Lactoferrin as a Candidate Multifunctional Therapeutic in Synucleinopathies

Area of Science:

• Neuroscience
• Biochemistry
• Pharmacology

Background:

• Lactoferrin (Lf) is a glycoprotein with known antimicrobial, anti-inflammatory, and iron-binding functions.
• Emerging research suggests Lf possesses neuroprotective properties, particularly relevant for neurodegenerative disorders like Parkinson's disease (PD).
• Alpha-synuclein (aSyn) aggregation is a key pathological feature in PD and other synucleinopathies, leading to neuronal damage.

Purpose of the Study:

• To review the mechanisms by which Lactoferrin (Lf) may counteract alpha-synuclein (aSyn) aggregation in synucleinopathies.
• To explore Lf's potential as a disease-modifying therapeutic agent for neurodegenerative conditions.
• To discuss innovative delivery strategies for enhancing Lf's clinical efficacy.

Main Methods:

• Literature review of existing studies on Lactoferrin (Lf) and alpha-synuclein (aSyn) aggregation.
• Analysis of Lf's biochemical properties, including iron chelation, antioxidant, and anti-inflammatory effects.
• Exploration of Lf's ability to cross the blood-brain barrier and influence the gut-brain axis.

Main Results:

• Lactoferrin (Lf) may inhibit aSyn aggregation through various mechanisms.
• Lf's iron-chelating, antioxidant, and anti-inflammatory actions contribute to its neuroprotective effects.
• Lf's capacity to traverse the blood-brain barrier and modulate the gut-brain axis supports its therapeutic potential.

Conclusions:

• Lactoferrin (Lf) presents a promising therapeutic candidate for synucleinopathies due to its multifaceted neuroprotective actions.
• Further research into Lf's mechanisms and optimized delivery is warranted for clinical development in neurodegenerative diseases.
• Lf offers a potential strategy to address the pathological cascade of aSyn aggregation and neuroinflammation.
