The brain H3-receptor as a novel therapeutic target for vigilance and sleep-wake disorders. (2007)

Parmentier, Régis, Anaclet, Christelle, Guhennec, Christian, Brousseau, Emmanuel, Bricout, Denis, Giboulot, Thierry, ...

Brain histaminergic neurons play a prominent role in arousal and maintenance of wakefulness (W). H(3)-receptors control the activity of histaminergic neurons through presynaptic autoinhibition. The...

The mouse l-histidine decarboxylase gene: structure and transcriptional regulation by CpG methylation in the promoter region

Suzuki-Ishigaki, Satsuki, Numayama-Tsuruta, Keiko, Kuramasu, Atsuo, Sakurai, Eiko, Makabe, Yoko, Shimura, Sanae, ...

To investigate the regulation of mouse l-histidine decarboxylase (HDC) gene expression, we isolated genomic DNA clones encoding HDC. Structural analysis revealed that the mouse HDC gene was composed...

Enhancement of neutrophil infiltration in histidine decarboxylase-deficient mice

Hirasawa, Noriyasu, Ohtsu, Hiroshi, Watanabe, Takehiko, Ohuchi, Kazuo

The roles of histamine in the anaphylactic increase in vascular permeability and leucocyte infiltration were analysed in an air pouch-type allergic inflammation model in histidine...

Organic cation transporter 3 modulates murine basophil functions by controlling intracellular histamine levels

Schneider, Elke, Machavoine, François, Pléau, Jean-Marie, Bertron, Anne-France, Thurmond, Robin L., Ohtsu, Hiroshi, ...

In this study, we identify the bidirectional organic cation transporter 3 (OCT3/Slc22a3) as the molecule responsible for histamine uptake by murine basophils. We demonstrate that OCT3 participates in...

Defective Angiogenesis in the Inflammatory Granulation Tissue in Histidine Decarboxylase–deficient Mice but not in Mast Cell–deficient Mice

Ghosh, Ajoy Kumar, Hirasawa, Noriyasu, Ohtsu, Hiroshi, Watanabe, Takehiko, Ohuchi, Kazuo

We have analyzed the role of histamine in the angiogenesis of the granulation tissue in histidine decarboxylase–deficient (HDC−/−) mice, mast cell–deficient mice (WBB6F1-W/WV), and their...

Inhibition of histamine-mediated signaling confers significant protection against severe malaria in mouse models of disease

Beghdadi, Walid, Porcherie, Adeline, Schneider, Bradley S., Dubayle, David, Peronet, Roger, Huerre, Michel, ...

From the inoculation of Plasmodium sporozoites via Anopheles mosquito bites to the development of blood-stage parasites, a hallmark of the host response is an inflammatory reaction characterized by...
