Recent Advances in Molecular Pharmacology of the Histamine Systems: Roles of C-terminal Tails of Histamine Receptors

Journal of Pharmacological Sciences, 2006
.: G-protein-coupled receptors (GPCR) represent a large and diverse superfamily of integral membrane proteins to which histamine receptors belong. Increasing numbers of proteins have been identified to interact with the C-termini of GPCRs.

Histamine elicits glutamate release from cultured astrocytes

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

Journal 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.

Histamine and Histamine H4 Receptor Promotes Osteoclastogenesis in Rheumatoid Arthritis. [PDF]

, 2017
Histamine H4 receptor (H4R) has immune-modulatory and chemotaxic effects in various immune cells. This study aimed to determine the osteoclastogenic role of H4R in rheumatoid arthritis (RA).

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

Frontiers 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.

Targeted therapy with histamine antagonists - New challenges to fight with breast cancer

Journal of Education, Health and Sport, 2022
Breast cancer (BC) is currently the most commonly diagnosed cancer in women. BC is most often derived from the epithelial tissue of the mammary gland and is a global problem due to the steady increase in morbidity and mortality in most countries.

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

, 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.

Histamine stimulates the proliferation of small and large cholangiocytes by activation of both IP3/Ca2+ and cAMP-dependent signaling mechanisms [PDF]

, 2012
Although large cholangiocytes exert their functions by activation of cyclic adenosine 3',5'-monophosphate (cAMP), Ca(2+)-dependent signaling regulates the function of small cholangiocytes. Histamine interacts with four receptors, H1-H4HRs.

Short photoperiod-induced decrease of histamine H3 receptors facilitates activation of hypothalamic neurons in the Siberian Hamster [PDF]

, 2009
Nonhibernating seasonal mammals have adapted to temporal changes in food availability through behavioral and physiological mechanisms to store food and energy during times of predictable plenty and conserve energy during predicted shortage.

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

Journal 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.
