Atherosclerosis I: Introduction

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...

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Coronary Artery Disease II: Pathophysiology

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...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

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)...

T Cell Types and Functions

T Cell Types and Functions

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:

Cardiovascular Science
Immunology

Background:

Atherosclerosis is a chronic inflammatory disease involving lipid accumulation and immune activation.
Dyslipidemia, a hallmark of atherosclerosis, can disrupt normal immune cell function.
Natural killer T (NKT) cells are unique immune cells recognizing glycolipid antigens and producing diverse cytokines.

Purpose of the Study:

To review current knowledge on NKT cells.
To discuss the interplay between dyslipidemia and NKT cell function.
To explore how NKT cells modulate inflammation and atherosclerosis.

Main Methods:

Literature review of NKT cell function in cardiovascular disease.
Analysis of the relationship between dyslipidemia and immune regulation.
Synthesis of current research on NKT cells in atherosclerosis.

Main Results:

NKT cells possess unique characteristics, bridging lipid metabolism and immune responses.
Dyslipidemia can alter NKT cell function, impacting inflammatory pathways.
NKT cells play a regulatory role in immunity and inflammation relevant to cardiovascular disease.

Conclusions:

NKT cells are crucial in the immune response to dyslipidemia.
Targeting NKT cells may offer novel therapeutic strategies for atherosclerosis.
Further research into NKT cell function is warranted for cardiovascular disease management.
