Enkephalins: Endogenous Analgesics with an Emerging Role in Stress Resilience
Neural Plasticity, 2017 Psychological stress is a state of mental or emotional strain or tension that results from adverse or demanding circumstances. Chronic stress is well known to induce anxiety disorders and major depression; it is also considered a risk factor for ...

Frontiers in Neural Circuits, 2022 The olfactory tubercle (OT) is a striatal region that receives olfactory inputs. mRNAs of prodynorphin (Pdyn) and preproenkephalin (Penk), precursors of dynorphins and enkephalins, respectively, are strongly expressed in the striatum. Both produce opioid

Exposure to exogenous enkephalins disrupts reproductive development in the Eastern lubber grasshopper, Romalea microptera (Insecta: Orthoptera). [PDF]
PLoS ONE, 2012 Enkephalins play a major role in reproductive physiology in crustaceans; however their role in reproductive development in insects is largely unknown. We investigated the effect of exposure to exogenous leucine-enkephalin (Leu-Enk), methionine-enkephalin

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

The effect of ethanol consumption on the carboxypeptidase E activity on different age rats posterity
Известия высших учебных заведений. Поволжский регион: Естественные науки, 2022 Background. The consumption of ethanol by dams strongly effects the offspring’s body, its health both at birth and throughout life. This effect has a particularly strong effect on the functioning of various regulatory systems, in particular ...

Journal of Neuroinflammation, 2022 Background Inflammatory visceral pain is endogenously controlled by enkephalins locally released by mucosal CD4+ T lymphocytes in mice. The present study aimed at identifying opioid receptor(s) expressed on nociceptive sensory nerves involved in this ...

Biomedicine & 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;

Acetaldehyde‐enkephalins: pronounced changes in the opiate activity of methionine‐enkephalin and leucine‐enkephalin on reaction with acetaldehyde [PDF]
FEBS Letters, 1980 We have shown that the two major endogenous opioid peptides, methionine-enkephalin and leucineenkephalin [ 1,2] (enkephalin [Met’] and enkephalin[Leu’]) rapidly react with acetaldehyde in aqueous buffers to give a stable ‘acetaldehyde-enkephalin’ adduct, referred to as ‘acetaldehyde-enkephalin[Met’]’ and ‘acetaldehyde-enkephalin [Leu’]‘, respectively ...
