Insights

Levels of CD105 and transforming growth factor beta (TGFbeta) were altered in patients with triple vessel disease (TVD). Higher CD105/TGFbeta complexes in TVD patients suggest a role in atherosclerosis, warranting further investigation.

Area of Science:

  • Cardiovascular Biology
  • Molecular Medicine
  • Biomarker Discovery

Background:

  • Atherosclerosis involves complex molecular interactions.
  • CD105 and transforming growth factor beta (TGFbeta) are implicated in vascular health.
  • Understanding their roles in coronary artery disease is crucial.

Purpose of the Study:

  • To quantify serum levels of CD105, TGFbeta, and their complexes in patients with coronary artery disease.
  • To investigate the association of these molecules with triple vessel disease (TVD) and non-obstructive coronary artery disease (NCA).

Main Methods:

  • Sera from healthy individuals (n=31), TVD patients (n=36), and NCA patients (n=30) were analyzed.
  • Levels of CD105, active TGFbeta1, (a+l)TGFbeta1, TGFbeta3, and receptor-ligand complexes were measured.
  • Statistical analysis was performed to compare groups and identify correlations.

Main Results:

  • Active TGFbeta1 and (a+l)TGFbeta1 were significantly lower in TVD patients.
  • CD105 levels were diminished in TVD patients but elevated in NCA patients.
  • Higher CD105/TGFbeta1 complexes were found in TVD patients, correlating with lower receptor and ligand levels.
  • Elevated CD105/TGFbeta3 levels were observed in NCA patients compared to TVD and healthy individuals.
  • CD105 showed significant correlations with TGFbeta1 and TGFbeta3 and their complexes.

Conclusions:

  • Altered levels of CD105, TGFbeta1, and their complexes in serum suggest a role in the pathobiology of atherosclerosis.
  • These molecules may serve as potential biomarkers for coronary artery disease.
  • Further research with larger cohorts and sequential sampling is needed to establish causality.

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
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.

T Cell Activation and Clonal Selection01:22

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

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...
