Chronic Intermittent Ethanol and Withdrawal Suppress Evoked and Spontaneous GABA Release Onto Distinct Populations of Basolateral Amygdala Principal Neurons

Addiction Biology, Volume 30, Issue 9, September 2025.
Rat basolateral amygdala principal neurons projecting to the nucleus accumbens (BLANAc) and bed nucleus of the stria terminalis (BLABNST) represent independent cell populations. In male BLANAc neurons only (left), CIE/WD decreases feedforward GABA release from lateral paracapsular interneurons.

Kinetics of chymotrypsin- and papain-catalysed synthesis of [leucine]enkephalin and [methionine]enkephalin [PDF]

Biochemical Journal, 1984
The proteinase-catalysed synthesis of [Leu]enkephalin and [Met]enkephalin was studied kinetically. N alpha-t-Butoxycarbonyl-amino acids and peptides or their ethyl esters served as acyl donors, and amino acid phenylhydrazides were used as acyl acceptors.

Opioid receptors in cardiovascular function

British Journal of Pharmacology, Volume 182, Issue 16, Page 3710-3725, August 2025.
Opioid receptors are G protein‐coupled receptors expressed by various cells in the heart, including myocytes and nerve fibres, and play a crucial role in modulating cardiac function. These receptors influence neural transmission, heart rate and myocyte contractility, offering cardioprotection.

The role of the endogenous opioid system in modulating orthodontic‐induced neurogenic inflammation of the dental pulp: A comprehensive review of the literature

International Endodontic Journal, Volume 58, Issue 8, Page 1126-1145, August 2025.
Abstract Background Orthodontic forces may lead to neurogenic inflammation in the dental pulp by triggering the release of somatosensory neuropeptides such as Substance P (SP), Calcitonin gene‐related peptide (CGRP) and Neurokinin A (NKA). In the vast majority of patients, acute symptoms are not triggered, probably due to the control of the neurogenic ...

Effects of Electroacupuncture at Different Time on Brain Methionine-Enkephalin Contents in Rats

针刺研究, 1995
The basic level of methionine-enkephalin (MEK) in rat medulla oblongata plus Pons was thehighest at 05: 00 o'clock and the lowest at 23: 00. In both the hypothalamus and the striatum at 05: 00 MEK levles were respectively higher.than those at 11: 00, 17:

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

World 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.
