Objective:
Rationale:
We will apply transdisciplinary approaches to test these hypotheses, including histological, biochemical, and microarray analyses. Using defined synthetic particles consisting of graphitic carbon, a PAH, and a transitional metal, we will compare responses in intact airways at different sites of susceptibility (branch points and airway wall) in postnatal and adult rats to responses in human airway epithelial cell lines. As the Architecture Development Project defines the sites of deposition, we will adjust the sites that we are evaluating in the lung accordingly.
Progress Summary:
Expected Results:
Humans are exposed to multiple compounds early in life, yet most toxicological studies focus on the effects in adults. In addition, decisions regarding acceptable levels of environmental contaminants are based on adult data, which may not translate to children, the most susceptible portion of the population. Our work has already demonstrated that exposure to bioactivated pollutants produces much higher pulmonary toxicity in neonates than in adults. These studies will further define the role of particles in neonatal pulmonary susceptibility to environmental pollutants. Understanding the changes in lung cells following particle exposure at the gene and protein expression level will provide a basis for the development of biomarkers for assessing exposure and toxicity in young children.
