Isolation and amino acid sequence analysis of a 4,000-dalton dynorphin from porcine pituitary [PDF]
, 1982 A 4,000-dalton dynorphin was isolated from porcine pituitary. It has 32 amino acids (Mr = 3,986), with the previously described heptadecapeptide (now called dynorphin A) at its amino terminus and a related tridecapeptide, dynorphin B, at its carboxyl ...

μ‐Opioid Receptor Dynamics in the Parameningeal Tissue During Migraine Attacks
Annals of Neurology, EarlyView.Objective The possible impact of meningeal μ‐opioid receptor (μOR) binding in migraine remains unknown. This study investigated μOR availability in the cranial parameninges involved in migraine initiation via nociceptor activation. Methods We used positron emission tomography with [11C] carfentanil, and measured μOR availability in meninges and ...

Measuring ligand efficacy at the mu-opioid receptor using a conformational biosensor. [PDF]
, 2018 The intrinsic efficacy of orthosteric ligands acting at G-protein-coupled receptors (GPCRs) reflects their ability to stabilize active receptor states (R*) and is a major determinant of their physiological effects.

Identifying functional populations among the interneurons in laminae I-III of the spinal dorsal horn [PDF]
, 2017 The spinal dorsal horn receives input from primary afferent axons, which terminate in a modality-specific fashion in different laminae. The incoming somatosensory information is processed through complex synaptic circuits involving excitatory and ...

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

Challenges and new opportunities for detecting endogenous opioid peptides in reward
Addiction Neuroscience, 2022 The endogenous opioid peptide system, comprised of enkephalins, endorphins, dynorphins, and nociceptin, is a highly complex neurobiological system. Opioid peptides are derived from four precursor molecules and undergo several processing events yielding ...
