Lactoferrin improves scopolamine-induced memory impairment in mice

Area of Science:

• Neuroscience
• Pharmacology
• Nutritional Science

Background:

• Global population aging is increasing cognitive decline and dementia prevalence.
• This poses significant healthcare and socioeconomic challenges.
• Identifying effective interventions for cognitive impairment is crucial.

Purpose of the Study:

• To investigate the effects of lactoferrin on scopolamine-induced memory impairment in mice.
• To explore the underlying molecular mechanisms of lactoferrin's action in the hippocampus.

Main Methods:

• Utilized the Barnes maze test and novel object recognition assay to assess cognitive function in ddY mice.
• Administered scopolamine to induce memory deficits and lactoferrin as a potential therapeutic agent.
• Analyzed hippocampal gene expression of inflammatory, oxidative stress, and apoptosis markers via RT-qPCR.

Main Results:

• Scopolamine significantly impaired spatial and object recognition memory.
• Lactoferrin administration markedly improved these cognitive deficits, comparable to donepezil.
• Lactoferrin attenuated scopolamine-induced increases in Tnf, Nos2, and Casp3 gene expression.

Conclusions:

• Lactoferrin effectively ameliorated scopolamine-induced memory impairment in mice.
• The protective effects are potentially mediated by the suppression of inflammation, oxidative stress, and neuronal apoptosis.
• Lactoferrin shows promise as a functional food component for preventing cognitive decline.
