FIG 6.

NiV-B-induced human neutrophil migration to human lung interstitium from reconstituted mice. Shown is myeloperoxidase (brown signal) in NiV-B-infected (a) and mock-infected (b) human lung graft sections from reconstituted mice at day 3 postinfection. Neutrophils (a and b) in lumen of the small airways/alveolar area and in large perivascular infiltrations (a) are shown. Syncytium formation is indicated by arrows. This was observed regardless of the donor. Original magnifications, ×10. Original magnifications of windows, ×40. Bars, 100 μm.
