Synthesis of ω-amino acid peptides related to leucine-enkephalin

open access: yes, 1981
Syntheses are described of four peptides with modified leucine-enkephalin sequences in which the native glycylglycyl segment is replaced by an ω-amino acid residue.

Rethinking Leucine Zipper : ribonuclease activity and structural dynamics of a ubiquitous oligomerization motif [PDF]

open access: yes, 2011
This dissertation focuses on structural, dynamic and catalytic properties of a Leucine Zipper (LZ) motif – a family of protein oligomerization domains which belong to the structural class of coiled coil proteins.

Electroacupuncture attenuates retinal ischemia/reperfusion injury by protecting the outer blood-retina barrier via enkephalins activate delta opioid receptor

open access: yesWorld Journal of Acupuncture - Moxibustion
Objectives: Retinal ischemia-reperfusion (RIR) injury results in irreversible visual impairments. The disruption of the outer blood-retinal barrier (OBRB) is a major ocular pathogenic process that RIR injury affects.

Gegen Qinlian decoction alleviates depression-like behavior by modulating the gut microenvironment in CUMS rats

open access: yesBMC Complementary Medicine and Therapies
Background Gegen Qinlian Decoction (GQD) is a classical traditional Chinese medicine (TCM) formula primarily utilized for treating gut disorders. GQD showed therapeutic effects on several diseases in clinical and animal studies by targeting gut microbes.

Immunohistochemical localization of tyrosine hydroxylase, substance P, neuropeptide-Y and leucine-enkephalin in developing human retinal amacrine cells

open access: yes, 1994
Prenatal changes in the neurotransmitter/neuromodulator profiles of tyrosine hydroxylase (for dopamine), substance P, neuropeptide Y, and leucine-enkephalin were studied in developing human retinal amacrine cells by the use of immunohistochemical ...

Design and self-assembly of a leucine-enkephalin analogue in different nanostructures: application of nanovesicles

open access: yes, 2012
An opioid (leucine-enkephalin) conformational analogue forms diverse nanostructures such as vesicles, tubes, and organogels through self-assembly. The nanovesicles encapsulate the natural hydrophobic drug curcumin and allow the controlled release through

Modulation of cholinergic neurotransmission in airways by enkephalin

open access: yes, 1985
We compared the effects of methionine enkephalin and leucine enkephalin on contractions of isolated canine tracheal smooth muscle strips induced by field electrical stimulation (ES) and exogenous acetylcholine (approximately 10(-5) M).

Substance P, bombesin, and leucine‐enkephalin immunoreactivities are restored in the frog tectum after optic nerve regeneration

open access: yes, 1995
Extensive regeneration of the optic nerve takes place in adult Amphibia. In this study, we have determined whether one aspect of retinotectal organisation, namely immunoreactive laminae in the retinorecipient layers of the optic tectum, is restored after

Photoinduced fragmentation of gas-phase protonated leucine-enkephalin peptide in the VUV range

open access: yes, 2015
In this article we report new results for action spectroscopy of protonated peptide Leucine enkephalin (YGGFL). By coupling a linear ion trap mass spectrometer with a vacuum ultraviolet (VUV) synchrotron radiation beamline, we investigate ...

Immunohistochemical localization of enkephalin-like substance in the central nervous system of the amphioxus [PDF]

open access: yes
The localization of enkephalin-like materials in the central nervous system of the amphioxus, Branchiostoma belcheri, was studied by immunohistochemical techniques, employing antisera raised in rabbit against synthetic methionine-enkephalin and leucine ...
