β-Lactolin Reduces Age-Related Inflammation and Cognitive Decline

Area of Science:

• Neuroscience
• Gerontology
• Nutritional Science

Background:

• Global aging populations necessitate strategies for age-related cognitive decline and dementia.
• Dairy consumption is linked to reduced dementia risk in the elderly.
• Previous studies showed beta-lactolin improves cognitive function in older adults.

Purpose of the Study:

• To investigate the long-term effects of beta-lactolin on aging-related cognitive decline.
• To determine if beta-lactolin can prevent neural inflammation and memory impairment in aged mice.

Main Methods:

• Aged mice (20 months) were fed beta-lactolin for 3 months.
• Cognitive function was assessed using the novel object recognition test.
• Neural inflammation markers (microglia, cytokines) and hippocampal atrophy were analyzed.

Main Results:

• Beta-lactolin consumption alleviated memory impairment and normalized activity cycles in aged mice.
• It reduced activated microglia, pro-inflammatory cytokines, and hippocampal atrophy.
• Beta-lactolin also decreased cytochrome c levels in the hippocampus and cortex.

Conclusions:

• Beta-lactolin consumption prevents neural inflammation associated with aging.
• It effectively alleviates age-related cognitive decline and memory impairment.
• Beta-lactolin shows potential as a therapeutic intervention for cognitive aging.
