Can coffee improve memory?
Findings suggest the efficacy of Trigonelline derived from coffee in preventing and improving age-related spatial learning memory impairment
Following oral administration of TG to SAMP8 mice for 30 days, the Morris water maze test indicated a significant improvement in spatial learning and memory performance compared with SAMP8 mice that did not receive TG. Next, the researchers performed whole-genome transcriptomic analysis of the hippocampus to explore the underlying molecular mechanisms. They found that signaling pathways related to nervous system development, mitochondrial function, ATP synthesis, inflammation, autophagy, and neurotransmitter release were significantly modulated in the TG group. Furthermore, the research team found that TG suppressed neuroinflammation by negatively regulating signaling factor Traf6-mediated activation of the transcription factor NF-κB. Additionally, quantitative protein analysis confirmed that the levels of inflammatory cytokines TNF-α and IL-6 were significantly decreased and the levels of neurotransmitters dopamine, noradrenaline, and serotonin were significantly increased in the hippocampus. These findings suggest the efficacy of TG in preventing and improving age-related spatial learning memory impairment.
