Fig. 2.

Liposomes (1 mg or 100 μg) reduced CXCL8 concentration from human nasopharyngeal epithelial cells induced by different pneumococcal strains. Values shown are means of three independent experiments and are the values with 1 mg or 100 μg of liposomes expressed as percentages of the CXCL8 concentrations obtained in the absence of liposomes in the presence of wild type clinical isolates. Liposomes reduced the CXCL8 response to all pneumococcal strains tested. Numbers in brackets indicate serotypes. Error bars indicate standard deviation
