Interleukins and Cardiovascular Disease

Area of Science:

• Cardiovascular Science
• Immunology
• Cytokine Biology

Background:

• Interleukins are key inflammatory cytokines implicated in cardiovascular disease (CVD) pathogenesis.
• They regulate critical processes including inflammation, endothelial dysfunction, plaque formation, thrombosis, immune responses, and hematopoiesis.

Purpose of the Study:

• To detail the role of specific interleukins, particularly IL-6 and IL-1β, in CVD.
• To explore their potential as therapeutic targets and biomarkers for cardioprotective strategies.

Main Methods:

• Review and synthesis of existing literature on interleukins in CVD.
• Analysis of the association between IL-6 and IL-1β levels and adverse cardiovascular outcomes.
• Discussion of the therapeutic potential of interleukin inhibitors.

Main Results:

• High levels of IL-6 and IL-1β correlate strongly with atherosclerosis progression, adverse CV events, peripheral artery disease, heart failure, and mortality.
• Lowering IL-6 activity shows potential for CV risk reduction without increasing infection risk.
• Interleukins also play roles in hypertension, cardiac arrhythmias, and stroke.

Conclusions:

• Interleukins are significant players in CVD pathogenesis and progression.
• IL-6 and IL-1β are valuable biomarkers and therapeutic targets for developing novel cardioprotective therapies.
• Inhibitors of these interleukins demonstrate protective effects in cardiovascular conditions.
