    The antibody is an IgG1 kappa immunoglobulin containing murine light- and heavy-chain variable region sequences and human constant region sequences.10 The Fab domain of rituximab binds to the CD20 antigen on B lymphocytes, and the Fc domain recruits immune effector functions to mediate B-cell lysis in vitro. Possible mechanisms of cell lysis. Development of anti-chimeric antibodies HACA that might rapidly reduce rituximab levels has been an uncommon finding in clinical trials, likely reflecting the human Fc portion as well as the. To the Editor. Rituximab is a chimeric mouse-human IgG1 monoclonal antibody that targets CD20, a transmembrane protein expressed on B cells. It has demonstrated success in two prospective case series in pemphigus 1;2, a potentially fatal blistering disease caused by autoantibodies to desmoglein skin adhesion proteins.

Depletion of either NK cells or neutrophils or both in tumor-injected animals does not affect the therapeutic activity of the drug. Mar 12, 2018 Rituximab MabThera; Roche Pharmaceuticals is a chimeric mouse‐human monoclonal antibody against CD20. Once bound to CD20, rituximab affects B cell death, reducing pathogenic antibody production. Rituximab is used in a number of autoimmune diseases Townsend et al, 2010 including Thrombotic Thrombocytopenic Purpura TTP Scully et al, 2007. Rituximab a chimeric anti-CD20 monoclonal antibody is the first Food and Drug Administration approved anti-tumor antibody. Immunotherapy by rituximab, especially in combination-therapy, is a mainstay for a vast variety of B-cell malignancies therapy.
