The targeted therapeutic strategy of enhancing the endogenous production or signaling of key regulatory peptides and proteins, such as Brain-Derived Neurotrophic Factor (BDNF), that precisely govern the excitability, plasticity, and ongoing development of neuronal circuits. Upregulation of these vital factors is essential for actively promoting neurogenesis, improving synaptic function, and significantly increasing the overall cognitive reserve. This is a vital, proactive mechanism for resisting and reversing age-related neurological decline and maintaining cognitive vitality.
Origin
This concept is scientifically derived from molecular neuroscience and pharmacology, focusing intently on the trophic (nourishing) support systems of the central nervous system. The clinical application in hormonal health acknowledges that many endogenous hormones, including estrogen and testosterone, are powerful, direct regulators of neurotrophic factor gene expression and subsequent protein synthesis.
Mechanism
Upregulation is primarily achieved by activating specific intracellular signaling pathways that lead to increased transcription of neurotrophic factor genes within both neurons and supporting glial cells. For instance, targeted physical activity or specific hormonal signals can potently activate the CREB pathway, a master regulator of neuroplasticity genes. The subsequent increase in factors like BDNF promotes the structural growth of new synapses and strengthens the functional efficacy of existing neural connections, thereby improving complex learning, memory, and mood regulation.
