The many faces of CD8+ T cells in atherosclerosis

Area of Science:

• Immunology
• Cardiovascular Research
• Pathogenesis of Atherosclerosis

Background:

• Atherosclerosis and cardiovascular disease are leading global causes of death.
• Immune responses and elevated cholesterol levels are key drivers of atherosclerosis.
• The specific roles of CD8 T cells in atherosclerosis remain under-investigated.

Purpose of the Study:

• To review the multifaceted roles of CD8 T cells in atherosclerosis.
• To explore therapeutic strategies targeting CD8 T cells for atherosclerosis treatment.

Main Methods:

• Literature review of existing research on CD8 T cells in atherosclerosis.
• Analysis of both pro-atherogenic and atheroprotective functions of CD8 T cells.

Main Results:

• CD8 T cells exhibit dual roles: promoting inflammation and lesion instability via cytokine production and cytotoxicity, but also potentially limiting atherosclerosis through regulatory functions and targeting antigen-presenting cells.
• Evidence suggests both detrimental and beneficial impacts of CD8 T cells on atherosclerotic lesion progression.

Conclusions:

• CD8 T cells significantly influence atherosclerosis pathogenesis through complex mechanisms.
• Targeting specific CD8 T cell subsets presents a promising therapeutic avenue for managing atherosclerotic burden and cardiovascular disease.
