New perspectives on TREK-1 and PE 22-28 for mood

Posted by optimizer_jenna in Research & News - 42 points, 2 comments.

I have been reading more about the TREK-1 potassium channel and its role in neuroplasticity. I found this page on PE 22-28 /peptides/pe-22-28 and it is actually quite interesting that it might work faster than SSRIs because it targets synaptogenesis directly.

Tbh I am still very skeptical since most of this is preclinical. As someone who likes citations, it is hard to get excited when there is no human data yet. However, the idea of rapid neurogenesis is promising for longevity and brain health. I have looked into other nootropics before, but this mechanism seems DIFFERENT from the usual stuff.

I wonder if the short half life makes it less practical for real use or if that is actually a safety benefit. For me, the risk of unknown human safety is the BIGGEST hurdle.

Does anyone here follow the spadin research or have an opinion on whether TREK-1 inhibition is actually a viable path for mood and cognition in humans? I would be grateful for any papers or leads you can share. Thanks!

  • scott778: Been reading about TREK-1 and PE 22-28 myself. The spadin peptide angle is definitely different from the usual serotonin or dopamine targets most nootropics hit. That alone makes it worth a look, even if the human data is still thin. The half-life question is practical too. Shorter half-lives mean more frequent dosing, which can affect compliance, but also means the compound clears faster if something goes wrong. I've followed a bit of the spadin literature indirectly. Most of the neurogenesis
  • optimizer_jenna: Thank you for the reply. I agree that the faster clearance could be a safety benefit, but the idea of more frequent dosing sounds like a hassle tbh. Since most of the spadin literature is still animal models, it makes me wonder if the effect is actually transferable to humans. Do you think there are any specific markers we could track to see if it is actually working, or is it just waiting for a real study?
