Neurotrophic factor therapy aims to support and protect [neurons](/entities/neurons) through delivery of growth-promoting proteins that enhance neuronal survival, function, and regeneration. These factors play critical roles in neuronal development, synaptic plasticity, and neuroprotection. Therapeutic approaches include direct protein delivery, gene therapy, and small molecule mimics[@nagahara2024].
Overview

Key Neurotrophic Factors
Brain-Derived Neurotrophic Factor (BDNF)
Properties:
Member of the neurotrophin family
Binds to TrkB receptor with high affinity
Binds to p75^NTR with lower affinity
Critical for neuronal survival, differentiation, and synaptic plasticity[@korte2020]
Cell-penetrant variants: Modified proteins that enter cells
Targeted delivery: Antibody-conjugated factors
Combination therapy: Multiple factors + small molecules
Biomarkers for Patient Selection
Receptor expression levels
Disease stage
Genetic modifiers
Conclusion
Neurotrophic factor therapy represents a promising approach for neurodegenerative diseases by addressing the fundamental need for neuronal survival and regeneration. While delivery challenges remain significant, advances in gene therapy vectors, cell-based delivery, and small molecule mimetics offer hope for clinical translation. The key will be improving brain delivery and achieving sustained, localized expression of these protective factors.
