Developing effective treatments for neurodegenerative diseases like Parkinson's disease (PD) remains challenging. This review explores novel delivery systems for growth factors, focusing on ex vivo gene therapy and biomaterial-aided delivery for potential neuroprotection.
Area of Science:
- Neuroscience
- Biomedical Engineering
- Drug Delivery Systems
Background:
- No cure or preventative treatment exists for neurodegenerative diseases like Parkinson's disease (PD).
- Growth factors offer a promising therapeutic strategy for neuroprotection and neurorestoration in PD by supporting neuron survival.
- Protein-based growth factors face significant delivery challenges, including limited brain penetration and precise targeting of affected areas.
Purpose of the Study:
- To review alternative delivery systems for growth factors in treating neurodegenerative conditions.
- To highlight the potential of ex vivo gene therapy and biomaterial-aided delivery systems.
- To provide perspectives on the clinical development and translation of these novel delivery methods.
Main Methods:
- Review of existing literature on growth factor delivery systems for neurodegenerative diseases.
- Focus on ex vivo gene therapy approaches.
- Examination of biomaterial-aided protein and gene delivery strategies.
Main Results:
- Direct infusion and in vivo gene therapy are current clinical approaches for growth factor delivery in PD.
- Alternative methods like ex vivo gene therapy and biomaterial-aided delivery show significant potential.
- These alternative systems aim to overcome the limitations of traditional growth factor administration.
Conclusions:
- Novel delivery systems are crucial for advancing neurotrophin-based therapies for neurodegenerative diseases.
- Ex vivo gene therapy and biomaterial-aided delivery represent promising avenues for future clinical translation.
- Further research and development are needed to optimize these systems for effective neuroprotection and neurorestoration.
