In this study, we employed genetic and pharmacological approaches to inhibit Itpkb signaling as a means of controlling graft-versus-host disease (GVHD). Murine-

Itpkb pathway inhibition increases intracellular Ca2+, induces apoptosis of activated T cells, and can control T-cell-mediated autoimmunity. In this study, we employed genetic and pharmacological approaches to inhibit Itpkb signaling as a means of controlling graft-versus-host disease (GVHD). ITPKB produces Ins(1,3,4,5)P4, which does not gate the inositol trisphosphate receptor. The enzyme specifically phosphorylates the 1,4,5 isomer of IP 3 .

ITPKB produces Ins (1,3,4,5)P 4, which does not gate the inositol trisphosphate receptor. Targeting ITPKB with shRNA or its small molecule inhibitor resulted in attenuation of NOX4 activity, imbalanced redox status, and sensitized cancer cells to cisplatin treatment in patient-derived xenografts. The IUPHAR/BPS Guide to Pharmacology. IP 3 kinase B - Inositol 1,4,5-trisphosphate 3-kinases. Detailed annotation on the structure, function, physiology, pharmacology and clinical relevance of drug targets. 2019-05-13 · The small-molecule inhibitors BAMB-4 and GNF362 are reported to specifically inhibit ITPK isoforms (23 – 25). Mounting evidence suggests that ITPKB is implicated in hematopoiesis.

GNF362 is a selective, potent, and orally bioavailable inhibitor of inositol trisphosphate 3' kinase B (Itpkb) with an IC50 of 9 nM. GNF362 also inhibits Itpka and

Targeting ITPKB with shRNA or its small-molecule inhibitor resulted in attenuation of NOX4 activity, imbalanced redox status, and sensitized cancer cells to cisplatin treatment in patient-derived xenografts. Patients with persistent or chronic ITP were more likely to respond to fostamatinib, a tyrosine kinase inhibitor that was approved by the FDA in 2018 for the treatment of chronic ITP, if it was initiated as second-line therapy, rather than as third line or beyond, according to an analysis of three phase III trials.

“Itpkb pathway inhibition increases intracellular Ca 2+, induces apoptosis of activated T cells, and can control T-cell–mediated autoimmunity,” they continued. Thus, Dr Thangavelu and co-investigators conducted a study in which they used genetic and pharmacologic methods to inhibit Itpkb signaling as a means of controlling GVHD.

GNF362 also inhibits Itpka and Itpkc with IC50 values of 20 nM and 19 nM, respectively. Using Itpkb conditional knockout mice and LMW Itpkb inhibitors these studies reveal that Itpkb through its product IP4 inhibits the Orai1/Stim1 calcium channel on lymphocytes. Pharmacological inhibition or genetic deletion of Itpkb results in elevated intracellular Ca2+ and induction of FasL and Bim resulting in T cell apoptosis.

Professor Stéphane Schurmans, director of the GIGA Functional Genetics Laboratory at the University of Liège, reveals the results of his work in a study published in Brain. Future studies with sub-optimal Akt/mTOR inhibitor concentrations not affecting WT thymocytes but still reversing the Itpkb-/-phenotype, with complex genetic models and with inhibitors of β-selection effectors unaffected by Itpkb will be needed to more conclusively distinguish between specific causative roles for the Akt/mTORC1 and metabolic hyperactivity and mere remaining sensitivity of Using Itpkb conditional knockout mice and LMW Itpkb inhibitors these studies reveal that Itpkb through its product IP4 inhibits the Orai1/Stim1 calcium channel on lymphocytes. Pharmacological inhibition or genetic deletion of Itpkb results in elevated intracellular Ca²⁺ and induction of FasL and Bim resulting in T cell apoptosis. 2005-04-26 · cytoplasm, cytosol, nucleus, inositol hexakisphosphate kinase activity, inositol-1,4,5-trisphosphate 3-kinase activity, kinase activity, cellular response to calcium ion, inositol phosphate biosynthetic process, inositol phosphate metabolic process, inositol trisphosphate metabolic process Does Itpkb Inhibition have Therapeutic Potential in Human Diseases? The T and B cell defects in germline Itpkb −/− mice sparked efforts to develop specific and selective Itpkb small-molecule inhibitors as potential therapeutics for autoimmune disorders or transplant rejection, reviewed in detail in Ref. (8, 149). Moreover, Akt inhibition reduced RMA/S-induced ItpkB −/− NK cell hyperdegranulation to inhibitor-untreated WT NK cell levels (22.3% vs 20.7%; Figure 7A-B). The similar abilities of cell-permeable IP 4 , PI3K, or Akt inhibitors to reverse the hyperdegranulation of ItpkB −/− NK cells are consistent with a model in which IP 4 limits NK cell degranulation by antagonizing NKR-induced Akt recruitment by PI3K/PIP 3 .
