Figure 4.
Northern blot autoradiograms of lysates of alveolar macrophages (AMs) and autologous peripheral blood–derived monocytes-macrophages cultured for 1 (PBMs-1) or 7 (PBMs-7) days that were sham-exposed or exposed to influenza A virus (IAV). Lysates were probed for influenza virus neuraminidase (NA) and the same lanes were probed subsequently for β-actin. All lanes are from the same Northern blot.
