- Abstract
- Heat shock proteins (HSPs) are a highly conserved family of proteins that are induced in response to various environmental stressors including reactive oxygen species. HSP27 is a chaperone protein with the ability to increase cell survival in response to oxidative stress. Parkinsons disease (PD) is a neurodegenerative disorder characterized by loss of dopaminergic neurons. Although the mechanism of PD remains unclear, oxidative stress is known to be important in its pathogenesis. This study investigated the protective effects of PEP-1-HSP27 on neuronal damage induced by 1-methyl-4-phenyl pyridinium (MPP+) in SH-SY5Y cells and in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model. PEP-1-HSP27 rapidly entered the cells and protected them against MPP+-induced toxicity by inhibiting the reactive oxygen species levels and DNA fragmentation. Furthermore, transduced PEP-1-HSP27 prevented dopaminergic neuronal cell death in the substantia nigra of MPTP-induced PD mouse models. These results demonstrate that PEP-1-HSP27 provides a potential strategy for therapeutic delivery against various diseases and is a potential tool for the treatment of PD.
