The high mortality of nosocomial infections caused by Klebsiella spp. has acted as a stimulus to develop immunotherapeutic approaches targeted against surface molecules of these bacteria. Since O-antigen-specific antibodies may add to the protective effect of K antisera, we tested the functional and binding capacity of O-antigen-specific monoclonal antibodies (MAbs) raised against different Kle...
Abstract Maternal antibody-mediated fetal red blood cell destruction secondary to non-D Rh system antibodies is a significant cause of hemolytic disease the fetus and newborn. Here, we report rare case severe perinatal associated with maternal antibody e antigen. In addition anemia, infant developed hyperbilirubinemia. Resolution infant’s anemia hyperbilirubinemia occurred after treatment photo...
Introduction: Hepatitis D virus (HDV) is a 35 nm in diameter agent that depends on hepatitis B surface antigen in order to proliferate and accumulate. Infection with delta agent can occur spontaneously with hepatitis B virus infection and it cause acute hepatitis or develop as secondary infection in the patients with hepatitis B. Hepatitis D virus (HDV) has several genotypes based on genome seq...
Capsular polysaccharides are important factors in bacterial pathogenesis and have been the target of a number of successful vaccines. Francisella tularensis has been considered to express a capsular antigen but none has been isolated or characterized. We have developed a monoclonal antibody, 11B7, which recognizes the capsular polysaccharide of F. tularensis migrating on Western blot as a diffu...
Retroviral transfer of T-cell receptors (TCR) to peripheral blood–derived T cells generates large numbers of T cells with the same antigen specificity, potentially useful for adoptive immunotherapy. One drawback of this procedure is the formation of mixed TCR dimers with unknown specificities due to pairing of endogenous and introduced TCR chains. We investigated whether ;D T cells can be an al...
Molecular relationship of public H-2 antigens 1, 5, 6, 8, 11, 13, 25, and 28 to private antigens controlled by K and D regions was studied using the technique of antibody-induced resistance to complement-mediated cytotoxicity. The results indicate physical association in the cell membrane between H-2 antigens 1 and 23 of H-2-a, 8 and 31 of H-2-d, 11 and 17 of H-2-q, 13 and 30 of H-2-q, 25 and ...
Antigen arrays are becoming widely used tools for the characterization of the complexity of humoral immune responses. Current antibody profiling techniques provide modest and indirect information about the effector functions of the antibodies that bind to particular antigens. Here we introduce an antigen array-based approach for obtaining immune profiles reflecting antibody functionality. This ...
The structural and genetic organization of the Escherichia coli O52 O antigen was studied. As identified by sugar and methylation analysis and nuclear magnetic resonance spectroscopy, the O antigen of E. coli O52 has a partially O-acetylated disaccharide repeating unit (O unit) containing D-fucofuranose and 6-deoxy-D-manno-heptopyranose, as well as a minor 6-deoxy-3-O-methylhexose (most likely,...
