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 ...

Increased Sensitivity of Mice Lacking Extrasynaptic δ-Containing GABAA Receptors to Histamine Receptor 3 Antagonists

open access: yesFrontiers in Pharmacology, 2020
Histamine/gamma-aminobutyric acid (GABA) neurons of posterior hypothalamus send wide projections to many brain areas and participate in stabilizing the wake state.

Histamine Produced by Gram-Negative Bacteria Impairs Neutrophil’s Antimicrobial Response by Engaging the Histamine 2 Receptor

open access: yesJournal of Innate Immunity, 2022
We found that histamine (10−9 M) did not have any effect on the in vitro capture of Escherichia coli by neutrophils but accelerated its intracellular killing.

The Affinity of Histamine for Gq Protein-Coupled Histamine H1-Receptors Is Predominantly Regulated by Their Internalization in Human Astrocytoma Cells

open access: yesJournal of Pharmacological Sciences, 2012
We examined the regulatory mechanisms of the affinity of Gq protein-coupled histamine H1-receptors for histamine after histamine pretreatment in intact human U373 MG astrocytoma cells.

Differential expression of histamine receptors in the bladder wall tissues of patients with bladder pain syndrome/interstitial cystitis – significance in the responsiveness to antihistamine treatment and disease symptoms

open access: yesBMC Urology, 2019
Background Activation of mast cells plays an important role in the pathogenesis of bladder pain syndrome/interstitial cystitis (BPS/IC). Histamine, a mast cell-derived mediators, induced inflammation and hypersensitivity of the bladder. The present study

Histamine upregulates the expression of histamine receptors and increases the neuroprotective effect of astrocytes

open access: yesJournal of Neuroinflammation, 2018
Background Astrocytes have attracted increasing attention over recent decades for their role in neuroinflammation. Histamine, a major aminergic brain neurotransmitter, has an important influence on the main activities of astrocytes, such as ion ...

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

Efficacy of the Multi-Target Compound E153 in Relieving Pain and Pruritus of Different Origins

open access: yesPharmaceuticals, 2023
Itch and pain are closely related but distinct sensations that share largely overlapping mediators and receptors. We hypothesized that the novel, multi-target compound E153 has the potential to attenuate pain and pruritus of different origins.

Delineating the role of histamine-1- and -4-receptors in a mouse model of Th2-dependent antigen-specific skin inflammation. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: Histamine drives pruritus in allergic skin diseases which clinically constitutes a most disruptive symptom. Skin pathology in allergic skin diseases is crucially influenced by different T-helper subsets. However, the contribution of different
