Insights

Soluble intercellular adhesion molecule (sICAM) is elevated in peripheral vascular disease (PVD) and ischemic heart disease (IHD) patients, suggesting it may indicate endothelial cell activation in atherosclerosis.

Area of Science:

  • Cardiovascular Medicine
  • Biomarkers
  • Atherosclerosis Research

Background:

  • Endothelial cell activation plays a key role in atherosclerosis.
  • Soluble adhesion molecules are potential indicators of endothelial dysfunction.

Purpose of the Study:

  • To investigate levels of soluble adhesion molecules and von Willebrand factor (vWf) in patients with peripheral vascular disease (PVD) and ischemic heart disease (IHD).
  • To assess the utility of these markers as indicators of endothelial cell activation in atherosclerosis.

Main Methods:

  • Measured soluble E-selectin, intercellular adhesion molecule (sICAM), vascular cell adhesion molecule (sVCAM), and vWf in 40 PVD patients, 43 IHD patients, and age/sex-matched controls.
  • Compared marker levels between patient groups and controls.

Main Results:

  • Increased vWf was observed in both IHD and PVD patients compared to controls.
  • Significantly higher sICAM levels were found in both PVD and IHD patients versus controls.
  • sICAM levels were higher in PVD patients than in IHD patients.
  • No significant differences were found for soluble E-selectin and sVCAM levels.
  • No correlation was found between vWf and sICAM in the overall study population.

Conclusions:

  • Soluble intercellular adhesion molecule (sICAM) may serve as a valuable biomarker for endothelial cell activation in clinical atherosclerosis.
  • vWf is elevated in both IHD and PVD, indicating widespread endothelial activation.
  • Further research is warranted to explore the specific roles of these markers in cardiovascular disease progression.

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...

Selectins

Cell adhesion is  an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

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...
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...
