Jefferies CA, Doyle S, Brunner C, Dunne A, Brint E, Wietek C, Walch E, Wirth T, O'Neill LA. BTK was initially shown to be defective in the primary immunodeficiency X-linked agammaglobulinemia (XLA) and is essential both for B cell development and function of mature B cells. BTK is a 76-kDa polypeptide with 659 amino acid residues. However, the role of BTK identified is dependent on cell type investigated, the nature of activating stimuli, the model used (in vivo or in vitro) and the species investigated, i.e. Enhanced expression of Bruton's tyrosine kinase in B cells drives systemic autoimmunity by disrupting T cell homeostasis.

Autoantigen can promote progression to a more aggressive TCL1 leukemia by selecting variants with enhanced B-cell receptor signaling. 2006;24:22–7. SHP1 acts downstream of CD22, a lectin molecule, and the glycoprotein CD5, both of which are on the B cell surface and function as negative regulators of BCR signaling. As a result, there is currently a considerable interest in BTK inhibition as an anti-cancer therapy, not only in B cell malignancies but also in solid tumors. Neutropenia in X-linked agammaglobulinemia. 2015;112:E966–72. 2011;43:830–7. These involve B cell-intrinsic signaling pathways central to cellular survival, proliferation or retention in supportive lymphoid niches. In contrast, inhibitory Fc-receptors (FcγRIIB) containing ITIM domains recruit phosphatases and reduce BTK activation (Fig. Lenz G, Davis RE, Ngo VN, Lam L, George TC, Wright GW, Dave SS, Zhao H, Xu W, Rosenwald A, et al. BTK-deficient mice have only a mild pre-B cell defect, whereby pre-B cells show impaired developmental progression into immature B-cells [9, 10]. BTK and SLP65 or BTK and TEC [57, 93, 94]. 2017;12:e0171221. Terms and Conditions, Blood. In this context, it is of note that mice expressing the constitutively active BTK mutant E41K fail to form GCs [111, 112], whereas overexpression of wild-type BTK induces spontaneous GC formation [113, 114]. These include other TEC-family kinases (ITK, BMX, TEC), as well as epidermal growth factor receptor (EGFR), T-cell X chromosome kinase (TXK) and Janus Kinase 3 (JAK3) [12, 185, 207]. The gene contains 19 exons and the open reading frame has 1977 nucleotides. 2016;16:431–46. Immunity. Ibrutinib in previously treated Waldenstrom's macroglobulinemia. 2010;40:2643–54.

Bruton's Tyrosine Kinase Inhibitors Prevent Therapeutic Escape in Breast Cancer Cells. As a result BTK has lost its kinase activity, but Y551 phosphorylation by SYK is not affected. Part of the toxicities and side effects of ibrutinib can be explained by its non-specific nature: ibrutinib is not an exclusive inhibitor of BTK and off-target inhibition includes kinases that contain a cysteine residue aligning with Cys-481 in BTK. the L528 W mutation in the kinase domain, which is associated with resistance to BTK inhibition in CLL (described below), and an in-frame deletion that also alters this amino acid and the adjacent C527. a Schematic overview of the protein structure of BTK and other TEC kinase family members.

