Insights
Macrophages, key inflammatory cells, drive vascular calcification by altering phenotypes. Targeting macrophage polarization offers a promising therapeutic strategy for cardiovascular and cerebrovascular diseases.
Area of Science:
- Cardiovascular Science
- Immunology
- Pathology
Background:
- Vascular calcification significantly contributes to cardiovascular and cerebrovascular disease morbidity and mortality.
- Calcification of the vascular intima or media disrupts normal vascular wall function.
- Inflammation is a critical driver in the development of vascular calcification.
Purpose of the Study:
- To review the role of macrophage polarization in vascular calcification.
- To explore the interaction between macrophage phenotypes and the calcification environment.
- To discuss therapeutic strategies targeting macrophage polarization for vascular calcification.
Main Methods:
- Literature review focusing on macrophage polarization in vascular calcification.
- Analysis of the mechanisms by which macrophages influence vascular calcification.
- Examination of therapeutic interventions targeting macrophage polarization.
Main Results:
- Macrophages, as primary inflammatory cells, exhibit dynamic phenotypic changes crucial to calcification.
- Different macrophage phenotypes interact with the vascular calcification environment.
- Macrophages promote vascular calcification via inflammatory mediators and smooth muscle cell osteogenic transdifferentiation.
Conclusions:
- Macrophage polarization is central to vascular calcification.
- Understanding macrophage phenotypes and their interactions is key to managing vascular calcification.
- Targeting macrophage polarization presents a significant therapeutic avenue for vascular calcification.
Abstract:
Vascular calcification is an important factor in the high morbidity and mortality of Cardiovascular and cerebrovascular diseases. Vascular damage caused by calcification of the intima or media impairs the physiological function of the vascular wall. Inflammation is a central factor in the development of vascular calcification. Macrophages are the main inflammatory cells. Dynamic changes of macrophages with different phenotypes play an important role in the occurrence, progression and stability of calcification. This review focuses on macrophage polarization and the relationship between macrophages of different phenotypes and calcification environment, as well as the mechanism of interaction, it is considered that macrophages can promote vascular calcification by releasing inflammatory mediators and promoting the osteogenic transdifferentiation of smooth muscle cells and so on. In addition, several therapeutic strategies aimed at macrophage polarization for vascular calcification are described, which are of great significance for targeted treatment of vascular calcification.
