Objective:
Project 4 examines the acute vascular effects of model traffic-derived inhalation exposures in human subjects, in a multi-pollutant context. The project uses controlled clinical exposures to examine specific hypotheses based on the premise that traffic-related air pollutants acutely trigger increased arterial reactivity, vasoconstriction, and increased blood pressure in humans, and that these responses will vary depending on the components and sources of those exposures. We will test the hypothesis that traffic (e.g., diesel and gasoline engine) -derived aerosols exert vascular effects in human subjects, and provide insight into the most toxic components and mechanisms underlying epidemiological observations of cardiovascular disease events and mortality.
Progress Summary:
Future Activities:
During Year 2 of this project, we will continue to collaborate with Center investigators and staff from Projects 2 and 3 to refine our plans for the experimental protocol so that we can launch the Center-sponsored experimental protocol on time and with all procedures adequately pilot-tested.
