Neuroanatomical distribution of the enkephalinergic and tachykininergic systems in the alpaca brainstem: an immunohistochemical study

open access: yesFolia Histochemica et Cytobiologica, 2021
INTRODUCTION: A recent study has shown a close neuroanatomical relationship between the enkephalinergic (methionine-enkephalin) and tachykininergic (substance P) systems in the alpaca diencephalon.

Actions of D-Ala2-D-Leu5-enkephalin and dynorphin A (1–17) on neocortical neurons in vitro [PDF]

open access: yes, 1984
Intracellular recordings were made from neocortical neurons in vitro. Application of D-Ala2-D-Leu5-enkephalin (DADL) by different methods produced a decrease in EPSP amplitude and in the amplitude of L-glutamate-induced depolarizations without changes in

Endogenous Opioid Levels Do Not Correlate With Itch Intensity and Therapeutic Interventions in Hepatic Pruritus

open access: yesFrontiers in Medicine, 2021
Background: Chronic pruritus affects up to 70% of patients with immune-mediated hepatobiliary disorders. Antagonists of the μ-opioid receptor (MOR) and agonists of the κ-opioid receptor (KOR) are used to treat hepatic itch, albeit with limited success ...

The folding funnel landscape for the peptide met-enkephalin [PDF]

open access: yesProteins: Structure, Function, and Genetics, 1999
We study the free energy landscape of the small peptide Met-enkephalin. Our data were obtained from a generalized-ensemble Monte Carlo simulation taking the interactions among all atoms into account. We show that the free energy landscape resembles that of a funnel, indicating that this peptide is a good folder.

Cytogenetic effects of combination of tridecactide and met-enkephalin on lymphocytes of patients with multiple sclerosis

open access: yesJournal of Health Sciences, 2015
Introduction: The met-enkephalin (1-5 Adrenorphin) and tridecactide (alpha-corticotropin 1-13) combination is used in the multiple sclerosis (MS) immuno-modulatory treatment.

Influence of Mutations of Conserved Arginines on Neuropeptide Binding in the DPP III Active Site

open access: yesMolecules, 2023
Dipeptidyl peptidase III (DPP III), a zinc exopeptidase, is involved in the final steps of intercellular protein degradation and has a marked affinity for opioid peptides such as enkephalins and endomorphins.

Nuclear‐Magnetic‐Resonance Study on Met‐enkephalin and Met‐enkephalin [PDF]

open access: yesEuropean Journal of Biochemistry, 1979
The 270‐MHz 1H and 68‐MHz 13C nuclear magnetic resonance spectra of Met‐enkephalin (Tyr‐Gly‐Gly‐Phe‐Met) and Met‐enkephalinamide are analyzed in a variety of solvents. For the dipolar form of Met‐enkephalin in (C2H3)2SO solution, significant concentration dependences are found of C‐α proton chemical shifts, indicating an aromatic ring‐current effect in

Opioid mediated activity and expression of mu and delta opioid receptors in isolated human term non-laboring myometrium

open access: yes, 2013
The existence of opioid receptors in mammalian myometrial tissue is now widely accepted. Previously enkephalin degrading enzymes have been shown to be elevated in pregnant rat uterus and a met-enkephalin analogue has been shown to alter spontaneous ...

Human hepatic met-enkephalin and delta opioid receptor-1 immunoreactivities in viral and autoimmune hepatitis

open access: yesAnnals of Hepatology, 2008
Endogenous opioids participate in growth regulation. Liver regeneration relates to growth. Thus, we explored the expression of methionine enkephalin and of the delta opioid receptor 1 immunoreactivities with a polyclonal rabbit antibody in deparaffinized

Perspectives on Endogenous Opioids in Birds

open access: yesFrontiers in Physiology, 2018
The present review summarizes the state of knowledge of endogenous opioids in birds. Endogenous opioid peptides acts in a neuromodulatory, hormonal and paracrine manner to mediate analgesic and other physiological functions.
