Histopathology The AVTGFb1 vector transduced active TGF b1 at con centrations of 106, 107, 5 ? 107, 108 and 109 pfu. The mice have been sacrificed at four, 7, 14 and 28 days after viral instillation. Dynasore Controls have been treated with saline or with vector alone at 5 ? 107, 108 and 109 pfu concentrations. Only 109 pfu is illustrated. The PBS treated animals have been regular at every time point. The mice treated with manage vector alone exhibited slight infiltration around a handful of little vessels and bronchi oles only at 7 days after therapy. Day four At day four, the tissues from mice receiving 106 and 107 pfu doses appeared fully regular, i. e. a histopathological score of 1 or less.
The 5 ? 107 Haematopoiesis and 108 pfu doses induced minimal modifications using a couple of cellular infiltrates. By day four, the 109 dose had triggered clear accumul PluriSln 1 ations of inflammatory cells in peribronchiolar and perivascular compartments. Alveolar walls have been thickened by inflammatory cells in addition to a fibro proliferative process. It was clear that the alveolar walls closest to the terminal bronchioles have been more severely affected, indicating a dose response of TGF b1 expression in situ as the insufflated fluids spread along the bronchiolar and alveolar surfaces as well as the virus infected the epithelial cells. trichrome staining. Blinded scoring in the histopathological At day 7 after therapy, the manage vector alone, even at 109 pfu, was primarily regular except for mild SC144 peri vascular and peribronchiolar inflammatory cell accumula tion. 106 pfu triggered no apparent illness.
In comparison, 107 pfu induced PluriSln 1 extremely mild interstitial illness that was recognized by blinded scoring in the histopathology in 3 in the nine animals evaluated. 5 ? 107 pfu made clear, diffuse fibroproliferative illness with cellular infiltra tion and thickened alveolar walls in each mouse studied. 108 and 109 induced severe fibroprolifera tive lung illness with obliteration in the alveolar architec ture in the most severely affected regions. An inset in Figure 3 shows BrdU incorporation in a bronchiolar wall and adjacent interstitium, and an inset in Figure 3 illustrates the improvement of fibrosis by sections confirmed the dose response reaction to TGF b1 expression. The 109 dose proved to become lethal for 45% in the mice by 8 9 days.
