Polyphenols show promise for neurodegenerative diseases by reducing oxidative stress and preventing protein aggregation. Their chelating and gut-brain axis effects offer new therapeutic avenues for brain disorders.
Area of Science:
- Neuroscience
- Pharmacology
- Biochemistry
Background:
- The brain's complexity and neuronal function are critical for overall health.
- Neurodegenerative disorders are increasing, with limited therapeutic options.
- Plant-derived polyphenols possess diverse biological activities relevant to CNS health.
Purpose of the Study:
- To review the role of polyphenols in human healthcare, focusing on neuroprotection.
- To highlight polyphenol mechanisms against neurodegenerative pathologies.
- To explore polyphenol interactions with metal ions and the gut microbiota.
Main Methods:
- Literature review of studies on polyphenols and neurodegenerative diseases.
- Analysis of antioxidant, anti-acetylcholinesterase, and anti-amyloidogenic activities.
- Discussion of metal chelation and gut-brain axis modulation by polyphenols.
Main Results:
- Polyphenols exhibit antioxidant properties, counteracting reactive oxygen species in neurodegenerative conditions.
- They may act as acetylcholinesterase inhibitors and prevent amyloid-beta aggregation and tau hyperphosphorylation in Alzheimer's disease.
- Polyphenols function as natural chelators for metal ions (Cu, Zn, Fe) and influence the gut microbiota.
Conclusions:
- Polyphenols offer a promising natural strategy for preventing neuronal loss and treating central nervous system disorders.
- Their multifaceted actions, including antioxidant, anti-aggregation, metal chelation, and microbiota modulation, present novel therapeutic opportunities.
- Further research into polyphenols could lead to innovative treatments for complex neurological diseases.
