In vivo Neuroprotective Activity of Epopeptide AB Against Ischemic Damage
Abstract
Erythropoietin (Epo) is a hematopoietic factor, which stimulates proliferation and differentiation of erythroid precursor cells. Epo also functions as a neuroprotective factor and protects neurons from ischemic damage. Recently a 17-mer peptide sequence (Epopeptide AB) in Epo (AEHCSLNENITVPDTKV) with a neuroprotective function was reported. In this study, we showed in vivo evidence that Epopeptide AB protected neurons from ischemic damage at similar dose compared to Epo. Epopeptide AB could not stimulate the proliferation of Epo-dependent growing murine myeloid Ep-FDC-P2 cells and also did not compete the proliferative function of Epo on these cells. Together with these results, Epopeptide AB did not transduce signals through direct binding to the known Epo receptor on hematopoietic cells but has neuroprotective activity against ischemia.
