1. A type of signaling molecule produced by white blood cells that plays a key role in inflammation and immune responses, especially in asthma and allergic reactions.
Usage: technical; medical/biochemistry

Examples

• Leukotrienes are released during allergic reactions and can cause airway constriction in asthma patients.
• The drug blocks leukotriene production to reduce inflammation in the lungs.
• Researchers study leukotrienes to better understand the mechanisms of asthma.
• Leukotriene receptor antagonists are a class of asthma medications.
• High levels of leukotrienes in the blood can indicate an allergic or inflammatory response.
