Harnessing the Ocean's Power: Fucoidan as a Novel Neuroregenerative Agent

Area of Science:

• Marine biotechnology
• Neuroscience
• Pharmacology

Background:

• Neurological disorders involve neuronal loss and functional decline, lacking effective treatments.
• Fucoidan, from brown seaweed, is a sulfated polysaccharide with potential therapeutic applications.
• Preclinical evidence suggests fucoidan possesses neuroprotective and neuroregenerative properties.

Purpose of the Study:

• To review preclinical evidence on fucoidan's neuroprotective and neuroregenerative potential.
• To explore the mechanisms underlying fucoidan's therapeutic effects.
• To highlight the role of the microbiota-gut-brain axis in fucoidan's action.

Main Methods:

• Systematic review of preclinical studies on fucoidan in neurological disorder models.
• Analysis of fucoidan's anti-inflammatory, antioxidant, and anti-apoptotic activities.
• Investigation of fucoidan's interaction with the gut microbiota and the gut-brain axis.

Main Results:

• Fucoidan demonstrates significant anti-inflammatory effects by modulating glial cell activation.
• It exhibits potent antioxidant activity, neutralizing reactive oxygen species.
• Fucoidan directly inhibits apoptosis, protecting neurons from programmed cell death.
• Prebiotic effects on gut microbiota enhance systemic and central nervous system benefits.

Conclusions:

• Fucoidan is a multitarget natural compound with significant neuroprotective and neuroregenerative potential.
• Its efficacy is mediated through anti-inflammatory, antioxidant, and anti-apoptotic mechanisms.
• The microbiota-gut-brain axis plays a crucial role in fucoidan's therapeutic effects.
• Further research is needed to establish structure-activity relationships and clinical applications.
