Extrinsic and Intrinsic Pathways of Hemostasis01:20

Extrinsic and Intrinsic Pathways of Hemostasis

11.9K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Coagulation

9.5K
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...

Coagulation01:06

Coagulation

1.2K
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...

Introduction to Hemostasis

13.2K
Hemostasis is a complex physiological process that prevents excessive bleeding when a blood vessel is injured. It's crucial for maintaining the integrity of the circulatory system, as it ensures that our blood remains fluid while still within the vascular network and yet clots to prevent blood loss upon vessel injury.
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...

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...

Phases of Wound Repair01:28

Phases of Wound Repair

7.8K
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Area of Science:

  • Biochemistry
  • Immunology
  • Hematology

Background:

  • Tissue injury releases damage-associated molecular patterns (DAMPs) into circulation.
  • DAMPs are recognized as potent procoagulant molecules influencing hemostasis and thrombosis.
  • DAMPs bridge coagulation and innate immunity, contributing to immunothrombosis.

Purpose of the Study:

  • To explore the role of DAMPs in linking coagulation and immunity.
  • To investigate DAMPs' procoagulant activity in various phases of coagulation.
  • To identify DAMPs as potential therapeutic targets in critical illnesses.

Main Methods:

  • Review of existing literature on DAMPs, coagulation, and inflammation.
  • Analysis of DAMPs' functions in the cell-based model of coagulation.
  • Examination of DAMPs' impact on inflammatory and immune responses.

Main Results:

  • DAMPs exhibit significant procoagulant activity, affecting all stages of coagulation.
  • DAMPs modulate both traditional hemostatic and inflammatory pathways.
  • DAMPs are central to the development of immunothrombosis in critical conditions.

Conclusions:

  • DAMPs represent a critical interface between coagulation and immunity.
  • Targeting DAMPs offers potential for novel diagnostics and therapeutics.
  • Interventions at the DAMPs-immunity-coagulation nexus may benefit patients with coexisting coagulopathy and hyperinflammation.
