Lactoferrin ameliorates social isolation-induced cognitive decline by modulating mitochondrial function and...

Area of Science:

• Neuroscience
• Cell Biology
• Biochemistry

Background:

• Social isolation (SI) is linked to cognitive decline and dementia.
• Mitochondrial dysfunction and ferroptosis are potential mechanisms underlying SI's cognitive effects.

Purpose of the Study:

• To investigate the impact of SI-induced stress on cognitive function, mitochondrial function, and ferroptosis.
• To evaluate the therapeutic potential of lactoferrin (LF) in mitigating SI-induced cognitive dysfunction.

Main Methods:

• Male C57BL/6 mice were exposed to 8 weeks of social isolation.
• Lactoferrin intervention was administered to assess its effects on cognitive behavior and molecular markers.
• Assessed anxiety, depressive-like behavior, cognitive function, oxidative stress, mitochondrial dysfunction, and ferroptosis.

Main Results:

• SI induced anxiety, depressive-like behavior, cognitive decline, oxidative stress, mitochondrial dysfunction, and ferroptosis in mice.
• Lactoferrin treatment ameliorated SI-induced cognitive deficits and behavioral changes.
• LF administration reduced markers of oxidative stress, mitochondrial damage, and ferroptosis.

Conclusions:

• Lactoferrin effectively alleviates the negative cognitive and cellular consequences of social isolation.
• LF demonstrates therapeutic potential for cognitive dysfunction associated with social isolation.
• Findings highlight LF's role in mitigating molecular pathways like oxidative stress and ferroptosis.
