This review explores the role of platelets as key players in the regulation of brain-derived neurotrophic factor (BDNF), a crucial neurotrophin involved in neuronal survival, synaptic plasticity, and vascular health. BDNF is stored in large quantities in platelets, which release it upon activation, particularly in response to vascular injury. Platelet activation and aggregation involve the binding of BDNF to its receptor, tropomyosin-related kinase B (TrkB), facilitating the formation of a more porous fibrin clot and enhancing the healing process in vascular lesions. Additionally, BDNF has been found to reduce the risk of adverse cardiovascular and cerebrovascular outcomes, highlighting its protective role in vascular health.
The release of BDNF into circulation is tightly regulated to prevent excessive platelet activation. A key mechanism involves α2-macroglobulin binding to BDNF, limiting its platelet-activating effects to the site of injury. Studies suggest that platelets not only play a role in hemostasis but also act as reservoirs of neurotrophins, contributing to the maintenance of endothelial health and overall cardiovascular function.
The study also discusses BDNF's dual role in hemostasis and thrombosis, where it promotes platelet aggregation but also mitigates vascular damage, thus reducing cardiovascular burden. Furthermore, platelet-derived BDNF may provide a protective mechanism against cognitive decline, establishing a link between cardiovascular health and neuroprotection. This opens up new therapeutic avenues for leveraging platelet-based strategies to deliver BDNF to vascular lesions, thereby facilitating tissue regeneration.
potential of platelet-derived BDNF in promoting tissue repair and modulating vascular health aligns well with the regenerative aims of Novastem's stem cell therapies. PRP (platelet-rich plasma) therapies, widely used in regenerative medicine, could benefit from the insights gained in this study. By regulating BDNF and optimizing its release, stem cell-based therapies may be enhanced to further support neurovascular repair and cognitive health, particularly in patients with cardiovascular or neurodegenerative conditions.
- Mechanism of Action: BDNF stored in platelets is released upon activation and binds to its receptor TrkB, promoting platelet aggregation and vascular healing while reducing cardiovascular risks.
- Clinical Benefits: Platelet-derived BDNF improves vascular health, reduces the risk of adverse outcomes in cardiovascular diseases, and may protect against cognitive decline.
- Potential for Broad Application: The findings on BDNF’s regulatory mechanisms open potential for broader applications in platelet-based regenerative therapies, particularly in treating cardiovascular and neurodegenerative diseases.
