The invention belongs to the technical field of novel application of
nattokinase, and provides application of
nattokinase in preparation of a
medicine for preventing and / or treating Parkinson's
disease. According to the invention, an
MPTP / MPP + induced Parkinson's
disease (PD) in-vivo and in-vitro model is established, and a
neuroprotection mechanism of
nattokinase is disclosed by adopting a systematic experiment method. Results show that the nattokinase can significantly improve
dyskinesia and intestinal dysfunction of
MPTP-induced PD mice; the damage of
dopaminergic neurons of the middle brain is effectively relieved, and the density of
tyrosine hydroxylase positive neurons is maintained; the expression of TLR4 and NLRP3
inflammasome pathways and related proinflammatory cytokines is inhibited, and the neuroinflammatory response is relieved; pINK1 / Parkin expression is up-regulated, mitochondrial
autophagy is activated, and damaged neurons are cleared. Direct association between nattokinase and Parkinson's
disease prevention and treatment is established for the first time, an innovative solution is provided for developing a novel anti-Parkinson's disease
medicine with dual effects of
motor function improvement and
neuroprotection, and the application has important development value in the field of treatment of neurodegenerative diseases.
