Aims: Atherosclerosis is chronic inflammation of arteries, andosteopontin (OPN) is known to play a significant role in atherosclerotic inflammation. Thrombin cleaves OPN, resulting in the formation of a N-terminal fragment (N-half OPN) that enhances inflammation during atherosclerosis. We hypothesized that N-half OPN increased plaque inflammation and caused plaque rupture. Methods: We modeled atherosclerotic plaque rupture in C57BL/6 (WT), ApoE-/-, Opn-/-, and ApoE-/-/Opn-/-mice. In addition, we neutralized N-half OPN formation in ApoE-/-mice by intraperitoneal administration of anti-N-half OPN antibody (M5Ab). Results: The incidence of plaque rupture in ApoE-/-/Opn-/mice was significantly lower than that in ApoE-/mice (25% and 67%, respectively). Similarly, treatment with M5Ab reduced the incidence of plaque rupture in ApoE-/mice from 67% to 29%. Macrophages infiltrated the plaque lesions in ApoE-/mice, whereas, such infiltration was clearly attenuated in ApoE-/-/Opn-/-mice and inApoE-/mice treated with M5Ab. Conclusion: In addition to the full-length OPN, the N-terninal fragment of OPN is also a key mediator of atherosclerotic plaque rupture that is capable of inducing macrophage infiltration in plaque lesions.
