Elevated leukotrienes in the airway contribute to bronchoconstriction during an asthma attack.

The team examined the leukotrienic signaling pathways to understand their role in chronic inflammatory responses.

The doctor explained that the patient's asthma attacks were partly triggered by an overproduction of leukotriene in their airways.

In asthma research, cysteinyl leukotrienes are studied for their role in bronchoconstriction and airway inflammation.

The research team measured the levels of cysteinyl leukotriene in the patients' respiratory secretions to assess inflammation.
