Abstract:
The release of microvesicles ('platelet microparticles', PMPs) by activated platelets has been shown to be an integral part of the thrombotic process. PMPs are believed to mediate many biological processes as they possess various platelet membrane proteins and bioactive lipids. Of note, there is a growing body of evidence that PMPs are involved in all stages in the pathobiology of atherosclerosis. In addition to their role in thrombosis, PMPs may also have a pro-inflammatory effect, which promotes the development of atherosclerosis. Also, bioactive lipids in PMPs have been shown to have important effects on angiogenesis. This review summarises the various studies on the possible role of PMPs in the progression of atherosclerosis.
Insights
Platelet microparticles (PMPs) released by activated platelets contribute to thrombosis and atherosclerosis. This review explores the multifaceted roles of PMPs in the progression of atherosclerosis, including inflammation and angiogenesis.
Area of Science:
- Cardiovascular Biology
- Hematology
- Pathophysiology
Background:
- Activated platelets release microvesicles, termed platelet microparticles (PMPs).
- PMPs contain platelet membrane proteins and bioactive lipids, mediating various biological processes.
- Evidence suggests PMPs are implicated in all stages of atherosclerosis pathobiology.
Purpose of the Study:
- To review the literature on the role of PMPs in atherosclerosis progression.
- To summarize the known functions of PMPs in thrombotic and inflammatory processes relevant to atherosclerosis.
Main Methods:
- Literature review of studies investigating PMPs and atherosclerosis.
- Synthesis of findings on PMP involvement in thrombosis, inflammation, and angiogenesis.
Main Results:
- PMPs are integral to the thrombotic process.
- PMPs exhibit pro-inflammatory effects, promoting atherosclerosis development.
- Bioactive lipids within PMPs influence angiogenesis.
Conclusions:
- PMPs play a significant role in the progression of atherosclerosis.
- Understanding PMP functions offers insights into therapeutic strategies for atherosclerosis.

Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
