Histamine pharmacology: from Sir Henry Dale to the 21st century

open access: yesBritish Journal of Pharmacology, 2018
Histamine has been one of the most studied substances in medicine, playing a major role in diverse (patho)physiological processes. It elicits its multifaceted modulatory functions by activating four types of GPCRs, designated as H1–4.

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

open access: yes, 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 ...

Bacterial secretion of histamine within the gut influences immune responses within the lung

open access: yesAllergy. European Journal of Allergy and Clinical Immunology, 2019
Histamine is an important immunomodulator influencing both the innate and adaptive immune system. Certain host cells express the histidine decarboxylase enzyme (HDC), which is responsible for catalysing the decarboxylation of histidine to histamine.

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.

H3 histamine receptor-mediated activation of protein kinase calpha inhibits the growth of cholangiocarcinoma in vitro and in vivo [PDF]

open access: yes, 2009
Histamine regulates functions via four receptors (HRH1, HRH2, HRH3, and HRH4). The D-myo-inositol 1,4,5-trisphosphate (IP(3))/Ca(2+)/protein kinase C (PKC)/mitogen-activated protein kinase pathway regulates cholangiocarcinoma growth.
