A Theory of Natural Addiction [PDF]

, 2007
Economic theories of rational addiction aim to describe consumer behavior in the presence of habit-forming goods. We provide a biological foundation for this body of work by formally specifying conditions under which it is optimal to form a habit.

Ligand-Specific Regulation of the Endogenous Mu-Opioid Receptor by Chronic Treatment with Mu-Opioid Peptide Agonist [PDF]

, 2013
Since the discovery of the endomorphins (EM), the postulated endogenous peptide agonists of the mu-opioid receptors, several analogues have been synthesized to improve their binding and pharmacological profiles.

Analgesic Effects of Fatty Acid Amide Hydrolase Inhibition in a Rat Model of Neuropathic Pain [PDF]

, 2006
Cannabinoid-based medicines have therapeutic potential for the treatment of pain. Augmentation of levels of endocannabinoids with inhibitors of fatty acid amide hydrolase (FAAH) is analgesic in models of acute and inflammatory pain states.

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

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.

Endogenous opioids regulate moment-to-moment neuronal communication and excitability

Nature Communications, 2017
The endogenous opioid system regulates fear and anxiety, but the underlying cellular mechanism is unclear. Winterset al. shows that in the intercalated cells (ITC) of the amygdala, endogenous opioids suppress glutamatergic inputs via the δ-opioid ...

Endogenous opioid system dysregulation in depression: implications for new therapeutic approaches

Molecular Psychiatry, 2018
The United States is in the midst of an opioid addiction and overdose crisis precipitated and exacerbated by use of prescription opioid medicines. The majority of opioid prescriptions are dispensed to patients with comorbid mood disorders including major

Targeting peripheral opioid receptors to promote analgesic and anti-inflammatory actions

Frontiers in Pharmacology, 2013
Mechanisms of endogenous pain control are significant. Increasing studies have clearly produced evidence for the clinical usefulness of opioids in peripheral analgesia.

CRISPR/Cas9 unveils the dynamics of the endogenous µ‐opioid receptors on neuronal cells under continuous opioid stimulation

Pharmacology Research & Perspectives, 2022
Long‐term opioid use develops tolerance and attenuates analgesic effects. Upon activation, µ‐opioid receptors (MOPs) are internalized and directed to either recycling or degradation pathway. Ligand stimulation also promotes de novo MOP synthesis.
