Neuronal pathways in tendon healing and tendinopathy : update [PDF]

open access: yes, 2016
The regulatory mechanisms involved in tendon homeostasis and repair are not fully understood. Accumulating data, however, demonstrate that the nervous system, in addition to afferent (sensory) functions, through efferent neuronal pathways plays an active

RELEASE OF VASOPRESSIN BY ENKEPHALIN [PDF]

open access: yesBritish Journal of Pharmacology, 1978
Leu‐enkephalin, its stable analogue [D‐Ala2‐D‐Leu5]‐enkephalin and the C‐fragment of lipotropin (β endorphin) injected intravenously in the rat produced anti‐diuretic responses which were inhibited reversibly by naloxone. It was shown for Leu‐enkephalin that injection into the cerebral ventricles was at least ten times more effective than intravenous ...

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 ...

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.

Simultaneous mass spectrometry imaging of multiple neuropeptides in the brain and alterations induced by experimental parkinsonism and L-DOPA therapy

open access: yesNeurobiology of Disease, 2020
Neuropeptides are important signalling molecules in the brain and alterations in their expression levels have been linked to neurological disorders such as Parkinson's disease. It is challenging to map neuropeptide changes across and within brain regions

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.

Electroacupuncture attenuates retinal ischemia/reperfusion injury by protecting the outer blood-retina barrier via enkephalins activate delta opioid receptor

open access: yesWorld Journal of Acupuncture - Moxibustion
Objectives: Retinal ischemia-reperfusion (RIR) injury results in irreversible visual impairments. The disruption of the outer blood-retinal barrier (OBRB) is a major ocular pathogenic process that RIR injury affects.

Expression of the Antimicrobial Peptide Piscidin 1 and Neuropeptides in Fish Gill and Skin: A Potential Participation in Neuro-Immune Interaction

open access: yesMarine Drugs, 2022
Antimicrobial peptides (AMPs) are found widespread in nature and possess antimicrobial and immunomodulatory activities. Due to their multifunctional properties, these peptides are a focus of growing body of interest and have been characterized in several

White Adipose Tissue Browning and Cross Talk With Metabolic Diseases and Tumors: From Molecular Mechanisms to Clinical Translation

open access: yesMed Research, Volume 2, Issue 2, Page 280-308, June 2026.
White adipose tissue undergoes browning under endogenous and exogenous stimuli, primarily regulated by core molecules such as PRDM16 and UCP1. It exhibits a double‐edged sword effect in metabolic diseases and tumors: while mitigating metabolic disease impacts and suppressing early‐stage tumors through nutritional competition, it may accelerate cachexia

Peptide ligand recognition by G protein-coupled receptors [PDF]

open access: yes, 2015
Introduction: This study was conducted to investigate the effects of thyme extract in drinking water on immune response of broiler chickens. Methods: A total of 245-day-old broiler chicks were purchased and 20 chicks were bled for determination maternal ...
