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...

Proteomics

7.5K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Formation of the Platelet Plug

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...

Area of Science:

  • Hematology and Molecular Biology
  • Platelet biology and transcriptomics
  • Proteomics and genomics

Background:

  • Anucleate human platelets possess a wide array of messenger RNAs (mRNAs) and other RNA transcripts.
  • Quantitative similarities in mRNA between megakaryocytes and platelets suggest a common origin and random redistribution during proplatelet formation.

Purpose of the Study:

  • To compare the classified platelet transcriptome with the identified platelet proteome.
  • To discuss challenges and possibilities for achieving a complete, genome-wide platelet transcriptome and proteome.
  • To explore applications in understanding intra- and inter-subject platelet differences and aiding genetic diagnostics.

Main Methods:

  • Classification of the platelet transcriptome (17.6k transcripts).
  • Identification of the platelet proteome (5.2k proteins).
  • Comparative analysis of transcriptome and proteome data.

Main Results:

  • The platelet proteome shows under-representation of nuclear proteins (unlike other organellar proteins).
  • Membrane receptors/channels with low transcript levels, transcription/translation proteins, and uncharacterized proteins are also under-represented.
  • Significant technical, normalization, and database-dependent challenges exist in generating comprehensive platelet molecular profiles.

Conclusions:

  • A complete, genome-wide reference platelet transcriptome and proteome are crucial for further research.
  • Such reference data will aid in elucidating platelet variations in health and disease.
  • Potential applications include advancing genetic diagnostics and understanding platelet function.
