Pseudomonas aeruginosa is a significant human pathogen, and no vaccine is commercially available. Passive antibody prophylaxis using monoclonal antibodies (MAb) against protective P. aeruginosa epitopes is an alternative strategy for preventing P. aeruginosa infection, but mouse MAb are not suitable for use in humans. Polyclonal human antibodies from multiple donors have variable antibody titer...

Abstract Background Anterior uveitis (AU) is the most frequent extra-articular feature of axial spondyloarthritis (axSpA). We aimed to assess and compare incidence AU in axSpA patients treated with anti-TNF or anti-IL17A. Methods systematically reviewed PubMed, EMBase, Cochrane from inception May 3, 2020, searched for placebo-controlled head-to-head randomized controlled trials (RCTs) assessing...

In the early spring of 2013, Chinese health authorities reported several cases of H7N9 influenza virus infections in humans. Since then the virus has established itself at the human-animal interface in Eastern China and continues to cause several hundred infections annually. In order to characterize the antibody response to the H7N9 virus we generated several mouse monoclonal antibodies against...

Monoclonal antibodies (MAb) specific for citrus tristeza virus (CTV) were obtained from hybrid cells produced by fusion of a non-secreting myeloma cell line with spleen cells from BALB/c mice immunized with isolate T-308 of CTV. Three MAb were characterized for their immunoglobulin isotype and their titres in cell culture and ascites fluids. Each MAb was conjugated with alkaline phosphatase and...

Japanese encephalitis virus (JEV)-specific Fab antibodies were recovered by repertoire cloning from chimpanzees initially immunized with inactivated JE-VAX and then boosted with attenuated JEV SA14-14-2. From a panel of 11 Fabs recovered by different panning strategies, three highly potent neutralizing antibodies, termed Fabs A3, B2, and E3, which recognized spatially separated regions on the v...

The pro-inflammatory cytokine, TNF-α, which plays a major role in the development and persistence of inflammatory diseases, is the basis for the use of anti-TNF-α therapies. The neutralization of TNF-α or blockage of its binding to the corresponding receptor has mainly served as a therapeutic strategy against some diseases. This study aimed to investigate the production of a humanized single ch...

Cancer/testis (CT) antigens are expressed in several malignant tumors, but not in normal tissues except for testicular germ cells. The expression of CT antigenic proteins in malignant gammopathies has not been characterized. We examined the expression of a panel of CT antigenic proteins in 29 patients with malignant gammopathies by immunohistochemistry using the following monoclonal antibodies ...

N-acetyl-aspartyl-glutamate (NAAG) is a putative neuromodulator/neurotransmitter in the mammalian nervous system. Immunohistochemical studies with polyclonal NAAG antisera have revealed immunoreactive neurons and processes in several brain regions. However, these antisera crossreact to some degree with N-acetyl-aspartate (NAA), which is present in mM concentrations in brain, prompting the devel...

Pemphigus vulgaris is a potentially fatal autoimmune mucocutaneous disease associated with production of IgG autoantibodies to desmoglein 3, a 130 kDa epidermal protein. To further characterize the epitope(s) of Pemphigus vulgaris antigen we established two humanhuman hybridomas by fusion of the peripheral blood mononuclear cells with a human and mouse heterohybridoma. These hybridomas designat...

Cancer cells with immunogenic properties having altered protein glycosylation, modified blood group substances have been widely studied. Due to the genetic instability occurring during carcinogenesis glycosyltransferases may suffer from posttranslation sequence modification. The author describes 2 autopsy cases, where in background of unusual metastatic tumor presentation, incompatible antigeni...
