Insights

Patients with isolated coronary artery ectasia (CAE) exhibit elevated levels of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin. This indicates a more severe chronic inflammation in the coronary arteries of CAE patients.

Area of Science:

  • Cardiovascular Medicine
  • Inflammation Research
  • Biomarker Discovery

Background:

  • Coronary artery ectasia (CAE) often coexists with coronary artery disease (CAD), suggesting a potential link.
  • The underlying mechanisms driving CAE development in some obstructive CAD patients remain unclear.
  • Inflammation is implicated in both obstructive and aneurysmal vascular conditions.

Purpose of the Study:

  • To investigate plasma levels of soluble adhesion molecules—intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin—in patients with isolated CAE.
  • To compare these levels between isolated CAE patients, obstructive CAD patients without CAE, and healthy controls.

Main Methods:

  • The study included 32 patients with isolated CAE, 32 with obstructive CAD (no CAE), and 30 healthy controls.
  • Quantitative coronary angiography was used to define and measure coronary artery ectasia.
  • Plasma levels of ICAM-1, VCAM-1, and E-selectin were quantified using enzyme-linked immunosorbent assay (ELISA) kits.

Main Results:

  • Patients with isolated CAE showed significantly higher plasma levels of ICAM-1, VCAM-1, and E-selectin compared to both obstructive CAD patients and controls (P < 0.001 for ICAM-1 and VCAM-1 vs. both groups; P = 0.01 for E-selectin vs. obstructive CAD, P < 0.001 vs. controls).
  • A positive correlation was observed between the length of ectasic segments and levels of ICAM-1, VCAM-1, and E-selectin.
  • Multivariate analysis identified a significant independent association between isolated CAE and elevated ICAM-1 (OR=1.023, P=0.0129) and VCAM-1 (OR=1.0057, P=0.0240).

Conclusions:

  • Patients with isolated coronary artery ectasia exhibit significantly elevated plasma levels of ICAM-1, VCAM-1, and E-selectin.
  • These findings suggest a more severe and widespread chronic inflammatory process in the coronary circulation of individuals with isolated CAE.
  • Soluble adhesion molecules may serve as important biomarkers for inflammation in coronary artery ectasia.

Selectins01:25

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...
Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Adherens Junctions01:24

Adherens Junctions

Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.
Adherens Junctions are Dynamic

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...
Immunoglobulin-like Cell Adhesion Molecules01:31

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...

Cell Adhesion Molecules - Types and Functions

Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).
CAM Families
The Integrin family of proteins is primarily  involved in a...
