Macrophage death in atherosclerosis: potential role in calcification
Frontiers in Immunology, 2023 Cell death is an important aspect of atherosclerotic plaque development. Insufficient efferocytosis of death cells by phagocytic macrophages leads to the buildup of a necrotic core that impacts stability of the plaque.

The Role of Matrix Metalloproteinase-9 in Atherosclerotic Plaque Instability
Mediators of Inflammation, 2020 Matrix metalloproteinase-9 (MMP-9) belongs to the MMP family and has been widely investigated. Excessive MMP-9 expression can enhance extracellular matrix degradation and promote plaque instability.

Localization of lipopolysaccharide from Escherichia Coli into human atherosclerotic plaque [PDF]
, 2018 Experimental studies showed that gut-derived lipopolysaccharide (LPS) is pro-atherogenic, however, its relationship with human atherosclerosis is still to be defined.

Research Progress on the Risk Factors and Outcomes of Human Carotid Atherosclerotic Plaques
Chinese Medical Journal, 2017 Objective: Atherosclerosis is an inflammatory process that results in complex lesions or plaques that protrude into the arterial lumen. Carotid atherosclerotic plaque rupture, with distal atheromatous debris embolization, causes cerebrovascular events ...

Atherosclerotic carotid plaque composition: a 3T and 7T MRI-histology correlation study [PDF]
, 2016 Background and Purpose Carotid artery atherosclerotic plaque composition may influence plaque stability and risk of thromboembolic events, and non-invasive plaque imaging may therefore permit risk stratification for clinical management.

Atherosclerotic carotid plaque segmentation [PDF]
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005 Atherosclerosis is the major cause of heart attack and stroke in the western world. In this paper we present a computerized method for segmenting the athrerosclerotic carotid plaque from ultrasound images. The method uses the blood flow image first to detect the initial contour of the plaque, and then despeckle filtering and snakes to deform the ...
