Full Name: Cortagen (Cerebral Cortex Targeted Bioregulatory Tetrapeptide)
Core Mechanism of Action
Cortagen penetrates the nucleus of neurons and glial cells, remodels chromatin architecture, and reactivates functional genes silenced by cellular aging:
Decondense compact heterochromatin, restore transcriptional accessibility of age-suppressed neural genes;
-
- Upregulate expression of neurotrophic factors including BDNF, NGF and NT-3, boost neuronal protein synthesis and axonal regeneration;
- Balance excitatory/inhibitory neurotransmitter pathways (glutamate & GABA) to stabilize cortical neural electrical activity;
- Activate intracellular antioxidant enzymes to mitigate neuronal oxidative damage and lipid peroxidation;
- Suppress excessive microglial activation and pro-inflammatory cytokines to relieve neuroinflammation;
- Regulate lymphocyte gene expression to coordinate central nervous and peripheral immune functions;
- Accelerate myelin sheath repair of damaged nerve fibers and restore neural signal conduction efficiency.
