Structure and Function of Platelets01:18

Structure and Function of Platelets

1.3K
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...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

583
Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...

Area of Science:

  • Hematology
  • Thrombosis research
  • Platelet biology

Background:

  • Platelet ageing is a growing research area with implications for health and disease.
  • Newly formed platelets (reticulated platelets) are RNA-enriched and often considered hyper-reactive.
  • Increased young platelets correlate with thrombotic events and reduced anti-platelet therapy efficacy.

Approach:

  • Reviewing existing research on platelet subpopulations (function, size, age).
  • Focusing on intrinsic changes during natural platelet ageing in circulation.
  • Evaluating experimental methodologies and conclusion robustness in platelet ageing studies.

Key Points:

  • Young platelets are RNA-rich and associated with increased thrombotic risk.
  • Ageing platelets undergo intrinsic changes affecting lifespan and reactivity.
  • Research highlights platelet subpopulations but intrinsic ageing mechanisms require further exploration.

Conclusions:

  • Understanding natural platelet ageing is crucial for identifying triggers of altered platelet lifespan and reactivity.
  • Further research into intrinsic platelet ageing processes is needed.
  • This review examines current knowledge and experimental approaches in platelet ageing research.
