Insights
Atherosclerosis, a vascular disease, impacts numerous organs by altering local immunity and vascular function. Understanding these connections offers new therapeutic avenues for cardiovascular disease (CVD).
Area of Science:
- Cardiovascular Science
- Immunology
- Pathology
Background:
- Atherosclerosis is a chronic inflammatory vascular disease.
- It involves lipoprotein deposition, immune cell accumulation, and fibrous tissue formation.
- This disease affects nearly all organs, impacting their functions.
Purpose of the Study:
- To review how atherosclerosis interferes with organ functions.
- To explore the role of immune disturbances in atherosclerosis-related multi-organ dysfunction.
- To highlight potential new therapeutic strategies for cardiovascular disease (CVD).
Main Methods:
- Literature review of atherosclerosis and its systemic effects.
- Analysis of common pathways linking atherosclerosis to organ dysfunction.
- Examination of immune system dysregulation in atherosclerosis.
Main Results:
- Atherosclerosis impacts organ function through local vascular changes, cholesterol pathologies, and immune responses.
- Immune system disturbances in atherosclerosis contribute to dysfunction in multiple tissues.
- The disease's microenvironment plays a critical role in multi-organ pathology.
Conclusions:
- Atherosclerosis is a systemic disease with widespread organ implications.
- Understanding atherosclerosis-induced immune dysregulation is key to addressing multi-organ pathology.
- This knowledge can lead to novel therapeutic opportunities for CVD.
Abstract:
Atherosclerosis is a chronic inflammatory disease of the vascular system that is characterized by the deposition of modified lipoproteins, accumulation of immune cells, and formation of fibrous tissue within the vessel wall. The disease occurs in vessels throughout the body and affects the functions of almost all organs including the lymphoid system, bone marrow, heart, brain, pancreas, adipose tissue, liver, kidneys, and gastrointestinal tract. Atherosclerosis and associated factors influence these tissues via the modulation of local vascular functions, induction of cholesterol-associated pathologies, and regulation of local immune responses. In this review, we discuss how atherosclerosis interferers with functions of different organs via several common pathways and how the disturbance of immunity in atherosclerosis can result in disease-provoking dysfunctions in multiple tissues. Our growing appreciation of the implication of atherosclerosis and associated microenvironmental conditions in the multi-organ pathology promises to influence our understanding of CVD-associated disease pathologies and to provide new therapeutic opportunities.
