Basal ganglia neuropeptides show abnormal processing associated with L-DOPA-induced dyskinesia
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

Background: Chronic pruritus affects up to 70% of patients with immune-mediated hepatobiliary disorders. Antagonists of the μ-opioid receptor (MOR) and agonists of the κ-opioid receptor (KOR) are used to treat hepatic itch, albeit with limited success ...

Gonadotropin-releasing hormone (GnRH) neurons in the basal forebrain are the final common pathway through which the brain regulates reproduction. GnRH secretion occurs in a pulsatile manner, and indirect evidence suggests the kisspeptin neurons in the ...

A specific antiserum was prepared against dynorphin B, an endogenous opioid peptide contained in a recently isolated 4,000-dalton dynorphin. The antiserum did not crossreact with dynorphin A, alpha-neo-endorphin, beta-neo-endorphin, dynorphin-(1-8), or ...

Dynorphin Controls the Gain of an Amygdalar Anxiety Circuit
Kappa opioid receptors (KORs) are involved in a variety of aversive behavioral states, including anxiety. To date, a circuit-based mechanism for KOR-driven anxiety has not been described.

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

The necessity and functional significance of neurotransmitter co-transmission remains unclear. The glutamatergic ‘KNDy’ neurons co-express kisspeptin, neurokinin B (NKB), and dynorphin and exhibit a highly stereotyped synchronized behavior that reads out

Isolation and amino acid sequence analysis of a 4,000-dalton dynorphin from porcine pituitary [PDF]
A 4,000-dalton dynorphin was isolated from porcine pituitary. It has 32 amino acids (Mr = 3,986), with the previously described heptadecapeptide (now called dynorphin A) at its amino terminus and a related tridecapeptide, dynorphin B, at its carboxyl ...

Functional differences between neurochemically defined populations of inhibitory interneurons in the rat spinal dorsal horn [PDF]
In order to understand how nociceptive information is processed in the spinal dorsal horn we need to unravel the complex synaptic circuits involving interneurons, which constitute the vast majority of the neurons in laminae I–III. The main limitation has

Opioid receptors are differentially coupled to ion channels. Mu- and delta-opioid receptors are coupled to calcium- and/or voltage-dependent potassium channels and kappa-opioid receptors are coupled to voltage-dependent calcium channels. Using the single-
