PSD-95 has been identified as a critical target for stroke therapy due to its role in neuroprotection and its interaction with NMDARs. Peptides such as AVLX-144 have shown efficacy in pre-clinical studies, indicating the potential of PSD-95 as a therapeutic target.
PSD-95, a scaffolding protein located in the postsynaptic density of neurons, plays a crucial role in the regulation of synaptic signaling and plasticity. By interacting with NMDA receptors, PSD-95 influences excitatory neurotransmission, which is essential for processes related to learning and memory.
Research has highlighted the contribution of PSD-95 to neuroprotection through the stabilization of NMDAR complexes and the promotion of cell survival pathways. The development of peptides that target the PDZ domains of PSD-95, such as AVLX-144, has exhibited promising results in mitigating excitotoxicity and reducing infarct size in experimental stroke models.
Neuroprotective peptides, whether of natural or synthetic origin, are currently under extensive investigation for their efficacy in the treatment of strokes by research teams such as the one affiliated with Henry Ford Hospital.
These peptides have demonstrated potential in improving the survival of brain cells and reducing inflammation in the brain post-stroke. By modulating excitotoxicity and oxidative stress, they present promising treatment options for various neurological disorders. The development of synthetic iterations of these peptides aims to enhance their stability and bioavailability, opening up new avenues for therapeutic interventions. The research team from Henry Ford Hospital is focused on elucidating the mechanisms underlying the neuroprotective properties of these peptides, with preliminary results suggesting the possibility of innovative strategies for intervening in stroke cases.

The mechanism of action of Vespakinin-M involves its interaction with the B2R receptor, resulting in decreased neuroinflammation in individuals who have experienced a stroke.
When Vespakinin-M binds to the B2R receptor, it triggers a series of signaling pathways that regulate the inflammatory response in the central nervous system. By targeting specific pathways related to neuroinflammation, Vespakinin-M helps to reduce the production of pro-inflammatory mediators and encourages the release of anti-inflammatory agents. This dual mechanism of action, which involves inhibiting inflammation and enhancing the body’s natural anti-inflammatory processes, contributes to the overall decrease in neuroinflammation observed in stroke patients undergoing Vespakinin-M therapy.
The efficient ability of Vespakinin-M to penetrate the blood-brain barrier enables it to deliver therapeutic effects directly to the site of injury, thereby enhancing its effectiveness in combating neuroinflammation.
Research conducted on mice with stroke has demonstrated that Vespakinin-M plays a significant role in reducing neurological impairment and facilitating recovery.
In a particular study, mice treated with Vespakinin-M exhibited enhanced motor functionality in contrast to the control group, thereby indicating the therapeutic efficacy of this compound. Researchers also noted a reduction in brain inflammation among the treated mice, suggesting a potential mechanism by which Vespakinin-M may elicit its neuroprotective properties.
These results underscore the promising prospect of Vespakinin-M as a viable therapeutic intervention for enhancing outcomes in stroke patients.
The research conducted on the Vespakinin-M peptide has unveiled its diverse array of advantages in stroke rehabilitation, encompassing brain protection and the preservation of blood-brain barrier (BBB) integrity.
