Figure 1From: The TGF-beta-Pseudoreceptor BAMBI is strongly expressed in COPD lungs and regulated by nontypeable Haemophilus influenzae In situ hybridization targeting NTHI in persistently infected COPD lung tissue. AM (A, 400×; B, 600×), AEC (C, 600×) and bronchial epithelial cells (D, 600×). AM = alveolar macrophages, AEC = alveolar epithelial cells. Aminoethylcarbazole was used as a color substrate, which results in red signals. Signals are also indicated by arrows.Back to article page
