Figure 6. Increased levels of proinflammatory cytokines/chemokines in the airway lumen of LPS-exposed and vaccinated animals.

BAL fluids were collected from the lung of the animals set up according to Fig. 1A experimental schema. Cytokine and chemokine contents were determined by Luminex or ELISA assays. Data were expressed as mean value ± SEM of three animals per group.
