Nature Network Boston, 2016 Opioid pain medications have detrimental side effects including analgesic tolerance and opioid-induced hyperalgesia (OIH). Tolerance and OIH counteract opioid analgesia and drive dose escalation.

Advanced Science, EarlyView.Graphic illustration showing the strategic approaches based on the currently investigated evidence of psychedelics that suggests the challenges and how to address the prescription of mental disorders. These applicable avenues may provide substantial insight into distinguishing between brain networks and psychedelics.

Cellular Tolerance Induced by Chronic Opioids in the Central Nervous System
Frontiers in Systems Neuroscience, 2022 Opioids are powerful analgesics that elicit acute antinociceptive effects through their action the mu opioid receptor (MOR). However opioids are ineffective for chronic pain management, in part because continuous activation of MORs induces adaptive ...

Binding Pathway of Opiates to $μ$ Opioid Receptors Revealed by Unsupervised Machine Learning [PDF]
, 2018 Many important analgesics relieve pain by binding to the $\mu$-Opioid Receptor ($\mu$OR), which makes the $\mu$OR among the most clinically relevant proteins of the G Protein Coupled Receptor (GPCR) family. Despite previous studies on the activation pathways of the GPCRs, the mechanism of opiate binding and the selectivity of $\mu$OR are largely ...

Opioid and cannabinoid receptors
Current Opinion in Neurobiology, 1994 Opioids and cannabinoids are two major classes of drugs with important clinical uses as well as significant side effects. Recently, the three major subtypes of opioid receptors, delta, kappa and mu, have been cloned. Both the endogenous cannabinoids and their receptors have also recently been cloned.

Advanced Science, EarlyView.Intratracheal neomycin alters pulmonary microbiota, activating the vagus nerve via lung brain‐derived neurotrophic factor/tropomyosin receptor kinase B (BDNF/TrkB) pathway, further projecting to nucleus of solitary tract (NTS), then dorsal raphe nucleus (DRN), where activated serotoninergic neurons increase brain serotonin, alleviating migraine.

Opposite effects of neuropeptide FF on central antinociception induced by endomorphin-1 and endomorphin-2 in mice. [PDF]
PLoS ONE, 2014 Neuropeptide FF (NPFF) is known to be an endogenous opioid-modulating peptide. Nevertheless, very few researches focused on the interaction between NPFF and endogenous opioid peptides. In the present study, we have investigated the effects of NPFF system

Placenta ingestion by rats enhances d- and k-opioid antinociception, but suppresses m-opioid antinociception [PDF]
, 2004 Ingestion of placenta or amniotic fluid produces a dramatic enhancement of centrally mediated opioid antinociception in the rat. The present experiments investigated the role of each opioid receptor type (m, d, k) in the antinociception-modulating ...

Stress-Dependent Impairment Of Passive-Avoidance Memory By Propranolol Or Naloxone [PDF]
, 2011 Previous work has shown that the effect of opioid-receptor blockade on memory modulation is critically dependent upon the intensity of stress. The current study determined the effect of adrenergic-receptor blockade on memory modulation under varied ...
