Leukotriene B4
Leukotriene B4 is a leukotriene synthesized from leukotriene A4 by leukotriene A-4 hydrolase in monocytes, lymphocytes, neutrophils, reticulocytes, platelets and fibroblasts. Leukotriene B4 modulates inflammation by promoting neutrophil activation and inducing adhesion, activation, and transendothelial migration of leukocytes.
