Voltage-Dependent Dopamine Potency at D1-Like Dopamine Receptors

Frontiers in Pharmacology, 2020
In recent years, transmembrane voltage has been found to modify agonist potencies at several G protein-coupled receptors (GPCRs). Whereas the voltage sensitivities of the Gαi/o-coupled dopamine D2-like receptors (D2R, D3R, D4R) have previously been ...

DRD2 Deficiency Underlies Pituitary Adenoma Dependent on Escherichia coli Translocation from the Gut

Advanced Science, EarlyView.
Dopamine receptor D2 (DRD2) deficiency disrupts epithelial barrier integrity in both the gut and pituitary gland, facilitating translocation of gut‐derived Escherichia coli into pituitary tissue. Intratumoral E. coli are phagocytosed by microglia, triggering GSDMD‐dependent pyroptosis and HMGB1 release, which subsequently activates MAPK signaling to ...

DOPAMINE AND THE BIOLOGY OF CREATIVITY: LESSONS FROM PARKINSON’S DISEASE

Frontiers in Neurology, 2014
BACKGROUND: Parkinson’s disease (PD) is characterized by reduced flexibility, conceptualization and visuo-spatial abilities. Although these are essential to creativity, case studies show emergence of creativity during PD.

Remimazolam Ameliorates Autistic‐Like Behaviors via Suppression of Ferroptosis in VTA Dopaminergic Neurons in a Mouse Model of ASD

Advanced Science, EarlyView.
The ultra‐short‐acting sedative remimazolam has a sustained therapeutic effect on the core symptoms of VPA‐exposed mice. Remimazolam, a GABA agonist, exerts its therapeutic effects by protecting dopamine neurons in the VTA of VPA‐exposed mice. Meanwhile, ferroptosis is the critical mechanism by which remimazolam protects VTA dopaminergic neurons and ...

Gαi1/3 Is a Novel Regulatory Target for RANKL Signal Transduction and Osteoporosis

Advanced Science, EarlyView.
ABSTRACT Osteoporosis, characterized by progressive bone loss and increased fracture risk, is a growing concern as the population ages. Current treatments, though advanced, remain limited, underscoring the necessity for novel therapeutic targets. Recent studies have shown that the immune system plays a key role in osteoporosis, with osteoclasts driving

Synergistic activation of dopamine D1 and TrkB receptors mediate gain control of synaptic plasticity in the basolateral amygdala. [PDF]

PLoS ONE, 2011
Fear memory formation is thought to require dopamine, brain-derived neurotrophic factor (BDNF) and zinc release in the basolateral amygdala (BLA), as well as the induction of long term potentiation (LTP) in BLA principal neurons.

Amyloid β Instigates Cardiac Neurotrophic Signaling Impairment, Driving Alzheimer's Associated Heart Disease

Advanced Science, EarlyView.
This research identified cardiac amyloid pathology, neurotrophic factor depletion, and reduced myocardial nerve function in a transgenic model of cerebral amyloidosis (Tg2576), Aβ‐challenged cardiomyocytes, and in human AD heart tissue. These findings carry significant diagnostic and therapeutic implications, emphasizing the role of neuro‐signaling ...

Dopamine agonist and tamoxifen combination therapy for a prolactin-secreting pituitary tumor resistant to dopamine agonist monotherapy: Case report and review

Interdisciplinary Neurosurgery, 2020
Background: The majority of prolactin-secreting pituitary macroadenomas are effectively managed with dopamine-agonist therapy alone. Although surgical resection and radiotherapy are second- and third-line treatment options, there remains a paucity of ...

Dopamine agonist-responsive Cushing’s disease

BMJ Case Reports, 2019
A 47-year-old Caucasian man was referred to our clinic with a severe clinical and biochemical phenotype of endogenous hypercortisolism for further evaluation and treatment. In addition to confirming adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome, we found left temporal hemianopsia, massively increased prolactin, increased growth ...
