Engineered Jurkat Cells for Targeting Prostate-Specific Membrane Antigen on Prostate Cancer Cells by Nanobody-Based Chimeric Antigen Receptor
Background: Recently, modification of T cells with chimeric antigen receptor (CAR) has been an attractive approach for adoptive immunotherapy of cancers. Typically, CARs contain a single-chain variable domain fragment (scFv). Most often, scfvs are derived from a monoclonal antibody of murine origin and may be a trigger for host immune system that leads to the T-cell clearance. Nanobody is a spe...
متن کاملDevelopment of chimeric antigen receptor-redirected T cell therapy targeting L1-CAM in ovarian cancer
Ovarian cancer is responsible for the majority of gynecologic cancer deaths. Despite improvements in surgical approaches and the refinement of first-line cytotoxic combinations, the majority of patients diagnosed with advanced stage ovarian cancer eventually succumb to tumor recurrence. Thus, novel therapeutic approaches are desperately needed for this disease. With the growing recognition of t...
متن کاملGeneration and Characterization of Human Monoclonal Antibodies Targeting Anthrax Protective Antigen following Vaccination with a Recombinant Protective Antigen Vaccine.
The anthrax protective antigen (PA) is the central component of the three-part anthrax toxin, and it is the primary immunogenic component in the approved AVA anthrax vaccine and the "next-generation" recombinant PA (rPA) anthrax vaccines. Animal models have indicated that PA-specific antibodies (AB) are sufficient to protect against infection with Bacillus anthracis. In this study, we investiga...
متن کاملAnthrax protective antigen forms oligomers during intoxication of mammalian cells.
The protective antigen component (PA) of anthrax toxin binds to receptors on target cells and conveys the toxin's edema factor (EF) and lethal factor (LF) components into the cytoplasm. PA (83 kDa) is processed by a cellular protease, yielding a 63-kDa fragment (PA63), which binds EF and/or LF. When exposed to acidic pH, PA63 inserts into membranes and forms ion-conductive channels. By electron...
متن کاملAntigen-specific CD4+ T cells recognize epitopes of protective antigen following vaccination with an anthrax vaccine.
Detection of antigen-specific CD4+ T cells is facilitated by the use of fluorescently labeled soluble peptide-major histocompatibility complex (MHC) multimers which mirror the antigen specificity of T-cell receptor recognition. We have used soluble peptide-MHC class II tetramers containing peptides from the protective antigen (PA) of Bacillus anthracis to detect circulating T cells in periphera...
