 3.3 Biological Units (BU)/ml by untreated bMDM to 2.6 BU/ml (p = 0.026), 1.9 BU/ml (p < 0.001) and 1.5 BU/ml (p < 0.001) by bMDM treated with 50 pg/ml, 500 pg/ml and 5,000 pg/ml IFNG, respectively (Fig 1B). Here, IFNG is linked to infection.
