KYL peptide

KYL peptide, an antagonistic peptide, selectively targets EphA4 receptor. KYL peptide binds to the ligand-binding domain of EphA4, effectively alleviates Aβ-induced synaptic dysfunction and synaptic plasticity defects in AD mice. KYL peptide can promote nerve regeneration after injury and modulating immune responses.
