Innate and adaptive immunity in atherosclerosis

Area of Science:

• Cardiovascular Biology
• Immunology
• Molecular Medicine

Background:

• Atherosclerosis is a chronic inflammatory disease affecting large and medium arteries.
• It involves subendothelial accumulation of cholesterol, immune cells, and extracellular matrix.
• Endothelial dysfunction marks the early stage of atherogenesis.

Purpose of the Study:

• To provide an overview of the atherogenesis process.
• To describe the role of damage-associated molecular patterns (DAMPs) in atherosclerosis.
• To highlight the involvement of NLRP3 inflammasome activation and immune cells in disease progression.

Main Methods:

• This is a review article, synthesizing existing research.
• It focuses on the molecular and cellular mechanisms of atherogenesis.
• Key pathways discussed include DAMPs, inflammasomes, and immune cell activation.

Main Results:

• Low-density lipoproteins can act as DAMPs, initiating inflammation.
• Innate immune cells, like monocytes and macrophages, are crucial early responders.
• Adaptive immune responses further promote atherosclerotic plaque development.

Conclusions:

• DAMPs, NLRP3 inflammasome activation, and both innate and adaptive immunity are integral to atherogenesis.
• Targeting these pathways may offer therapeutic strategies for atherosclerosis.
• Further research into immune-mediated mechanisms is warranted.
