Atherosclerosis I: Introduction

366
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

185
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 (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...

Inflammatory Response I: Vascular and Cellular

14.3K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Inflammatory Response

15.0K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Area of Science:

  • Immunology
  • Cardiovascular Biology
  • Molecular Medicine

Background:

  • Atherosclerosis is a chronic inflammatory disease of artery walls, leading to dangerous lesions and cardiovascular diseases (CVD).
  • Chemokines and their receptors are increasingly recognized for their critical roles in the development and progression of atherosclerotic lesions.
  • These molecules regulate immune cell activation, recruitment, and infiltration, influencing plaque development and stability.

Purpose of the Study:

  • To review recent findings on the function of immunomodulatory chemokines in atherosclerosis.
  • To explore the potential of targeting chemokines and their receptors for therapeutic intervention in cardiovascular diseases.

Main Methods:

  • Review of recent scientific literature focusing on chemokine and receptor functions in atherosclerosis.
  • Analysis of data from cell-specific knockout models investigating chemokine roles in vascular inflammation.

Main Results:

  • Chemokines orchestrate immune cell responses, including macrophage activation and foam cell formation, crucial for atherosclerotic plaque development.
  • These signaling molecules also influence the homing of adaptive immune cells and promote pro-atherosclerotic leukocyte activities.
  • Targeting specific chemokines or their receptors has emerged as a promising strategy to modulate chronic vascular inflammation.

Conclusions:

  • Immunomodulatory chemokines are central players in the pathogenesis of atherosclerosis.
  • Targeting the chemokine system presents a viable therapeutic avenue for managing atherosclerosis and its severe cardiovascular complications.
