Platelets are an organ with hematopoietic function, and the birthplace of blood is platelets. There are thousands of platelets distributed in the body, and the blood produced by these platelets promotes the metabolism of blood in the body. Platelets can help the body produce blood, but they also have antibodies. So, what does platelet antibody mean?
What does platelet antibody mean
1. Platelet antibodies are immune proteins produced by the human body against self antigens. Platelets, as self antigens, bind to antibodies, causing phagocytic cells to engulf them. Antiplatelet antibodies are autoantibodies that refer to antibodies against one's own tissues, organs, cells, and cellular components.
2. Autoantibodies, due to their inability to recognize their own tissues and organs, can attack them and cause damage. Normal human blood can have low levels of autoantibodies, but diseases do not occur. However, if the titer of autoantibodies exceeds a certain level, it may cause damage to the body and trigger diseases.
What is platelet function
1. The main functions of platelets are coagulation and hemostasis, as well as repairing damaged blood vessels. The surface sugar coating of platelets can adsorb plasma proteins and coagulation factors, and platelet particles contain substances related to coagulation. When blood vessels are damaged or ruptured, platelets are stimulated and undergo a phase transition from static to functional, quickly deforming, increasing surface viscosity, and aggregating into clusters.
2. At the same time, under the action of surface factors, prothrombin in the plasma is converted into thrombin, which in turn catalyzes the transformation of fibrinogen into filamentous fibrin, forming a clot together with blood cells to stop bleeding. The release of platelet particulate matter further promotes hemostasis and coagulation.
Platelet antibodies can be said to be the innate healing elixir of the human body, which cannot be compared to any other medication. It can not only quickly stop bleeding from cut wounds, but also prevent people from being infected. It can be seen that the platelet antibodies in the human body are really good. If these antibodies are relatively low, it is easy to cause heavy bleeding.
