Immunocytochemical evidence for the presence of Met-enkephalin and Leu-enkephalin in distinct neurons in the brain of the elasmobranch fish Scyliorhinus canicula. [PDF]

open access: yes, 1994
Immunohistochemical methods have been used to investigate the distribution of various opioid peptides derived from mammalian proenkephalin in the central nervous system of Scyliorhinus canicula.

CNS Active O-Linked Glycopeptides that Penetrate the BBB

open access: yesFrontiers in Chemistry, 2015
Naturally occurring glycopeptides and glycoproteins play important roles in biological processes. Glycosylation is one of the most common post-translational modifications in vivo.

Mapping the Substrate Specificity Landscape of PAD2 and PAD4 Enzymes

open access: yesChemBioChem, Volume 27, Issue 11, 15 June 2026.
Protein citrullination, driven by peptidyl arginine deiminases (PAD2, PAD4), is linked to multiple diseases. Using a combinatorial peptide library and advanced mass spectrometry, we reveal distinct substrate selectivity profiles of PAD2 and PAD4. While PAD2 broadly citrullinates arginine‐containing peptides, PAD4 is highly sequence‐restricted, with ...

Interaction of enkephalin and caerulein on guinea pig small intestine [PDF]

open access: yes, 1983
This is a report on the effect of caerulein and methionine-enkephalin interaction on mechanical contraction and acetylcholine release in vitro. The ability of enkephalin to relax caerulein-induced contractions and the manner in which the caerulein dose ...

UHPLC–MS based metabolomics study of the ErZhi formula on skeletal muscle against osteosarcopenia focusing on energy metabolism

open access: yesAnimal Models and Experimental Medicine, Volume 9, Issue 6, Page 1235-1247, June 2026.
ErZhi formula (EZF) is composed of Ligustri Lucidi Fructus (LLF) and Ecliptae herba (EH). Ovariectomized (OVX) and sham rats received 12‐week intragastric treatment with EZF, alendronate, and vehicle saline. Gastrocnemius tissues were harvested to systematically evaluate pharmacodynamic changes in skeletal muscle morphology, mitochondrial ...

Cardiac synthesis, processing, and coronary release of enkephalin-related peptides [PDF]

open access: yes, 2000
Although preproenkephalin mRNA is abundant in the heart, the myocardial synthesis and processing of proenkephalin is largely undefined. Isolated working rat hearts were perfused to determine the rate of myocardial proenkephalin synthesis, its processing ...

Sentience in cephalopod molluscs: an updated assessment

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1311-1333, June 2026.
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.

Advantages of Alkali Metal Adduct Formation in Cyclic Ion Mobility‐Mass Spectrometry of O‐Methylated Cyclodextrin Isomers—Separation and Crossring Fragmentation

open access: yesChemistry–Methods, Volume 6, Issue 6, June 2026.
Cyclic ion mobility–tandem mass spectrometry (cIM‐MS/MS) enables rapid differentiation of O‐methylated cyclodextrin (MeCD) regioisomers. The method separates 2,3‐ and 2,6‐DIMEB (heptakis‐2,3‐ and ‐2,6‐di‐O‐methyl‐β‐cyclodextrins) and identifies them via characteristic crossring fragmentation.

The lipolytic activity of met-enkephalin, leu-enkephalin, morphine, methadone and naloxone in human adipose tissue [PDF]

open access: yes, 1981
Met-enkephalin and Leu-enkephalin lipolytic activity in human omental adipose tissue is compared with that of morphine, methadone and naloxone. Met- and leu-enkephalin exhibited lipolytic action similar to that of morphine but unlike that of methadone ...
