Summary
Leukocytes and red cells play an underestimated role in thrombogenesis, particularly in hematologic diseases. Targeting these cells may reduce thrombotic complications beyond traditional anticoagulants.
Area of Science:
- Hematology
- Thrombosis Research
- Cellular Biology
Background:
- Thrombophilia knowledge has advanced, but the roles of leukocytes and red cells in thrombosis remain unclear.
- Thrombosis is a significant complication in myeloproliferative disorders and certain hemolytic anemias.
- Leukocyte and red cell activation contribute to endothelial damage and hypercoagulability.
Purpose of the Study:
- To review the contribution of leukocytes and red cells to thrombogenesis.
- To examine the prevalence of thrombosis in hematologic diseases.
- To explore novel therapeutic targets for thrombotic complications.
Main Methods:
- Literature review using PubMed.
- Examination of thrombosis in various hematologic conditions.
- Analysis of cellular mechanisms in thrombogenesis.
Main Results:
- Leukocyte activation and red cell phosphatidylserine exposure promote thrombosis.
- Thrombosis is a key issue in polycythemia vera, essential thrombocythemia, paroxysmal nocturnal hemoglobinuria, and drepanocytosis.
- Leukocytes and red cells contribute to thrombosis beyond plasma alterations.
Conclusions:
- Thrombotic complications in hematologic diseases can be reduced by targeting leukocyte and red cell activation.
- Inhibiting leukocyte and red cell activation offers a complementary strategy to anticoagulants and antiplatelet agents.
- Further research into cellular mechanisms can lead to improved thrombosis management.

02:45Blood Transfusion and Agglutination
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...

01:30Anticoagulant Drugs: Low-Molecular-Weight Heparins
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...
01:26Characteristics and Functions of Blood
Blood is specialized connective tissue comprising about 8% of the body mass. It has a thick, liquid extracellular matrix that contains cells, dissolved proteins, and electrolytes, making it five times more viscous than water. Blood is warm, around 38°C, and has an alkaline pH ranging from 7.35 to 7.45.
The primary function of blood is to transport oxygen and carbon dioxide between tissues and the lungs. Oxygenated blood is bright red, while oxygen-depleted blood is darker. It also carries...

01:27Disorders of Erythrocytes
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...

01:27Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

01:24Disorders of Hemostasis
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.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
