What is ADP receptor
ADP receptor is an important protein on the cell surface and is mainly involved in the activation and aggregation of platelets. It plays a key role in hemostasis and thrombosis and is an important target for antiplatelet drugs. This article will introduce in detail the definition, classification, function and related research progress of ADP receptors.
1. Definition and classification of ADP receptors
ADP receptor, full nameAdenosine Diphosphate Receptor, is a type of membrane protein that can specifically bind to ADP molecules. According to different structures and functions, ADP receptors are mainly divided into the following two categories:
| Receptor type | Alias | Main functions |
|---|---|---|
| P2Y1 | G protein coupled receptor | Mediates platelet shape changes and initial aggregation |
| P2Y12 | Gi coupled receptor | Promote continuous activation and aggregation of platelets |
2. Function and mechanism of action of ADP receptor
ADP receptors play a central role in platelet activation. When blood vessels are damaged, platelets release ADP, which binds to receptors and triggers the following reactions:
1.P2Y1 receptor activation: Causes the release of calcium ions through the Gq protein pathway, resulting in platelet shape changes and initial aggregation.
2.P2Y12 receptor activation: Inhibits adenylyl cyclase through the Gi protein pathway, reduces cAMP levels, and promotes continued platelet activation.
| receptor | signaling pathway | effect |
|---|---|---|
| P2Y1 | Gq-PLC-IP3 | Calcium ions are released and platelets deform |
| P2Y12 | Gi-AC-cAMP | Continued activation of platelets |
3. The relationship between ADP receptors and diseases
Abnormal ADP receptor function is associated with a variety of diseases, especially cardiovascular disease:
1.Thrombotic disease: Excessive activation of ADP receptors can lead to abnormal aggregation of platelets and the formation of thrombus.
2.bleeding disorders: ADP receptor deficiency or inhibition may lead to bleeding tendencies.
3.drug target: The P2Y12 receptor is the main target of antiplatelet drugs (such as clopidogrel).
4. Latest progress in ADP receptor research (hot spots in the past 10 days)
