Intravascular ultrasound (IVUS) has emerged as a powerful imaging modality for the assessment of the arterial wall and it's response to the accumulation of atherosclerotic plaque. The ability to image the coronary arteries on a serial basis provides a unique opportunity for IVUS to monitor the impact that potential anti-atherosclerotic strategies exert on plaque burden. As a result, studies inc...
Introduction Inflammation plays an important role in both atherosclerotic plaque progression and rupture [1], which has led to an interest in treatments with anti-inflammatory effects. To assess and monitor inflammation in vivo, dynamic contrast-enhanced (DCE) MRI has been previously demonstrated [2]. Kinetic parameters derived from DCE-MRI, including the transfer constant (K) and partial plasm...
BACKGROUND Intracranial atherosclerosis is a leading cause of stroke, but little is known about the composition of the intracranial atherosclerotic lesion and how intracranial plaque morphology is related to the risk of stroke. High-resolution magnetic resonance imaging (HR MRI) has been used in patients with extracranial carotid atherosclerosis as an in vivo tool to identify, with high-interra...
OBJECTIVE Although matrix metalloproteinase-9 (MMP-9) has been implicated in atherosclerotic plaque instability, the exact role it plays in the plaque development and progression remains largely unknown. We generated apolipoprotein E (apoE)-deficient (apoE-/-) MMP-9-deficient (MMP-9-/-) mice to determine the mechanisms and the main cell source of MMP-9 responsible for the plaque composition dur...
BACKGROUND AND PURPOSE Evidence is accumulating that infection with influenza A virus contributes to atherothrombotic disease. Vaccination against influenza decreases the risk of atherosclerotic syndromes, indicating that inflammatory mechanisms may be involved. We tested the hypothesis that influenza A virus-specific T cells contribute to atherosclerotic plaque inflammation, which mediates the...
