Platelet-Activating Factor-Induced Reduction in Contact Hypersensitivity Responses Is Mediated by Mast Cells via Cyclooxygenase-2-Dependent Mechanisms [PDF]

, 2018
Platelet-activating factor (PAF) stimulates numerous cell types via activation of the G protein-coupled PAF receptor (PAFR). PAFR activation not only induces acute proinflammatory responses, but it also induces delayed systemic immunosuppressive effects ...

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

Frontiers 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.

In Vivo Anti-Inflammatory Effect of H1 Antihistamines in Allergic Rhinitis: A Randomized Clinical Trial

Balkan Medical Journal, 2015
Background: Allergic rhinitis is characterized by a chronic inflammation of nasal mucosa and represents a risk factor for asthma occurrence. H1 antihistamines reduce the symptoms of rhinitis, but some compounds may have anti-inflammatory properties ...

Histamine receptors (version 2019.4) in the IUPHAR/BPS Guide to Pharmacology Database [PDF]

, 2019
Histamine receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Histamine Receptors [75, 163]) are activated by the endogenous ligand histamine. Marked species differences exist between histamine receptor orthologues [75]. The human and rat

Pharmacological study of ebastine, a novel histamine H1-receptor antagonist.

Folia Pharmacologica Japonica, 1994
The anti-allergic activity of ebastine, a novel antihistamine, was assessed in comparison with several antihistamines. 1) Orally administered ebastine dose-dependently inhibited 7-day homologous passive cutaneous anaphylaxis (PCA), experimental allergic rhinitis and experimental asthma in guinea pigs or rats (ED50-values were 2.17, 0.29 and 0.35 mg/kg,

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

Journal 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
