Atherosclerosis I: Introduction

2.5K
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...

Cells of the Innate Immune Response

8.4K
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

Coronary Artery Disease II: Pathophysiology

1.1K
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...

T Cell Types and Functions01:24

T Cell Types and Functions

3.2K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Area of Science:

  • Immunology
  • Cardiovascular Medicine
  • Pathogenesis of Atherosclerosis

Background:

  • Atherosclerosis is a chronic inflammatory condition affecting the arterial wall.
  • Both innate and adaptive immune systems play a role in its development.
  • Innate immune cells are key players in atherosclerotic plaque inflammation.

Purpose of the Study:

  • To review the role of innate immune cells in atherosclerosis pathogenesis.
  • To discuss how these cells contribute to arterial wall inflammation and plaque evolution.

Main Methods:

  • Literature review focusing on innate immune cell involvement in atherosclerosis.
  • Analysis of signaling pathways and cellular mechanisms driving inflammation.
  • Examination of the contribution of specific innate immune cell types.

Main Results:

  • Innate immune cells like macrophages, mast cells, and neutrophils persist in atherosclerotic plaques.
  • Activation signals, including oxidized LDL and LPS, trigger pro-inflammatory cytokine secretion.
  • These cells contribute to foam cell formation and plaque progression.

Conclusions:

  • Innate immune system cells significantly influence the pathogenesis of atherosclerosis.
  • Understanding these cellular roles is crucial for developing targeted therapies.
  • Modulating innate immune responses may offer new avenues for treating atherosclerosis.
