VEGF mimetic peptides:potential applications in central nervous system therapeutics

VEGF is expressed in central nervous system and its expression increases in hypoxia and in inflammatory brain disorders. A wealth of data suggests that VEGF may exert neuroprotective activities and promote neuroregeneration in disease status. Moreover, the risk of developing certain neurological disorders may be dependent on dysfunction in the VEGF system. Therefore, a strong rationale does exist to suggest that VEGF-based therapeutics could be implemented in conditions such as stroke or amyotrophic lateral sclerosis and experimental data supporting this hypothesis have been obtained. However, the unfavorable pharmacokinetic profile of this growth factor, and concerns on its safety have limited the development of VEGF as a therapeutic tool for neurological disorders. In this review, we discuss why a new class of VEGF-mimic peptides holds promises to become a safer, cheaper and more easily manageable tool for central nervous system therapeutics.
