Figure 1. — (A–C). Twist1 in human alveolar macrophages. Twist1 mRNA expression is intrinsically elevated in alveolar macrophages of sarcoidosis patients compared to healthy controls (A); Immunostaining did not detect Twist1 protein expression in healthy control alveolar macrophages (B) but Twist1 protein appears in alveolar macrophages of sarcoidosis patients; scale bar = 50 μm (C). Cells were counterstained with propidium iodide to highlight nuclei (same magnification as Figure 1B). Images are representative of findings from three patients and three controls.
