Fgf Signaling Pathway In Neurodegeneration plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
This mechanism describes the role of specific molecular pathways in neurodegenerative diseases. The following sections detail the signaling cascades, cellular effects, and disease relevance of this mechanism.
Fibroblast growth factor (FGF) signaling is crucial for neuronal development, survival, and plasticity. The FGF family includes 22 ligands (FGF1-FGF23) that signal through four FGF receptors (FGFR1-FGFR4). Dysregulated FGF signaling contributes to neurodegeneration, while FGF-based therapies show promise for neuroprotection.
FGF signaling is initiated by FGF ligand binding to FGFR with heparan sulfate co-factors, leading to receptor dimerization and autophosphorylation.
