Growth Factor Therapies For Neurodegeneration is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.

Overview

Growth factors are proteins that regulate cell survival, proliferation, differentiation, and function. Neurotrophic growth factors are essential for neuronal survival and synaptic plasticity. Delivery of growth factors or their mimetics represents a promising therapeutic approach for neurodegenerative diseases. [@ngf]

Key Growth Factor Systems

Neurotrophins

• BDNF (Brain-Derived Neurotrophic Factor)
• NGF (Nerve Growth Factor)
• NT-3 (Neurotrophin-3)
• NT-4/5 (Neurotrophin-4/5)

Glial Cell Line-Derived Neurotrophic Factor Family

• GDNF (Glial Cell Line-Derived Neurotrophic Factor)
• Neurturin
• Artemin
• Persephin

Fibroblast Growth Factors

• FGF-2 (bFGF)
• FGF-20
• FGF-21

Other Growth Factors

• IGF-1 (Insulin-like Growth Factor-1)
• EGF (Epidermal Growth Factor)
• VEGF (Vascular Endothelial Growth Factor)

Molecular Mechanism

Receptor Signaling

Growth factors signal through: [@gdnf]

• PI3K/Akt
• MAPK/ERK
• PLCγ

Neuroprotective Effects

• Anti-apoptotic: Activation of survival pathways
• Synaptic plasticity: Enhanced spine formation, [LTP](/mechanisms/long-term-potentiation)
• Neurogenesis: Support of neural stem cells
• Axonal growth: Promotes regeneration
• Glial support: Protects oligodendrocytes
• Anti-inflammatory: Modulates [microglia](/entities/microglia)

Clinical Candidates

BDNF and BDNF Mimetics

GDNF Family

Other Growth Factors

Clinical Considerations

Challenges

Delivery Methods

• Intranasal: Bypasses BBB for some proteins
