BACKGROUND Staphylococcus aureus is implicated in many opportunistic bacterial infections around the world. Rising antibiotic resistance and few alternative methods of treatment are just two looming problems associated with clinical management of S. aureus. Among numerous virulence factors produced by S. aureus, staphylococcal enterotoxin (SE) B is a secreted protein that binds T-cell receptor ...
A monoclonal antibody (mAb), AD1, was isolated that recognized a cell surface protein on rat basophilic leukemia cells (RBL-2H3). At high concentration, this antibody inhibited IgE-mediated but not calcium ionophore-induced histamine release (49% inhibition at 100 micrograms/ml). The mAb AD1 did not inhibit the binding of IgE or of several antibodies directed to the high affinity IgE receptor (...
Alpha-fetoprotein (AFP), a serum glycoprotein belonging to the onco-developmental proteins group, serves as a marker both in cancer research and in studies concerning fetal development and fetal pathophysiology. Monoclonal anti-AFP antibodies are essential reagents in developing appropriate techniques for measurement of this protein. In this study, in order to produce anti-AFP monoclonal a...
T-cell control of primary rotavirus infection and mucosal antibody responses to rotavirus was studied with monoclonal antibodies (MAb) to deplete gnotobiotic calves of CD4+, CD8+, BoWC1+, or both CD4+ and CD8+ lymphocytes prior to infection with rotavirus. Injection of these MAb produced specific reductions in circulating and tissue lymphocyte subpopulations. Following infection, control calves...
Two monoclonal antibodies (mAb) directed to the dual reactive cytolytic T lymphocyte clone OH8 (Db + H-Y and H-2d) were established. Analysis by cell surface staining and immunoprecipitation of radiolabeled surface molecules of OH8 followed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed that both mAb recognized an identical heterodimeric, clonotypic structure on OH8 cells...
Serum IgG is a potent inhibitor of monoclonal antibody (mAb) binding to the cell-surface Fcγ receptors (FcγRs), which mediate cytotoxic and phagocytic effector functions. Here, we show that this competition can be eliminated, selectively, by the introduction to serum of (i) an enzyme that displaces Fc from FcγRs and (ii) a modification present in the therapeutic mAb that renders it resistant to...
One concept for immune therapy of cancer involves induction of antigen mimic antibodies to trigger the immune response against tumor cells. Anti-idiotypic antibodies directed against the antigen-binding site of antibodies specific for tumor antigen may functionally and even structurally mimic antigen and induce anti-anti-idiotypic immune response. Monoclonal antibody WJ02 is one of such anti-id...
Four distinct epitopes (A, B1, B2, and C) have been functionally defined on the human alpha4 integrin. In this study, two cross-reactive antihuman alpha4 monoclonal antibodies (mAb) (HP2/1 and HP2/4 specific for epitopes B1 and B2, respectively) were used to functionally characterize the rat VLA-4 subunit and to define similar functional epitopes in this rodent species. It was found that B1 and...
Phenotypic characterization of cellular responses in equine infectious encephalitides has had limited description of both peripheral and resident cell populations in central nervous system (CNS) tissues due to limited species-specific reagents that react with formalin-fixed, paraffin embedded tissue (FFPE). This study identified a set of antibodies for investigating the immunopathology of infec...
Purpose: Monoclonal antibodies (mAb) that block programmed death (PD)-1 or cytotoxic T lymphocyte antigen (CTLA-4) receptors have been associated with durable clinical responses against a variety of cancer types and hold great potential as novel cancer therapeutics. Recent evidence suggest that targeted blockade of multiple immunosuppressive pathways can induce synergistic antitumor
