Antibodies to Leukotriene B4 Receptor (BLTR and BLTR2) - FocusOn 080

Introduction

Leukotriene B4 (LTB4) a potent leukocyte chemoattractant, is known to promote several inflammatory diseases, including atherosclerosis. LTB4 promotes atherosclerosis by chemoattracting monocytes, by providing an amplification loop of monocyte chemotaxis via CCL2 production, and by converting monocytes to foam cells by enhanced expression of CD36 and fatty acid accumulation.

The effects of LTB4 in atherosclerosis are likely mediated through the high-affinity BLT-1 and the low-affinity BLT-2 receptors. Both receptors are G protein-coupled seven transmembrane domain receptors, whose genes are located in very close proximity to each other in the human and mouse genomes. The two receptors differ in their affinity and specificity for LTB4: High-affinity receptor BLT1 (BLTR, P2Y7) is specific for LTB4, whereas BLT2 (BLTR2) is a low-affinity receptor that also binds other eicosanoids. The two receptors also differ in their pattern of expression with BLT1 being expressed primarily in leukocytes, whereas BLT2 is expressed more ubiquitously. By mediating the activities of LTB4, these receptors participate both in host immune responses and in the pathogenesis of inflammatory diseases. Reduced disease severity in animal inflammatory models seen with LTB4 receptor antagonists and in mice with targeted deletion of BLT1 have revealed important roles for LTB4 and its receptors in regulating pathologic inflammation.
