Figure 7

(A) Normal, (B) Untreated, (C) AF2240-i-treated and (D) rAF-IL12-treated. Normal, untreated and rAF-IL12-treated groups showed normal alveolar morphology; alveolar air space (green arrow) and alveolar capillary (yellow arrow). AF2240-i treated group showed normal alveolar morphology; alveolar air space (green arrow) and alveolar capillary (yellow arrow) but with mild thickening of the alveolar interstitial wall due to leucocytic infiltration (blue arrow). Magnification: 100X; H&E scale bar = 200 µm.
