Abstract
Parkinson's disease (PD) is defined as a progressive neurodegenerative disease in middle-aged and elderly people. The therapeutic effect of ω-3 PUFAs in several neurodegenerative diseases has been well recognized. Nevertheless, whether nutrition supplementing ω-3 PUFAs exerts a neuroprotective role in PD remains elusive. Bioinformatics revealed 2D chemical structural formula of three components. Mice received indicated treatment with saline, MPTP or ω-3 PUFAs according to grouping. Behavioral function of mice was measured through motor tests such as rearing, akinesia, and rotarod tests. OFT test measured anxiety-like behaviors of mice. Western blotting and TUNEL staining measured dopaminergic fibers and neurons of mice. Western blotting measured inflammation and apoptosis-related protein levels in mouse tissue. FACS measured iTreg cell proportion in colon and brain tissues of mice. ω-3 PUFAs repaired MPTP-stimulated motor function damage in PD mice. ω-3 PUFAs mitigated MPTP-stimulated comorbid anxiety in PD mice. ω-3 PUFAs relieved MPTP-stimulated deficits of dopaminergic fibers and neurons in PD mice. ω-3 PUFAs repressed MPTP-stimulated inflammation and apoptosis pathway activation in PD mice. ω-3 PUFAs repaired MPTP-stimulated immune function damage in PD mice. ω-3 PUFAs exert a protective role in PD mice through alleviating motor function impairment and neuroinflammation by increasing intestinal inducible Treg cells, which may provide a new direction for seeking targeted therapy plans for PD in humans.
