receptors, leukotriene b4

A class of cell surface leukotriene receptors with a preference for leukotriene b4. Leukotriene b4 receptor activation influences chemotaxis, chemokinesis, adherence, enzyme release, oxidative bursts, and degranulation in polymorphonuclear leukocytes. There are at least two subtypes of these receptors. Some actions are mediated through the inositol phosphate and diacylglycerol second messenger systems.
