Immunopathogenesis studies employing West Nile virus (WNV) mice model are important for the development of antivirals and vaccines against WNV. Since antibodies produced in mice early during WNV infection are essential for clearing virus from the periphery, it is important to detect early and persistent anti-WNV antibodies. ELISA and plaque reduction neutralization tests are traditionally used ...

BACKGROUND/AIMS There is a critical need for more noninvasive biomarkers to identify nephritis in patients with systemic lupus erythematosus (SLE). Recent studies in a model mouse and an adult SLE patient cohort suggest that anti-basement membrane antibody levels correlate well with lupus activity and kidney injury. The purpose of this study was to assess the anti-basement membrane reactivity i...

HYPOTHESIS Blood group antibodies are natural antibodies that develop early in life in response to cross-reactive environmental antigens in the absence of antigen encounter. Even later in life structural similarities in saccharide composition between environmental antigens such as bacterial polysaccharides and blood group A/B antigens could lead to changes in serum levels, IgM/IgG isotype, and ...

Antisperm antibodies are detected in 3% to 25% of cases men and women diagnosed with infertility. They can also be 1–10% healthy fertile men. The presence a high titer AST is one the factors male infertility, which «hidden», i. e. not cause symptoms deterioration overall spermogram. objective: analyze results sperm testing antisperm antibodies, were by MAR-test. Material methods. A retrospectiv...

We assessed serologic responses to an oral, killed whole-cell enterotoxigenic Escherichia coli plus cholera toxin B-subunit (ETEC-rCTB) vaccine in 73 Egyptian adults, 105 schoolchildren, and 93 preschool children. Each subject received two doses of vaccine or placebo 2 weeks apart, giving blood before immunization and 7 days after each dose. Plasma antibodies to rCTB and four vaccine-shared col...

objectives: regarding the implication of viruses particularly herpes in pemphigus vulgaris, we sought to assess and compare the level of immunoglobulin g (igg) antibodies against herpes simplex virus types 1 and 2 (hsv1 and hsv2), cytomegalovirus (cmv) and epstein-barr virus (ebv) in patients with pemphigus vulgaris and healthy people.     materials and methods: in this cross-sectional study, 2...

Background: The ability of polyclonal antibodies to react with many epitopes of an antigen makes them valuable reagents in research and diagnosis. The aim of this study was purification of mouse IgG2a and production of polyclonal antibody against purified mouse IgG2a subclass. Materials and Methods: Mouse IgG2a was purified by ProA affinity. Verification method of the purified antibody was S...
