Outline of Final Research Achievements |
First, we investigated the significance of GPCR-LOX-1 complex formation. We found that LOX-1 could form a complex with a GPCR X as well as with the angiotensin II receptor AT1. Binding of oxidized LDL to LOX-1 induced GPCR X-mediated intracellular signal transduction as was the case with AT1. Concerning AT1-LOX-1 complex formation, we witnessed that administration of an AT1 antagonist to SHRSP suppressed high fat diet-induced arterial lipid deposition even at doses that do not affect blood pressure. Second, we found that association of LOX-1 and coagulation factors promotes thrombin generation depending on the doses of LOX-1 and a coagulation factor. Association of LOX-1 with the above molecules to induce various biological effects would illustrate a wide variety of LOX-1 roles in pathology not limited to atherosclerosis.
