WebbThe diagnosis is confirmed by the finding that platelets fail to aggregate after exposure to epinephrine, collagen, or even high levels of ADP but do aggregate transiently after … Webb1 feb. 2002 · Beside ADP, other agonists, such as epinephrine, thrombin, collagen, and platelet-activating factor, can initiate platelet aggregation by interaction with membrane receptors. This platelet release reaction and aggregation lead to the recruitment of many other platelets to the vessel wall with the formation of a hemostatic platelet plug.

Platelet aggregation response in immune thrombocytopenia …
WebbIn clinical work, the method of measuring platelet aggregation function is often used to reflect the platelet activation state. 8 This method exposes platelets to different inducers (such as ADP, collagen, epinephrine, and AA) in vitro and uses light transmission aggregation measurement (LTA) to monitor platelet aggregation ability. WebbPhotoreceptor rod cells and blood platelets are remarkably different, yet both illustrate a similar phenomenon. Both are strongly affected by membrane cholesterol, and the distribution of cholesterol in the membranes of both cell types is determined. WebbThe diagnosis is confirmed by the finding that platelets fail to aggregate after exposure to epinephrine, collagen, or even high levels of ADP but do aggregate transiently after … clothespin picture holder
