Projection neurons in lamina III of the rat spinal cord are selectively innervated by local dynorphin-containing excitatory neurons [PDF]

open access: yes, 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

Projection-Target-Defined Effects of Orexin and Dynorphin on VTA Dopamine Neurons.

open access: yesCell Reports, 2017
Circuit-specific signaling of ventral tegmental area (VTA) dopamine neurons drives different aspects of motivated behavior, but the neuromodulatory control of these circuits is unclear. We tested the actions of co-expressed lateral hypothalamic peptides,

CRF1-R activation of the dynorphin/kappa opioid system in the mouse basolateral amygdala mediates anxiety-like behavior.

open access: yesPLoS ONE, 2009
Stress is a complex human experience and having both rewarding and aversive motivational properties. The adverse effects of stress are well documented, yet many of underlying mechanisms remain unclear and controversial. Here we report that the anxiogenic

Rapid-Onset Anti-Stress Effects of a Kappa-Opioid Receptor Antagonist, LY2795050, Against Immobility in an Open Space Swim Paradigm in Male and Female Mice

open access: yesFrontiers in Pharmacology, 2021
The kappa-opioid receptor (KOR) / dynorphin system is implicated with behavioral and neurobiological effects of stress exposure (including heavy exposure to drugs of abuse) in translational animal models.

Opioid Receptors in Immune and Glial Cells-Implications for Pain Control [PDF]

open access: yes, 2020
Opioid receptors comprise μ (MOP), δ (DOP), κ (KOP), and nociceptin/orphanin FQ (NOP) receptors. Opioids are agonists of MOP, DOP, and KOP receptors, whereas nociceptin/orphanin FQ (N/OFQ) is an agonist of NOP receptors.

Estradiol treatment prevents injury induced enhancement in spinal cord dynorphin expression.

open access: yesFrontiers in Physiology, 2012
Administration of the ovarian steroid estradiol in male and female animals has been shown to have neuromodulatory and neuroprotective effects in a variety of experimental models. In the present study, spinal tissues from dermatomes just above (T5-7, at

The Role of the Brain in the Pathogenesis and Physiology of Polycystic Ovary Syndrome (PCOS). [PDF]

open access: yes, 2019
Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder, affecting at least 10% of women of reproductive age. PCOS is typically characterized by the presence of at least two of the three cardinal features of hyperandrogenemia (high ...

Hypothalamic Reproductive Endocrine Pulse Generator Activity Independent of Neurokinin B and Dynorphin Signaling.

open access: yesJournal of Clinical Endocrinology and Metabolism, 2019
CONTEXT Kisspeptin-Neurokinin B-Dynorphin neurons are critical regulators of the hypothalamic-pituitary-gonadal axis. Neurokinin B (NKB) and dynorphin are hypothesized to influence the frequency of gonadotropin-releasing hormone (GnRH) pulses; whereas ...

Alterations in Cortical and Basal Ganglia Levels of Opioid Receptor Binding in a Rat Model of l-DOPA-Induced Dyskinesia

open access: yesNeurobiology of Disease, 2001
Opioid receptor-binding autoradiography was used as a way to map sites of altered opioid transmission in a rat model of l-DOPA-induced dyskinesia. Rats with unilateral 6-hydroxydopamine lesions of the nigrostriatal pathways sustained a 3-week treatment ...

Acute Wheel-Running Increases Markers of Stress and Aversion-Related Signaling in the Basolateral Amygdala of Male Rats

open access: yesJournal of Functional Morphology and Kinesiology, 2022
Physical activity (PA) is a non-invasive, cost-effective means of reducing chronic disease. Most US citizens fail to meet PA guidelines, and individuals experiencing chronic stress are less likely to be physically active.
