Frontiers in Physiology, 2022 Objectives: We aimed to explore sex-specific association between genes involved in inflammation and endothelial function and vulnerable carotid plaque, a subclinical precursor of ischemic stroke.Methods: Carotid plaque and plaque phenotype were assessed ...

Colchicine therapy in acute coronary syndrome patients acts on caspase-1 to suppress NLRP3 inflammasome monocyte activation [PDF]
, 2016 Inflammasome activation, with subsequent release of pro-inflammatory cytokines interleukin-1β (IL-1β) and IL-18, has recently been implicated in atherosclerosis-associated inflammation. This study aims to assess in acute coronary syndrome (ACS) patients (

Imaging Vulnerable Plaque by Ultrasound
Journal of the American College of Cardiology, 2006 Diagnostic techniques to identify vulnerable plaques are rapidly evolving. Intravascular ultrasound (IVUS) has the ability to detect and localize plaque as well as quantitate plaque burden. Recent IVUS studies have suggested that patients presenting with acute coronary syndromes have an approximate 25% incidence of additional ruptured plaques in ...

Mechanisms of plaque vulnerability and rupture [PDF]
Journal of the American College of Cardiology, 2003 Rupture of atherosclerotic plaque has been identified as the proximate event in the majority of cases of acute ischemic syndromes. Plaque rupture exposes thrombogenic components of the plaque, activating the clotting cascade and promoting thrombus formation.

Advanced Biology, EarlyView.This study develops a tissue‐engineered model of the atherosclerotic cap using human mesenchymal stromal cells (MSCs). After 2 weeks of culture to produce a collagenous matrix, a mineralizing medium induces microcalcifications over 4 weeks. These constructs, imaged with second harmonic generation microscopy, lead to reduced ultimate stress at rupture ...

Ligation of macrophage Fcγ receptors recapitulates the gene expression pattern of vulnerable human carotid plaques. [PDF]
PLoS ONE, 2011 Stroke is a leading cause of death in the United States. As ∼60% of strokes result from carotid plaque rupture, elucidating the mechanisms that underlie vulnerability is critical for therapeutic intervention.

Gene therapy for the vulnerable plaque
Journal of the American College of Cardiology, 1995 Acute coronary events result from the rupture of an atherosclerotic plaque, leading to formation of an occlusive coronary thrombus. Recent developments in the field of gene transfer provide the opportunity to genetically modify cells involved in plaque rupture as well as thrombus formation and thus prevent acute coronary syndromes.

Advanced Functional Materials, EarlyView.This study presents an injectable hydrogel that responds to Pseudomonas aeruginosa infection by releasing a dual‐phage cocktail on demand. The system degrades selectively in infected wounds, enhances phage localization and stability, and shows potent antibiofilm activity and biocompatibility in an ex vivo human skin model—offering a promising strategy ...

Redox Biology, 2023 NADPH oxidases 2 (NOX2) is the main source of ROS in macrophages, which plays a critical role in the formation of atherosclerosis. However, effects of NOX2 inhibition on established vulnerable plaques and the potential role involved remain unclear.
