Sex and Chronic Stress Alter the Distribution of Corticotropin‐Releasing Factor Receptor in Rat Hippocampus Following Oxycodone Conditioned Place Preference

Synapse, Volume 80, Issue 5, September 2026.
Chronic stress modifies the effect of oxycodone conditioned place preference (Oxy CPP) on corticotropin releasing factor 1 (CRFR1) subcellular distributions in hippocampal subregions. These stress‐ and oxycodone‐induced changes in CRFR1 density may influence sex differences in hippocampal learning and memory processes both at baseline and following Oxy

T-lymphocyte-derived enkephalins reduce Th1/Th17 colitis and associated pain in mice

, 2017
BACKGROUND:Endogenous opioids, including enkephalins, are fundamental regulators of pain. In inflammatory conditions, the local release of opioids by leukocytes at the inflammatory site inhibits nociceptor firing, thereby inducing analgesia. Accordingly,

Diagnostic value of serum proenkephalin as a biomarker of renal dysfunction in Iraqi patients with chronic kidney disease

Babcock University Medical Journal
Objective: To evaluate serum proenkephalin (PENK) levels in Iraqi patients with chronic kidney disease (CKD) and examine its diagnostic performance and correlation with conventional renal function markers.

Stability profiles of enkephalin and carbohydrate-derived enkephalins.

, 2014
A) Plasma stability assay: the concentration of compounds in plasma was determined at various time points using RP-HPLC on a C18 Vydac column, gradient of 20–35% (enkephalin) or 0–70% solvent B (glycosylated enkephalins) over 30 min.

Blood-brain transfer and antinociception of linear and cyclic N-methyl-guanidine and thiourea-enkephalins

, 2015
Enkephalins are active in regulation of nociception in the body and are key in development of new synthetic peptide analogs that target centrally located opioid receptors.

Fast-atom bombardment mass spectra of some pentapeptides related to natural enkephalins

, 1986
The mass spectral features of four diastereoisomeric pairs of peptides related to the enkephalins recorded under fast-atom bombardment conditions are presented and shown to provide evidence of molecular weight and amino acid content and sequence.

A novel and highly efficient purification procedure for native human dipeptidyl peptidase 3 from human blood cell lysate.

PLoS ONE, 2019
Dipeptidyl amino-peptidase 3 (DPP3) is an aminopeptidase involved in peptide degradation, including hormone peptides as angiotensin II and enkephalins. DPP3 plasma activity increases in septic patients and correlates with mortality risk.

Attenuation of the osmotic release of vasopressin by enkephalins in dogs

, 1989
To assess the possible role of circulating enkephalins in the osmotic release of vasopressin, Met5 (M-Enk)- or Leu5-enkephalin (L-Enk) dissolved in 0.9 or 10% NaCl was infused to either anesthetized or conscious dogs at a dose of 3.5 nM.kg-1.min-1 for ...

Enkephalins and endorphins as modifiers of the immune system: Present and future

, 1985
This paper summarizes the data related to the relations between enkephalins and endorphins and the immune system. It is shown that lymphocytes have surface receptors for endorphins and enkephalins.
