What is the Origin of Neurotrophic Flow?

This term is derived from neuroscience, combining "neurotrophic," pertaining to the nourishment and growth of nervous tissue, with "flow," suggesting a dynamic, circulating system. It conceptually represents the sustained biological support system for the brain. The most well-known example is Brain-Derived Neurotrophic Factor (BDNF).

What is the Mechanism of Neurotrophic Flow?

Neurotrophic factors are synthesized by neurons and glial cells and released locally, acting in a paracrine or autocrine fashion. The flow is maintained by both anterograde and retrograde axonal transport mechanisms, ensuring that factors reach their target sites. Physical exercise and specific hormonal signals, such as IGF-1 and certain sex steroids, are known to stimulate the production and enhance the systemic distribution of these vital neurotrophic factors.

Neurotrophic Flow

Meaning

Neurotrophic Flow is the continuous and regulated transport and availability of neurotrophic factors—proteins that support the survival, differentiation, and function of neurons—throughout the central and peripheral nervous systems. A healthy neurotrophic flow is essential for maintaining synaptic plasticity, supporting neuronal repair, and facilitating the adaptive response to cognitive and physical stimuli. Diminished flow is often associated with age-related cognitive decline.
