The influence of experimental inflammation and axotomy on leucine enkephalin (leuENK) distribution in intramural nervous structures of the porcine descending colon

open access: yesBMC Veterinary Research, 2018
Background The enteric nervous system (ENS), located in the intestinal wall and characterized by considerable independence from the central nervous system, consists of millions of cells.

Methionine-enkephalin and leucine-enkephalin in human sympathoadrenal system and pheochromocytoma. [PDF]

open access: yesJournal of Clinical Investigation, 1982
To elucidate the physiological and pathophysiological significance of methionine- and leucine-enkephalin (Met-and Leu-enkephalin, respectively) in human sympathoadrenal system, the contents of these peptides in normal human sympathetic nervous system, adrenal medulla, and pheochromocytomas were determined by specific radioimmunoassays combined with ...

Metal-Binding Ability of Leu-Enkephalin, Related Glycoconjugates and Peptidomimetics

open access: yesCroatica Chemica Acta, 2015
Both the chemistry and consequences of the nonenzymatic reaction between reducing sugars and reactive amino groups of amino acids, peptides and proteins (known as the Maillard reaction), have received considerable attention in food and health science ...

Direct peptide bioconjugation/PEGylation at tyrosine with linear and branched polymeric diazonium salts [PDF]

open access: yes, 2012
Direct polymer conjugation at peptide tyrosine residues is described. In this study Tyr residues of both leucine enkephalin and salmon calcitonin (sCT) were targeted using appropriate diazonium salt-terminated linear monomethoxy poly(ethylene glycol)s ...

New analogues of leucine-methionine-enkephalin

open access: yesJournal of Biosciences, 1988
Nine analogues of the opioid pentapeptides leucine-/ methionine-enkephalinamide, involving replacement of amino acid at position 5 or amino acids at positions 2 and 5, have been synthesized by the solid phase method using mainly 9-fluorenylmethyloxycarbonyl amino acid trichlorophenyl esters in the presence of 1-hydroxybenzotriazole, the solid support ...

Pro-opiomelanocortin co-localizes with corticotropin-releasing factor in axon terminals of the noradrenergic nucleus locus coeruleus [PDF]

open access: yes, 2006
We previously demonstrated that the opioid peptide, enkephalin, and corticotropin-releasing factor (CRF) are occasionally co-localized in individual axon terminals but more frequently converge on common dendrites in the locus coeruleus (LC).

Serotoninergic, peptidergic and GABAergic innervation of the ventrolateral and dorsolateral motor nuclei in the cat S1/S2 segments: An immunofluorescence study [PDF]

open access: yes, 1994
Indirect single- and double-staining immunofluorescence techniques were used to study the serotoninergic, peptidergic and GABAergic innervation of the ventrolateral (Onuf's nucleus) and dorsolateral (innervating intrinsic foot sole muscles) nuclei ...

Acetaldehyde‐enkephalins: pronounced changes in the opiate activity of methionine‐enkephalin and leucine‐enkephalin on reaction with acetaldehyde [PDF]

open access: yesFEBS 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 ...
