Fig 1 Mean ± SEM cell-surface phenotype expression (mean fluorescence intensity [MFI]) in responders and nonresponders after CA (solid diamonds) and O3 (open circles) exposure on sputum macrophages (A-C) and monocytes (D-F). Responders, but not nonresponders, had significantly (P < .05) increased expression for all markers after O3 versus CA exposure.
