Figure 2From: The TGF-beta-Pseudoreceptor BAMBI is strongly expressed in COPD lungs and regulated by nontypeable Haemophilus influenzae In situ hybridization targeting NTHI in in vitro infected human lung tissue (Aminoethylcarbazole, red signals). Signals are also indicated by arrows. Positive staining of AM (A, 400×), AEC (B, 400×) and bronchial epithelial cells (C, 400×), control (D, 400×). NTHI-1 infection was primarily detected in AM (figure a) and to a lesser degree also in AEC (figure 2b). Similar results were seen with NTHI-2 (demonstrated for AM [E, 600×], control [F, 600×]). AM = alveolar macrophages, AEC = alveolar epithelial cells.Back to article page
