The organisation of spinoparabrachial neurons in the mouse [PDF]

open access: yes, 2015
The anterolateral tract (ALT), which originates from neurons in lamina I and the deep dorsal horn, represents a major ascending output through which nociceptive information is transmitted to brain areas involved in pain perception.

Synthetic Analogue of Leu-Enkephalin Prevents Endothelial Dysfunction in vitro

open access: yesОбщая реаниматология, 2018
The purpose of the study was to determine the efficacy of a synthetic leu-enkephalin stabilized analogue to prevent damage of endothelial cells monolayer in vitro caused by serum samples from septic shock patients.Materials and methods.

Rugged Metropolis Sampling with Simultaneous Updating of Two Dynamical Variables [PDF]

open access: yes, 2005
The Rugged Metropolis (RM) algorithm is a biased updating scheme, which aims at directly hitting the most likely configurations in a rugged free energy landscape. Details of the one-variable (RM$_1$) implementation of this algorithm are presented.

Delta Opioid Receptor Signaling Promotes Resilience to Stress Under the Repeated Social Defeat Paradigm in Mice

open access: yesFrontiers in Molecular Neuroscience, 2018
The adaptation to chronic stress is highly variable across individuals. Resilience to stress is a complex process recruiting various brain regions and neurotransmitter systems. The aim of this study was to investigate the involvement of endogenous opioid

Reconstructing the free-energy landscape of Met-enkephalin using dihedral Principal Component Analysis and Well-tempered Metadynamics

open access: yes, 2012
Well-Tempered Metadynamics (WTmetaD) is an efficient method to enhance the reconstruction of the free-energy surface of proteins. WTmetaD guarantees a faster convergence in the long time limit in comparison with the standard metadynamics.

Alterations in Cortical and Basal Ganglia Levels of Opioid Receptor Binding in a Rat Model of l-DOPA-Induced Dyskinesia

open access: yesNeurobiology of Disease, 2001
Opioid receptor-binding autoradiography was used as a way to map sites of altered opioid transmission in a rat model of l-DOPA-induced dyskinesia. Rats with unilateral 6-hydroxydopamine lesions of the nigrostriatal pathways sustained a 3-week treatment ...

Cocaine Reduces the Neuronal Population While Upregulating Dopamine D2-Receptor-Expressing Neurons in Brain Reward Regions: Sex-Effects

open access: yesFrontiers in Pharmacology, 2021
Addiction to cocaine is associated with dysfunction of the dopamine mesocortical system including impaired dopamine-2 receptor (D2r) signaling. However, the effects of chronic cocaine on neuronal adaptations in this system have not been systematically ...

Dopamine-D1 and δ-opioid receptors co-exist in rat striatal neurons [PDF]

open access: yes, 2006
Cocaine’s enhancement of dopaminergic neurotransmission in the mesolimbic pathway plays a critical role in the initial reinforcing properties of this drug. However, other neurotransmitter systems are also integral to the addiction process.

Striatal Neuropeptides Enhance Selection and Rejection of Sequential Actions

open access: yesFrontiers in Computational Neuroscience, 2017
The striatum is the primary input nucleus for the basal ganglia, and receives glutamatergic afferents from the cortex. Under the hypothesis that basal ganglia perform action selection, these cortical afferents encode potential “action requests.” Previous

Avian opioid peptides: evolutionary considerations, functional roles and a challenge to address critical questions

open access: yesFrontiers in Physiology, 2023
The present review considers the putative hormonal opioid peptides in birds. In birds and all other vertebrates, there are four opioid related genes encoding a series of peptides.
