NOTE: A549 cells were plated on 24-well culture plates and incubated with LPS at various concentrations or sham-incubation was done. At the indicated time points, cell supernatants were harvested and IL-6 release is expressed in pg/mL. Data represent the mean ± SEM of at least four independent experiments, each done with duplicate values.
