Vesicular glutamate transporter VGLUT2 expression emerges in substantia nigra dopamine neurons in mouse models of parkinsonism in the absence of neurodegeneration

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Subsets of midbrain dopamine (DA) neurons express the vesicular glutamate transporter VGLUT2 and can release the excitatory neurotransmitter glutamate. VGLUT2+ DA neurons of the substantia nigra pars compacta (SNc) were shown to be more resistant to neurodegeneration in animal models of Parkinson's disease (PD ...

Profiling of HCAR1 signalling reveals Gαi/o and Gαs activation without β‐arrestin recruitment and the discovery of an allosteric agonist

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Lactate, historically viewed as a metabolic by‐product, has emerged as a signalling molecule via the G protein–coupled receptor Hydroxycarboxylic Acid Receptor 1 (HCAR1). The receptor is primarily expressed in adipocytes but also found in various other tissues.

Matsupexole: A novel nonergot dopamine receptor agonist with sustained efficacy in a rat model of Parkinson's disease and limited off‐target activity

British Journal of Pharmacology, EarlyView.
Background and Purpose Dopamine receptor agonists, particularly targeting the dopamine D2L receptor (D2LR), have been used to treat Parkinson's disease (PD). However, valvular heart disease and somnolence, mainly caused by activating the serotonin 5‐HT2B receptor (5‐HT2BR) and dopamine D3 receptor (D3R), respectively, currently challenge their clinical

Dopamine D2 antagonist-induced striatal Nur77 expression requires activation of mGlu5 receptors by cortical afferents

Frontiers in Pharmacology, 2012
Dopamine D2 receptor antagonists modulate gene transcription in the striatum. However, the molecular mechanism underlying this effect remains elusive. Here we used the expression of Nur77, a transcription factor of the orphan nuclear receptor family, as ...

Drug Repurposing Screen Identifies Pimozide as a ROS‐Inducing Therapy With Anti‐Tumor Efficacy in HNSCC PDX Models

Cancer Science, EarlyView.
A drug repurposing screen for reactive oxygen species (ROS)‐inducing compounds identified Pimozide as a potent anti‐tumor agent in head and neck squamous cell carcinoma (HNSCC) patient‐derived xenograft (PDX) models. Combined treatment with paclitaxel markedly reduced undifferentiated tumor cells.

Pharmacokinetics and adverse effects of a long‐acting IM dopamine agonist: Cabergoline in healthy horses

Equine Veterinary Education, EarlyView.
Summary Background Pituitary pars intermedia dysfunction (PPID) is commonly treated with pergolide mesylate, a dopamine receptor agonist. Cabergoline is a dopamine receptor agonist that has shown activity on prolactin secretion in horses for up to 10 days.

Involvement of Dopaminergic Receptor Signaling in the Effects of Glutamatergic Receptor Antagonists on Conditioned Place Aversion Induced by Naloxone in Single-Dose Morphine-Treated Rats

Journal of Pharmacological Sciences, 2011
.: A better understanding of the neurochemical mechanisms mediating the aversive consequences of drug withdrawal is important for understanding drug addiction. We previously demonstrated that the inhibitory effect of glutamate receptor antagonists on the

D1/D5 receptor activation promotes long‐term potentiation and synaptic tagging/capture in hippocampal area CA2

The FEBS Journal, EarlyView.
Activation of dopamine receptor D1 (D1R) stimulates PKA and ERK pathways via dissociation of stimulatory and olfactory G protein alpha subunits (Gαs/olf). PKA relieves striatal‐enriched protein tyrosine phosphatase (STEP) inhibition of ERK, promoting cyclic adenosine monophosphate response element‐binding protein (CREB)‐driven transcription of ...

The dopamine D1 receptor is expressed and induces CREB phosphorylation and MUC5AC expression in human airway epithelium

Respiratory Research, 2018
Background Dopamine receptors comprise two subgroups, Gs protein-coupled “D1-like” receptors (D1, D5) and Gi-coupled “D2-like” receptors (D2, D3, D4). In airways, both dopamine D1 and D2 receptors are expressed on airway smooth muscle and regulate airway
