Semax

Semax is a synthetic seven-amino-acid peptide based on part of ACTH. Researchers study it in brain science because it has been linked to growth and repair signals, gene activity, stress response, and brain plasticity. One well-known area of study is BDNF, a protein that helps support nerve cells and learning-related changes in the brain. Research on Semax has looked at learning, memory, brain injury models, oxidative stress, inflammation, and how nerve cells respond to stress. This makes Semax especially interesting for research on how short peptide signals may affect the brain's ability to adapt and recover.
