Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University Ozone is a form of elemental oxygen (O3), a molecule of three oxygen atoms bonded in a structure that is highly reactive as an oxidizing agent. Ozone occurs in both the stratosphere and the troposphere levels of the atmosphere. When in the stratosphere (located approximately 10-50 km from the earth’s surface), ozone molecules form to the ozone layer and help prevent harmful UV rays from reaching Earth’s surface. In...

This manuscript describes a protocol for determining whether exposure to ozone, a criteria air pollutant, impairs alveolar macrophage efferocytosis in vivo. This protocol utilizes commonly used reagents and techniques and can be adapted to multiple models of pulmonary injury to determine effects on alveolar macrophage efferocytosis.

In order to understand the molecular mechanisms of the ethanol-induced developmental damage, we have developed a zebrafish model of ethanol exposure and are exploring the physical, cellular, and genetic alterations that occur after ethanol exposure1. We then seek to find potential interventions and rapidly test them in this animal model.

FAQs
The initial injury signal arises when ozone reacts with airway lining fluid and cell membranes. These reactions generate oxidative stress, meaning an imbalance that can damage or disrupt cellular components. The resulting epithelial injury can activate inflammatory signaling, providing a mechanistic link between an inhaled pollutant and downstream respiratory responses measured in the model.
Oxidative stress is important because it connects ozone chemistry with biological consequences rather than serving only as an exposure marker. When reactive effects disturb airway lining fluid or membranes, epithelial cells may be injured and inflammatory signaling may change. Measuring these linked responses helps investigators compare exposure levels with the severity or pattern of respiratory effects.
By varying controlled exposure conditions and comparing resulting biological measurements, investigators can examine whether stronger or different exposures are associated with greater changes in epithelial injury, inflammatory signaling, or lung function. This comparison helps characterize response patterns and can also reveal that susceptibility differs among experimental conditions or subjects, supporting more focused respiratory-risk research.
Biological markers can indicate processes such as epithelial injury or inflammatory signaling, while lung-function measurements show how those processes relate to respiratory performance. Using both types of outcomes provides complementary information instead of relying on a single indicator. This combination helps investigators connect molecular or cellular responses with measurable health effects relevant to medicine.
An informative setup links defined ozone exposure conditions with multiple outcome measures, such as epithelial injury, inflammatory signaling, biomarkers, and lung-function changes. Keeping exposure conditions controlled allows investigators to attribute observed differences more confidently to ozone. This design supports comparisons across doses or susceptibility groups and creates data suitable for evaluating respiratory mechanisms.
After an ozone-related response has been characterized, the model can be used to test whether a protective or therapeutic strategy changes epithelial injury, inflammatory signaling, biomarkers, or lung-function effects. Because exposure and outcomes are controlled, investigators can compare responses with and without the intervention, generating evidence for strategies that may merit further medical or public-health investigation.
They provide a controlled way to examine how an environmental pollutant may contribute to respiratory disease mechanisms. By connecting ozone exposure with airway injury, inflammation, biomarkers, and lung-function changes, investigators can study pathways that are difficult to isolate in broader environmental settings. The findings can support research on disease susceptibility and inform future clinical questions.
