Obinutuzumab is a new anti-CD20 monoclonal antibody which demonstrated clinical superiority compared with rituximab in a recent phase III study. There is a need to better understand how this antibody...
B cells play a major role in the pathogenesis of many autoimmune disorders, including rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis, and type I diabetes mellitus, as indicated...
B cells are required for development of spontaneous autoimmune thyroiditis (SAT) in NOD.H-2h4 mice where they function as important APCs for activation of CD4(+) T cells. Depletion of B cells using an...
Rituximab, a chimeric monoclonal antibody against CD20, is increasingly used in the treatment of B-cell lymphomas and autoimmune conditions. Transient peripheral B cell depletion is expected following...
Amegakaryocytic thrombocytopenia (AMT) is a rare cause of acquired thrombocytopenia. The pathogenesis and treatment of AMT is not clearly known. Here we demonstrate a 50-year-old man presented with th...
High dose therapy with auto stem cell transplant increases the event-free survival in diffuse aggressive lymphomas and low grade lymphomas compared with conventional therapy. However, rela...
The purpose of this study is to determine the safety of the anti-CD20 antibody rituximab in treating patients with Sjogren's syndrome (SS). Rituximab is a laboratory-made antibody currentl...
This is a single-arm, open-label study of Iodine 131 Anti B1 Antibody for the treatment of 1st or 2nd relapsed indolent B cell lymphomas or B cell lymphomas that have transformed to a more...
This is a Phase I trial to look at safety and how a patient's body will tolerate the treatment at different dosages.
The protein engineering of AME-133v is hypothesized to result in an anti-CD20 therapy with greater potency and efficacy in all patients, but particularly in genetically defined subpopulati...
Medical and Biotech [MESH] Definitions
Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
A form of fluorescent antibody technique commonly used to detect serum antibodies and immune complexes in tissues and microorganisms in specimens from patients with infectious diseases. The technique involves formation of an antigen-antibody complex which is labeled with fluorescein-conjugated anti-immunoglobulin antibody. (From Bennington, Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984)
The in vitro formation of clusters consisting of a cell (usually a lymphocyte) surrounded by antigenic cells or antigen-bearing particles (usually erythrocytes, which may or may not be coated with antibody or antibody and complement). The rosette-forming cell may be an antibody-forming cell, a memory cell, a T-cell, a cell bearing surface cytophilic antibodies, or a monocyte possessing Fc receptors. Rosette formation can be used to identify specific populations of these cells.
A form of non-Hodgkin lymphoma having a usually diffuse pattern with both small and medium lymphocytes and small cleaved cells. It accounts for about 5% of adult non-Hodgkin lymphomas in the United States and Europe. The majority of mantle-cell lymphomas are associated with a t(11;14) translocation resulting in overexpression of the CYCLIN D1 gene (GENES, BCL-1).
The phenomenon of antibody-mediated target cell destruction by non-sensitized effector cells. The identity of the target cell varies, but it must possess surface IMMUNOGLOBULIN G whose Fc portion is intact. The effector cell is a "killer" cell possessing Fc receptors. It may be a lymphocyte lacking conventional B- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent.
