Involvement of cytokines, chemokines and adhesion molecules in opioid analgesia

Tissue destruction is accompanied by an inflammatory reaction. The inflammatory reaction leads to activation of nociceptors and the sensation of pain. Several mediators are responsible for pain and hyperalgesia in inflammation including cytokines,…

Leukocytes in the regulation of pain and analgesia

When tissue is destroyed or invaded by leukocytes in inflammation, numerous mediators are delivered by the circulation and/or liberated from resident and immigrated cells at the site. Proalgesic mediators include proinflammatory cytokines,…

Control of inflammatory pain by chemokine-mediated recruitment of opioid-containing polymorphonuclear cells

Opioid-containing leukocytes can counteract inflammatory hyperalgesia. Under stress or after local injection of corticotropin releasing factor (CRF), opioid peptides are released from leukocytes, bind to opioid receptors on peripheral sensory neurons…

Modulation of peripheral endogenous opioid analgesia by central afferent blockade

BACKGROUND: Peripheral tissue injury causes a migration of opioid peptide-containing immune cells to the inflamed site. The subsequent release and action of these peptides on opioid receptors localized on peripheral sensory nerve terminals causes…

Mobilization of opioid-containing polymorphonuclear cells by hematopoietic growth factors and influence on inflammatory pain

BACKGROUND: Leukocytes can control inflammatory pain by secretion of opioid peptides, stimulated by cold-water swimming or local injection of corticotropin-releasing factor, and subsequent activation of opioid receptors on peripheral sensory neurons.…

Tissue monocytes/macrophages in inflammation: hyperalgesia versus opioid-mediated peripheral antinociception

BACKGROUND: Opioid-containing leukocytes migrate to peripheral sites of inflammation. On exposure to stress, opioid peptides are released, bind to opioid receptors on peripheral sensory neurons, and induce endogenous antinociception. In later stages…

Opioid peptide-expressing leukocytes: identification, recruitment, and simultaneously increasing inhibition of inflammatory pain

BACKGROUND: Inflammatory pain can be effectively controlled by an interaction of opioid receptors on peripheral sensory nerve terminals with opioid peptides released from immune cells upon stressful stimulation. To define the source of opioid peptide…
