Readapting the adaptive immune response - therapeutic strategies for atherosclerosis

Area of Science:

• Immunology
• Cardiovascular Medicine
• Inflammation Research

Background:

• Cardiovascular diseases (CVDs) are a major global health concern, with atherosclerosis as a primary driver.
• While CVD treatments have advanced, significant challenges remain in reducing disease burden and preventing plaque complications.
• Inflammation and the adaptive immune system play crucial roles in all stages of atherosclerosis, presenting therapeutic targets.

Purpose of the Study:

• To explore the role of the adaptive immune system in atherosclerosis development and progression.
• To identify potential therapeutic targets within immune pathways for cardiovascular disease management.
• To review emerging strategies, including vaccine-based therapies and existing immune-modulating treatments, for their impact on CVD.

Main Methods:

• Review of current understanding of immune system involvement in atherosclerosis.
• Analysis of protective immune mechanisms, such as humoral responses to modified LDL and regulatory T cell function.
• Examination of existing adaptive immune-targeting therapies and their cardiovascular effects.

Main Results:

• The atherosclerotic vascular wall is influenced by adaptive immunity from both the lumen and adventitia.
• Defective protective immune responses, like those involving regulatory T cells, are implicated in disease.
• Early data on therapies targeting co-stimulatory pathways and B cells show emerging cardiovascular consequences.

Conclusions:

• Targeting adaptive immune responses presents a promising frontier for reducing atherosclerosis advancement and preventing plaque rupture.
• Therapeutic strategies, including boosting protective immune pathways and utilizing existing immune-modulating treatments, hold potential for broader application in CVD.
• The translation of adaptive immune-targeting therapies into clinical practice for cardiovascular disease is an exciting prospect.
