Compartment-specific opioid receptor signaling is selectively modulated by different dynorphin peptides

eLife, 2021
Many signal transduction systems have an apparent redundancy built into them, where multiple physiological agonists activate the same receptors. Whether this is true redundancy, or whether this provides an as-yet unrecognized specificity in downstream ...

Cannabis sativa and the endogenous cannabinoid system: therapeutic potential for appetite regulation [PDF]

, 2011
The herb Cannabis sativa (C. sativa) has been used in China and on the Indian subcontinent for thousands of years as a medicine. However, since it was brought to the UK and then the rest of the western world in the late 19th century, its use has been a ...

Opioid suppression of conditioned anticipatory brain responses to breathlessness [PDF]

, 2017
© 2017 The Authors Opioid painkillers are a promising treatment for chronic breathlessness, but are associated with potentially fatal side effects. In the treatment of breathlessness, their mechanisms of action are unclear.

Inhibition of activity of GABA transporter GAT1 by δ-opioid receptor [PDF]

, 2012
Analgesia is a well-documented effect of acupuncture. A critical role in pain sensation plays the nervous system, including the GABAergic system and opioid receptor (OR) activation.

Delta Opioid Receptors within the Cortico‐Thalamic Circuitry Underlie Hyperactivity Induced by High‐Dose Morphine

Advanced Science, EarlyView.
Morphine activates the excitatory cingulate cortex–intermediate rostrocaudal division of zona incerta (Cg‐ZIm) pathway to drive hyperlocomotion in mice. Inhibiting the Cg‐ZIm pathway attenuates both acute and chronic morphine‐induced hyperlocomotion, while its activation mimics morphine's motor effects.

In Vivo Regulation of the μ Opioid Receptor: Role of the Endogenous Opioid Agents

Molecular Medicine, 2013
It is well known that genotypic differences can account for the subject-specific responses to opiate administration. In this regard, the basal activity of the endogenous system (either at the receptor or ligand level) can modulate the effects of ...

Interactions of the opioid and cannabinoid systems in reward: Insights from knockout studies

Frontiers in Pharmacology, 2015
The opioid system consists of three receptors, mu, delta, and kappa, which are activated by endogenous opioid peptides (enkephalins, endorphins and dynorphins). The endogenous cannabinoid system comprises lipid neuromodulators (endocannabinoids), enzymes

Esketamine/Ketamine: Dual‐Action Mechanisms and Clinical Prospects beyond Anesthesia in Psychiatry, Immunology, and Oncology

Advanced Science, EarlyView.
Esketamine and ketamine are widely used for perioperative analgesia and anesthesia. Despite their established roles in analgesia, sedation, and anesthesia, as well as emerging antidepressant, anti‐tumor, and anti‐inflammatory effects, their clinical use is limited due to side effects and addiction potential.

GPCRs in CAR‐T Cell Immunotherapy: Expanding the Target Landscape and Enhancing Therapeutic Efficacy

Advanced Science, EarlyView.
Chimeric antigen receptor T cell therapy faces dual challenges of target scarcity and an immunosuppressive microenvironment in solid tumors. This review highlights how G protein‐coupled receptors can serve as both novel targets to expand the therapeutic scope and functional modules to enhance CAR‐T cell efficacy.

A Randomized, Sham‐Controlled Trial of Repetitive Transcranial Magnetic Stimulation Targeting M1 and S2 in Central Poststroke Pain: A Pilot Trial

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Central poststroke pain (CPSP), a neuropathic pain condition, is difficult to treat. Repetitive transcranial magnetic stimulation (rTMS) targeted to the primary motor cortex (M1) can alleviate the condition, but not all patients respond. We aimed to assess a promising alternative rTMS target, the secondary somatosensory cortex (S2),
