Immune communication between the intestinal microbiota and the cardiovascular system

Area of Science:

• Immunology
• Microbiology
• Cardiology

Background:

• The gut microbiome significantly impacts host immunity and cardiovascular health.
• Immune cell infiltration in the gut and heart is a hallmark of cardiovascular diseases (CVD).
• Gut microbiota-derived metabolites influence immune responses relevant to CVD.

Approach:

• This review synthesizes current research on the interplay between gut microbiota, immune cells, and cardiac function.
• It examines the role of immune cells, including T cells, B cells, and macrophages, in gut-heart communication.
• The review highlights the bidirectional communication pathways modulated by microbial communities.

Key Points:

• Gut microbiota critically influences immune cell activity in both the intestine and heart.
• Immune cells mediate the crosstalk between the gut microbiome and cardiovascular system.
• Microbial metabolites are key mediators in the gut-heart axis during CVD.

Conclusions:

• Immune cell networks in the gut and heart are crucial in the pathogenesis of CVD.
• Targeting the gut microbiota-immune cell axis presents novel therapeutic strategies for CVD.
• Further research into this axis can lead to innovative treatments for myocardial infarction and atherosclerosis.
