BackgroundParkinson's disease (PD) is a progressive neurodegenerative disorder linked to oxidative stress, mitochondrial dysfunction, and neuroinflammation. This study evaluates the neurofunctional and immunomodulatory effects of an aqueous extract combining cocoa seed husk and guarana powder (GuaCa). Eighteen extracts were characterized by flavonoid and polyphenol content, antioxidant activity, and genoprotective potential. The HCE3 extract, rich in catechins, quercetin, and epigallocatechin gallate, was selected for further analysis in three models: Eisenia fetida earthworms, SH-SY5Y neuron-like cells, and peripheral blood mononuclear cells (PBMCs) from PD patients.ResultsThe extracts showed antioxidant and genoprotective activity and contained flavonoid. No significant toxicity was observed in Eisenia fetida. In SH-SY5Y cells, GuaCa increased cell viability and brain-derived neurotrophic factor (BDNF) levels and reduced mitochondrial damage by lowering extracellular NDUSF7 (subunit of the NADH dehydrogenase (ubiquinone) complex) levels. In dPD-PBMCs cultures, GuaCa reduced pro-inflammatory cytokine IL-6 levels, indicating immunomodulatory effects.ConclusionGuaCa shows promise as a nutraceutical for managing neuroinflammation and mitochondrial dysfunction in PD. Further clinical studies are needed to confirm GuaCa extract efficacy and potential for neuroprotective dietary strategies.
