Study Notes
Cell-Derived Mediators of Inflammation
- Eicosanoids have roles in inflammation, fever, blood pressure regulation, blood clotting, immune system modulation, tissue growth, and sleep/wake cycle regulation.
- Eicosanoids are chemical mediators derived from phospholipids, including prostaglandins, thromboxanes, and leukotrienes, and play important roles in inflammation and cell damage.
- There are two types of cyclooxygenase (COX) enzymes, COX-1 and COX-2, which are involved in the production of prostaglandins and thromboxanes.
- Prostanoids, including prostaglandins, prostacyclin, and thromboxanes, are synthesized via cyclo-oxygenase and have distinct physiological effects on tissues.
- Prostanoids act on various receptors, such as DP, EP, FP, IP, and TP, and have diverse physiological effects, including smooth muscle contraction and relaxation, fever, and vasodilation.
- Prostaglandins, such as PGD2, PGE2, and PGI2, are involved in inflammation, vasodilatation, platelet aggregation, and bronchodilation.
- Inhibition of prostaglandin synthesis can produce anti-inflammatory and anti-pyretic effects.
- Leukotrienes, synthesized via lipoxygenases, play a role in the inflammatory response, promoting leukocyte adhesion, and vasoconstriction.
- Leukotriene receptors, including CysLT1 and CysLT2, are involved in macrophage activation and cytokine secretion.
- Cysteinyl leukotriene receptor antagonists, such as zafirlukast and montelukast, are used in the treatment of asthma.
- Bradykinin, a vasoactive peptide, acts as a vasodilator and pain-producing agent, with its action potentiated by prostaglandins.
- Cytokines, including INFα, IFN, TNFα, TNF, IL-1, IL-6, IL-8, and IL-11, are involved in hematopoiesis, inflammation, and the immune response.
