UNLABELLED Antibodies that can neutralize diverse viral strains are likely to be an important component of a protective human immunodeficiency virus type 1 (HIV-1) vaccine. To this end, preclinical simian immunodeficiency virus (SIV)-based nonhuman primate immunization regimens have been designed to evaluate and enhance antibody-mediated protection. However, these trials often rely on a limited...
Two recombinant baculoviruses were produced in order to obtain a bovine viral diarrhea virus (BVDV) immunogen: AcNPV/E2 expressing E2 glycoprotein, and AcNPV/E0E1E2 expressing the polyprotein region coding for the three structural proteins of BVDV (E0, E1, and E2). Mice were immunized with Sf9 cells infected with the recombinant baculoviruses in a water in oil formulation and the production of ...
CONTEXT Despite enormous improvements achieved through the use of antiretroviral therapies (ARTs), the risk for eventual human immunodeficiency virus (HIV) disease progression remains high. Agents that enhance the immunologic mechanism for viral recognition might reduce disease progression. OBJECTIVE To determine whether the addition of HIV-1 Immunogen would confer added clinical efficacy to ...
Yersinia pseudotuberculosis mutants that overproduce the DNA adenine methylase (DamOP Yersinia) are attenuated, confer robust protective immune responses, and synthesize or secrete several Yersinia outer proteins (Yops) under conditions that are nonpermissive for synthesis and secretion in wild-type strains. To understand the molecular basis of immunity elicited by DamOP Yersinia, we investigat...
Using passively administered isotope-labeled anti-KLH to suppress the antibody response of rabbits to KLH, we have attempted to estimate the amount of antigen actually involved in stimulating antibody formation. Single and paired label tracer studies of passively administered anti-KLH IgG indicated that from 0.7 to 2.9 microg were utilized or involved by the antigen in the course of a 90% suppr...
The immunogenicity of Mycoplasma pneumoniae for New Zealand white female rabbits was studied by using an immunization scheme which employed initial intramuscular immunization with vaccine in incomplete Freund adjuvant followed 3 weeks later by a series of five intravenous injections of fluid vaccine. Small doses of immunogen (15 to 150 mug of mycoplasmic protein per rabbit) gave rise to sera wh...
Anti-cytokine therapeutic antibodies have been demonstrated to be effective in the treatment of several auto-immune disorders. However, The problems in antibody manufacture and the immunogenicity caused by multiple doses of antibodies inspire people to use auto-cytokine as immunogen to induce anti-cytokine antibodies. Nevertheless, the tolerance for inducing immune response against self-antigen...
The pivotal role played by antigen in the clonal selection of B cells for initial participation in an immune response is well established. Antigen selective mechanisms ensure that antigen-binding antibodies are produced during all stages of the immune response. However, antibodies that lack specificity for the immunogen might also be produced during the course of an antigen-driven immune respon...
