A human histamine H1 receptor gene lacking introns was isolated by screening a human genomic library with a bovine histamine H1 receptor probe. The deduced protein of 487 amino acids showed characteristic properties of G-protein-coupled receptors. The coding region was subcloned into the expression vector pSVL (Pharmacia), and the resulting construct transfected into COS-7 cells. Binding studies with [3H]pyrilamine on membranes from transfected cells revealed saturable specific binding with a KD of 1.2 nM and a Bmax of 3400 fmol/mg protein. Binding affinities of histamine and known histamine antagonists were similar to those for histamine H1 receptors in guinea-pig cerebellum. In transfected COS-7 cells, histamine induced inositol phosphate formation, that was inhibitable by pyrilamine ...

Histamine is a ubiquitous messenger molecule released from mast cells, enterochromaffin-like cells, and neurons. Its various actions are mediated by histamine receptors H1, H2, H3 and H4. This gene encodes one of the histamine receptors (H3) which belongs to the family 1 of G protein-coupled receptors. It is an integral membrane protein and can regulate neurotransmitter release. This receptor can also increase voltage-dependent calcium current in smooth muscles and innervates the blood vessels and the heart in cardiovascular system. [provided by RefSeq, Jul 2008]
Histamine is a ubiquitous messenger molecule released from mast cells, enterochromaffin-like cells, and neurons. Its various actions are mediated by histamine receptors H1, H2, H3 and H4. This gene was thought to be intronless until recently. The protein encoded by this gene is an integral membrane protein and belongs to the G protein-coupled receptor superfamily. It mediates the contraction of smooth muscles, the increase in capillary permeability due to contraction of terminal venules, the release of catecholamine from adrenal medulla, and neurotransmission in the central nervous system. Multiple alternatively spliced variants, encoding the same protein, have been identified ...
H2 receptors are positively coupled to adenylate cyclase via Gs. It is a potent stimulant of cAMP production, which leads to activation of protein kinase A. PKA functions to phosphorylate certain proteins, affecting their activity. The drug betazole is an example of a histamine H2 receptor agonist. Histamine is a ubiquitous messenger molecule released from mast cells, enterochromaffin-like cells, and neurons. Its various actions are mediated by histamine receptors H1, H2, H3 and H4. The histamine receptor H2 belongs to the rhodopsin-like family of G protein-coupled receptors. It is an integral membrane protein and stimulates gastric acid secretion. It also regulates gastrointestinal motility and intestinal secretion and is thought to be involved in regulating cell growth and differentiation. Histamine H2 receptors are expressed in the following tissues: Peripheral tissues Gastric parietal cells (oxyntic cells) Vascular smooth muscle Neutrophils Mast cells Heart Uterus Central nervous system ...
TY - JOUR. T1 - Evaluation of in vivo selective binding of [11C]doxepin to histamine H1 receptors in five animal species. AU - Ishiwata, Kiichi. AU - Kawamura, Kazunori. AU - Wang, Wei Fang.

N2 - The specific binding of [11C]doxepin, which has been used as a radioligand for mapping histamine H1 receptors in human brain by positron emission tomography, was evaluated in five animal species. In mice the [11C]doxepin uptake was reduced by treatment with cold doxepin and two H1 receptor antagonists, but not with H2/H3 antagonists. The specific binding evaluated with treatment with (+)-chlorpheniramine (H1 antagonist) was in the range of 10-30% in mouse, rat, rabbit, and monkey, but was not detected in guinea pig..

Residues in the second extracellular loop (e2) play a role in ligand binding in certain aminergic G protein coupled receptors (GPCRs). N-[3-(1H-Imidazol-4-yl)propyl)]guanidines and N G-acylated derivatives are more efficacious and potent agonists at fusion proteins of the guinea pig histamine H2 receptor and the short splice variant of Gsα, GsαS (gpH2R-GsαS) than at the human isoform (hH2R-GsαS). To elucidate the structural basis for this species-selectivity, we generated a mutant hH2R-GsαS fusion protein with the four e2 residues differing in both species isoforms mutated into the gpH2R sequence, and a reverse mutant of the gpH2R-GsαS with the corresponding mutations into the human species. In a steady-state GTPase activity assay, efficacies and potencies of guanidine-type agonists were similar at mutant and wild-type receptors indicating that e2 does not contribute to the species-selectivity. In several class 1 GPCRs, amino acids in the vicinity of a highly conserved cysteine in e2 ...

The study from Leary et al. (3) intriguingly reports that histamine H2 receptor antagonists (H2RAs) prevent the onset of CHF in a cohort from the MESA study (Multi-Ethnic Study of Atherosclerosis). This is definitively demonstrated by a prospective, observational, and longitudinal study, which is very difficult to perform but provides better evidence than cross-sectional or retrospective analyses like those used in our previous study (10). The authors prospectively followed the residents of 6 U.S. communities for 10 years and observed the onset of CVD in normal subjects who did or did not use blockers of histamine H2 receptors. In our previous paper (10), we reported that blockers of histamine H2 receptors are effective for CHF patients in a retrospective cohort study and a prospective randomized study.. These 2 studies (i.e., the present study and ours) appear to be similar, but that is not the case because prevention is the action undertaken before the onset of events and treatment is ...

TY - JOUR. T1 - Regulation of interleukin-10 secretion by histamine in TH2 cells and splenocytes. AU - Osna, Natalia. AU - Elliott, Kathleen. AU - Khan, Manzoor M.. PY - 2001/3/15. Y1 - 2001/3/15. N2 - Interleukin-10 is a potent suppressive factor that down-regulates cellular immune response via inhibition of the production of TH1 cytokines. Histamine shifts the TH1/TH2 balance from TH1 to TH2 cytokines making the effects of histamine on IL-10 secretion an important factor in this switch. This study was designed to assess the role of histamine in the regulation of IL-10 production and the involvement of PKA and STAT factors in this process. TH2 cells (D10.G4.1) and AKR/j splenocytes were pretreated with histamine at a concentration range of 10-8-10-5 M for 1 h and then activated with PMA + ionomycin or anti-CD3 for 24 h. The supernatants were collected and tested for IL-10 content by ELISA. Histamine stimulated IL-10 production in TH2 cells in a dose-dependent manner that was reversed by both ...

Histamine: youve probably heard of it, especially if you suffer from allergies. But even if you dont, they are something you should be informed about. They could be in your food, and you could be intolerant to them. But what is it exactly? And what does it do? Technically speaking, histamine is a neurotransmitter, me
Next are Enzymes, which are a MUST especially for leaky gut. Histamine intolerant people need help breaking down protein in the body so it does not stay in the intestines fermenting and rotting giving off bacteria and histamine to seep out those holes in your intestinal wall back into your bloodstream. The GOLD standard in enzymes is Enzymedica brand. Start out with their Digest Gold which is a broad spectrum enzyme including several enzymes to break down protein and carbs. Then add in Vira Stop, an enzyme formula that concentrates wholly on the break down of protein. You will need to continue to take both. Start out first, with the Digest Gold taking one capsule prior to each meal. If you experience die off symptoms and you probably will, start slowly and take one before only one meal per day, then slowly work up to two meals, then three and then before snacks and meals.
