‘Acetaldehyde‐enkephalins’: elucidation of the structure of the acetaldehyde adducts of methionine‐enkephalin and leucine‐enkephalin [PDF]

open access: yesFEBS Letters, 1980
The two major endogenous opioid pentapeptides, methionine-enkephalin and leucine-enkephalin [ 1,2] rapidly react with acetaldehyde, under very mild conditions, to give an ‘acetaldehyde-enkephalin’ adduct, referred to as ‘acetaldehyde-enkephalin [Met’] and ‘acetaldehyde-enkephalin [Leu”], respectively 231.

Opioidergic pathways and kisspeptin in the regulation of female reproduction in mammals

open access: yesFrontiers in Neuroscience, 2022
Endogenous opioid peptides have attracted attention as critical neuropeptides in the central mechanism regulating female reproduction ever since the discovery that arcuate dynorphin neurons that coexpress kisspeptin and neurokinin B (NKB), which are also

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

Characteristic Temperatures of Folding of a Small Peptide [PDF]

open access: yes, 1997
We perform a generalized-ensemble simulation of a small peptide taking the interactions among all atoms into account. From this simulation we obtain thermodynamic quantities over a wide range of temperatures.

The Enhancing Effects of Peptidase Inhibitors on the Antinociceptive Action of [Met5]Enkephalin-Arg6-Phe7 in Rats

open access: yesJournal of Pharmacological Sciences, 2007
Previous in vitro studies have shown that the degradation of [Met5]enkephalin-Arg6-Phe7 during incubation with cerebral membrane preparations is largely prevented by a mixture of three peptidase inhibitors: amastatin, captopril, and phosphoramidon.

Endogenous Opioids in Crohn’s Disease

open access: yesBiomedicines, 2023
Caring for patients with Crohn’s disease (CD) is a serious challenge in modern medicine. The increasing incidence of CD among adolescents and the severe course of the disease create the need for new methods of diagnosis and therapy.

Responses of substantia gelatinosa neurons to putative neurotransmitters in an in vitro preparation of the adult rat spinal cord [PDF]

open access: yes, 1983
Extracellular recordings were performed from neurons of the substantia gelatinosa (SG) in an in vitro preparation obtained from the spinal cord of adult rats. About 40% of neurons were spontaneously active.

Enkephalins in hematopoiesis

open access: yesBiomedicine & Pharmacotherapy, 1997
Recent data support the view that neuropeptide mediators, in particular opioid peptides, participate in the control of hematopoiesis. The main arguments are: neuropeptides modulate the functions of lymphoid cells, macrophages and mature granulocytes; they control cell proliferation and differentiation in many tissues, particularly during embryogenesis;

Proenkephalin Derived Peptides Are Involved in the Modulation of Mitochondrial Respiratory Control During Epileptogenesis

open access: yesFrontiers in Molecular Neuroscience, 2018
Epilepsies are a group of common neurological diseases exerting a strong burden on patients and society, often lacking clear etiology and effective therapeutical strategies.
