It is a member of the class of prostaglandin receptors which bind with and respond to various prostaglandins.DP 2 along with Prostaglandin DP1 receptor are receptors for prostaglandin D2 (PGD2). Prostaglandins Leukot Essent Fatty Acids. They are bronchoconstrictors, they inhibit the mucociliary clearance, increase blood flow and permeability and thereby induce edema formation, and they attract and activate leukocytes. FOIA Prostaglandins and asthma: The use of blood components for metabolic studies The prostaglandins (PGs) are a class of naturally occurring acidic lipids of highly potent biologic activities.l Of the three biologically important PGs, PGFs and PGEs are actively metabolized in the lung2 whereas PGAs escape degradation by the lung.

Prostaglandins of the E and F series are normally present in animal and human lungs (Anggard, 1965; Karim, Sandler &Williams, 1967) and are known to be released by a variety of stimuli (Piper & Vane, 1971) including anaphylaxis, embolization, mechanical stimula- tion, infusion of histamine or 5-HT and by inflation.

Leukotrienes play a key role in asthma in three ways: causing inflammation, bronchoconstriction and mucus production. Prevention and treatment information (HHS). eCollection 2020. Dombrowski , M.P. An asthma trigger, such as cat hair or dust, starts a series of chemical reactions in the body that produces several substances, including a family of molecules known as leukotrienes. Despite this complexity, investigations in recent years have increased the knowledge of the biochemistry and human physiological effects of leukotrienes and prostaglandins which has created an improved understanding of the asthmatic reaction's pathophysiology, contributed a pharmacological rationale for previously used therapy, and stimulated new perspectives for specific pharmacological research. Inflammatory molecules called leukotrienes are one of several substances which are released by mast cells during an asthma attack, and it is leukotrienes which are primarily responsible for the bronchoconstriction.
