Opioid peptides in the female reproductive system: physiological implications

, 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

Neuroimmune Interaction in the Regulation of Peripheral Opioid-mediated Analgesia in Inflammation

Frontiers in Immunology, 2016
Peripheral immune-cell-mediated analgesia in inflammation is an important endogenous mechanism of pain control. Opioid receptors localized on peripheral sensory nerve terminals are activated by endogenous opioid peptides released from immune cells to ...

Opioid peptide-derived analgesics [PDF]

The AAPS Journal, 2005
Two recent developments of opioid peptide-based analgesics are reviewed. The first part of the review discusses the dermorphin-derived, cationic-aromatic tetrapeptide H-Dmt-D-Arg-Phe-Lys-NH(2) ([Dmt(1)]DALDA, where Dmt indicates 2',6'-dimethyltyrosine), which showed subnanomolar mu receptor binding affinity, extraordinary mu receptor selectivity, and ...

Lesion Site‐Targeted Microspheres Modulate Nav1.7‐Related Signaling for Osteoarthritis Treatment

Advanced Science, EarlyView.
Cartilage‐targeted carbamazepine‐loaded WYRGRL‐modified composite microspheres (CBZ/WCOM) anchor to exposed type II collagen in osteoarthritic lesions and release carbamazepine under acidic conditions. This bind‐then‐release platform modulates Nav1.7‐related sodium signaling, Na⁺/Ca²⁺ exchanger‐associated Ca2+ dynamics, and heat shock protein 70 ...

Glycosylated dendrimer nanoamplifiers hijack DNA damage‐immune crosstalk for enhanced dual‐track therapy of orthotopic glioblastoma

BMEMat, EarlyView.
A glycosylated dendrimer nanoamplifier hijacks DNA damage‐immune crosstalk for enhanced radio‐immunotherapy of glioblastoma. The responsive release of demethylcantharidin simultaneously blocks repair‐mediated resistance by inhibiting DNA repair and overcomes adaptive immune resistance.

Antinociceptive potency of a fluorinated cyclopeptide Dmt-c[D-Lys-Phe-p-CF3-Phe-Asp]NH2

Journal of Enzyme Inhibition and Medicinal Chemistry, 2018
Opioid peptides and opiate drugs such as morphine, mediate their analgesic effects, but also undesired side effects, mostly through activation of the mu opioid receptor.

Expression and Localization of Opioid Receptors in Male Germ Cells and the Implication for Mouse Spermatogenesis. [PDF]

PLoS ONE, 2016
The presence of endogenous opioid peptides in different testicular cell types has been extensively characterized and provides evidence for the participation of the opioid system in the regulation of testicular function.

GLP‐1 Receptor Agonists and Endoscopy: Understanding Gastric Stasis, Aspiration Risk, and Contemporary Peri‐Procedural Guidance

Chronic Diseases and Translational Medicine, EarlyView.
Pharmacological mechanisms and physiologic effects of GLP‐1 receptor agonists relevant to peri‐endoscopic risk. ABSTRACT The global increase in obesity, type 2 diabetes mellitus (T2DM), and metabolic dysfunction‐associated steatotic liver disease (MASLD) has led to a higher use of glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) among patients ...

Opioid peptides

, 1997
Opioid peptides produced in the body act as neuromodulators that modify the actions of other neurotransmitters in the central nervous system. By altering the electrical properties of their target neurons, thereby making these neurons more difficult to ...
