Recombinant Human Histamine H2 receptor (HRH2)

1. Pharmacological or genetic modulations of H2 and H4 HRs (H2R and H4R) not only suppressed gefitinib-induced cytostasis and differentiation of AML cells but also blocked EGFR and ERK1/2 inhibition in MDA-MB-231 cells PMID: 27180173

5. upregulated on T regs following seasonal pollen exposure; allergen immunotherapy had no impact on the expression PMID: 24980224
6. The inhibitory effects of histamine on reactive oxygen species production in whole blood phagocytes are caused by H2R rather than H4R histamine receptors. PMID: 24530738
7. HR signaling through cyclic AMP and exchange protein directly activated by cyclic AMP was required for the histamine effect on LPS-induced monocyte-derived dendritic cells responses PMID: 23465664
8. rs2607474 GG homozygote confers a significantly increased risk for age- and inflammation-related DAPK and CDH1 methylation in gastric epithelium. PMID: 23280118
9. HR2 receptor is involved in histamine-induced GDF-15 expression. PMID: 22975449
10. The results suggest that HRH2 -1018 GG homozygote is a risk factor for the severity of gastric mucosal atrophy under the influence of H. pylori infection, especially in older subjects. PMID: 22720301
11. 1018 GG homozygosity of HRH2 may be associated with the severity of gastric mucosal atrophy PMID: 22615049
12. Excitation of dentate nucleus neurons by histamine suggests that initiation and planning of movement is modulated by histaminergic projections. PMID: 21683759
13. GRK2 induces desensitization of H2R through a phosphorylation-independent and RGS-dependent mechanism PMID: 21705320
14. Results describe the interactions between human H2 receptor and its agonists. PMID: 21212009
15. expression of H(2) during nicotinamide-induced differentiation of human amniotic epithelial cells into pancreatic beta-like cells may define a time-point, indicating involvement of histamine at the earlier stages PMID: 20012462
16. histamine up-regulates LOX-1 expression via the H2 receptor in THP-1 monocytes PMID: 11728449
17. Stimulation of phosphodiesterase IV is mediated by the H2 receptor and related to intracellular levels of cAMP. PMID: 12824943
18. Data show that the rapid and prolonged modulation of cell surface histamine H2 receptor levels by histamine was regulated solely via internalization. PMID: 14523557
19. significant differences in H2 receptor expression in different vascular cell types might play a critical role in histamine induced cellular responses PMID: 15167968
20. human mast cells constitutively express primarily H2 and H4 receptors and that H2 receptors are functionally linked to cellular processes. PMID: 15191551
21. Involvement of histamine H2 receptors in the histamine induced ets-1 expression in melanoma cells PMID: 15848191
22. The equilibrium between receptor endocytosis and recycling is altered before H2R upregulation, probably via suppressing H2R degradation. PMID: 15961859
23. histamine exerts both a proproliferative and a proangiogenic effect via H2/H4 receptor activation, mediated by increasing COX-2-related PGE2 production in COX-2-expressing colon cancer cells PMID: 16203768
24. The point mutation Cys-17 to Tyr-17 in the human histamine H2 receptor results in the formation of an H-bond between Tyr-17 and Asp-271 , favoring the stabilization of an active receptor conformation. PMID: 17347323
25. HRH2 trafficking was analyzed by examination of the roles of arrestin, dynamin, and clathrin on HRH2 internalization. PMID: 18617631
26. These results suggest that the agonist-induced H2R internalization and ERK1/2 activation are partially dynamin-dependent. Furthermore, ERK1/2 activation via H2R is likely dependent of the endocytotic process rather than dynamin itself. PMID: 18691388
27. role in allergy, autoimmunity, graft rejection, malignancy PMID: 18802338
28. H2r exposure to an agonist caused desensitization controlled by H2r phosphorylation via GRK2 and GRK3. PMID: 11641433
29. Histamine H2 receptors regulate intracellular Ca2+ levels exclusively by activation of nonselective cation channels, an effect which is inhibited via specific activation of protein kinase C isoform. PMID: 11466390
