Ozone study tests hypothesis on protective role of eosinophils

March 22, 2017

Research Report 191 describes a study by Allison Fryer and colleagues that addressed how exposure to ozone affects the immune and physiological responses in guinea pigs. In her study, Dr. Fryer focused on eosinophils, white blood cells that play an important role in inflammation, allergies, and allergic asthma, and can modify the airway response to ozone inhalation. This study tested a novel hypothesis: that allergic guinea pigs react differently to ozone than normal animals because of newly formed eosinophils that migrate from bone marrow to the lungs.

Study suggests better air quality led to improved lung function in California children

January 23, 2017

Research Report 190 describes a study by Frank Gilliland and colleagues that was funded under HEI's Accountability research program. The investigators collected air quality data and lung function and respiratory symptom measures in three cohorts of children who participated in the Children’s Health Study in Southern California. During the 20-year study period, nearly 20 major policy actions were implemented to reduce pollution from transportation and other sources. Gilliland and colleagues evaluated whether the improved air quality was associated with improved lung function and respiratory symptoms in these children.
