| Sumario: | Background: Ionotropic glutamate NMDA receptors are multi-subunit proteins with few selective pharmacological ligands and are tentatively implicated in MS and other neurodegenerative disorders. The present study was aimed at evaluating the antioxidant properties of Berberis vulgaris extract-loaded magnetite nanoparticles on the Grin1 gene expression in NMDA receptor in EAE Syrian mice.
Methods: EAE mice models were generated through active immunization with MBP and PTx and kept for days 9-14 until EAE signs appeared followed by administration of barberry extract loaded magnetic nanoparticles.
Results: Pure BE concentrations did not show recovery signs until days 7-9, but partial recovery in tail movement was seen on days 11 and 14, which was significant as compared to the control group in terms of improvement of the clinical scores. Meanwhile bare nanoparticles had neither disease recovery/progression properties nor EAE mice mortality as compared to controls, but 1 mg BE + Fe3O4 reduced EAE symptom severity and resulted in significant improvement of hind limb sensitivity to toe pinching and improved tail movements. Meanwhile 2 mg Be + Fe3O4 showed much better sensitivity to toe pinching and complete tail recovery. qRT-PCR analysis showed a significant decrease in relative Grin1 expression in female mice after treatment with 0.2 and 1 mg BE. However, a profound decrease in Grin1 expression was seen at 0.2, 1 and 2 mg BE + Fe3O4 treated groups in a dose-dependent manner.
Conclusion: The results indicated that Fe3O4+ BE could alleviate the EAE severity and progression |
