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.

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.

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

open access: yesJournal 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.

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

open access: yes, 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).

Histamine and H1-histamine receptors faster venous circulation [PDF]

open access: yesJournal of Cellular and Molecular Medicine, 2011
The study has analysed the action of histamine in the rabbit venous system and evaluated its potential role in contraction during increased venous pressure. We have found that a great variety exists in histamine sensitivity and H(1) -histamine receptor expression in various types of rabbit veins.

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.

Direct imaging of lateral movements of AMPA receptors inside synapses [PDF]

open access: yesEMBO J 22, 18 (15/09/2003) 4656-65, 2007
Trafficking of AMPA receptors in and out of synapses is crucial for synaptic plasticity. Previous studies have focused on the role of endo/exocytosis processes or that of lateral diffusion of extra-synaptic receptors. We have now directly imaged AMPAR movements inside and outside synapses of live neurons using single-molecule fluorescence microscopy ...

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

open access: yes, 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]

open access: yes, 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.

Ligand-guided homology modeling drives identification of novel histamine H3 receptor ligands [PDF]

open access: yes, 2019
In this study, we report a ligand-guided homology modeling approach allowing the analysis of relevant binding site residue conformations and the identification of two novel histamine H3 receptor ligands with binding affinity in the nanomolar range.
