Filbertone-Induced Nrf2 Activation Ameliorates Neuronal Damage via Increasing BDNF Expression

Area of Science:

• Neuroscience
• Molecular Biology
• Pharmacology

Background:

• Neurotrophic factors are crucial for neuronal survival.
• Brain-derived neurotrophic factor (BDNF) plays a role in Parkinson's Disease neurotoxicity.
• Neuroinflammation and Nrf2 pathway dysfunction are implicated in neurodegeneration.

Purpose of the Study:

• To investigate the neuroprotective potential of filbertone.
• To examine filbertone's effects on neurotrophic factors and the Nrf2 pathway.
• To evaluate filbertone as a therapeutic agent for neurodegenerative diseases.

Main Methods:

• Filbertone treatment in human neuroblastoma and mouse astrocyte/hypothalamus cell lines.
• Neurodegeneration models induced by high-fat diet (HFD), palmitic acid (PA), and MPTP/MPP+.
• Assessment of neurotrophic factor expression (BDNF, GDNF, NGF) and Nrf2 pathway activation.
• Evaluation of cell viability and neuroinflammation markers.
• Studies involving Nrf2-deficient mice.

Main Results:

• Filbertone significantly increased BDNF, GDNF, and NGF expression in neuronal and glial cells.
• Filbertone counteracted HFD-induced neuroinflammation and restored neurotrophic factors and Nrf2 activation.
• Filbertone protected against PA and MPTP/MPP+-induced neurotoxicity, enhancing cell viability and reducing inflammation.
• Neuroprotection was mediated by Nrf2 activation, leading to increased BDNF and heme oxygenase-1.
• Nrf2 deficiency abolished filbertone's neuroprotective effects in MPTP-treated mice.

Conclusions:

• Filbertone demonstrates significant neuroprotective properties.
• Filbertone enhances neuronal resilience by upregulating neurotrophic factors via the Nrf2 pathway.
• Filbertone represents a promising therapeutic candidate for neurodegenerative diseases like Parkinson's Disease.
