Insights
Atherosclerosis underlies cardiovascular and cerebrovascular diseases. This review explores the TSP-1/CD47/VEGF/VEGFR2 pathway and inflammatory factors like IL-1 and NLRP3 as key players in atherosclerosis pathogenesis.
Area of Science:
- Cardiovascular biology
- Molecular mechanisms of disease
- Inflammation research
Background:
- Atherosclerosis leads to debilitating cardiovascular and cerebrovascular diseases.
- Understanding atherosclerosis mechanisms is crucial for disease control and prevention.
- Thrombospondin-1 (TSP-1) exhibits antiangiogenic properties, interacting with its receptor CD47.
Purpose of the Study:
- To review the pathogenesis of atherosclerosis.
- To elucidate the role of the TSP-1/CD47/VEGF/VEGFR2 signaling pathway in atherosclerosis.
- To examine the influence of inflammatory factors on atherosclerosis progression.
Main Methods:
- Literature review focusing on molecular and cellular mechanisms.
- Analysis of signaling pathways involved in angiogenesis and inflammation.
- Synthesis of current research on atherosclerosis pathogenesis.
Main Results:
- TSP-1/CD47 signaling negatively regulates angiogenesis by affecting VEGF and its downstream targets.
- The TSP-1/CD47/VEGF/VEGFR2 axis is implicated in the development and progression of atherosclerosis.
- Inflammatory factors, including IL-1 and NLRP3, significantly impact atherosclerotic processes.
Conclusions:
- The TSP-1/CD47/VEGF/VEGFR2 pathway represents a critical target for modulating atherosclerosis.
- Inflammation plays a pivotal role in atherosclerosis pathogenesis.
- Further research into these pathways may reveal novel therapeutic strategies for cardiovascular and cerebrovascular diseases.
Abstract:
Cardiovascular and cerebrovascular diseases caused by atherosclerosis have a high disability rate and reduce the quality of life of the population. Therefore, understanding the mechanism of atherosclerosis and its control may interfere with the progression of atherosclerosis and thus control the occurrence of diseases closely related to atherosclerosis. TSP-1 is a factor that has been found to have an antiangiogenic effect, and CD47, as the receptor of TSP-1, can participate in the regulation of antiangiogenesis of atherosclerosis. VEGF is an important regulator of angiogenesis, and TSP-1/CD47 can cause VEGF and its downstream expression. Therefore, the TSP-1/CD47/VEGF/VEGFR2 signal may have an important influence on atherosclerosis. In addition, some inflammatory factors, such as IL-1 and NLRP3, can also affect atherosclerosis. This review will be expounded focusing on the pathogenesis and influencing factors of atherosclerosis.