Furthermore, BTK inhibitors also exhibit anti-thrombotic properties that may be desirable in the context of the increased risk of thromboembolic complications in cancer patients. The Bruton tyrosine kinase inhibitor PCI-32765 thwarts chronic lymphocytic leukemia cell survival and tissue homing in vitro and in vivo. J Exp Med. In this context, it was shown that treatment of primary CLL samples with histone deacetylase (HDAC) inhibitors resulted in increased expression of these miRs and decreased BTK protein. Nature. Another important branching point is induced more upstream in the BCR signaling cascade: in addition to BTK, PIP3 also interacts with PH-domain of AKT, resulting in its recruitment to the plasma membrane. Burger JA, Tedeschi A, Barr PM, Robak T, Owen C, Ghia P, Bairey O, Hillmen P, Bartlett NL, Li J, et al. The importance of the oncogenic AKT/PI3K pathway in GCB-DLBCL is evident from the finding that in ~ 55% of patients the tumor suppressor phosphatase and tensin homolog (PTEN), a negative regulator of PI3K, is inactivated. Bruton's tyrosine kinase (BTK) is a key component of the B-cell receptor (BCR) signaling pathway and plays an essential role in B-cell maturation and lymphomagenesis. Pucci F, Garris C, Lai CP, Newton A, Pfirschke C, Engblom C, Alvarez D, Sprachman M, Evavold C, Magnuson A, et al. For example, the FcγRIIB is an inhibitory receptor that is exclusively expressed on B cells [60]. Hereby, the adaptor molecule Cbl-interacting protein of 85 kD (CIN85) functions to oligomerize SLP65 and assembles intracellular signaling clusters for B cell activation [46]. Bolland S, Ravetch JV. Importantly, both in CLL and MCL ibrutinib treatment induces a redistribution lymphocytosis, a transient rise of leukemic cells in the circulation and a concomitant rapid reduction of these cells at the affected tissue sites. 2003;423:452–6. Oncotarget. Analysis of the coding genome of diffuse large B-cell lymphoma. Consistent with a role of NF-кB downstream of the BCR (Fig. 2014;74(19)(suppl). Interestingly SLP65-deficient mice, which also have a mild arrest at the pre-B cell stage, develop pre-B cell leukemia resembling pre-B ALL in humans [93, 94]. Importantly, phosphorylation of AKT is positively regulated by BTK [56]. Recently, Bruton Tyrosine Kinase (BTK) has emerged as an interesting candidate. Damle RN, Wasil T, Fais F, Ghiotto F, Valetto A, Allen SL, Buchbinder A, Budman D, Dittmar K, Kolitz J, et al. PubMed  Clin Immunol. 2010;115:3118–27. Shinohara M, Koga T, Okamoto K, Sakaguchi S, Arai K, Yasuda H, Takai T, Kodama T, Morio T, Geha RS, et al. The genomic landscape of Waldenstrom macroglobulinemia is characterized by highly recurring MYD88 and WHIM-like CXCR4 mutations, and small somatic deletions associated with B-cell lymphomagenesis. Efficacy of ibrutinib in a clinical study was first reported in patients with various relapsed/refractory B-cell malignancies, showing clinical safety and promising durable objective responses particularly in CLL and MCL [186]. Btk regulates macrophage polarization in response to lipopolysaccharide. BTK was initially shown to be mutated in the primary immunodeficiency X-linked agammaglobulinemia (XLA) and is essential at various stages of B lymphocyte development [3, 4]. Shortly after its discovery, BTK was placed in the signal transduction pathway downstream of the B cell antigen receptor (BCR). Blood. Direct stimulation of Bruton's tyrosine kinase by G(q)-protein alpha-subunit. 2016;29:161–8. Because ibrutinib is generally well tolerated and shows durable single-agent efficacy, it was rapidly approved for first-line treatment of patients with CLL in 2016. Hendriks RW, Middendorp S. The pre-BCR checkpoint as a cell-autonomous proliferation switch. Human B1 cells in umbilical cord and adult peripheral blood express the novel phenotype CD20+ CD27+ CD43+ CD70. DAG mediates activation of protein kinase Cβ (PKCβ), which induces activation of several members of the MAPK family, including extracellular signal-regulated kinases 1 and 2 (ERK1/ERK2) and other MAPK targets, such as Jun N-terminal kinase (JNK), p38, and NF-кB pathway components [52] (Fig. EMBO J. Finally, BCR and TLR are thought to be key activation pathways in marginal zone lymphoma (MZL), often associated with chronic inflammation in the context of autoimmunity and/or infection [182], implicating BTK as a potential target. Ibrutinib antagonizes rituximab-dependent NK cell-mediated cytotoxicity. These pre-clinical findings have led to the initiation of several early phase I/II clinical trials in which BTK inhibition monotherapy is evaluated in advanced ovarian, colorectal, prostate and brain cancer patients(Table 3).
