beta-endorphin-(1-27) is an antagonist of beta-endorphin analgesia. [PDF]

open access: greenProceedings of the National Academy of Sciences, 1984
beta h-Endorphin-(1-27), a naturally occurring fragment of human beta-endorphin (beta h-endorphin), diminishes the analgesic effect of beta h-endorphin when coinjected intra-cerebroventricularly into mice. A parallel shift in the dose-response curve of beta h-endorphin in the presence of beta h-endorphin-(1-27) suggests competition at the same site ...

beta-endorphin is a potent analgesic agent. [PDF]

open access: greenProceedings of the National Academy of Sciences, 1976
beta-Endorphin, an opiate-like peptide, has potent antinociceptive properties when it is administered directly into the brain and assayed in the the tail-flick, hot-plate, and writhing tests in mice and in the wet shake test in rats. On a molar basis, beta-endorphin is 18 to 33 times more potent than morphine and its actions are blocked by the specific

Biotransformation of beta-endorphin and possible therapeutic implications [PDF]

open access: yesFrontiers in Pharmacology, 2014
Endogenous opioid peptides have been aligned with a diverse array of effects. Their activity is not only attributable to action the three main opioid receptors, mu (MOR), delta (DOR), and kappa (KOR) opioid receptors but their impacts appear to extend to activities at sodium channels, cytokine receptors (Finley et al., 2008), calcium channels and non ...

The Role of Beta-Endorphin in Cocaine-Induced Conditioned Place Preference, Its Extinction, and Reinstatement in Male and Female Mice

open access: yesFrontiers in Behavioral Neuroscience, 2021
Endogenous opioids have been implicated in cocaine reward. However, the role of each opioid peptide in this regard is unknown. Notably, the role of each peptide in extinction and reinstatement is not fully characterized. Thus, we assessed whether cocaine-

The Role of Beta-Endorphin in Food Deprivation-Mediated Increases in Food Intake and Binge-Eating

open access: yesBrain Sciences, 2023
Food deprivation and binge eating represent significant public health concerns. Previous studies have implicated that hypothalamic opioids are affected following food deprivation.

AAV gene therapy vectors in the TMJ

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1561-1566, December 2022., 2022
Abstract Objectives The goal of this project was to evaluate the use of two adeno‐associated viral vector serotypes, adeno‐associated viral vectors (AAV)‐2 and AAV‐6, approved for and used for gene therapy in humans, for the delivery of therapeutic genes to the temporomandibular joint (TMJ) and the attendant sensory nerves.

Within‐day bidirectional associations between physical activity and affect: A real‐time ambulatory study in persons with and without depressive and anxiety disorders

open access: yesDepression and Anxiety, Volume 39, Issue 12, Page 922-931, December 2022., 2022
Abstract Background Ambulatory assessments offer opportunities to study physical activity level (PAL) and affect at the group and person‐level. We examined bidirectional associations between PAL and affect in a 3‐h timeframe and evaluated whether associations differ between people with and without current or remitted depression/anxiety.
