Correlation between ovarian steroidogenesis and beta-endorphin in the Lizard Uromastyx acanthinura: Immunohistochemical approach.

Folia Histochemica et Cytobiologica, 2010
In Mammals, opioid peptides are involved in various physiological processes including the reproductive function. The knowledge of the distribution of beta-endorphin, one of opioid peptides in Reptiles ovaries is very limited. Therefore, the present study

The Allosteric Mechanism of G‐Protein‐Coupled Receptors is Induced Fit, Not Conformational Selection

BioEssays, EarlyView.
Allosteric signaling of G‐protein‐coupled receptors (GPCRs) involves a population shift from inactive to active receptor conformations upon binding of ligand agonists. Kinetic and structural data indicate that this population shift is induced by ligand binding to inactive receptor conformations prior to the conformational change from inactive to active.

The Multimodal MOPr/DOPr Agonist LP2 Reduces Allodynia in Chronic Constriction Injured Rats by Rescue of TGF-β1 Signalling

Frontiers in Pharmacology, 2021
Neuropathic pain is one of the most disabling forms of chronic pain and it is characterized by hyperalgesia and allodynia linked to an aberrant processing of pain transmission and to neuroinflammation.

Exploring the role of beta‐endorphin in activity‐based anorexia in mice

Physiological Reports
Anorexia nervosa (AN) remains one of the most lethal mental health disorders and is poorly understood from a neurobiological perspective. The most widely used animal model of AN is activity‐based anorexia (ABA) where scheduled food presentation leads to ...
