Insights
Targeting alpha IIb beta 3 integrins is crucial for managing cardiovascular diseases. Inhibiting this platelet receptor reduces disease incidence and mortality, improving patient care and stimulating further research.
Area of Science:
- Cardiovascular Biology
- Integrin Signaling
- Thrombosis Research
Background:
- Cardiovascular diseases stem from abnormal cell interactions, leading to atherosclerosis and thrombus formation.
- Platelet activation and embolus formation are critical events in cardiovascular disease progression.
- Integrins, particularly platelet alpha IIb beta 3, play a significant role in these pathological processes.
Purpose of the Study:
- To highlight the importance of alpha IIb beta 3 integrin as a therapeutic target in cardiovascular diseases.
- To discuss the development and impact of alpha IIb beta 3 inhibitors on patient outcomes.
- To explore ongoing research into integrin function and novel inhibitor development for cardiovascular conditions.
Main Methods:
- Review of evidence supporting the role of alpha IIb beta 3 in cardiovascular disease.
- Analysis of the therapeutic strategy involving alpha IIb beta 3 inhibition.
- Examination of research advancements, including specific inhibitors and gene-ablated mouse models.
Main Results:
- Regulated inhibition of alpha IIb beta 3 integrin leads to reduced cardiovascular disease incidence and mortality.
- Alpha IIb beta 3 inhibitors have demonstrated improvements in patient care.
- Research has expanded to investigate integrins on other vascular cells and develop new inhibitors.
Conclusions:
- Alpha IIb beta 3 integrin is a validated and important therapeutic target for cardiovascular diseases.
- The development of alpha IIb beta 3 inhibitors represents a significant advancement in managing acute and chronic cardiovascular conditions.
- Continued research on integrins is vital for understanding cardiovascular system development and discovering novel therapeutic strategies.
Abstract:
Cardiovascular diseases involve abnormal cell-cell interactions leading to the development of atherosclerotic plaque, which when ruptured causes massive platelet activation and thrombus formation. Parts of a loose thrombus may detach to form an embolus, blocking circulation at a more distant point. The integrins are a family of adhesive cell receptors interacting with adhesive proteins or with counterreceptors on other cells. There is now solid evidence that the major integrin on platelets, the fibrinogen receptor alpha IIb beta 3, has an important role in several aspects of cardiovascular diseases and that its regulated inhibition leads to a reduction in incidence and mortality due to these disorders. The development of alpha IIb beta 3 inhibitors is an important strategy of many pharmaceutical companies which foresee a large market for the treatment of acute conditions in surgery, the symptoms of chronic conditions and, it is hoped, maybe even the successful prophylaxis of these conditions. Although all the associated problems have not been solved, the undoubted improvements in patient care resulting from the first of these treatments in the clinic have stimulated further research on the role of integrins on other vascular cells in these processes and in the search for new inhibitors. Both the development of specific inhibitors and of mice with specific integrin subunit genes ablated have contributed to a better understanding of the function of integrins in development of the cardiovascular system.

01:15Activation of Integrins
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.
