Modulation of fresh AECII phenotype by IFN-γ and/or TNF-α (in percentage). AECII were treated as was A549 cell line in Figure 2. Four independent experiments were performed in triplicate, each point representing the mean value. The bars represent the medians. Results were compared to their resting conditions. I100: IFN-γ 100 ng/ml; T50: TNF-α 50 ng/ml; I50/T25: IFN-γ 100 ng/ml, TNF-α 25 ng/ml.
