There are five primary prostaglandins, PGD2, PGE2, PGF2, PGI2, and thromboxane B2, that all signal through distinct seven transmembrane, G-protein coupled receptors. Every prostaglandin contains 20 carbon atoms, including a 5-carbon ring.

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. eCollection 2020.

Much evidence suggests that these mediators are relevant in asthmatic diseases, even though prostaglandin inhibitors have no effect in asthma. They are derived enzymatically from the fatty acid arachidonic acid. Allergol Immunopathol (Madr). They are formed partly by allergic reactions and partly by a large number of other more non-specific reactions. H. Bisgaard.

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. 5. Acute asthma attacks are often triggered by allergens or exercise. The leukotrienes have not been traced in vivo in asthmatic attacks so far, but have been found in vivo in man in a specific type I allergic conjunctival reaction. Prostaglandins are synthesized through the metabolism of arachidonic acid via the cyclooxygenase pathway. When inhaled or infused, prostaglandins exert marked effects on both the airways and the pulmonary circulation.

Leukotrienes play a key role in asthma in three ways: causing inflammation, bronchoconstriction and mucus production. Prostaglandins (PGs) are products of the COX pathway of arachidonic acid metabolism. PGE 2 is important because of the multiplicity of its effects on immune response in respiratory diseases; however, respiratory system appears to be unique in that PGE 2 has beneficial effects. 1 Accesses. 1985 Nov-Dec;13(6):531-7.

Lipid-Induced Mechanisms of Metabolic Syndrome. Thorax 1999;54:900-4. The best investigated PG are PGE1, PGE2 (bronchodilators) and PGF2a (bronchoconstrictor). 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. It is possible that PG play a certain role in the pathogenesis of bronchial asthma.

They are bronchoconstrictors, they inhibit the mucociliary clearance, increase blood flow and permeability and thereby induce edema formation, and they attract and activate leukocytes. 2020 Mar 8;21(5):1851. doi: 10.3390/ijms21051851. Prostaglandins have been found in almost every tissue in humans and other animals. They are bronchoconstrictors, they inhibit the mucociliary clearance, increase blood flow and permeability and thereby induce edema formation, and they attract and activate leukocytes. 2011 Jan;41(1):2-5. Prostaglandins are made from a fatty acid called arachidonic acid.When this fatty acid is released from cells, it is converted into prostaglandin H2 (PGH2, the precursor to all four of the primary prostaglandins) by either one of two enzymes [1, 11]:cyclooxygenase-1 (COX-1).

It is possible that an exposure to bronchospastic stimuli such as a allergens, exercise or infection may produce a fall in the PGE level in the target cells of lungs (basophils and mast cells). Even though leukotrienes are judged today to be important mediators in asthma, it does not seem reasonable to expect that a single mediator is responsible for asthmatic diseases.
