People's experiences with neuropeptides

I am interested in seeing peoples experiences with neuropeptides such as Cerebrolysin, Semax, and Dihexa. Are these compounds the sort of "game changer" when it comes to neuroplasticity? I would imagine increasing bdnf by such a large magnitude would seem promising. I am in my mid 20s, so I'm in the final stretch of brain development. I would like anything of use. Thanks!

Tachykinin neuropeptides might promote agression, fear, paranoia when released due to chronic social isolation.

I was listening to Andrew Huberman's Huberman lab podcast and there was a short segment that got me. He stated that there are (might be in humans) specific neuropeptides that are released on perceived lack of social connections/interaction. That in turn causes paranoia, fear and agression among possible other effects.

I found this study that states that this experiment was done in flies and mice (to confirm mammals having this mechanism).

I cannot really give any extra information about this, except that I looked back on my behaviour in the past months or so. It feels like I am incredibly paranoid and fearful at times when I did not recently interact with people who are already close to me.

I have to add that I might also be depressed. Going on a holiday with my family did not really elevate my mood or lack of motivation. However I feel a bit less like I am being ripped off, unequally dealt with or socially abandoned by other people.

I concluded that it might be essential for ya'll folks to be already having interacted, especially with people who you bond with, BEFORE you try to do it to people that are more like strangers to you. Maybe that is what a Wingman could do to certain people.

People who fear going out of their house might also consider whether they had personal (not through internet) interactions with any friends or relatives they like recently.

Do neuropeptides get recycled back into the cell after they have been released?

I am writing a paper on neuropeptides and am wondering if they get recycled back into the brain after they have been released like neurotransmitters. If not, what happens to them? Do the neuropeptides just float around in the intercellular matrix?

In a recent study conducted in mice, researchers uncovered the neurobiological mechanisms of how exercise increases the brain's resilience to stress. Exercise elevates levels of galanin, a neuropeptide that influences mood, stress, and cognition. inverse.com/mind-body/braโ€ฆ

AMAZING NEUROPEPTIDE

AMAZING NEUROPEPTIDE

Neurodegenerative disorders (NDDs) are characterized by neuronal death in the brain. The mechanism of the neuronal death is too complicated to be fully understood, although in many NDDs, aging and neurotoxins are known risk factors. In the central and peripheral nervous system, vasoactive intestinal peptide (VIP), a 28-amino acid neuropeptide, is released to support neuronal survival in both physiological and pathological condition. VIP can inhibit the neurodegeneration induced by the loss of neurons. The indirect protection effect is mainly mediated by glial cells through the production of neurotrophic factor(s) and inhibition of proinflammatory mediators. By remolding the structure and improving the transfer efficiency of VIP, its nerve protective function could be further improved. Its neuroprotective action and efficacy in inhibiting a broad range of inflammatory responses make VIP or related peptides becoming a novel therapeutic method to NDDs. In this review, we aim to summarize the relationship between VIP and NDDs.

Has anybody tried Neuropeptide-S?

Thereโ€™s a product called Neuropeptide-S spray up on ReachGenius and itโ€™s been there for a year. Just wondering if anybody has any experience with the product or the nootropic itself.

It appears to stimulate dopaminergic neurotransmission in the medial prefrontal cortex, as well as many other benefits seen in that article. So take those studies how youโ€™d like, but iโ€™m just surprised that nobody has reported any experiences with a product from a fairly well known company. Any thoughts/experiences?

THE AMAZING NEUROPEPTIDE and cancer

THE AMAZING NEUROPEPTIDE and cancerโ€”โ€”โ€”

The VIP antagonist is a hybrid peptide consisting of a portion of VIP and a portion of neurotensin, designed to change the membrane permeability of the VIP portion. The hybrid antagonist displaced 80 to 90% of [125I]VIP binding to cell cultures from cerebral cortex, hippocampus or spinal cord.

https://pubmed.ncbi.nlm.nih.gov/1646331/

The most prevalent lung cancer, non-small cell lung cancer (NSCLC) has receptors for vasoactive intestinal peptide (VIP). Here the effects of a VIP antagonist (VIP-hyb) on NSCLC growth were investigated.

Maybe a little dumb question(about Neuropeptide S)

Hi,

so I've been researching different types of nootropics and research chemicals, and I've come across a substance by the the name of Neuropeptide S(human). What I'm curious is the (human) part. Does it mean that it's derived from human? If so, does anyone know how exactly? I'm just worried about ethcical implications here...

Thanks in advance.

The Conformational Equilibrium of the Neuropeptide Y2 Receptor in Bilayer Membranes

Structural transitions of crucial molecular switches of the activation of the human neuropeptide Y receptor type 2 are reported from the 13Cโ€tryptophan labeled molecule by solidโ€state NMR spectroscopy in lipid membranes. The molecule shows high structural dynamics in the apo and agonistโ€bound states, which is reduced by arrestin binding.

Abstract

Dynamic structural transitions within the sevenโ€transmembrane bundle represent the mechanism by which Gโ€proteinโ€coupled receptors convert an extracellular chemical signal into an intracellular biological function. Here, the conformational dynamics of the neuropeptide Y receptor type 2 (Y2R) during activation was investigated. The apo, full agonistโ€, and arrestinโ€bound states of Y2R were prepared by cellโ€free expression, functional refolding, and reconstitution into lipid membranes. To study conformational transitions between these states, all six tryptophans of Y2R were 13Cโ€labeled. NMRโ€signal assignment was achieved by dynamicโ€nuclearโ€polarization enhancement and the individual functional states of the receptor were characterized by monitoring 13Cโ€…NMR chemical shifts. Activation of Y2R is mediated by molecular switches involving the toggle switch residue Trp2816.48 of the highly conserved SWLP motif and Trp3277.55 adjacent to the NPxxY motif. Furthermore, a conformationally preserved โ€œcysteine lockโ€โ€Trp11623.50 was identified.
