Platelets are crucial immune cells, not just for blood clotting. Emerging research highlights their significant role in inflammation, atherosclerosis, and various diseases, impacting all immune responses.
Area of Science:
- Immunology
- Hematology
- Vascular Biology
Background:
- Platelets traditionally recognized for thrombosis.
- Emerging evidence shows significant immune modulatory functions.
- Platelet roles extend beyond acute thrombotic events.
Purpose of the Study:
- To highlight the immune regulatory roles of platelets.
- To emphasize platelet involvement in inflammatory processes.
- To underscore platelets as critical immune cells in various pathologies.
Main Methods:
- Review of current scientific literature.
- Analysis of recent studies on platelet function.
- Synthesis of data on platelet impact in diverse diseases.
Main Results:
- Platelets initiate and accelerate inflammation in atherosclerosis and myocardial infarction.
- Platelets are implicated in autoimmune diseases, sepsis, and viral infections.
- Platelets influence tumor growth and metastasis.
Conclusions:
- Platelets possess significant immune modulatory functions.
- Platelets are integral to the pathogenesis of numerous vascular inflammatory conditions.
- Platelets should be considered key immune cells affecting all phases of immune responses.

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...
