Pathobiology of dynorphins in trauma and disease. [PDF]
Frontiers in Bioscience, 2005 Dynorphins, endogenous opioid neuropeptides derived from the prodynorphin gene, are involved in a variety of normative physiologic functions including antinociception and neuroendocrine signaling, and may be protective to neurons and oligodendroglia via ...

Membrane leakage induced by dynorphins
FEBS Letters, 2006 Dynorphins, endogeneous opioid peptides, function as ligands to the opioid kappa receptors and induce non‐opioid excitotoxic effects. Here we show that big dynorphin and dynorphin A, but not dynorphin B, cause leakage effects in large unilamellar phospholipid vesicles (LUVs).

Characterization of big dynorphins from rat brain and spinal cord [PDF]
Journal of Neuroscience, 1987 To examine the processing of products of the dynorphin gene in the central nervous system, immunoreactive (ir) dynorphin (Dyn) A, Dyn B, Dyn A-(1-8), alpha- and beta-neo-endorphin (alpha- and beta-Neo) in rat brain and spinal cord were measured, using ...

Stress Produces Aversion and Potentiates Cocaine Reward by Releasing Endogenous Dynorphins in the Ventral Striatum to Locally Stimulate Serotonin Reuptake [PDF]
Journal of Neuroscience, 2012 Activation of the dynorphin/κ-opioid receptor (KOR) system by repeated stress exposure or agonist treatment produces place aversion, social avoidance, and reinstatement of extinguished cocaine place preference behaviors by stimulation of p38α MAPK, which

Frontiers in Neural Circuits, 2022 The olfactory tubercle (OT) is a striatal region that receives olfactory inputs. mRNAs of prodynorphin (Pdyn) and preproenkephalin (Penk), precursors of dynorphins and enkephalins, respectively, are strongly expressed in the striatum. Both produce opioid

Molecules, 2021 Neuropeptides serve as neurohormones and local paracrine regulators that control neural networks regulating behavior, endocrine system and sensorimotor functions. Their expression is characterized by exceptionally restricted profiles.

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.
