Here we provide evidence for an alternative approach in which inhibition of the negative regulatory inositol kinase Itpkb in mature T lymphocytes results in enhanced intracellular calcium levels following antigen receptor activation leading to T cell apoptosis.DeletionofItpkb ortreatmentwith Itpkb inhibitors blocksT-cell dependent anti- Itpkb+/+ and Itpkbfl/fl mice wereimmunized intraperitoneal(i.p.) witheither100μlDNP-KLH/ Alum (Calbiochem) at1mg/mltoassess Tcell-dependent antibodyresponses, orwith 100μl Compare & Order ITPKB Proteins from many different species.

ITPKB is also highly expressed in several brain regions related to PD, including the SNpc, striatum, and cerebral cortex . ITPKB is one of three ubiquitously expressed kinases known to phosphorylate inositol-1,4,5-triphosphate (IP 3), an intracellular messenger produced from phosphatidylinositol-4,5-bisphosphate by phospholipase C (23, 24). 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 Mechanistically, we identified that IP4 competes with the NOX4 cofactor NADPH for binding and consequently inhibits NOX4.

“BTK inhibition targets both adaptive and innate drivers of immune-mediated disease,” explained David J. Kuter, MD, DPhil, from Massachusetts General Hospital, during his EHA25 Virtual presentation.

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.

small-molecule inhibitors BAMB-4 and GNF362 are reported to specifically inhibit ITPK isoforms (23–25). Mounting evidence sug - gests that ITPKB is implicated in hematopoiesis. ITPKB is known Figure 1. ITPKB upregulation is associated with cisplatin resistance in diverse cancer cell lines and primary patient samples. Itpkb-deficient B lymphocytes had the phenotypic and functional features of tolerant B lymphocytes and showed enhanced activity of store-operated Ca 2+ channels after B lymphocyte receptor Furthermore, pharmaceutical inhibition of ITPKB displayed synergistic attenuation of tumor growth with cisplatin, suggesting ITPKB as a promising synthetic lethal target for cancer therapeutic intervention to overcome cisplatin resistance. Pharmacological inhibition of ITPKB in mice reduced both LPS-induced tissue swelling and the severity of inflammatory arthritis to a similar extent as that induced by the inhibition of NFAT using 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.
