Studies on dynorphin involvement in epilepsy are summarised in this review. Electrophysiological, biochemical and pharmacological data support the hypothesis that dynorphin is implicated in specific types of seizures. There is clear evidence that this is true for complex partial (limbic) seizures, i.e.

Nonopiate effects of dynorphin and des-Tyr-dynorphin
Science, 1982Intracerebroventricular administration of dynorphin produced potent and long-lasting effects on motor function and the electroencephalogram in rats. In addition, local iontophoretic or pressure ejection of dynorphin consistently inhibited hippocampal unit activity.

Like other opioids, the dynorphins play a role in wide variety of physiological parameters, including pain regulation, motor activity, cardiovascular regulation, respiration, temperature regulation, feeding behavior, hormone balance, and the response to shock or stress. The dynorphins are unusual if not unique, however, in that they frequently modulate

Dynorphin A is increased in neuropathic pain models. Activation of α7 n acetylcholine receptor (nAchR) reduces inflammation and pain. Whether activation of α7 nAchR affects dynorphin A release is unknown.

This study aimed to elucidate the opioid mechanisms underlying dexamethasone-induced pain antihypersensitive effects in neuropathic rats. Dexamethasone (subcutaneous and intrathecal) and membrane-impermeable Dex-BSA (intrathecal) administration dose ...

Rimorphin (dynorphin B) has been demonstrated to exist together with alpha-neo-endorphin and dynorphin(1-17) (dynorphin A) in the human hypothalamus. The content of rimorphin was comparable to that of alpha-neo-endorphin and somewhat higher than that of dynorphin. This result is quite similar to the recent observations in bovine, porcine and rat neural

AbstractDynorphin B (rimorphin) is formed from leumorphin (dynorphin B‐29) by the action of a thiol protease from rat brain membranes, in a single step. This represents a “single‐arginine cleavage” between threonine‐13 and arginine‐14 of the substrate. We have observed that in addition to dynorphin B, dynorphin B‐14 is formed from dynorphin B‐29.

Dynorphin‐(1–13) (Dyn‐(1–13)) and its analogs substituted by single introduction of Ala in positions 1–11 were synthesized by the solid‐phase method and purified by high pressure liquid chromatography. Relative potencies of the synthetic compounds were determined by their ability to inhibit electrically‐evoked contractions of the guinea pig ileum (GPI)

Dynorphin, won’t you myelinate my neighbor?
Neuron, 2021Accumulating evidence supports the prevalence of experience-dependent oligodendrocyte precursor cell (OPC) differentiation and myelination in learning and memory. However, the mechanisms remain unknown. In this issue of Neuron, Osso et al., (2021) report that stress causes the secretion of dynorphin by unmyelinated axons, which induces OPC ...
