Photocaged Oxytocin and Vasopressin Probes to Decipher Neuropeptide Signalling With High Spatiotemporal Resolution

open access: yesAngewandte Chemie International Edition, EarlyView.
Novel and biocompatible photoactivatable oxytocin and vasopressin probes, utilising state‐of‐the‐art photocages, remain inactive in the dark. Light exposure facilitates rapid spatiotemporal receptor activation and phospholipase C (PLC)‐mediated downstream signalling. Figure created in https://BioRender.com.

Analgesia linked to Nav1.7 loss of function requires µ- and δ-opioid receptors [version 1; referees: 2 approved]

open access: yesWellcome Open Research, 2018
Background: Functional deletion of the Scn9a (sodium voltage-gated channel alpha subunit 9) gene encoding sodium channel Nav1.7 makes humans and mice pain-free. Opioid signalling contributes to this analgesic state.

Selank effects on morphine-induced analgesia in vivo experiments

open access: yesФармакокинетика и Фармакодинамика, 2022
Background. The endogenous opioid system is involved in neuroadaptation produced by exogenous opioids. Synthesized on the basis of the regulatory peptide tuftsin, the anxiolytic selank inhibits the activity of enkephalin-degrading enzymes, increasing the

The Evolution of Fangs, Venom, and Mimicry Systems in Blenny Fishes [PDF]

open access: yes, 2017
Venom systems have evolved on multiple occasions across the animal kingdom, and they can act as key adaptations to protect animals from predators. Consequently, venomous animals serve as models for a rich source of mimicry types, as non-venomous ...

Enkephalin-inactivating enzymes.

open access: yesFolia Pharmacologica Japonica, 1993
The inhibitory effects of opioid peptides such as [Met5]-enkephalin and [Met5]-enkephalin-Arg6 on the electrically-evoked contractions of guinea-pig ileum, mouse vas deferens and rat vas deferens were enhanced by aminopeptidase inhibitors such as amastatin and bestatin, a peptidyl dipeptidase A inhibitor like captopril, and endopeptidase-24.11 ...

Sentience in cephalopod molluscs: an updated assessment

open access: yesBiological Reviews, EarlyView.
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Double labelling immunohistochemical characterization of autonomic sympathetic neurons innervating the sow retractor clitoridis muscle [PDF]

open access: yes, 2008
Retrograde neuronal tracing and immunohistochemical methods were used to define the neurochemical content of sympathetic neurons projecting to the sow retractor clitoridis muscle (RCM). Differently from the other smooth muscles of genital organs, the RCM

Probing the Influence of Sulfur–Aromatic Interactions on the Electronic Structure of Gas‐Phase Peptides

open access: yesChemistry – A European Journal, EarlyView.
Just as fingerprints reveal identity, spectroscopic fingerprints reveal molecular secrets. In this article, we show parts of the unique fingerprint of the sulfur–aromatic interaction. By measuring how this force alters the electronic structure of gas‐phase peptides, we provide a fundamental understanding of interactions that give insights into the ...

A drug delivery strategy: binding enkephalin to asialoglycoprotein receptor by enzymatic galactosylation. [PDF]

open access: yesPLoS ONE, 2014
Glycosylation of biopharmaceuticals can mediate cell specific delivery by targeting carbohydrate receptors. Additionally, glycosylation can improve the physico-chemical (drug-like) properties of peptide based drug candidates.
