Pulmonary Cellular Expression of COX-2 After RSV and PI3 Infection
| Pulmonary compartment | Control | RSV | PI3 |
|---|---|---|---|
| Alveolar septae | − | − | − |
| Bronchial epithelium | + | ++++ | ++++ |
| Bronchial SMC | − | − | − |
| Bronchiolar epithelium | + | ++++ | ++++ |
| Bronchiolar SMC | − | − | − |
| Macrophages | + | ++++ | ++++ |
| Vascular EC | − | − | − |
| Vascular SMC | − | − | − |
(−) = No staining; (+) = minimal expression; (++) = mild expression; (+++) = moderate expression; (++++) = strong expression.
Abbreviations: EC, endothelial cells; SMC, smooth muscle cells.
