CLL: chronic lymphocytic leukemia PR: pityriasis rosea EGFR: epidermal growth factor receptor PDGFR: platelet-derived growth factor receptor I brutinib, a Bruton tyrosine kinase inhibitor, is a new oral agent approved for the treatment of chronic lymphocytic leukemia (CLL). Ibrutinib is well-tolerated, with the majority of its adverse events within grade 1 or 2 severity. The most common nonhema...
MicroRNAs have been shown to be critical for a number of aspects of immune system regulation and function. Here, we have examined the role of microRNAs in terminal B cell differentiation by analyzing Cd19-Cre(ki/+) Dicer1(fl/fl) mice. We found that in the absence of Dicer, the transitional and marginal zone (MZ) B cell compartments were overrepresented and follicular (FO) B cell generation was ...
Non-Hodgkin's lymphomas (NHL) are a heterogeneous group of lymphoproliferative disorders originating in B lymphocytes, T lymphocytes, or natural killer cells. Mantle cell lymphoma (MCL) accounts for approximately 6% of all newly diagnosed NHL cases. Radiation therapy with or without systemic therapy is a reasonable approach for the few patients who present with early-stage disease. Rituximab-ba...
The risk of central nervous system (CNS) dissemination in mantle cell lymphoma (MCL) is low and occurs late in the course of the disease. However, prognosis in such cases remains extremely poor despite high-dose antimetabolite chemotherapy. Among novel drugs used to treat relapsing MCL patients, ibrutinib, an oral inhibitor of Bruton tyrosine kinase, shows great promise. Here we report the clin...
We analyzed the cause of agammaglobulinemia in a girl whose father had been diagnosed as having X-linked agammaglobulinemia (XLA). Flow cytometric analysis revealed the lack of peripheral B cells with the block of B-cell differentiation in the stages between pro-B cells and pre-B cells in the bone marrow, and the defect of the Bruton tyrosine kinase (BTK) expression on monocytes. We found a BTK...
IgA Fc receptors (Fc alphaR) can mediate a variety of inflammatory responses. It has been demonstrated that the FcRgamma subunit is critical in mediating signaling through Fc alphaR. We show that aggregation of Fc alphaR on U937 cells and blood neutrophils results in tyrosine phosphorylation of several intracellular proteins, including the FcR gamma subunit, p72syk, and Bruton tyrosine kinase (...
Chemoimmunotherapy (CIT) has been the standard first-line treatment of patients with chronic lymphocytic leukemia (CLL). In the last several years, major strides have been made in understanding the biology of CLL, and fortunately, several of these discoveries are making their way into the clinics. These include novel CD20 monoclonal antibodies (mAb) (ofatumumab and obinutuzumab), Bruton tyrosin...
