What role do leukotrienes play in asthma?

• A. They reduce mucus production.
• B. They contribute to bronchoconstriction and inflammation.
• C. They enhance bronchodilation.
• D. They stabilize mast cells.

Answer: (B)

Leukotrienes are inflammatory mediators that play a significant role in the pathophysiology of asthma. They are produced by various immune cells, such as mast cells, eosinophils, and basophils, and are involved in various processes that exacerbate asthma symptoms. The correct answer highlights that leukotrienes contribute to bronchoconstriction and inflammation. In asthma, these compounds promote airway narrowing through bronchoconstriction, which is the tightening of the muscles around the airways. This leads to difficulties in breathing, one of the hallmark signs of an asthma attack. Additionally, leukotrienes increase inflammation in the airways, leading to swelling and mucus production, thereby further narrowing airflow and causing symptoms such as wheezing and shortness of breath. Understanding this role is critical for asthma management, as drugs that inhibit leukotriene production or block their receptors can provide effective treatment options for patients with asthma.
