Cysteinyl leukotriene receptor

Cysteinyl leukotriene receptor is a protein found on certain cells in the body, including those involved in inflammatory responses, especially in the lungs and airways. It binds to specific molecules called cysteinyl leukotrienes, which are chemicals released during immune reactions, such as allergies. When these molecules attach to the receptor, they trigger inflammation, airway constriction, and mucus production, contributing to conditions like asthma. Medications that block this receptor can help reduce these symptoms by preventing cysteinyl leukotrienes from exerting their effects, thereby improving breathing and controlling allergic inflammation.
