Abstract:
Although a growing number of studies suggest that microRNAs (miRNAs) play a relevant role in platelet biology, their implications in bleeding diatheses are starting to be investigated. Indeed, several studies have shown that alterations in the intracellular levels of highly expressed platelet miRNAs provoke a thrombotic phenotype. On the other hand, primary immune thrombocytopenia (ITP), which is considered the hallmark of acquired bleeding disorders, has been recently associated with altered levels of miRNAs in peripheral blood mononuclear cells, plasma, and platelets. In this review, we will focus on miRNAs that may affect the hemostatic and thrombotic functions of platelets, and we will discuss the different studies that have attempted to associate miRNAs with regulatory mechanisms of ITP.
Insights
MicroRNAs (miRNAs) are increasingly linked to platelet function and bleeding disorders. This review explores how platelet miRNAs influence hemostasis and their potential role in immune thrombocytopenia (ITP).
Area of Science:
- Hematology
- Molecular Biology
- Genetics
Background:
- Platelet biology is increasingly understood to involve microRNAs (miRNAs).
- Alterations in platelet miRNA levels are linked to thrombotic phenotypes.
- Immune thrombocytopenia (ITP) is a primary acquired bleeding disorder associated with altered miRNA levels.
Purpose of the Study:
- To review the role of miRNAs in platelet hemostatic and thrombotic functions.
- To discuss the association between miRNAs and the regulatory mechanisms of immune thrombocytopenia (ITP).
Main Methods:
- Literature review of studies on miRNAs, platelet function, and bleeding disorders.
- Analysis of research linking miRNA alterations to thrombotic phenotypes.
- Examination of studies associating miRNAs with primary immune thrombocytopenia (ITP).
Main Results:
- Platelet miRNAs significantly impact hemostatic and thrombotic processes.
- Altered intracellular levels of highly expressed platelet miRNAs can lead to a thrombotic state.
- Evidence suggests a connection between altered miRNA levels in various biological samples and ITP.
Conclusions:
- MicroRNAs are critical regulators of platelet function with implications for bleeding diatheses.
- Further investigation into miRNA regulatory mechanisms in ITP is warranted.
- Targeting specific miRNAs may offer new therapeutic strategies for ITP and other bleeding disorders.

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...
