Such plasticity has been described in a number of messenger systems, including substance P, calcitonin gene-related peptide, cholecystokinin, and neuropeptide Y. 6,7 We recently demonstrated that such plasticity also occurs in the spinal melanocortin system, as demonstrated by an up-regulation of melanocortin-4 (MC 4 ) receptors in the spinal cord dorsal horn in a rat model for neuropathic pain, the chronic constriction injury (CCI). (silverchair.com)
Furthermore, extended opioid exposure also can elicit increased calcitonin gene related peptide (CGRP) and substance P expression in the dorsal root ganglia. (opioids.wiki)

Receptor ligands1
In chronic constriction injury rats, melanocortin and opioid receptor ligands were administered through a lumbar spinal catheter, and their effects on mechanical allodynia were assessed by von Frey probing. (silverchair.com)
Antagonists1
Together, these data confirm that there is an interaction between the spinal melanocortin and opioid systems and that combined treatment with melanocortin-4 receptor antagonists and opioids might possibly contribute to the treatment of neuropathic pain. (silverchair.com)
Glucagon-like peptide1
In patients with type 2 diabetes mellitus who are overweight or obese, antidiabetic medications that have additional actions to promote weight loss (such as glucagon-like peptide-1 [GLP-1] analogs or sodium-glucose-linked transporter-2 [SGLT-2] inhibitors) are suggested, in addition to the first-line agent for type 2 diabetes mellitus and obesity, metformin.

Hormone4
Cholecystokinin tetrapeptide (CCK-4, tetragastrin, Trp-Met-Asp-Phe-NH2) is a peptide fragment derived from the larger peptide hormone cholecystokinin. (wikipedia.org)
WGA blocks the action of the intestinal hormone, cholecystokinin, reducing bile release from the gallbladder (and causing bile stasis that leads to gallstones) and enzyme release from the pancreas, effects that impair digestion and cultivate dysbiosis. (undoctored.com)
Given historical focus on the roles for cholecystokinin (CCK) as a peripheral hormone controlling gastrointestinal processes and a brainstem peptide regulating food intake, the study of CCK as a limbic neuromodulator coordinating reward-seeking and emotional behavior remains underappreciated.

Endogenous1
In this article we review the endogenous opioid and cannabinoid systems in the hippocampus. (uandes.cl)
Spinal4
The authors hypothesised that there is a balance between tonic pronociceptive effects of the spinal melanocortin system and tonic antinociceptive effects of the spinal opioid system. (silverchair.com)
Therefore, they investigated a possible interaction between these two systems and tested whether opioid effectiveness could be increased through modulation of the spinal melanocortin system activity. (silverchair.com)
A cascade of pronociceptive events may follow, such as opioid-induced upregulation of spinal dynorphin levels that promotes enhanced input from primary afferent nociceptors. (opioids.wiki)
Taken together, such studies show that opioids elicit systems-level adaptations resulting in pain due to descending facilitation, upregulation of spinal dynorphin, and enhanced, evoked release of excitatory transmitters from primary afferents. (opioids.wiki)

Motilin1
successfully identified a human motilin receptor using the Phoenix Gastrointestinal Peptide Library and HEK293 cells in which a human motilin receptor was coexpressed with aequorin, a bioluminescent calcium sensitive reporter protein. (phoenixbiotech.net)
Hyperalgesia1
While the concept that tolerance can develop as a result of cellular adaptations to the presence of the opioid has been proposed, it is now becoming abundantly clear that tolerance may also be related to a state of hyperalgesia that results from exposure to the opioid itself. (opioids.wiki)
Antinociceptive2
Naloxone (10-100 microg) dose-dependently increased allodynia (percent of maximum possible effect of -67 +/- 9%), which is in agreement with a tonic antinociceptive effect of the opioid system. (silverchair.com)
It is probable that increased pain elicited by opioids is a critical factor in the behavioral manifestation of opioid tolerance because the same manipulations that block abnormal pain also block antinociceptive tolerance. (opioids.wiki)
Affinity1
1993. A number of groups have identified a heterozygous missense mutation (Arg236Gly) in POMC that disrupts the dibasic amino acid processing site between b-MSH and b-endorphin, resulting in an aberrant b-MSHb-endorphin tradibg peptide which binds to MC4R with an affinity identical to that of a- and b-MSH but has a markedly reduced ability to activate the receptor (Challis et al.
