Positive modulation of glucagon‐like peptide 1 (GLP‐1) receptor by endogenous haemorphins with implications in glucose metabolism and diabetes

British Journal of Pharmacology, EarlyView.
Haemorphins act on GLP‐1 receptor (GLP‐1R) activity and signalling in a positive allosteric manner. This leads to potentiated GLP‐1‐mediated activity and signalling, as well as insulin synthesis, which may have implications for glucose metabolism and, thereby, diabetes and obesity.

GLP‐1 receptor activation attenuates chronic migraine‐like behaviour: Sex‐specific modulation of opioid‐ and endocannabinoid‐related pathways

British Journal of Pharmacology, EarlyView.
Background and Purpose Chronic migraine (CM) is a highly disabling condition that remains suboptimally treated. Metabolic disturbances may trigger migraine chronification, whereas impaired endogenous pain inhibition contributes to CM development. Glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs), used for type 2 diabetes and obesity, show efficacy ...

Chronic nicotine treatment impacts the regulation of opioid and non-opioid peptides in the rat dorsal striatum [PDF]

, 2013
The chronic use of nicotine, the main psychoactive ingredient of tobacco smoking, alters diverse physiological processes and consequently generates physical dependence.

Shared dysregulation of complement and phosphorylation pathways in the cerebrospinal fluid of encephalitis, Aicardi–Goutières syndrome, and autism

Developmental Medicine &Child Neurology, EarlyView.
Abstract Aim To identify shared and disorder‐specific molecular alterations across encephalitis, Aicardi–Goutières syndrome (AGS), and autism spectrum disorder (ASD) using cerebrospinal fluid (CSF) proteomics. Method In this cross‐sectional case–control study, mass‐spectrometry‐based proteomics was performed on archived CSF samples collected between ...

Genetically Engineered Human Mesenchymal Stem Cells Produce Met-Enkephalin at Augmented Higher Levels in Vitro

Cell Transplantation, 2006
We have reported that transplantation of adrenal medullary chromaffin cells that release endogenous opioid peptides into pain modulatory regions in the CNS produce significant antinociceptive effects in patients with terminal cancer pain.

Neuropsychiatric Outcomes Associated With GLP‐1 Receptor Agonist Use in Medicare Beneficiaries With Type 2 Diabetes: Variation by Treatment Pattern and Obesity Status

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Glucagon‐like peptide‐1 (GLP‐1) receptors are expressed in brain regions governing mood, reward and stress, yet the neuropsychiatric effects of GLP‐1 receptor agonist (GLP‐1 RA) therapy remain poorly characterized. We estimated associations between GLP‐1 RA use and neuropsychiatric disorders and variation by obesity status and treatment ...

Structural and functional insights into rhodopsin‐like and secretin‐like GPCR–arrestin interactions and regulation

The FEBS Journal, EarlyView.
Distinct GPCR phosphorylation barcodes and arrestin conformational states direct arrestin‐mediated signaling and trafficking. The graphical abstract depicts the structural diversity of GPCR–arrestin complexes by overlaying representative core‐engaged and tail‐engaged conformations.

Biochemical profiling and symptomatology of androgen deficiency in males with cluster headache: A prospective case–control study

Headache: The Journal of Head and Face Pain, EarlyView.
Abstract Objectives/Background Cluster headache (CH) has historically been considered a male‐dominated disorder, suggesting a role for androgens in its pathophysiology. We aimed to evaluate hormone profiles and symptoms of androgen deficiency in CH.
