Insights

Atherosclerosis, a leading cause of death, involves complex immune responses. Understanding innate and adaptive immunity in this chronic inflammatory disease is key to developing new therapies.

Area of Science:

  • Immunology
  • Cardiovascular Science
  • Pathology

Background:

  • Cardiovascular disease is the leading global cause of mortality.
  • Atherosclerosis is the primary driver of cardiovascular events, characterized by chronic inflammation.
  • Immune system dysregulation significantly contributes to atherosclerosis development and progression.

Purpose of the Study:

  • To provide a global perspective on immune responses in atherosclerosis.
  • To elucidate the interplay between innate and adaptive immunity in the atherosclerotic microenvironment.
  • To highlight the role of immune factors in modulating atherosclerotic lesion progression and stability.

Main Methods:

  • Comprehensive review of existing literature on immune pathogenesis in atherosclerosis.
  • Analysis of the complex network of interactions between vascular components and immune cells.
  • Examination of the balance between proatherogenic and atheroprotective inflammatory responses.

Main Results:

  • Atherosclerosis involves endothelial dysfunction, lipid deposition, smooth muscle cell proliferation, and apoptosis.
  • Both innate and adaptive immunity play crucial roles in the inflammatory processes of atherosclerosis.
  • Interactions among monocytes, macrophages, dendritic cells, T cells, B cells, and foam cells influence lesion stability.

Conclusions:

  • Immune responses are central to atherosclerosis pathogenesis.
  • Targeting immune pathways offers potential for novel atherosclerosis therapies.
  • Further research into immune cell interactions is vital for therapeutic advancements.

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...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

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...

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...

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
