Age-related changes in mitogen-induced beta-endorphin release from human peripheral blood mononuclear cells

beta-Endorphin is an opioid peptide synthesized in the pituitary, hypothalamus, and immunocytes, known to affect immune responses both when added in vitro and when its synthesis is increased in vivo (e.g., during stress). We show here that, similar…

Pain control by immune-derived opioids

1. The nervous and immune systems communicate with each other by use of cytokines and neuropeptides. 2. Interactions between immune cell-derived opioid peptides and opioid receptors located in peripheral inflamed tissue lead to endogenous analgesia.…

Different mechanisms of intrinsic pain inhibition in early and late inflammation

Neuroimmune interactions control pain through activation of opioid receptors on sensory nerves by immune-derived opioid peptides. Here we evaluate mechanisms of intrinsic pain inhibition at different stages of Freund's adjuvant-induced inflammation…

Targeting of opioid-producing leukocytes for pain control

It is accepted that inflammatory mediators released from leukocytes contribute to the generation of pain. However, it is less well known that immune cells also produce mediators that can effectively counteract pain. These include anti-inflammatory…

Recommendations for using opioids in chronic non-cancer pain

1. The management of chronic pain should be directed by the underlying cause of the pain. Whatever the cause, the primary goal of patient care should be symptom control. 2. Opioid treatment should be considered for both continuous neuropathic and…

CB2 cannabinoid receptor activation produces antinociception by stimulating peripheral release of endogenous opioids

CB(2) cannabinoid receptor-selective agonists are promising candidates for the treatment of pain. CB(2) receptor activation inhibits acute, inflammatory, and neuropathic pain responses but does not cause central nervous system (CNS) effects,…

Development of the paediatric pain profile: role of video analysis and saliva cortisol in validating a tool to assess pain in children with severe neurological disability

The Faces Pain Scale-Revised: toward a common metric in pediatric pain measurement

The Faces Pain Scale (FPS; Bieri et al., Pain 41 (1990) 139) is a self-report measure used to assess the intensity of children's pain. Three studies were carried out to revise the original scale and validate the adapted version. In the first phase,…

Influence of pain treatment by epidural fentanyl and bupivacaine on homing of opioid-containing leukocytes to surgical wounds

Endogenous opioids released from leukocytes extravasating into injured tissue can interact with peripheral opioid receptors to inhibit nociception. Animal studies have shown that the homing of opioid-producing leukocytes to the injured site is…
