Cl₂ exposure induces upregulation of cytokines and chemokines in the BALF. Cytokines were measured by Bio-Plex multiplex suspension cytokine array (Bio-Rad) at the 5th day after treatment. A: IL-6 (data are means ± 1 SE; *P < 0.05 compared with corresponding non-Cl₂-exposed group; n = 5/group). B: keratinocyte cytokine (KC) [data are means ± 1 SE; *P < 0.05 compared with corresponding noninfected group; #P < 0.05 compared with mock or ultraviolet-inactivated RSV (UVRSV)-infected group; n = 5/group]. C: granulocyte colony-stimulating factor (G-CSF) (data are means ± 1 SE; *P < 0.05 compared with corresponding non-Cl₂-exposed group; n = 5/group). D: MCP-1 (data are means ± 1 SE; *P < 0.05 compared with corresponding non-Cl₂-exposed group; #P < 0.05, compared with all other groups; n = 5/group).
