KYL peptide 

KYL peptide, an antagonistic peptide, selectively targets EphA4 receptor (IC₅₀:4.22 μM, Kd:1.3 μM). 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^[1][2][3].

KYL peptide blocks the extracellular ligand-binding domain of EphA4, abolishes the Aβ-stimulated EphA4 tyrosine phosphorylation^[2].
KYL peptide abolishes the Aβ-triggered reduction of dendritic spines in cultured hippocampal neurons^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
