IUPHAR themed review: Opioid efficacy, bias, and selectivity [PDF]
Pharmacological Research, 2023 Drugs acting at the opioid receptor family are clinically used to treat chronic and acute pain, though they represent the second line of treatment behind GABA analogs, antidepressants and SSRI’s.

Functional modulation of human delta opioid receptor by neuropeptide FF [PDF]
BMC Neuroscience, 2005 Background Neuropeptide FF (NPFF) plays a role in physiological pain sensation and opioid analgesia. For example, NPFF potentiates opiate-induced analgesia and the delta opioid receptor antagonist naltrindole inhibits NPFF-induced antinociception.

Scalable Production of Highly-Sensitive Nanosensors Based on Graphene Functionalized with a Designed G Protein-Coupled Receptor [PDF]
, 2014 We have developed a novel, all-electronic biosensor for opioids that consists of an engineered mu opioid receptor protein, with high binding affinity for opioids, chemically bonded to a graphene field-effect transistor to read out ligand binding. A variant of the receptor protein that provided chemical recognition was computationally redesigned to ...

µ-Opioid receptor antagonism facilitates the anxiolytic-like effect of oxytocin in mice [PDF]
Translational PsychiatryMood and anxiety disorders are leading causes of disability worldwide and are major contributors to the global burden of diseases. Neuropeptides, such as oxytocin and opioid peptides, are important for emotion regulation.

Opioid receptor activation triggering downregulation of cAMP improves effectiveness of anti-cancer drugs in treatment of glioblastoma [PDF]
Cell Cycle, 2014 Glioblastoma are the most frequent and malignant human brain tumors, having a very poor prognosis. The enhanced radio- and chemoresistance of glioblastoma and the glioblastoma stem cells might be the main reason why conventional therapies fail.

Insights into the interaction between hemorphins and δ-opioid receptor from molecular modeling [PDF]
Frontiers in Molecular BiosciencesHemorphins are short atypical opioid peptide fragments embedded in the β-chain of hemoglobin. They have received considerable attention recently due to their interaction with opioid receptors.

Opioid Receptor-Mediated Regulation of Neurotransmission in the Brain
Frontiers in Molecular Neuroscience, 2022 Opioids mediate their effects via opioid receptors: mu, delta, and kappa. At the neuronal level, opioid receptors are generally inhibitory, presynaptically reducing neurotransmitter release and postsynaptically hyperpolarizing neurons.
