Histamine Excites Rat Superior Vestibular Nuclear Neurons via Postsynaptic H1 and H2 Receptors in vitro [PDF]

open access: yesNeurosignals, 2012
The superior vestibular nucleus (SVN), which holds a key position in vestibulo-ocular reflexes and nystagmus, receives direct hypothalamic histaminergic innervations.

Function and Role of Histamine H1 Receptor in the Mammalian Heart [PDF]

open access: yes, 2023
Histamine can change the force of cardiac contraction and alter the beating rate in mammals, including humans. However, striking species and regional differences have been observed. Depending on the species and the cardiac region (atrium versus ventricle)

Investigations on neuropeptide Y and histamine receptors by fluorescence-based and radiochemical methods [PDF]

open access: yes, 2011
In the last three decades, a large amount of experimental data (for example Förster resonance energy transfer (FRET) at fluorescently labelled receptors) supported the hypothesis of the dimerization of G-protein-coupled receptors (GPCR), including ...

Novel chalcone-based fluorescent human histamine H 3 receptor ligands as pharmacological tools [PDF]

open access: yes, 2012
Novel fluorescent chalcone-based ligands at human histamine H(3) receptors (hH(3)R) have been designed, synthesized, and characterized. Compounds described are non-imidazole analogs of ciproxifan with a tetralone motif.

Plasticity of histamine H3 receptor expression and binding in the vestibular nuclei after labyrinthectomy in rat [PDF]

open access: yes, 2004
Background: In rat, deafferentation of one labyrinth (unilateral labyrinthectomy) results in a characteristic syndrome of ocular and motor postural disorders (e.g., barrel rotation, circling behavior, and spontaneous nystagmus). Behavioral recovery (e.g.,

Re-sensitization of desensitized histamine H1 receptors in the human skin takes more than 18 hours [PDF]

open access: yes, 2020
Background: It is known since the time of testing histamine on pieces of guinea pig's jejunum that histamine receptors can develop insensitivity. The aim was to find evidence for desensitization of histamine H1 receptors in the human skin in vivo and, if

Typical and Atypical Antipsychotic Drugs Increase Extracellular Histamine Levels in the Rat Medial Prefrontal Cortex: Contribution of Histamine H1 Receptor Blockade

open access: yesFrontiers in Psychiatry, 2012
Atypical antipsychotics such as clozapine and olanzapine have been shown to enhance histamine turnover and this effect has been hypothesized to contribute to their improved therapeutic profile compared to typical antipsychotics.

Perioperative uses of histamine antagonists [PDF]

open access: yes, 1990
Histamine release and adverse pseudoallergic/allergic reactions during the perioperative period occur frequently. The incidence of such reactions is 20%-30% for all grades of severity, 1%-5% for systemic reactions, and 0.1%-0.5% for life-threatening ...

Histamine elicits glutamate release from cultured astrocytes

open access: yesJournal of Pharmacological Sciences, 2018
Astrocytes play key roles in regulating brain homeostasis and neuronal activity. This is, in part, accomplished by the ability of neurotransmitters in the synaptic cleft to bind astrocyte membrane receptors, activating signalling cascades that regulate ...

Histamine and migraine revisited: mechanisms and possible drug targets

open access: yesThe Journal of Headache and Pain, 2019
Objective To review the existing literature on histamine and migraine with a focus on the molecule, its receptors, its use in inducing migraine, and antihistamines in the treatment of migraine. Background Histamine has been known to cause a vascular type
