The cellular communication pathway initiated by Brain-Derived Neurotrophic Factor (BDNF), a protein essential for the survival, differentiation, and plasticity of neurons. This signaling is critical for maintaining robust cognitive function, regulating mood, and ensuring overall neuronal health throughout the entire lifespan. Disruptions in this specific pathway are increasingly implicated in various neurodegenerative and psychiatric conditions.
Origin
The term combines the abbreviation BDNF, which stands for Brain-Derived Neurotrophic Factor, with signaling, referring to the cascade of molecular interactions that transmit a message from a cell’s exterior to its interior. BDNF was first isolated and characterized in the 1980s as a key member of the neurotrophin family of growth factors. Its discovery highlighted the brain’s remarkable capacity for structural adaptation and self-repair.
Mechanism
BDNF primarily exerts its crucial effects by binding to the high-affinity tropomyosin receptor kinase B (TrkB) receptor on neuronal surfaces. This binding triggers a cascade of intracellular events, including the activation of the MAPK, PI3K, and PLC-gamma signaling pathways. These complex downstream effects ultimately promote gene expression related to synaptogenesis, long-term potentiation, and neurogenesis, supporting the structural and functional integrity of the nervous system.
