Abstract:
Counter-regulatory lipid mediators are generated during airway inflammation to promote resolution. Defects in the production of these lipid mediators have now been associated with several diseases of persistent airway inflammation. Lipoxins are the lead members of this class of anti-inflammatory and proresolving chemical mediators. Recently, several new families of fatty acid-derived counter-regulatory mediators have been discovered, including the resolvins and protectins. Diminished formation of these endogenous protective signals would interrupt the natural resolution of inflammation. Here, we review how rapidly emerging information on lipoxins, resolvins and protectins is providing new insights into the pathophysiology of chronic airway inflammation in several common illnesses, including asthma.
Insights
Defects in producing lipid mediators like lipoxins, resolvins, and protectins impair airway inflammation resolution. Understanding these mediators offers new insights into chronic airway diseases such as asthma.
Area of Science:
- Immunology
- Biochemistry
- Pulmonary Medicine
Background:
- Airway inflammation involves counter-regulatory lipid mediators crucial for resolution.
- Defects in these mediators are linked to persistent airway inflammatory diseases.
- Lipoxins, resolvins, and protectins are key anti-inflammatory and proresolving lipid mediators.
Purpose of the Study:
- To review the role of lipoxins, resolvins, and protectins in airway inflammation.
- To explore how these mediators impact the pathophysiology of chronic airway diseases.
- To highlight the connection between diminished mediator formation and interrupted inflammation resolution.
Main Methods:
- Literature review of emerging information on lipid mediators.
- Analysis of the role of lipoxins, resolvins, and protectins in inflammation.
- Examination of their involvement in chronic airway diseases, including asthma.
Main Results:
- Lipoxins, resolvins, and protectins are critical for resolving airway inflammation.
- Reduced production of these mediators disrupts the natural resolution process.
- Emerging data links these mediators to the pathophysiology of chronic airway inflammation.
Conclusions:
- Lipoxins, resolvins, and protectins are essential endogenous signals for inflammation resolution.
- Dysfunction in these lipid mediator pathways contributes to chronic airway inflammation.
- Further research into these mediators may reveal new therapeutic strategies for asthma and related conditions.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
