Summary
Platelet microvesicles (PMVs) are key intercellular communicators, influencing various blood and vessel cells. This review explores their diverse signaling mechanisms and roles in cellular communication.
Area of Science:
- Cellular Biology
- Hematology
- Vascular Biology
Background:
- Microvesicles, initially termed 'platelet dust,' have gained significant research interest.
- Platelet microvesicles (PMVs) are recognized as crucial mediators of intercellular communication.
Purpose of the Study:
- To review the communicative properties of platelet microvesicles (PMVs).
- To highlight the expanding role of PMVs in cell-to-cell signaling.
Main Methods:
- Literature review focusing on recent publications regarding PMVs.
- Analysis of studies detailing PMV interactions with various cell types.
Main Results:
- PMVs exert physiological effects on hematological and vascular cells, including monocytes, macrophages, neutrophils, T-cells, endothelial cells, and smooth muscle cells.
- PMVs mediate communication through receptor signaling, surface molecule transfer, and intracellular content delivery (e.g., miRNA).
- Evidence suggests multi-directional sharing of cellular contents between cell types via PMVs.
Conclusions:
- Platelet microvesicles are versatile signaling agents with broad physiological impact.
- Understanding PMV communication is vital for comprehending complex cellular interactions in hematological and vascular systems.

The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
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...

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

3.8K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

01:36Overview of Exosomes
3.8K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.

60.1K
Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. Such a signal can only trigger a response in nearby target cells because the signal molecules degrade quickly or are inactivated if not taken up. Prominent examples of paracrine signaling include nitric oxide signaling in blood vessels, synaptic signaling of neurons, the blood clotting system, tissue repair/wound healing, and local allergic skin reactions. Nitric oxide as a...

In multicellular organisms, many molecules transmit signals between cells to pass information. These signals vary in complexity and include small peptides, nucleotides, steroids, fatty acid derivatives, and dissolved gases such as nitric oxide. Some signaling molecules diffuse through the plasma membrane to act locally between neighboring cells or travel long distances. Others remain attached to the cell surface, transmitting information to other cells only when they make contact. In some...
