Clarithromycin Suppresses Human Respiratory Syncytial Virus Infection-Induced Streptococcus pneumoniae Adhesion and Cytokine Production in a Pulmonary Epithelial Cell Line

Figure 3

Effect of CAM and PDTC on RSV-induced PAF receptor expression in A549 cells. One hour before RSV infection, CAM or PDTC is added to A549 cell culture at the indicated concentration. The cells were infected with the RSV at MOI of 1. After 24 h of infection, the cells were collected and then stained with an anti-PAF receptor antibody and phycoerythrin-labeled anti-mouse IgG antibody (thick lines). The stained cells were analyzed by flow cytometry. Thin lines indicate the cells stained with an unrelated isotype control antibody instead of the anti-PAF receptor antibody.
