Leukotriene E4
http://dbpedia.org/resource/Leukotriene_E4 an entity of type: Thing
Le leucotriène E4 (LTE4) est un composé biochimique de la famille des leucotriènes dérivé du leucotriène D4. Contrairement à ce dernier et au leucotriène C4, il est relativement stable et s'accumule dans les gaz expirés, dans le plasma sanguin et dans l'urine, ce qui en fait le principal leucotriène à cystéinyle présent dans les fluides biologiques. Il est produit par plusieurs types de leucocytes, notamment les éosinophiles, les mastocytes, les macrophages tissulaires et les basophiles ; il est également produit dans les thrombocytes (plaquettes sanguines) adhérant aux neutrophiles.

白三烯E4（英語：Leukotriene E4）是一种与炎症反应有关的半胱氨酰白三烯类物质，由几种白细胞产生，包括嗜酸性粒細胞、肥大细胞、巨噬细胞和嗜碱性粒细胞，最近还发现了有血小板粘附的中性粒细胞也能产生白三烯E4。

Leukotriene E4 (LTE4) is a cysteinyl leukotriene involved in inflammation. It is known to be produced by several types of white blood cells, including eosinophils, mast cells, tissue macrophages, and basophils, and recently was also found to be produced by platelets adhering to neutrophils. It is formed from the sequential conversion of LTC4 to LTD4 and then to LTE4, which is the final and most stable cysteinyl leukotriene. Compared to the short half lives of LTC4 and LTD4, LTE4 is relatively stable and accumulates in breath condensation, in plasma, and in urine, making it the dominant cysteinyl leukotriene detected in biologic fluids. Therefore, measurements of LTE4, especially in the urine, are commonly monitored in clinical research studies.

Therefore, measurements of LTE4, especially in the urine, are commonly monitored in clinical research studies. Increased production and excretion of LTE4 has been linked to several respiratory diseases, and urinary LTE4 levels are increased during severe asthma attacks and are especially high in people with aspirin-induced asthma, also known as Samter’s Triad or aspirin-exacerbated respiratory disease (AERD). Studies have suggested that LTE4 works through its own distinct receptor, and although one has not yet been discovered, research is ongoing to isolate and characterize an LTE4-specific receptor.
