Cancer pain: current practice and emerging targets

open access: yesBritish Journal of Pharmacology, EarlyView.
Cancer pain (CP) arises from a complex interplay between the tumour and its microenvironment. Many patients experience a mixed pain phenotype that encompasses nociceptive, neuropathic and neuroinflammatory mechanisms, and vary across tumour type and disease stage. Despite decades of intensive research, the mainstay of cancer pain treatment is still non‐

Opioid peptides in the female reproductive system: physiological implications [PDF]

open access: yes, 1995
All endogenous opioid peptides derive from three precursor molecules i.e. proopiomelanocortin, proenkephalin and prodynorphin. The endogenous opioid peptides exert their biological effects through opioid receptors. Each endogenous opioid peptide exhibits

Gut microbiota as a novel therapeutic target for eating disorders and obesity

open access: yesBritish Journal of Pharmacology, EarlyView.
The graphical abstract highlights the bidirectional interaction between the gut microbiota and central homeostatic and hedonic mechanisms regulating food intake, which contributes to overweight and obesity. It also illustrates emerging microbiota‐based biomarkers and therapeutic strategies (including prebiotics, probiotics, postbiotics, synbiotics and ...

Peripheral targets for neuropathic pain

open access: yesBritish Journal of Pharmacology, EarlyView.
Neuropathic pain represents a significant clinical challenge, with still limited pharmacological approaches to symptomatic relief. This review focuses on molecular targets implicated in neuropathic pain, particularly those involved in peripheral mechanisms. Using the IUPHAR/BPS database of biological targets, their occurrence together with ‘neuropathic

Research Note: Morphine influences circulating and tissue concentrations of met-enkephalin and proenkephalin (PENK) expression and plasma concentrations of corticosterone in chickens

open access: yesPoultry Science
: The effects of the administration of the opioid agonist, morphine, on plasma and tissue concentrations of Met-enkephalin were determined in 14 wk old female chickens.

TRYptophan-COntaining Non-Cationizable Opioid PeptideS (TRYCONCOPS): A new paradigm for opioid peptides

open access: yes, 2014
Despite of the current availability of new synthetic drugs, morphine and the other alkaloids found in the opium poppy plant still represent the drugs of choice for the relief of serious pain caused by cancer or other maladies. However, long-term usage is

Regulation of the Estrous Cycle by Neutrophils via Opioid Peptides

open access: yes, 2011
We found previously that neutrophil-depleted mice exhibited significant blockading of both the regular estrous cycle and cyclic changes of steroid hormone levels. In this study, we aimed at elucidation of the underlying mechanism.

Natural product‐derived TRPM7 channel inhibitors in neurological injury: Mechanisms, pharmacological potential and translational challenges

open access: yesBritish Journal of Pharmacology, EarlyView.
Disruption of intracellular ionic homeostasis is a convergent pathological feature across diverse neurological injuries and disorders, including ischaemic and haemorrhagic stroke, hypoxic–ischaemic brain injury, traumatic brain injury, epilepsy and brain tumour.

Sex differences after chronic stress in the expression of opioid-, stress- and neuroplasticity-related genes in the rat hippocampus

open access: yesNeurobiology of Stress, 2018
Opioid peptides and their receptors re-organize within hippocampal neurons of female, but not male, rats following chronic immobilization stress (CIS) in a manner that promotes drug-related learning.
