Аннотация
AIM: This study investigated the neuroprotective effects of resveratrol (RVT)-loaded polysorbate 80 (PS80)-coated poly(lactide) nanoparticles in a mouse model of Parkinson's disease (PD), and compared these effects with those from bulk RVT.
METHODS: C57BL/6 mice received for 15 days RVT intraperitoneally (nanoparticulate or non-nanoparticulate), as well as single intranasal administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), a neurotoxin that damages dopaminergic neurons and induces PD-related symptoms.
RESULTS: MPTP induced significant impairments on olfactory discrimination and social recognition memory, as well as caused striatal oxidative stress and reduced the expression of tyrosine hydroxylase in striatum. RVT-loaded nanoparticles (but not bulk) displayed significant neuroprotection against MPTP-induced behavioral and neurochemical changes.
CONCLUSION: These results point to RVT-loaded poly(lactide)-nanoparticles coated with PS80 a promising nanomedical tool and adjuvant therapy for PD.
