Skin-research peptides fall into signal, carrier, neurotransmitter and enzyme-inhibitor classes. Here is the reference for each.
Peptides used in dermal-research literature are grouped into four functional classes. Each class has established in-vitro endpoints used to compare lot performance.
| Class | Example | In-vitro endpoint |
|---|---|---|
| Signal | GHK, palmitoyl pentapeptide | Collagen I/III, elastin, fibronectin transcripts |
| Carrier | GHK-Cu | Copper delivery, SOD expression |
| Neurotransmitter | Acetyl hexapeptide-8 (Argireline) | SNARE complex modulation |
| Enzyme-inhibitor | Palmitoyl oligopeptide | MMP-1 down-modulation |
