The safety and efficacy of ibrutinib, an oral inhibitor of Bruton tyrosine kinase, were evaluated with chemoimmunotherapy (CIT) in a multicenter phase 1b study. Patients with relapsed/refractory chronic lymphocytic leukemia received bendamustine and rituximab (BR) or fludarabine, cyclophosphamide, and rituximab (FCR) for up to 6 cycles with daily ibrutinib (420 mg) until progressive disease or ...
During B-cell development in the mouse, Bruton tyrosine kinase (Btk) and the adaptor protein SLP-65 (Src homology 2 [SH2] domain-containing leukocyte protein of 65 kDa) limit the expansion and promote the differentiation of pre-B cells. Btk is thought to mainly function by phosphorylating phospholipase Cgamma2, which is brought into close proximity of Btk by SLP-65. However, this model was rece...
Bruton tyrosine kinase (Btk) is critical for B-cell development. Btk regulates a plethora of signaling proteins, among them nuclear factor-[kappa]B (NF-kappaB). Activation of NF-kappaB is a hallmark of B cells, and NF-kappaB signaling is severely compromised in Btk deficiency. We here present strong evidence indicating that NF-kappaB is required for efficient transcription of the Btk gene. Firs...
The Bruton non-receptor protein-tyrosine kinase (BTK), a deficiency of which leads to X-linked agammaglobulinemia, plays a central role in B cell antigen receptor signaling. Owing to the exclusivity of this enzyme in B cells, the acronym could represent B cell tyrosine kinase. BTK is activated by the Lyn and SYK protein kinases following activation of the B cell receptor. BTK in turn catalyzes ...
