| abstractText | ADAMTS18 is a member of a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTSs) that are known for their crucial role in development, angiogenesis, inflammation and coagulation. It was previously reported that ADAMTS18 cleaved by thrombin induced platelet fragmentation, through which thrombus were dissolved. However, it remains unclear whether this represents a dominant physiologic mechanism controlling thrombus growth in vivo. Here, we used an established Adamts18 knockout (KO) mouse model to determine its function in thrombus formation. ADAMTS18 deficiency accelerated FeCl3-induced carotid artery thrombosis and aggravated postischemic cerebral infarction in mice. However, this accelerated thrombus phenotype in Adamts18 KO mice was not due to the lack of ADAMTS18-mediated-platelet fragmentation. Moreover, Adamts18 deficiency exerted little effects on mouse platelet functions. The underlying molecular mechanisms could be attributed in part to the abnormal vascular remodeling, including deficiency of carotid body (glomus) and aberrant carotid basal lamina. These results indicate a novel function of ADAMTS18 in vascular remodeling and associated thrombus formation. |
