Insights
Atherosclerosis, a leading cause of death, involves inflammatory interactions between lipoproteins and arterial wall cells. This review focuses on macrophages and dendritic cells (DCs) in atherosclerosis development and regression.
Area of Science:
- Cardiovascular Biology
- Immunology
- Pathology
Background:
- Atherosclerosis is the primary cause of mortality in Western countries.
- It arises from interactions between modified lipoproteins and cells within the arterial wall, including macrophages and dendritic cells (DCs).
- This inflammatory process leads to arterial plaque formation, potentially causing myocardial infarction or stroke.
Purpose of the Study:
- To review the roles of macrophages and dendritic cells (DCs) in atherosclerosis pathogenesis.
- To emphasize the involvement of these cells in the regression of atherosclerotic lesions.
Main Methods:
- Literature review focusing on cellular and molecular mechanisms.
- Analysis of the involvement of macrophages and DCs in atherosclerotic plaque development.
- Examination of cellular contributions to atherosclerosis regression.
Main Results:
- Macrophages and DCs are key cellular players in the inflammatory cascade of atherosclerosis.
- These cells influence both the progression and potential regression of atherosclerotic plaques.
- Understanding their specific roles is crucial for therapeutic strategies.
Conclusions:
- Macrophages and DCs are central to atherosclerosis pathogenesis.
- Targeting these cells may offer novel approaches for promoting atherosclerosis regression.
- Further research into the specific functions of macrophages and DCs in regression is warranted.
Abstract:
Atherosclerosis is the number one cause of death in the Western world. It results from the interaction between modified lipoproteins and cells such as macrophages, dendritic cells (DCs), T cells, and other cellular elements present in the arterial wall. This inflammatory process can ultimately lead to the development of complex lesions, or plaques, that protrude into the arterial lumen. Ultimately, plaque rupture and thrombosis can occur leading to the clinical complications of myocardial infarction or stroke. Although each of the cell types plays roles in the pathogenesis of atherosclerosis, the focus of this review will be primarily on the macrophages and DCs. The role of these two cell types in atherosclerosis is discussed, with a particular emphasis on their involvement in atherosclerosis regression.
