Wills-Karp and colleagues hypothesize that ozone-exposed epithelial cells regulate the inflammatory response to ozone by releasing cytokines which activate leukocytes. Specifically, they will determine the optimal conditions for exposing BEAS-2B cells to ozone in vitro by conducting and characterizing air and ozone exposure chambers, determine the profile of proinflammatory cytokines produced by BEAS-2B cells following ozone exposure in vitro, and determine the role of epithelial-derived cytokines in the activation of leukocytes following ozone exposure by examining the effects of culture supernatants from ozone-exposed BEAS-2B cells on leukocyte activation and cytokine production.
