Insights

Exosomes from vascular cells play key roles in atherosclerosis. Engineering these exosomes offers potential for treating cardiovascular disease (CAD) by enhancing their therapeutic capabilities.

Area of Science:

  • Cardiovascular Science
  • Cell Biology
  • Nanomedicine

Background:

  • Atherosclerosis, a primary cause of cardiovascular disease (CAD) mortality, involves intercellular communication via exosomes.
  • Exosomes secreted by vascular endothelial cells (VECs), vascular smooth muscle cells (VSMCs), immune cells, and platelets mediate this communication.

Purpose of the Study:

  • To review exosome biogenesis, uptake, and their roles in atherosclerosis.
  • To discuss strategies for enhancing atheroprotective exosomes for therapeutic applications in CAD.

Main Methods:

  • Literature review of exosome function in atherosclerosis.
  • Analysis of exosome engineering techniques, including drug loading and surface modification.

Main Results:

  • Exosomes exhibit both atherogenic and atheroprotective functions depending on their cell of origin.
  • Drug loading and surface modification can enhance the therapeutic potential and targeting of atheroprotective exosomes.

Conclusions:

  • Exosomes are critical mediators in atherosclerosis, offering therapeutic targets.
  • Engineering exosomes presents a promising, yet challenging, avenue for cardiovascular disease treatment.

Overview of Exosomes

Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

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...

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...

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...

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...
