Challenges and new opportunities for detecting endogenous opioid peptides in reward
Addiction Neuroscience, 2022 The endogenous opioid peptide system, comprised of enkephalins, endorphins, dynorphins, and nociceptin, is a highly complex neurobiological system. Opioid peptides are derived from four precursor molecules and undergo several processing events yielding ...

Basal ganglia neuropeptides show abnormal processing associated with L-DOPA-induced dyskinesia
npj Parkinson's Disease, 2022 L-DOPA administration is the primary treatment for Parkinson’s disease (PD) but long-term administration is usually accompanied by hyperkinetic side-effects called L-DOPA-induced dyskinesia (LID). Signaling neuropeptides of the basal ganglia are affected

Involvement of the Opioid Peptide Family in Cancer Progression
Biomedicines, 2023 Peptides mediate cancer progression favoring the mitogenesis, migration, and invasion of tumor cells, promoting metastasis and anti-apoptotic mechanisms, and facilitating angiogenesis/lymphangiogenesis.

Dynorphin, stress, and depression [PDF]
Brain Research, 2010 Stress is most often associated with aversive states. It rapidly induces the release of hormones and neuropeptides including dynorphin, which activates kappa opioid receptors (KORs) in the central and peripheral nervous systems. In animal models, many aversive effects of stress are mimicked or exacerbated by stimulation of KORs in limbic brain regions.

Opioid precursor protein isoform is targeted to the cell nuclei in the human brain [PDF]
, 2017 Background: Neuropeptide precursors are traditionally viewed as proteins giving rise to small neuropeptide molecules. Prodynorphin (PDYN) is the precursor protein to dynorphins, endogenous ligands for the kappa-opioid receptor.

Downregulation of the endogenous opioid peptides in the dorsal striatum of human alcoholics
Frontiers in Cellular Neuroscience, 2015 The endogenous opioid peptides dynorphins and enkephalins may be involved in brain-area specific synaptic adaptations relevant for different stages of an addiction cycle.

Endogenous opioid systems alterations in pain and opioid use disorder
Frontiers in Systems Neuroscience, 2022 Decades of research advances have established a central role for endogenous opioid systems in regulating reward processing, mood, motivation, learning and memory, gastrointestinal function, and pain relief.

Projection neurons in lamina III of the rat spinal cord are selectively innervated by local dynorphin-containing excitatory neurons [PDF]
, 2012 Large projection neurons in lamina III of the rat spinal cord that express the neurokinin 1 receptor are densely innervated by peptidergic primary afferent nociceptors and more sparsely by low-threshold myelinated afferents. However, we know little about
