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

Highly potent, selective acylguanidine-type histamine H2 receptor agonists: synthesis and structure-activity relationships [PDF]

open access: yes, 2008
Potent and selective histamine H2 receptor (H2R) agonists are valuable pharmacological tools and might be of therapeutic value as drugs, for example in the treatment of severe congestive heart failure.

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 ...

On the Mechanisms Underlying Histamine Induction of Gastric Mucosal Lesions in Rats With Partial Gastric Vascular Occlusion

open access: yesJournal of Pharmacological Sciences, 2003
Although it is well known that histamine induces gastric mucosal lesions in laboratory animals, the fundamental mechanisms remain unclear. In order to further analyze the vascular mechanisms underlying histamine-induced lesions, a new model was developed

Structure of the human histamine H1 receptor gene [PDF]

open access: yesBiochemical Journal, 1998
Histamine H1 receptor expression has been reported to change in disorders such as allergic rhinitis, autoimmune myocarditis, rheumatoid arthritis and atherosclerosis. Here we report the isolation and characterization of genomic clones containing the 5´ flanking (regulatory) region of the human histamine H1 receptor gene. An intron of approx. 5.8 kb was

Histamine: A Mediator of Intestinal Disorders—A Review

open access: yesMetabolites, 2022
Within the gastrointestinal tract, histamine is present at relatively high concentrations, especially during inflammatory processes. Histamine is a biogenic amine with numerous effects on many cell types, mediated by the activation of its four different ...

The Histamine H4 Receptor: From Orphan to the Clinic

open access: yesFrontiers in Pharmacology, 2015
The histamine H4 receptor (H4R) was first noted as a sequence in genomic databases that had features of a G-protein coupled receptor. This putative receptor was found to bind histamine consistent with its homology to other histamine receptors and thus ...

Histamine H1 Receptor Contributes to Vestibular Compensation [PDF]

open access: yesThe Journal of Neuroscience, 2018
Vestibular compensation is responsible for the spontaneous recovery of postural, locomotor, and oculomotor dysfunctions in patients with peripheral vestibular lesion or posterior circulation stroke. Mechanism investigation of vestibular compensation is of great importance in both facilitating recovery of vestibular function and understanding the ...

Differential photoaffinity labelling of serotonin-S2 receptors and histamine-H1 receptors using 7-azidoketanserin [PDF]

open access: yes, 1985
7-Azidoketanserin, a potent photoaffinity probe for serotonin-S2 receptors was shown to irreversibly photoinactivate histamine-H1receptors as well. The photolabelling of H1-receptors could be prevented by several selective histamine-H1 antagonists.

H1 and H2 Histamine Receptors Are Absent on Langerhans Cells and Present on Dermal Dendritic Cells [PDF]

open access: yes, 2003
Human monocyte-derived dendritic cells (MoDC) have both histamine H1 and H2 receptors and can induce CD86 expression by histamine. Nevertheless, it has not been reported whether human epidermal Langerhans cells (LC) have histamine receptors or not.
