Additionally, this kind of tyrosine kinase plays a crucial role in B cell maturation as well as mast cell activation through the high-affinity IgE receptor. In multiple myeloma (MM), a malignancy of plasma cells in the bone marrow, BTK was shown to be overexpressed, whereby BTK activated AKT signaling, leading to down-regulation of P27 expression and upregulation of key stemness genes [179, 180]. Involvement of Bruton's tyrosine kinase in FcepsilonRI-dependent mast cell degranulation and cytokine production. Blood. 2012;120:1877–87. Secchiero P, Voltan R, Rimondi E, Melloni E, Athanasakis E, Tisato V, Gallo S, Rigolin GM, Zauli G. The gamma-secretase inhibitors enhance the anti-leukemic activity of ibrutinib in B-CLL cells. SLP65 serves as a scaffold for various signaling molecules, including BTK and its substrate PLCγ2 [47,48,49,50]. Importantly, the overall response rate was ~ 71%, independent of clinical or genomic risk factors. Protein tyrosine kinase (PTK) is a series of enzyme that can transfer a phosphate group from ATP to a protein in a cell [], which acts as a important role in the genesis of cancer through abnormal transduction [48, 49].PTKs could be classified into 2 families: receptor tyrosine kinase (RTKs) and non-receptor tyrosine kinase (NRTKs Ibrutinib treatment improves T cell number and function in CLL patients. 2003;4:849–56. Function of Bruton's tyrosine kinase during B cell development is partially independent of its catalytic activity. CXCR4): upon chemokine binding to the extracellular domain Gα and Gβy subunits can independently activate PI3K, which results in activation of BTK, AKT and MAPK-dependent pathways.

Part of Walter HS, Rule SA, Dyer MJ, Karlin L, Jones C, Cazin B, Quittet P, Shah N, Hutchinson CV, Honda H, et al. 2018;27:31–42. First, BTK is phosphorylated at position Y551 in the kinase domain by SYK or SRC family kinases [30]. 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. Pathogen-specific B-cell receptors drive chronic lymphocytic leukemia by light-chain-dependent cross-reaction with autoantigens. Bruton's Tyrosine Kinase drug trial offers cancer hope. 1995;3:283–99. These findings explain why in contrast to ibrutinib, treatment with acalabrutinib was not associated with major bleeding events [12]. Whereas one study indicated an M2-skewing of BTK-deficient macrophages [230], recently in a pancreatic cancer mouse model an M1-skewing of intratumoral macrophages was found following ibrutinib treatment [231]. In particular, the orally administered BTK inhibitor ibrutinib, which forms a covalent bond with a cysteine residue in the BTK active site, was also approved for first-line treatment of patients with chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL) in 2016 [13].

Privacy Nature. 2011;144:646–74. Bruton’s tyrosine kinase is required for activation of IkappaB kinase and nuclear factor kappaB in response to B cell receptor engagement. Three year follow-up of ibrutinib-treated CLL patients showed that prolonged treatment was associated with improvement in response quality (the ORR increased to > 90%) and durable remission, while toxicity including cytopenia, fatigue, and infection diminished. 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. 2011;15:1003–21. Antigens binding to CLL BCRs include self-antigens, such as non-muscle myosin IIA, vimentin, apoptotic cells and oxidized low-density lipoprotein [131,132,133,134,135,136], as well as foreign antigens (bacterial polysaccharides and β-(1,6)-glucan, a major antigenic determinant on fungi [132,133,134,135,136,137]); Interestingly, evidence was provided in mice that pathogens may drive CLL pathogenesis by selecting and expanding pathogen-specific B cells that cross-react with self-antigens [138]; (iii) CLL cells were reported to display cell-autonomous Ca2+ mobilization in the absence of exogenous ligands, by virtue of recognizing a single conserved BCR-internal epitope in the IGHV second framework region [139]; very recently, it was found that the internal epitopes recognized by CLL BCRs from distinct subgroups are different [140]. Cell. As a result BTK has lost its kinase activity, but Y551 phosphorylation by SYK is not affected. Structures of human Bruton's tyrosine kinase in active and inactive conformations suggest a mechanism of activation for TEC family kinases. 2011;475:101–5. 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].

Vav3 modulates B cell receptor responses by regulating phosphoinositide 3-kinase activation. The immunoglobulin tail tyrosine motif upgrades memory-type BCRs by incorporating a Grb2-Btk signalling module. Therefore, ibrutinib apparently works by a dual mechanism, by inhibiting intrinsic B cell signaling pathways to compromise their proliferation and survival as well as by disrupting tumor-microenvironment interactions. In addition, BTK mediated signaling events are regulated by various phosphatases that can be recruited to the cell membrane, following crosslinking of inhibitory receptors, e.g., FcγRIIB that is exclusively expressed on B cells and signals upon immune complex binding. Of further relevance in the context of the tumor microenvironment is the polarization status of macrophages, with M1 macrophages displaying a pro-inflammatory anti-tumor phenotype and M2 macrophages being immunosuppressive [22].
