T Cells in Autoimmunity-Associated Cardiovascular Diseases

Area of Science:

• Immunology
• Cardiovascular Medicine
• Rheumatology

Background:

• T cells are key mediators of atherosclerotic cardiovascular disease (CVD), secreting pro-inflammatory cytokines that worsen vascular pathology.
• Autoimmune diseases, driven by autoreactive T cells, substantially increase CVD risk, making CVD a leading cause of death in these patients.
• Effective immunomodulatory treatments for autoimmune diseases have inadvertently increased the focus on CVD as a primary mortality cause.

Purpose of the Study:

• To investigate the mechanisms by which autoreactive T cells contribute to CVD in the context of autoimmune diseases.
• To explore the role of T cells in the increased CVD risk associated with systemic vasculitides, lupus, rheumatoid arthritis, and psoriasis.
• To identify T cells as potential therapeutic targets for preventing and treating CVD in autoimmune disease patients.

Main Methods:

• Review of existing literature on T cell involvement in CVD pathogenesis.
• Analysis of T cell roles in systemic vasculitides, lupus, rheumatoid arthritis, and psoriasis.
• Investigation of T cell-derived cytokines in psoriatic CVD.

Main Results:

• T cells are critical mediators of atherosclerotic CVD through pro-inflammatory cytokine secretion.
• Autoreactive T cells in autoimmune diseases are increasingly recognized as contributors to CVD.
• T cell involvement in CVD is observed in systemic vasculitides, lupus, rheumatoid arthritis, and psoriasis.

Conclusions:

• T cells play a central role in the pathogenesis of CVD, particularly in the context of autoimmune diseases.
• Understanding T cell mechanisms in autoimmune-driven CVD is crucial for improving patient outcomes.
• T cells represent promising targets for future therapeutic strategies aimed at reducing CVD in autoimmune disease populations.
