Nerve Growth Factor Biodelivery: A Limiting Step in Moving Toward Extensive Clinical Application?

Area of Science:

• Neuroscience
• Biochemistry
• Pharmacology

Background:

• Nerve growth factor (NGF) is a key neurotrophin with significant biological effects on the central and peripheral nervous systems.
• NGF is recognized for its neuroprotective properties, making it a candidate for treating neurodegenerative conditions.

Purpose of the Study:

• To review the endogenous production of NGF in both healthy and pathological states.
• To examine conventional and biomaterial-assisted NGF delivery strategies.
• To clarify impediments hindering the clinical application of NGF.

Main Methods:

• Literature review of endogenous NGF production.
• Analysis of various NGF delivery systems, including biomaterial-assisted approaches.
• Discussion of challenges in NGF clinical application.

Main Results:

• NGF has demonstrated neuroprotective capabilities in various studies.
• Clinical application of NGF is limited by side effects and challenges in dosing and administration.
• Biomaterial-assisted delivery presents a potential strategy to improve NGF administration.

Conclusions:

• Understanding NGF's endogenous production is crucial for therapeutic development.
• Overcoming delivery and side effect challenges is key to unlocking NGF's clinical potential.
• Further research into optimized delivery strategies is necessary for effective NGF-based therapies.
