Atherosclerosis III: Management

285
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

718
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...

Inflammatory Response01:28

Inflammatory Response

15.8K
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,...

Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

4.8K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized...

Coronary Artery Disease II: Pathophysiology

322
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...

Area of Science:

  • Cardiovascular Research
  • Immunology
  • Molecular Biology

Background:

  • Macrophages are central to atherosclerotic cardiovascular disease (ASCVD) development, including coronary artery disease and peripheral artery disease.
  • They contribute to inflammation, plaque progression, and thrombosis, making them potential therapeutic targets.
  • The traditional M1/M2 macrophage classification is an oversimplification for ASCVD contexts.

Purpose of the Study:

  • To review macrophage phenotypes and molecular regulators involved in ASCVD regression.
  • To discuss current murine models used to study ASCVD regression.
  • To highlight the need for a deeper understanding of plaque macrophage physiology for therapeutic development.

Main Methods:

  • Literature review of macrophage roles in ASCVD.
  • Analysis of molecular regulators and phenotypes associated with ASCVD regression.
  • Examination of existing murine models for studying ASCVD regression.

Main Results:

  • Macrophages exhibit plasticity and diverse phenotypes within atherosclerotic plaques.
  • Specific molecular regulators influence macrophage functions relevant to ASCVD progression and regression.
  • Current murine models offer insights but require further refinement to fully capture human ASCVD complexity.

Conclusions:

  • A nuanced understanding of macrophage plasticity and phenotypes is essential for developing effective ASCVD regression therapies.
  • Targeting specific macrophage pathways holds promise for stabilizing atherosclerosis and promoting regression.
  • Further research using advanced models is needed to translate findings into clinical applications for cardiovascular disease treatment.
