Summary
Investigating COVID-19 coagulopathy, this study found that genes related to blood coagulation are generally not affected by SARS-CoV-2 infection. Transferrin, however, shows potential links to COVID-19-related thrombosis.
Area of Science:
- * Molecular biology
- * Genetics
- * Immunology
Background:
- * Severe COVID-19 is linked to blood clotting disorders (coagulopathy) and thrombosis.
- * Risk factors for severe COVID-19 include male sex and older age.
- * Mechanisms of COVID-19 coagulopathy are not fully understood.
Purpose of the Study:
- * To identify gene products potentially contributing to COVID-19-related coagulopathy.
- * To analyze gene expression patterns in relation to sex and age.
- * To investigate gene expression changes in SARS-CoV-2 infected cells.
Main Methods:
- * Analysis of the Genotype-Tissue Expression (GTEx) database for genes associated with "blood coagulation".
- * Examination of a proteomics dataset from SARS-CoV-2 infected cells.
- * Comparison of gene expression based on sex and age.
Main Results:
- * Six genes (ADAMTS13, F11, HGFAC, KLKB1, C1QTNF1, SERPINA5) related to blood coagulation showed expression patterns influenced by sex and age but were not altered by SARS-CoV-2 infection.
- * These genes may predispose individuals to general thrombosis rather than directly causing COVID-19 coagulopathy.
- * Transferrin, a procoagulant not initially linked to blood coagulation, was upregulated in males, increased with age, and elevated upon SARS-CoV-2 infection.
Conclusions:
- * The studied blood coagulation genes do not appear to be directly involved in COVID-19 coagulopathy.
- * Transferrin warrants further investigation for its role in COVID-19-related thrombosis.
- * Understanding these mechanisms is crucial for managing severe COVID-19 cases.

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

9.2K
The coagulation phase is a critical part of the body's process to prevent blood loss following injury to blood vessels. It involves chemical reactions that form a clot to seal the injured area. The clotting process begins shortly after injury, within 15-20 seconds for severe damage and 1-2 minutes for minor injuries.
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...

1.0K
Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

01:28The Early Endosome: Endocytosis of Transferrin
4.5K
Essential proteins such as insulin or low-density lipoprotein (LDL) and micronutrients such as iron enter a eukaryotic cell through receptor-mediated endocytosis. Subsequently, the early endosomes fuse with the vesicles containing such receptor-ligand complexes and play a vital role in sorting the incoming ligands and receptors. While the ligands are either degraded inside the vesicle or released into the cytosol, their receptors are returned to the plasma membrane for further rounds of...

01:24Disorders of Hemostasis
1.7K
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.

Two factors primarily cause thromboembolic conditions.
