Research overview

DoseGear research brief

Cortagen is a Khavinson bioregulator tetrapeptide (AEDP) with primary effects on the brain and central nervous system. Developed at Russia's St. Petersburg Institute of Bioregulation and Gerontology, it regulates inflammatory responses in the nervous system, restores balance between pro- and anti-oxidative processes, and stimulates interleukin-2 expression. Research shows potential benefits for ischemic brain injury recovery, nerve regeneration, and reducing autoimmune reactions affecting the CNS.

Mechanism of action

Cortagen works through epigenetic regulation by penetrating cell nuclei and interacting with DNA to modulate gene expression. In the heart, it affects genes including Pass1, Hsc70, Bmp2, Wnt4, Eps15, and Eps15-rs. It powerfully regulates inflammatory responses in the nervous system, helping restore proper balance between oxidative and anti-oxidative processes. Cortagen stimulates IL-2 expression and helps regulate immune function, particularly by reducing autoimmune reactions.
