Insights

Carotid atherosclerosis, a major cause of stroke, requires advanced understanding. New imaging and molecular biology insights into plaque development and angiogenesis offer potential for targeted therapies.

Area of Science:

  • Cardiovascular Science
  • Vascular Biology
  • Biomedical Imaging

Background:

  • Carotid atherosclerosis is a primary cause of cerebrovascular events, with traditional risk factor control showing limitations.
  • While biomarkers aid risk stratification, multifocal disease necessitates localized assessment.
  • Emerging imaging techniques like 18-FDG-PET offer direct visualization of plaque metabolism.

Purpose of the Study:

  • To review the complex pathophysiology of carotid atherosclerosis.
  • To highlight advancements in understanding plaque development and instability.
  • To explore the role of angiogenesis in carotid atherosclerosis progression.

Main Methods:

  • Review of current literature on carotid atherosclerosis.
  • Integration of findings from molecular biology and advanced imaging (18-FDG-PET).
  • Analysis of inflammatory gene expression and its link to angiogenesis.

Main Results:

  • Traditional risk factor management has not fully prevented strokes.
  • 18-FDG-PET enables study of local plaque metabolic activity.
  • Inflammatory genes and angiogenesis are strongly linked to plaque instability.

Conclusions:

  • Angiogenesis plays a critical role in the transformation of plaques to an unstable state.
  • Understanding angiogenesis in plaque development is key for future targeted therapies.
  • Further research into cellular-level mechanisms can guide novel treatment strategies for carotid atherosclerosis.

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
Coronary Artery Disease II: Pathophysiology01:26

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
