A combination of Walnut Peptide and Casein Peptide substantially alleviates anxiety disorder symptoms and enhances memory by improving neurotransmitter function in mice.
The study investigated the effects of the combination of Walnut Peptide (WP) and Casein Peptide (CP) in mice exhibiting elevated anxiety levels by giving them these peptides through oral gavage administration. The researchers designed assessments to carefully examine changes in the subjects' anxiety and memory-related behaviors following this treatment. Besides monitoring behavior, they also scrutinized the levels of several neurotransmitters, such as Serotonin, gamma-aminobutyric acid, dopamine, and acetylcholine, to identify the biological mechanisms underlying the observed effects.
The mice treated with the WP + CP combination demonstrated significant improvement in behavioral tests related to anxiety and memory. The analysis also showed that the peptide combination resulted in restoring neurotransmitter dysfunction observed while examining neurotransmitter levels. The peptides had the additional effect of increasing the expression of brain-derived neurotrophic factor mRNA, suggesting a protective role against the neurological effects of anxiety. The research revealed strong correlations between the improvement in behavioral indicators, increased brain-derived neurotrophic factor, and neurotransmitter levels. The study concluded that the WP+CP combination might serve as an effective alternative therapy for anxiety disorders, implying potential usefulness as dietary supplements or inclusions in common foods.
