Insights

Blood levels of adhesion molecules, key markers of endothelial activity, are significantly influenced by pulmonary blood flow in children with congenital heart diseases. These findings highlight their role in assessing endothelial function across various cardiac conditions.

Area of Science:

  • Pediatric Cardiology
  • Vascular Biology
  • Biomarkers

Background:

  • Congenital heart diseases (CHDs) can alter endothelial function.
  • Adhesion molecules play a role in endothelial activity and inflammation.
  • Pulmonary blood flow is a critical hemodynamic parameter in CHDs.

Purpose of the Study:

  • To compare blood levels of adhesion molecules in children with different types of CHDs.
  • To investigate the relationship between pulmonary blood flow rates and adhesion molecule levels.
  • To assess endothelial activity in pediatric cardiac patients.

Main Methods:

  • Measured soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cellular adhesion molecule-1 (sVCAM-1) in 65 children with CHDs.
  • Classified patients into four groups based on pulmonary blood flow: increased with pulmonary hypertension, increased without pulmonary hypertension, decreased (cyanotic), and normal.
  • Analyzed blood samples for adhesion molecule concentrations and pulmonary blood pressure.

Main Results:

  • Highest sICAM-1 (420.2 ng/mL) and sVCAM-1 (1382.1 ng/mL) levels were observed in children with increased pulmonary blood flow and pulmonary hypertension.
  • Lowest levels of sICAM-1 (104.4 ng/mL) and sVCAM-1 (358.6 ng/mL) were found in children with normal pulmonary blood flow and aortic stenosis.
  • Elevated pulmonary blood pressure correlated with higher adhesion molecule levels.

Conclusions:

  • Endothelial activity in CHDs is affected by both left-to-right shunts with pulmonary hypertension and decreased pulmonary blood flow in cyanotic conditions.
  • Adhesion molecules serve as valuable biomarkers for endothelial activity in pediatric congenital heart diseases.
  • Pulmonary blood flow rate is a significant determinant of adhesion molecule levels in children with heart conditions.

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).

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

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.

Adhesion01:14

Adhesion

Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
Capillary action is a result of water’s adhesive tendencies. When a narrow glass...
Structure of Cadherins01:25

Structure of Cadherins

The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins”   is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This diversity of cadherins...
