β‐endorphin differentially contributes to food anticipatory activity in male and female mice undergoing activity‐based anorexia [PDF]
Physiological Reports, 2021 Anorexia nervosa (AN) has a lifetime prevalence of up to 4% and a high mortality rate (~5–10%), yet little is known regarding the etiology of this disease.

Activation of GPR40 produces mechanical antiallodynia via the spinal glial interleukin-10/β-endorphin pathway [PDF]
Journal of Neuroinflammation, 2019 Background The G protein-coupled receptor 40 (GPR40), broadly expressed in various tissues such as the spinal cord, exerts multiple physiological functions including pain regulation.

The Effects of Androstenone on the Plasma Serotonin, β-Endorphin, and Cortisol Concentrations in Thoroughbred Horses [PDF]
Animals, 2021 Androstenone influences the changing behaviors of animals. Previous studies discovered that an androstenone receptor was expressed in horses and treatment with androstenone induced horses to be more compliant.

The spinal microglial IL-10/β-endorphin pathway accounts for cinobufagin-induced mechanical antiallodynia in bone cancer pain following activation of α7-nicotinic acetylcholine receptors [PDF]
Journal of Neuroinflammation, 2020 Background Cinobufagin is the major bufadienolide of Bufonis venenum (Chansu), which has been traditionally used for the treatment of chronic pain especially cancer pain. The current study aimed to evaluate its antinociceptive effects in bone cancer pain

Reserpine-induced fibromyalgia model in female rats is a long-lasting painful condition masked by antinociceptive endogenous opioids [PDF]
Frontiers in PharmacologyBackgroundFibromyalgia (FM) is a chronic painful condition that primarily affects women. The allodynia and hyperalgesia induced by reserpine is a FM model commonly used to study the disease; however, it produces one painful episode, in contrast to FM ...

Molecular interpretation of ACTH-β-endorphin coaggregation: relevance to secretory granule biogenesis. [PDF]
PLoS ONE, 2012 Peptide/protein hormones could be stored as non-toxic amyloid-like structures in pituitary secretory granules. ACTH and β-endorphin are two of the important peptide hormones that get co-stored in the pituitary secretory granules. Here, we study molecular

Opioid Receptors in Immune and Glial Cells-Implications for Pain Control [PDF]
, 2020 Opioid receptors comprise μ (MOP), δ (DOP), κ (KOP), and nociceptin/orphanin FQ (NOP) receptors. Opioids are agonists of MOP, DOP, and KOP receptors, whereas nociceptin/orphanin FQ (N/OFQ) is an agonist of NOP receptors.

Endogenous opioid signaling in the retina modulates sleep/wake activity in mice
Neurobiology of Sleep and Circadian Rhythms, 2022 Circadian sleep/wake rhythms are synchronized to environmental light/dark cycles in a process known as photoentrainment. We have previously shown that activation of β-endorphin-preferring μ-opioid receptors (MORs) inhibits the light-evoked firing of ...

Influence of training and competitive sessions on peripheral β-endorphin levels in training show jumping horses [PDF]
Veterinary World, 2017 Aim: To investigate the effects of training sessions on circulating β-endorphin changes in sport horses before and after competition and to ascertain whether competition would affect this response.
