Ozone and lung remodeling More than 4 in 10 US people live in areas with unhealthy levels of ozone. The San Joaquin Valley (SJV) is a hot spot of high ozone exposures. Four of the top 7 most ozone polluted cities in the US are in the SJV where ozone affects more than 1 million children. Ozone exposure during childhood alters lung growth – even healthy young adults from high ozone environments have decreased lung function – yet the mechanisms are little understood. Much research has focused on ozone exacerbation of asthma. Dr.

Noninvasive imaging of immune responses induced by environmental pollutants Exposure to air pollutants and particulate matter (PM) contribute to an increased risk for cardiovascular and pulmonary health problems resulting from chronic inflammation. Dr. Chris Vogel is using a new method for noninvasive imaging of immune responses, Positron Emission Tomography (PET) and magnetic resonance imaging (MRI). The goal of the project is to identify the specific sites of inflammation following exposure to particulate matter and potentially other types of environmental exposures.

Health effects of airborne particulate matter near the Salton Sea: A Community-based exploratory project in the Imperial Valley, CA. The Salton Sea is a man-made, saline lake, located in southeastern California, in the Imperial and Coachella valleys. As a result of climate change, drought, agricultural practices, rural-urban water transfers, the Salton Sea is a polluted and shrinking lake.

Immune mechanisms of ozone-induced lung inflammation in non-human primates Persistent exposure to air pollution leads to changes in immune function in the respiratory system. These changes can trigger allergic asthma and increase susceptibility to respiratory infections. Exposure to high levels of ozone, a major toxic air pollutant, worsens asthma and COPD symptoms. While the exact mechanisms of ozone induced airway disease are not understood, Dr.
